10 Best Air Duct Repair, Installation, and Maintenance Contractors in Chicago

 What Are the 10 Best Air Duct Repair, Installation, and Maintenance Contractors in Chicago in 2026?

City & Suburban Heating & Cooling leads this 2026 Chicago list because the owner performs the diagnosis himself, and repair is attempted before replacement is quoted. The rest, in order: Air Duct Maintenance Solutions LLC, EM Duct Cleaning Chicago, Eco Temp HVAC, Airflows Chicago, Mr. Duct Cleaning, Angel’s Duct Cleaning Services Chicago, Green Air Care, TNR, and Bernie’s Heating.

⚠️ The conflict, stated up front

I am Rob. City & Suburban Heating & Cooling is my company, and I have placed it at number one on this list.

You should discount that ranking accordingly, and I would rather say so in the first hundred words than bury it in a footnote. Read the criteria below, then check my company against them the same way you check the other nine.

If you pick a competitor from this list and the job goes well, this article did its job.

🧭 What I actually rank on

Most Chicago duct pages rank on star averages. Stars tell you whether people were pleased. They do not tell you whether anybody measured anything.

The US Department of Energy estimates that in a typical house, about 20 to 30 percent of the air moving through the duct system is lost through leaks, holes, and poorly connected joints. Until somebody proves your ducts are doing their job, be skeptical of any quote.

Our Evaluation Criteria

This title sits between two intents: duct services, and general contractor selection. I used the duct services criteria row and blended in licensing, pricing transparency, and coverage from the contractor row.

Here they are in weighted order, heaviest first.

⭐ 1. Diagnosis before quotation (highest weight)

Does the company measure static pressure, take a CFM25 leakage reading, or scope the duct before pricing the work? A photo of one dirty vent is a sales call, not an inspection.

This is weighted highest because it is the only criterion that predicts whether the money you spend fixes the problem you have.

✅ 2. Duct sealing versus duct cleaning capability

Cleaning removes debris. Sealing recovers lost air. Design and fabrication fix the room that has never been comfortable. These are three different jobs, and most Chicago companies do only one of them well. If your job is sealing rather than scrubbing, you want a contractor who treats duct repair and sealing as mechanical work.

📋 3. Licensing, permits, and Chicago code handling

Mechanical work in Chicago requires a permit, and it must comply with the Chicago Mechanical Code edition in force when the application is submitted. Every company below can be checked by name through the City of Chicago Contractor License Lookup.

💰 4. Pricing transparency and quote stability

Does the quoted number survive contact with the house? The most damaging failure in this trade is not a high price. It is a phone quote that doubles once the van is parked.

📊 5. Review record with volume and date range

A 5.0 average means nothing without a count and a time window. I report Google and Yelp separately, with their own counts, and I never merge them.

📍 6. Service area and housing-stock fit

A contractor who works Naperville new-builds is not the contractor for a 1918 two-flat with a shared chase. Check the company’s published Chicago service areas before you call.

Who This Guide Is For

• The homeowner with one room that has never been right, in any season.
• The homeowner holding a four or five figure replacement quote they do not trust.
• The owner of a pre-war bungalow, greystone, or worker cottage with ductwork retrofitted three times.
• The gut-rehab owner whose airflow got worse after the renovation.
• The small landlord with a two-flat or six-flat and ageing equipment.
• The small commercial manager with a rooftop unit and duct runs nobody has measured, which is usually a commercial HVAC job rather than a residential one.

The Shortlist at a Glance

1. City & Suburban Heating & Cooling: Best for duct repair and sealing when you want the owner, not a salesperson, doing the diagnosis.
2. Air Duct Maintenance Solutions LLC: Best for scope-documented residential duct cleaning with before and after footage.

🔧 Why this company is at number one, and what that is worth

City & Suburban has traded in Chicago since 1952, when my father started it going door to door offering furnace cleaning. I run it now as the second generation.

I perform the diagnosis myself on service calls. There is no commission-paid comfort advisor between you and the answer, which is why repair gets attempted before replacement gets quoted.

That is the whole proposition. It is also the only thing I can offer that a large consolidator structurally cannot.

📈 What the review record actually shows

Google’s own topic clustering across the 190 reviews surfaces “fair pricing” 27 times, “problem diagnosis” 14 times, and “no upselling” 5 times. That ordering matters more to me than the 5.0.

I should be honest about a limit here. The captured corpus contains no reviews below four stars, so I cannot show you a critical one from my own file.

Google also serves its most relevant reviews first, which skews every company on this list positive.

“Super responsive, knowledgeable and friendly with very fair prices and quality work. Have used them the last 2 years to recharge my AC refrigerant and never got up sold.”

– Brian Hughes, City & Suburban Heating & Cooling Google – Verified Review

“The whole C&S team have been wonderful both in servicing our original furnace and air conditioning systems and with a full HVAC replacement this spring. They are knowledgeable, clear in their assessments and communication, reliable, courteous and mindful of our budget and needs.”

– Raymond Fox, City & Suburban Heating & Cooling Google – Verified Review

🏠 Where the duct work actually happens

Most of my duct calls are in balloon-framed and gut-rehabbed homes. The recurring fault is an undersized return, which is the duct that carries air back to the furnace.

When the return is too small, static pressure climbs and the blower fights for every cubic foot. You feel that as a hot upstairs in July and a cold one in January.

We are an American Standard dealer, and our technicians are NATE-certified, which is a trade competency exam rather than a brand badge.

⚖️ The honest limit

City & Suburban is not a duct cleaning company, and I would not rank us first on a cleaning-only list. Our strength is repair, sealing, and ductwork design correction on Chicago’s older housing stock, backed by 74 years in the same city under the same family.

Air Duct Maintenance Solutions LLC

Duct services offered: air duct cleaning, HVAC duct and vent repair, dryer vent cleaning and repair.

Overall service scope: residential duct and vent cleaning, with incidental repair found during service.

When not to choose: your problem is airflow design rather than debris, or you need a licensed mechanical contractor to pull a permit and rebuild duct runs.

Contact: (773) 571-1891
Address: Chicago, IL 60618

🔍 Why this one ranks second

This is the company on the list that most clearly meets my first criterion, inside its own lane. Reviewers describe a snake scope used to record each duct before and after, not a single vent photographed to justify a package.

They also run the HEPA vacuum unit outside the house, pulling negative pressure so debris leaves rather than resettles. That is the correct method, and it is not universal in this trade.

The detail I find most telling is what they declined to sell.

“Documented with a snake scope how dirty each vent/duct were before and how clean they were after… HEPA vacuum unit was outside pulling negative pressure… Price was not cheap but quite reasonable for how thorough they cleaned (about $600 for my split level 3b/3b and 130 for dryer vent) and final price was in the quoted range with no up-sell or any last minute increases… Even checked my blower and told me it didn’t really need to be cleaned.”

🏢 What landlords and condo owners report

Dryer vent work shows up repeatedly in this company’s record, and it is a genuine safety job rather than an HVAC add-on. Lint accumulation in a long or hard-to-reach run is a fire risk.

One landlord describes before and after photographs, an explained fault, and a repair made during the same visit.

“They provided before-and-after photos, explained the issues they found, and even helped make a repair along the way. Most importantly, they helped prevent what could have become a fire hazard if left unaddressed. As a landlord, that peace of mind is invaluable.”

– Tina Li, Air Duct Maintenance Solutions LLC Google – Verified Review

⚠️ Read this before you book any cleaner

The EPA does not recommend routine duct cleaning. It recommends cleaning when there is substantial visible mould inside hard-surface ducts, a rodent or insect infestation, or ducts so clogged that debris is released from your supply registers. If your real concern is what you are breathing rather than what is in the duct, an indoor air quality test answers that question directly.

That caution is why the trade attracts so much suspicion online.

“Yes it’s a scam.. The EPA does not recommend duct cleaning.”

– r/hvacadvice, “Is duct cleaning a scam?” Reddit Thread

One comment thread is not consensus, and a company that scopes, documents, and tells you your blower is fine is not the operator that thread is describing. The distinction is method, not trade.

🧾 The honest limit

Air Duct Maintenance Solutions is a cleaning specialist. If your quote is above five hundred dollars and nobody has taken a static pressure reading, you may be buying the wrong job at the right price.

EM Duct Cleaning Chicago

Duct related services: air duct cleaning, HVAC system cleaning, and dryer vent work. Angle: best and top-rated, reviews-led.

Overall service scope: residential and rental duct cleaning at high volume.

Coverage area: Chicago, from a 6124 N Milwaukee Avenue base.

Equipment types: ducted forced-air residential systems.

Types of service: domestic, with rental and landlord work evidenced in reviews.

Rating: Google 5.0 across 2,320 reviews.

Pricing: not published as a rate card. Reviewers describe being given tiered options on site.

When to choose: you want a cleaning booked quickly, sometimes next day, with photo evidence of the duct interior.

When not to choose: your problem is a cold room or high bills. Cleaning will not fix airflow design, and this is not a mechanical contractor who pulls permits. That work sits with a duct repair and sealing contractor instead.

Address: 6124 N Milwaukee Ave #3, Chicago, IL 60646

📸 The one habit worth copying from their reviews

The reviews that matter here are the ones describing photographs taken inside the ductwork before work starts. That is the minimum standard you should demand from any cleaner, anywhere.

A landlord describes exactly that sequence on a rental property.

“Before beginning the cleaning, Xavier took photos inside the ductwork so I could see the condition of the system firsthand. I was genuinely surprised by the amount of dust, debris, and buildup that had accumulated over the years.”

– Mariahm Stephenson, EM Duct Cleaning Chicago Google – Verified Review

⏰ Speed is the real selling point

Next-day availability shows up more than once in this record. For a family with a newborn or a move-in deadline, that matters more than a rate card.

“Deon and Devon were excellent! Professional, quick, and very friendly. We have a newborn and a dog at home and they were very accommodating. EM Duct Cleaning was able to fit us in the very next day.”

– Lauren C, EM Duct Cleaning Chicago Google – Verified Review

⚠️ Read the review count carefully

A 5.0 across 2,320 reviews is an unusual figure in this trade. Google also serves its most relevant reviews first, which skews what you see toward the positive.

That is not an accusation. It is a reason to ask for the tiered pricing in writing before the crew starts, since multiple reviewers mention being given options on the day.

Eco Temp HVAC

Duct related services: HVAC duct and vent repair alongside full mechanical work. Angle: urgent and same-day response.

Overall service scope: HVAC repair and installation, radiant floor heating, heat pumps, thermostats, and water heaters.

Coverage area: Chicago, from a 60605 base.

Equipment types: ducted forced-air, heat pumps including ducted Mitsubishi Hyper Heat, and radiant heat.

Types of service: domestic and commercial.

Rating: Google 4.9 across 176 reviews.

Pricing: not publicly disclosed.

When to choose: you need duct and vent repair combined with equipment work, especially a heat pump conversion.

When not to choose: post-installation follow-up matters to you and you want it guaranteed. The critical reviews in this record are all about what happened after final payment.

Contact: (224) 253-8131
Address: 1210 S Indiana Ave Apt 4611, Chicago, IL 60605

🔧 Where this company is genuinely strong

Eco Temp is the only cleaning-adjacent name on this list with documented heat pump installation work. That matters if you are planning a conversion rather than a repair.

One reviewer describes a ducted Mitsubishi Hyper Heat system specified to their situation, with parts ordered ahead of the install date.

“Jordan matched us with a ducted Mitsubishi Hyper Heat heat pump and installed it keeping our needs in mind. The team ordered everything needed ahead of time and had a strong plan of work before they arrived.”

– David Lewis, Eco Temp HVAC Google – Verified Review

❌ The failure pattern you should price in

I include the critical review because it describes the exact risk in this trade. Not a bad install, but a follow-up that stopped once the invoice was paid.

“It has now been more than a week. We have called the company’s call center multiple times, and every time we are told our message will be forwarded and someone will call us back… A warranty only has value if a company responds when customers need service.”

– Wai Chan, 1 star, Eco Temp HVAC Google – Verified Review

One review is not a pattern, and the same record contains long-running happy customers. Ask who handles callbacks and get the answer before you pay the final invoice. An HVAC maintenance plan is one way to keep that relationship alive after the install.

Airflows Chicago

Duct related services: air duct repair and installation. Angle: search-visible duct repair and install enquiries.

Overall service scope: Not publicly disclosed beyond duct repair and installation.

Coverage area: Not publicly disclosed.

Equipment types: Not publicly disclosed.

Types of service: Not publicly disclosed.

Rating: Not publicly disclosed.

Pricing: Not publicly disclosed.

When to choose: you are gathering quotes for duct repair or a new duct run and want a third number for comparison.

When not to choose: you need verifiable third-party review evidence before letting someone into your house. There is none in the captured dataset for this company.

Contact: airflowschicago.com

🔎 Why a company with no review data still made the list

Airflows Chicago ranks organically on duct repair and install queries, which is how most readers will meet it. Ranking is not evidence of workmanship, and I will not pretend otherwise.

Before you call, run the company name through the City of Chicago Contractor License Lookup. That takes two minutes and tells you more than any homepage headline.

Mr. Duct Cleaning

Duct related services: air duct cleaning, dryer vent cleaning, and furnace servicing. Angle: best and top-rated, reviews-led.

Overall service scope: residential and multi-property duct and vent cleaning.

Coverage area: Chicago, from a 2037 W Belle Plaine Avenue base.

Equipment types: ducted forced-air systems, dryer vent runs, and furnaces.

Types of service: domestic and commercial, with property-manager accounts evidenced in reviews.

Rating: Google 4.8 across 567 reviews.

Pricing: one reviewer reports $810 for a three-unit premium package, with blower motor cleaning quoted separately at $200 per unit.

When to choose: you manage multiple units and need a vendor who answers follow-up questions without chasing.

When not to choose: you assume a premium package includes everything. Confirm in writing whether the blower motor is in scope.

Contact: (773) 477-2210
Address: 2037 W Belle Plaine Ave, Chicago, IL 60618

💸 The scope question that costs the most money

This is the clearest scope-exclusion story on the whole list, and it is worth reading before you buy any package anywhere.

“I paid for a three premium air duct cleaning service ($810), and after completion, I was informed that the technicians did not clean the blower motor… When I asked about this, I was told it would cost an additional $200 per unit for blower motor cleaning.”

– Eze 123, 1 star, Mr. Duct Cleaning Google – Verified Review

A three-star review adds a smaller but real complaint about housekeeping during the job.

“Good service but I was disappointed about the execution and details. Issues: 1. Shoes indoors… 2. Leftover dust: They had to cart the machine up and downstairs, which left residual dirt that I had to clean up.”

– Stephen S., 3 stars, Mr. Duct Cleaning Google – Verified Review

✅ What the record says they do well

Recovery is a real signal, and this company has it on file. One reviewer moved a one-star rating to five after a second technician returned and put the job right.

Property managers also report something rarer than good workmanship, which is a vendor who calls back with an answer. For portfolios, that reliability is usually written into a custom HVAC maintenance plan rather than left to goodwill.

“I am a property manager and its so rare that I don’t have to follow up over and over again with vendors.”

Angel’s Duct Cleaning Services Chicago

Duct related services: air duct cleaning, dryer vent cleaning and replacement, and vent rebalancing. Angle: best and top-rated, reviews-led.

Overall service scope: residential duct and dryer vent work, including behind-drywall vent replacement.

Coverage area: Chicago, from a 4467 W Lawrence Avenue base.

Equipment types: ducted forced-air systems and dryer vent runs.

Types of service: domestic and commercial, with multi-unit condo building contracts evidenced in reviews.

Rating: Google 4.8 across 472 reviews.

Pricing: not published. Reviewers report both competitive pricing and a phone quote that more than doubled on arrival.

When to choose: you have a dryer vent problem, especially one routed behind drywall or through a hard-to-reach wall.

When not to choose: you are accepting a price over the phone. Get it in writing, tied to a vent count, before anyone is dispatched.

Contact: (312) 785-4129
Address: 4467 W Lawrence Ave, Chicago, IL 60630

⚠️ The bait-and-switch complaint, quoted in full context

I am including this because it names the exact mechanism that damages homeowners in this trade.

“They quoted a price over the phone without ever seeing the home, and when they showed up, the actual cost was more than double. It felt like a classic bait and switch situation that forced me to make a quick decision on the spot… I was never shown before and after photos of the inside of the ducts.”

– Cameron Friend, 1 star, Angel’s Duct Cleaning Services Chicago Google – Verified Review

A four-star review points at the same theme in a milder form, which is why I trust it as a pattern rather than a one-off.

“I gave a 4 because a vent was broken and I was not informed. Some of the blue plastic used to cover vents was not removed and razor blades were left on the window sill in the dining room.”

– Mz. P, 4 stars, Angel’s Duct Cleaning Services Chicago Google – Verified Review

✅ Where they clearly earn their place

The strongest positive evidence here is airflow rebalancing, which is closer to real duct work than to cleaning. Two separate reviewers describe vents being adjusted for even flow across the house, and that is the same objective behind scheduled duct maintenance.

“Came out for a routine service, but found lots of problems… They were able to repair gaps in our pipes, removed tons of large debris from previous owners and construction. They also rebalanced our vents to make sure we get proper flow to all rooms. A bit pricey as we did not know how much work was involved.”

Green Air Care

Duct related services: air duct cleaning. Angle: best and top-rated, local pack visibility.

Overall service scope: duct cleaning, with published rebate handling for duct sealing and smart thermostats.

Coverage area: Not publicly disclosed.

Equipment types: ducted forced-air systems.

Types of service: Not publicly disclosed.

Rating: Not publicly disclosed.

Pricing: not published. The company’s own rebate page lists a ComEd duct sealing rebate of $200 and a smart thermostat rebate of $100.

When to choose: you are already comparing local-pack duct cleaners and want to ask about utility rebate paperwork.

When not to choose: you need documented review evidence, or a contractor who can also design and fabricate duct.

Contact: greenaircare.com

💰 Treat any rebate figure as a starting question, not an answer

A rebate number on a contractor’s own page is a self-claim, which is the weakest tier of evidence there is. Verify it against the utility programme itself before you count on the money.

Nicor Gas pays $600 per home for duct sealing in 2026, but only through a programme-approved contractor with pre-approval before work starts. ComEd’s weatherization rebate is performance-based at $2.00 per CFM25 of leakage reduced, capped at $500. If the goal is a lower bill rather than a cleaner duct, price energy-efficient HVAC upgrades against that rebate math first.

TNR

Duct related services: residential air duct cleaning, dryer vent cleaning, and NADCA-certified positioning. Angle: best and top-rated, published per-vent pricing.

Overall service scope: residential duct and dryer vent cleaning.

Coverage area: Chicago.

Equipment types: ducted forced-air residential systems and dryer vent runs.

Types of service: domestic and commercial.

Rating: Not publicly disclosed.

Pricing: the company publishes a residential rate of $7 per vent.

When to choose: you want a per-vent price you can multiply before anyone visits, and you value NADCA certification.

When not to choose: a very low per-vent headline is your only decision input. Count your vents, add the minimum charge, and ask what triggers an upcharge.

Contact: 4tnr.com

🧮 How to use a per-vent number without getting burned

Per-vent pricing is genuinely useful, because it lets you sanity-check any quote in your head. A twelve-register bungalow at $7 per vent is not the same as a twelve-register bungalow after a minimum call-out charge.

The homeowner forums are blunt about what a headline price often becomes.

“This is a scam.”

That is one thread and not a verdict on any company here. Use it as a reason to get the full scope in writing, including returns, trunk lines, and the dryer vent.

Bernie’s Heating

Duct related services: duct cleaning, duct repair, ductwork installation, and free camera inspection. Angle: best and top-rated, published itemised pricing.

Coverage area: Ravenswood, Portage Park, Jefferson Park, and the north side of Chicago.

Equipment types: ducted forced-air systems, dampers, and zoning.

Types of service: domestic and commercial.

Rating: Not publicly disclosed.

Pricing: published. Roughly $400 to $800 for cleaning, $200 to $400 per section for repair, and $100 to $250 per zone for damper work, with a free camera inspection.

When to choose: you are on the north side and want itemised numbers before you speak to anybody.

When not to choose: you are outside their stated north side coverage, or you need review evidence that is not in the captured dataset. Readers further north can check coverage in Rogers Park or Skokie before calling anyone.

⭐ The rarest thing on this list

This is the only company in the set publishing itemised duct repair pricing on its own site, including a free camera inspection before any sale. Published pricing is not proof of good work, but it removes the single biggest source of homeowner harm.

If you take one thing from this ranking, take the camera inspection. Ask every company on this list for one, and treat a refusal as an answer.

How I Evaluated These Companies

City & Suburban Heating & Cooling is my own company, and it sits at number one on a list I wrote. That is a conflict, and I said so in the opening rather than here at the bottom.

Here is exactly what I used, and what I could not verify.

• Used: a Chicago-localised Google capture from 8 August 2026 covering 30 organic results and 18 local pack results, plus the Google review permalinks attached to each profile.
• Used: published pricing pages, EPA and ENERGY STAR guidance, City of Chicago permit and licensing pages, and current ComEd and Nicor rebate documentation.
• Could not verify: review counts above roughly 1,000, which in this dataset are sometimes multi-location aggregates rather than a single Chicago branch.
• Could not verify: any response time, technician count, warranty term, or licence number, so none appears above.
• Known bias: Google serves its most relevant reviews first, which flatters every company here, including mine.

Four companies on this list have no review data in the captured set. Their ranking positions reflect search visibility only, and I have marked them accordingly rather than filling the gap with guesses.

Which Provider Should You Shortlist?

• No heat or no cooling today: call a mechanical contractor, not a cleaner. Describe the fault, not the equipment, when you book heater repair.
• A replacement quote you want checked: get a second diagnosis from someone with no commission attached to the answer.
• One room that has never been right: you need static pressure measured and the return sizing checked, not a cleaning.
• Moving into a Chicago home, or finishing a renovation: a scope-documenting cleaner like Air Duct Maintenance Solutions or EM Duct Cleaning fits the job.
• A dryer vent behind drywall or on a third floor: Angel’s Duct Cleaning and Air Duct Maintenance Solutions both have documented work of this kind.
• A six-flat or a portfolio of units: prioritise the vendor who answers follow-up calls, which is where Mr. Duct Cleaning’s property-manager reviews are strongest.
• North side and price-sensitive: Bernie’s Heating publishes itemised numbers you can compare before calling anyone.
• A condo or addition with no duct path at all: the answer is a ductless mini-split retrofit, not duct work.

City & Suburban Heating & Cooling holds 5.0 on Google across 190 reviews and 4.9 on Yelp across 251, captured August 2026, and Google’s own clustering of the Google corpus surfaces “fair pricing” 27 times and “no upselling” 5 times. Reach Rob on (773) 238-3838, or use the Schedule Service form.

Is It Your Furnace, or Is It Your Ductwork?

If one room is always wrong while the thermostat says the system is running, suspect the ducts before the box. The Department of Energy estimates that 20 to 30 percent of the air moving through a typical duct system is lost through leaks, holes, and poorly connected joints. Leaky ducts can cut system efficiency by as much as 20 percent.

The Room That Nobody Explains

Most replacement quotes I see start in the basement, standing next to the furnace. The complaint that brought the contractor out started upstairs, in a bedroom.

Those are two different problems. A furnace can be perfectly healthy while the air it produces never reaches the room you are paying to heat.

🔧 Why I take a pressure reading before I quote anything

Static pressure is the resistance the blower fights against as it pushes air through your ducts. Think of it as blood pressure for the system.

City & Suburban measures static pressure on the diagnosis, before any number gets written down. I do that because a high reading tells me the duct is choking the equipment, and no new furnace will fix that, whether the job ends in a duct repair or nothing at all.

🏠 The Chicago fault I find most often

In balloon-framed and gut-rehabbed homes, the return duct is usually too small. The return is the duct that carries air back to the furnace, and it is the half of the system nobody thinks about.

When the return is undersized, pressure climbs and airflow drops. You feel it as a hot upstairs in July and a cold one in January, which is the call we take most often in Bucktown and the surrounding pre-war blocks.

Three Tests You Can Run Today

You do not need tools for any of these. You need ten minutes and the blower running.

1. The slamming door test. Turn the system on. Walk the house and note which interior doors pull shut or swing on their own. That is air trying to find a return path that does not exist.
2. The hand test at every vent. Hold your palm over each supply register. Note which ones barely move air compared with the vent nearest the furnace.
3. The floor test. Ask which floor always feels wrong, in both seasons. A room that is hot in summer and cold in winter is an airflow problem, not a thermostat problem.

Write down what you find. That list is worth more to a good contractor than anything you can say about the equipment.

📏 The one sentence to say on the phone

Ask any bidder this: “Will you give me a duct leakage measurement in writing, before and after the work?”

The measurement is called CFM25, which is the volume of air leaking out of the duct system under a standard test pressure. It matters because ComEd’s weatherization rebate pays $2.00 per CFM25 of leakage removed, capped at $500. A contractor who cannot produce that number cannot claim the rebate for you.

⚠️ Photos of dirt are not a measurement

A photo of a dusty vent shows you a surface. A CFM25 number shows you a system.

Both can be honest, and neither is a substitute for the other. If the only evidence offered is a photo, you are being shown a symptom and sold a service.

The Analogy That Ends the Argument

Replacing the equipment without fixing the duct is like buying a new engine for a car with four flat tyres. The engine will run beautifully and the car will still handle badly.

I might be reading this harder than the trade average does, but City & Suburban’s Google review corpus surfaces “problem diagnosis” 14 times across 190 reviews, and that is the pattern I trust most. The owner does the diagnosis on the service call, so the airflow question gets asked before a heater installation number is written.

What Does Duct Repair, Cleaning and Ductwork Installation Actually Cost in Chicago?

Duct cleaning in Chicago typically runs $260 to $580, with Angi reporting a $325 average and roughly $400 to $800 for a 1,500 square foot bungalow with 12 registers. Per-vent pricing is $25 to $50 and hourly rates $90 to $125. Duct repair averages $200 to $800, or $200 to $400 per section, with dampers at $100 to $250 per zone.

The Published Numbers, Reconciled

Four sources give four different Chicago answers. That is not a conspiracy. It is what happens when nobody states the unit they are pricing.

💰 Two numbers you should distrust

ProMatcher publishes $418.59 for a typical two-storey Chicago home. Two decimal places on a market average is false precision, not accuracy.

The “$300 to $500 Chicago average” repeated across the local pack traces to contractor marketing pages, not to any dataset. I will not repeat a figure whose only source is somebody selling the service.

💸 What a cheap headline price actually becomes

Chicago vendors advertise $69 inspections and sub-$100 entry offers. Here is what to ask before the van is dispatched.

The exclusion problem is real, and one Chicago homeowner documented it precisely.

“I paid for a three premium air duct cleaning service ($810), and after completion, I was informed that the technicians did not clean the blower motor… I was told it would cost an additional $200 per unit for blower motor cleaning.”

– Eze 123, 1 star, Mr. Duct Cleaning Google – Verified Review

🏠 Why I will not price duct over the phone

Square footage is the weakest predictor of a Chicago duct price. Access is the strongest.

A bungalow with exposed basement duct is a different job from the same square footage with a finished basement and a boxed chase. City & Suburban gives free estimates and discloses the service call fee up front, credited against the repair, because a real number needs a real look. You can book that visit here.

⚖️ The evidence that a quote is a judgement

City & Suburban’s Yelp record, 4.9 across 251 reviews captured in August 2026, includes a near-total teardown billed at $164 and a repair resolved without replacing a part after a competitor had quoted $1,800. Those Yelp entries carry no individual permalinks, so treat them as narrative rather than as a clickable citation.

The Google side is checkable, and it says the same thing about pricing conduct.

“Super responsive, knowledgeable and friendly with very fair prices and quality work. Have used them the last 2 years to recharge my AC refrigerant and never got up sold.”

– Brian Hughes, City & Suburban Heating & Cooling Google – Verified Review

Benchmark every quote on unit price, never on the package headline. Count your vents, ask what a section means, and get the exclusions listed. The same discipline applies when you price air conditioning repair against a replacement.

Do You Need Cleaning, Sealing, or New Ductwork, and Which Trade Does Each?

The EPA recommends duct cleaning only when there is substantial visible mould inside hard-surface ducts, an infestation of rodents or insects, or ducts so clogged that debris is visibly released from supply registers. Otherwise routine cleaning is not recommended. Sealing addresses measurable air loss. New ductwork addresses design faults. Mould on fibrous duct insulation must be replaced, not cleaned.

Three Jobs, Three Different Trades

Searching “duct cleaning near me” and “duct work near me” returns the same local pack. The companies in it do not do the same job.

⚠️ The photo that sells the $900 job

Spotting on a boot, which is the metal box behind a wall vent, is a surface you can wipe in five minutes. It is not proof that an entire duct system needs cleaning.

Any company quoting a whole-home price from a photograph of one vent is running a sales call, not an inspection. That distinction is the single most useful thing in this article.

✅ What a real cleaning visit looks like

The method is what separates the trade from the racket. Look for the HEPA vacuum running outside under negative pressure, and a scope recording each run.

“Documented with a snake scope how dirty each vent/duct were before and how clean they were after… HEPA vacuum unit was outside pulling negative pressure… final price was in the quoted range with no up-sell or any last minute increases… Even checked my blower and told me it didn’t really need to be cleaned.”

– Samson Chan, Air Duct Maintenance Solutions LLC Google – Verified Review

Now the same job done badly, from the same city.

“They quoted a price over the phone without ever seeing the home, and when they showed up, the actual cost was more than double… I was never shown before and after photos of the inside of the ducts.”

– Cameron Friend, 1 star, Angel’s Duct Cleaning Services Chicago Google – Verified Review

❌ Why the forums are so hostile to this trade

Homeowners have learned to treat the whole category as suspect, which is unfair to the operators doing it properly.

“Yes it’s a scam.. The EPA does not recommend duct cleaning.”

– r/hvacadvice, “Is duct cleaning a scam?” Reddit Thread

One thread is not a verdict. It is a warning about method, and the method is checkable before you book.

🔥 Dryer vent work is a separate safety job

Lint in a long or hard-to-reach dryer run is a fire risk, not an air quality question. Price it separately, and do not let it be bundled in as a bonus on an HVAC package.

💰 The filter question, answered honestly

A high-MERV filter in a real four or five inch media cabinet is good engineering. The same filter crammed into a one-inch slot chokes the blower, like drinking through a coffee stirrer instead of a straw. If filtration is the actual goal, a whole-home air cleaner solves it without strangling the system.

Check your slot depth before you buy anything with health words on the box.

📋 What to refuse

• Sanitising or antimicrobial spray without documented mould.
• A UV light sold for growth you can reach and wipe by hand.
• Any scope of work that is verbal.

Sort the job first, then pick the trade. Buying the wrong one at a fair price is still the wrong purchase, and an indoor air quality test will tell you which job you actually have.

Why Does Chicago’s Older Housing Stock Break Ductwork, and What Does Correct Design Look Like?

In Chicago’s pre-war stock the recurring faults are undersized returns, half-abandoned octopus-furnace conversions, shared chases in two-flats and three-flats, and gut rehabs where a wall moved but the trunk line did not. A Manual J load calculation sizes equipment to the house. A Manual D calculation sizes the ducts to the equipment. Without both, capacity is a guess.

Four Houses, Four Failures

City & Suburban has worked this housing stock since 1952, from 1225 North Cleaver Street in West Town. That address sits inside the bungalow, two-flat, and greystone belt, which is why these four patterns are the ones I see most.

🏠 The bungalow with the abandoned octopus

Older bungalows were built around a gravity furnace with huge round arms, known in the trade as an octopus. When a forced-air furnace replaced it, some of those arms were often left in place and simply capped or forgotten.

The symptom is a front room that heats fine and a back bedroom that never does. The fix is a survey of what is actually connected, before anybody prices equipment.

🏢 The two-flat and three-flat with a shared chase

A chase is the hollow vertical run that carries duct between floors. In many two-flats and three-flats it was shared, then divided badly during conversion.

Owners report one unit cooking while the other freezes. Balancing that needs dampers and measurement, not a bigger furnace.

🧱 The greystone or worker cottage with a hundred years of retrofits

These systems have usually been touched by three or four contractors across a century. Each one solved the immediate problem and left the design worse.

The tell is a duct layout nobody can explain. I look for branch sizing first, because that is where the wrong number hides, and it is the first thing checked on a boiler service in a house of this age.

🔨 The gut rehab where the wall moved and the trunk did not

This is the most common call I get in Wicker Park, Bucktown, and Logan Square. The kitchen opened up, the bedroom shifted, and the main trunk line stayed exactly where it was in 1925.

Airflow after a renovation is often worse than before it. That surprises people, and it should not.

📏 The branch number that explains the bad room

Duct fittings carry sizes, and those sizes are not decoration. A branch that should be an eight-inch run leaving a main can turn out to be a six.

Once you see a six where an eight belongs, the cold room is no longer a mystery. It is arithmetic.

What Correct Design Actually Requires

Three ACCA calculations govern this work, and they are not optional.

• Manual J sizes equipment to the actual house, using construction, windows, insulation, and orientation.
• Manual S selects the specific equipment that matches that load.
• Manual D sizes and lays out the duct so the equipment can deliver it.

Skipping them produces oversized systems that short-cycle, which means switching on and off too quickly. Short-cycling wears parts, never dehumidifies properly, and shortens equipment life. That is why air conditioning installation should always start with the load report, not the tonnage.

✅ What good rebalancing looks like from the customer side

Chicago homeowners do notice when someone finally measures and adjusts flow rather than selling a box.

“They were able to repair gaps in our pipes, removed tons of large debris from previous owners and construction. They also rebalanced our vents to make sure we get proper flow to all rooms. A bit pricey as we did not know how much work was involved, but very happy with the result.”

– Eugene Lorman, Angel’s Duct Cleaning Services Chicago Google – Verified Review

“Gustavo and Jesus were communicative, thorough, and optimized our vents for a more balanced flow throughout the house.”

– Theo Apostol, Angel’s Duct Cleaning Services Chicago Google – Verified Review

⚠️ The question that ends a bad quote

Ask this: “Did you perform a Manual J load calculation, and can I see the printed report?”

A tonnage figure is not an answer. A printed report is.

City & Suburban runs the load calculation before quoting capacity, and the review record includes cases where the honest answer was that no new equipment was needed at all.

What Licences, Permits and Rebate Approvals Decide Who Can Legally Touch Your Ducts?

Mechanical work in Chicago requires a permit and must comply with the Chicago Mechanical Code edition in force when the application is submitted. Permit fees commonly appear on invoices at $50 to $300. Nicor Gas pays $600 per home for duct sealing in 2026, but only through a programme-approved contractor with pre-approval before work starts. ComEd pays $2.00 per CFM25 reduced, capped at $500.

The Paperwork Is the Filter

Most homeowners treat permits as an annoyance and rebates as a discount. Both are actually screening tools that tell you who is qualified before you hand anyone a deposit.

📋 Why an unpermitted duct job costs more later

Duct alterations without a permit tend to surface at the worst moment, usually during a sale or an insurance claim. The buyer’s inspector asks for the closed permit and there is nothing to show.

City & Suburban pulls the mechanical permit as part of the job rather than leaving it with the homeowner. A contractor who suggests skipping it is telling you something about the rest of the work, whether that work is a duct maintenance visit or a full rebuild.

🔎 The two-minute check that eliminates bad bidders

The City of Chicago Department of Buildings runs a public Contractor License Lookup. Type the company name and see what comes back.

Do this before the deposit, not after the dispute. Illinois licensing can also be checked through the Department of Financial and Professional Regulation.

Rebate Money Follows the Contractor, Not the Equipment

This is the part almost nobody gets right. You do not qualify for a duct sealing rebate by buying duct sealing.

Nicor Gas requires the work be done by a programme-approved contractor holding one of a short list of certifications, including Aeroseal, Duct Envelope Tightness, BPI Infiltration and Duct Leakage, or RESNET. Pre-approval must be secured before work begins, with photographs submitted before and after.

💰 What the two utilities actually pay in 2026

ComEd’s structure is the important one. Because it pays per unit of leakage removed, measurement stops being optional and becomes the invoice. The same logic drives most energy-efficient HVAC upgrades on the commercial side.

⚠️ Funding is not permanent

Some Illinois envelope rebate funding ran out mid-year in 2025. Treat any published figure as current until the programme year closes, not as a guarantee.

That is a reason to start the paperwork early, not a reason to rush a decision.

Your Four-Step Sequence

1. Run every shortlisted company through the City of Chicago Contractor License Lookup.
2. Get it in writing that the contractor pulls the mechanical permit and schedules the inspection.
3. Filter the Nicor Gas Find a Contractor tool by duct sealing and your ZIP code, then request pre-approval before work starts.
4. Ask each bidder to quote the rebate value implied by their projected CFM25 reduction.

That last question is the sharpest one in this article. A contractor who cannot project a leakage number cannot claim performance-based rebate money on your behalf.

City & Suburban works the ComEd and Nicor Gas paperwork into the quote conversation rather than treating it as an afterthought, and the company can be verified by name through the same public licence lookup as everyone else on this list.

What Should You Ask Before You Sign a Ductwork Quote?

Ask six things: did you take a static pressure reading, was a Manual J and Manual D performed, will you show me scope footage or a CFM25 number, who pulls the mechanical permit, is this quote fixed or subject to on-site revision, and what would you tell me not to buy. City & Suburban’s Google review corpus surfaces “no upselling” 5 times and “honest assessment” 4 times across 190 reviews, which is what a good answer to question six looks like in practice.

The Six Questions

You will be asked to decide with somebody standing in your basement. Print this list and keep it near the furnace.

1. Did you take a static pressure reading? If no measurement was taken, the quote is an opinion.
2. Was a Manual J and Manual D calculation performed? Ask for the printed report, not a tonnage number.
3. Will you show me camera footage or a duct leakage number? Photos of dirt are a symptom, not a diagnosis.
4. Who pulls the mechanical permit? Get the answer in writing before signing.
5. Is this price fixed, or can it change on site? This is where most homeowner harm happens.
6. What would you tell me not to buy? A diagnostician has an answer. A salesperson does not.

❌ Question five exists because of this

The phone quote that doubles on arrival is not rare, and it is documented in Chicago.

“They quoted a price over the phone without ever seeing the home, and when they showed up, the actual cost was more than double. It felt like a classic bait and switch situation that forced me to make a quick decision on the spot.”

– Cameron Friend, 1 star, Angel’s Duct Cleaning Services Chicago Google – Verified Review

⚠️ Ask what happens after the invoice is paid

Warranty language is worth nothing if nobody answers the phone. One Chicago homeowner recorded exactly that gap.

“We have called the company’s call center multiple times, and every time we are told our message will be forwarded and someone will call us back… A warranty only has value if a company responds when customers need service.”

– Wai Chan, 1 star, Eco Temp HVAC Google – Verified Review

A heater maintenance relationship is the simplest test of whether a company still picks up once the invoice is settled.

✅ What a good answer to question six sounds like

A woman I visited had already collected three quotes. Three contractors had walked her house for twenty minutes each and handed her a number.

I asked her one thing. Did she know why her upstairs was always hot in summer and freezing in winter? She said nobody had ever asked her that before.

That question was free, and it changed what she bought.

💰 Compare two written quotes, not four verbal ones

Get two quotes in writing, then compare them on unit price and scope, never on the headline total. Count the vents, define what a section means, and demand the exclusion list.

City & Suburban’s own record answers question six the hard way, with a repair resolved after a competitor quoted $1,800, a $7,000 furnace hard-sell declined, and a customer talked out of a new furnace by the owner. You can read the background on the family business before you call.

What I Am Still Sitting With

The thing I have not resolved is whether measurement will ever become normal in residential duct work. ComEd now pays per unit of leakage removed, which finally puts money behind a number instead of a photograph.

My guess is that performance-based rebates do more to clean up this trade than any licensing rule will. I could be wrong, and I would genuinely like to hear from Chicago homeowners who have had a contractor produce a before and after leakage figure.

If you have a quote you want a second opinion on, call (773) 238-3838 and describe the room, not the equipment. The Schedule Service form works when it is not urgent, and the same team handles commercial HVAC enquiries.
