Why City & Suburban

Six reasons, each tied to something you can check rather than an adjective any contractor could type.

Founded in 1952

Seventy-four years on Chicago heating. Second-generation family ownership, and the owner still runs calls himself.

4.98 across 204 Google reviews

Not a rounded 5.0, and not an aggregate across platforms. One profile, 204 reviews, pulled 31 August 2026.

The owner turns up

Reviewers name Rob, Eddie, Carissa, Frank and Nate across the review file. You are not getting a rotating subcontractor.

Callbacks in minutes

One reviewer logged a callback within 10 minutes and an appointment the following morning. Thirty-three of the 204 reviews cite a specific response time.

No commission, no upsell script

Multiple reviewers record being told their unit had life left in it. A second opinion here is a second opinion, not a sales call.

We work the heating side of your hot water

A tank swap disturbs the shared flue, the gas line and the furnace draught. That is our trade, and we coordinate the plumbing rather than pretend it is ours.

What Drives the Price

We do not publish a price book and we are not going to invent one here. What follows is the permit record and the cost drivers, so you can read any quote you receive - ours or anyone else's.

Gas tank replacement, 40-50 gal

Venting route, gas line size, whether the flue is shared with the furnace Permit required

Power-vent or direct-vent conversion

Sidewall penetration, condensate route, electrical outlet at the unit Permit required

Tankless conversion

Gas line upsizing is the real cost, not the appliance Permit required

No hot water - repair

Thermocouple, gas valve, igniter or element. Diagnosis first, parts second No permit

Draught and venting correction

Shared masonry flue, spillage at the draught hood, liner condition Depends on scope

Furnace-side work after a swap

Re-sizing or relining a flue the two appliances share Depends on scope

The 445 Chicago permits mentioning water heater work carry a median reported construction value of $8,500. Read that carefully: it is the declared value of the whole permitted project, which frequently bundles other work, not the cost of a water heater. Context, not a quote.

Water Heater Types We Work On

Chicago basements hold a narrower range than the catalogues suggest. These eight cover almost everything we meet, and the flue arrangement matters more than the badge.

Atmospheric-vent gas tank

Draughts up an existing chimney. The default in Chicago basements

Power-vent gas tank

Fan-assisted, vents out a sidewall when no flue is available

Direct-vent gas tank

Sealed combustion, draws its own air from outside

Electric tank

No flue, no gas. Common in condos and converted units

Tankless gas

Wall-hung, endless hot water, needs gas and venting upsized

Indirect cylinder

Heated by your boiler. The answer in steam and hot-water homes

Combi boiler

Heat and hot water from one wall unit, no cylinder

Expansion tank & venting

The parts an inspector fails you on, fitted as part of the job

The type you have is usually decided by your flue, not your preference. 98,849 Chicago properties run hot water or steam heat, and in those homes an indirect cylinder off the boiler is often cheaper than a standalone tank.

What Chicago customers say

Each card uses a short verbatim excerpt from the linked Google review, followed by a service-specific summary. Reviews were verified 31 August 2026.

Rob coordinated seamlessly with my plumber to ensure everything was handled efficiently and correctly
amy darling

The customer describes years of repair and maintenance support. When a water-heater replacement also required furnace adjustments, Rob coordinated directly with the plumber and kept the work clear and efficient.

had my ac, furnace, and water heater replaced yesterday
Todd Feitl

After first calling for a second opinion, the customer later hired City & Suburban to replace the air conditioner, furnace, and water heater. They praised the pricing, professionalism, workmanship, and attention to detail.

He was on time, polite and did an amazing job
Duane Jolly

This Wicker Park customer records a punctual, polite visit and says Rob completed the work to a high standard. It is general service proof and does not identify the equipment serviced.

Water Heater Repair & Installation questions

My water heater is leaking. Do I actually need a new one?

If it is weeping from the tank seam, yes - a tank leak is not repairable. If it is dripping from the T&P valve, a fitting or the drain valve, that is a part, not a unit. Ask for the failure point in writing before you accept any replacement quote.

Do you replace the water heater itself, or only the heating side?

Confirm this with us on the phone. Our review record shows both patterns - one customer had the AC, furnace and water heater all replaced, another had us coordinate with their plumber while we handled the furnace adjustments the swap forced. Chicago licenses plumbing and ventilation separately, and we would rather tell you who does what up front.

Does a water heater replacement need a permit in Chicago?

Yes. The city recorded 445 permits mentioning water heater work in the 24 months to August 2026. Repairs and part swaps do not need one. If a contractor tells you a full replacement needs no permit, get another quote.

Is tankless worth it in a Chicago two-flat?

Often not, and the reason is the gas line rather than the appliance. Tankless draws far more gas at peak, so the line back to the meter usually has to be upsized - and in a masonry two-flat that run is the expensive part. Ask for the gas line assessment before you compare appliance prices.

How fast can you get here if there is no hot water?

Same day is common in our review record and next morning is the norm. We do not publish a guaranteed response window, and you should treat any contractor who does with suspicion in a Chicago January.

Which Chicago neighbourhoods do you cover?

Chicago citywide, plus the near north and northwest suburbs. Ask us for our current municipal registrations before you book anything outside the city - we will give you the list rather than a marketing map.

My building is a pre-war two-flat. Does that change the job?

Usually yes. West Chicago township, covering Wicker Park and West Town, is 83.0% pre-1940. In stock that age the masonry flue and the lack of duct routes are the variables that decide the price.

Do you work in condo buildings?

Yes, though associations frequently have their own rules on venting, roof access and shutoffs. Get those requirements in writing before you book anyone.

Chicago housing stock

Cook County Assessor data for the eight townships covering Chicago: 439,398 assessed properties - 305,736 single-family, 133,662 multi-family.

335,769 run a warm air furnace and 98,849 run hot water or steam. 306,261 have no central A/C at all, against 133,080 that do. 324,305 have a full basement.

Age is the variable that decides most jobs. West Chicago township - Wicker Park and West Town - is 83.0% pre-1940, the oldest stock in the city. Jefferson township, the bungalow belt, is the largest at 112,923 properties with a median year built of 1927.

What actually needs a permit

Chicago issued 62,810 permits of all types in the 24 months to August 2026. 4,888 mention HVAC work - about 204 a month.

Equipment replacement needs a permit. Repair, diagnosis, maintenance and refrigerant work do not. That is why the permit file records almost none of the HVAC work that actually happens in this city.

It also means a contractor's permit count measures their construction volume, not their service volume. 1,539 firms pulled a Chicago HVAC permit in those 24 months. Most of them will never take a no-heat call in January. Read a permit boast for what it is.

Where we work

Chicago, plus the near north and northwest suburbs.

We are not going to print a coverage map listing suburbs we cannot evidence a current registration for. Municipal registration is checkable and it lapses. Ask us which suburbs we are currently registered in and we will tell you the list.

The shared flue problem

This is the water heater issue specific to Chicago's building stock, and the reason a heating company should look at your swap.

In a typical bungalow or two-flat the furnace and the water heater both vent into one masonry chimney sized for the pair. Replace the water heater with a power-vent unit that exits a sidewall, and the furnace is left venting alone into an oversized, cold flue. Gases cool, condense, and attack the liner. At worst the furnace spills combustion products into the basement.

The fix is usually a correctly sized liner. It is cheap when planned and expensive when discovered. A quote covering only the appliance and the water connections is an incomplete quote.

Call and you will speak to the people who will do the work. Same-day is common, next morning is normal, and we will tell you on the phone whether this is our job or your plumber's.
