Air Duct Cleaning, Repair & Sealing in Chicago

Chicago recorded 299 permits mentioning ductwork in the 24 months to August 2026, about 12.5 a month. Cleaning, leakage diagnostics, balancing, and minor repairs usually do not require a permit; new trunks, ductwork replacement and major alterations usually do. In air duct cleaning and repair, the first question is whether the symptom comes from dirty ductwork, leakage, or an airflow problem at the equipment. A useful assessment keeps a homeowner from paying for clean ducts while a return leak, dirty coil or crushed branch remains untouched.

Pricing

What determines air duct cleaning, repair & sealing cost?

This is not a price book. It shows the scope variables and what the Chicago permit record can and cannot support so cleaning, sealing and duct replacement quotes can be compared fairly on the same basis.

Airflow and leakage diagnosisAccess, number of zones, static-pressure testing, and visible disconnections. No permit.
Targeted sealingJoint access, duct material, insulation removal, and repair area. Usually no permit.
Whole-system cleaningNumber of returns and supplies, contamination type, and access. No permit.
Branch repair or replacementRun length, ceiling access, fire stopping, and balancing. Depends on scope.
New trunk or major alterationDesign, sheet-metal fabrication, equipment airflow, and finishes. Permit usually required.

Financing available

Wells Fargo Home Projects credit card, subject to credit approval.

Duct repair and cleaning should be quoted from access, system size, and measured condition. When you compare quotes from an air duct cleaning company, look at the number of trunks, returns and supplies, required access panels, contamination evidence, sealing locations and post-work verification. A low headline price often excludes return ducts, inaccessible branches or restoration of cut openings, so ask what is included.

Equipment types

Air Duct Cleaning, Repair & Sealing by configuration

These are the configurations that change diagnosis, ductwork installation, safety, and the responsible trade for each part.

Sheet-metal trunk and branch

Durable Chicago basement ductwork; joints, dampers, and takeoffs drive leakage.

Flexible duct

Useful for short runs when supported and sized correctly; crushed flex starves airflow.

Duct board

Insulated panels that need careful sealing and moisture inspection.

Return-air pathway

Often the real cause of room pressure, noise, and comfort complaints.

Supply registers and dampers

The final delivery points; balancing begins only after system airflow is verified.

Dryer duct

A separate fire-safety scope that should not be confused with HVAC supply and return cleaning.

Equipment names we see

Fiberglass duct board
Mastic-sealed joints
Foil-tape systems
Manual dampers
Return-air grilles
Register boots

Ductwork is specified by material, size, pressure class, insulation, and sealant rather than by a consumer-facing brand. A useful proposal names the duct material, leakage point, insulation value, and access plan instead of leaning on a product badge. Ask the proposal to name the cleaning method, access openings, sealant, restoration of insulation and verification step. Fogging a product into an unidentified duct system is not a substitute for locating the contaminant or leakage source.

Cleaning is not the automatic answer

Dust at a register can come from return leaks, construction debris, a missing filter rack seal, or the room itself. A good assessment identifies where the dust comes from before cleaning or an air duct sealing service is recommended, so the money goes to the cause.

Before the visit

A sound assessment tests the airflow path before any treatment is sold. Supply and return sides must be evaluated separately. Return leakage can pull basement or wall-cavity dust into the system, while supply leakage loses conditioned air. A duct cleaning service that skips sealing the responsible side can leave the complaint coming back immediately.

Air Duct Cleaning, Repair & Sealing questions

How do I know whether my ducts need cleaning?

Look for a documented contaminant or debris source, not a calendar. Ask for before-and-after evidence inside representative trunks and returns.

Will duct cleaning fix weak airflow?

Not if the cause is a closed damper, crushed flex, undersized return, dirty coil, or weak blower. Airflow testing should come first.

Does duct sealing need a permit?

Minor joint sealing usually does not. New trunks, substantial rerouting, or work tied to a permitted equipment replacement may.

Can mold be removed from ducts?

First confirm whether growth is present and correct the moisture source. Coating or cleaning a wet system without solving condensation is temporary.

Is dryer-vent cleaning the same service?

No. Dryer ducts are a separate exhaust and fire-safety system. That scope should be confirmed when booking.

Should every register be cleaned?

If whole-system cleaning is justified, the scope should identify supplies, returns, trunks, blower compartment and coil protection. Cleaning visible registers alone changes appearance but does not document the condition of the air path.
