Air duct cleaning questions Connecticut homeowners ask

Pinned

How do I choose an air duct cleaning company in Connecticut?

79 of the 85 Connecticut companies here hold 4.5 stars or better.

  • A written, itemized quote before work starts: what's included, any access fees, and no extras without your OK.
  • The scope covers the supply and return ducts, the blower and the coils, not just the vent covers.
  • Ask how debris is collected (negative-pressure collection) and how your ducts and home are protected.
  • Before-and-after photos of your own system.
  • Mold claims come with evidence, such as a sample or a test, before any chemical treatment.
  • Walk away from bait "whole-house" prices.
  • For repair or sealing work, check the contractor's Connecticut license with Connecticut's Department of Consumer Protection.

How we list providers

Connecticut air duct cleaning licensing and consumer rules

Connecticut doesn't license duct cleaning by name, but repairing or installing ductwork needs a state Heating, Piping and Cooling license.

Contractor licenses are issued by Connecticut's Department of Consumer Protection. Look up a license

Connecticut has no separate mold-remediation license; mold remediation on a home counts as a 'home improvement' needing Home Improvement Contractor registration.

Complaints about a Connecticut home improvement contractor or HVAC license holder go to the Department of Consumer Protection's Complaint Center.

Industry certification: NADCA (National Air Duct Cleaners Association)

Rules change. Check with Connecticut's Department of Consumer Protection before you hire for repair or HVAC work. Researched October 2026.
