Booking a "duct cleaning" can leave the dirtiest parts of your heating and cooling system completely untouched.
Air duct cleaning is an unregulated industry. That means two companies quoting you for the same job can deliver completely different work, and many homeowners compare quotes on price alone without realizing the cheaper option often skips the furnace entirely.
Cleaning the metal duct runs isn't the whole job. The real contamination lives inside the blower, the reheat coils, the heat exchanger, and the AC coils. If those aren't touched, dust and debris keep recirculating through your home.
The Qualified Air Duct Cleaners Affiliation (QUADCA) maintains strict verification standards so consumers know what they're paying for. Our members are certified to clean the entire HVAC system, not just the ducts.
Before you hire your next technician, verify their credentials and confirm they clean the full system.
