The EPA puts duct cleaning at $450 to $1,000 per system and says it has never been shown to prevent health problems.

The EPA recommends cleaning ducts in three situations: substantial visible mold growth inside hard-surface ducts, infestation with rodents or insects, and ducts so clogged with dust that particles are released into the home. Outside those, the EPA says duct cleaning has never been shown to actually prevent health problems, and that research has not demonstrated that dirty ducts raise particle levels in the home (EPA duct cleaning).
The EPA gives $450 to $1,000 per heating and cooling system as the usual price, depending on size, access and contamination (EPA duct cleaning). Its red flags: sweeping health claims, routine cleaning sold as maintenance, and a claim of EPA certification, since the EPA neither sets duct cleaning standards nor certifies companies. It also warns about biocides and sealants, whose effectiveness and health effects research has not demonstrated, and notes there are no EPA-registered biocides for fiberglass ducts (EPA duct cleaning).
Dusty houses often have a duct leak, not a duct cleaning problem. ENERGY STAR says leaky ducts can pull particles and air from attics and crawl spaces and distribute them through the house, and that sealing the ducts may be the solution to excess dust (ENERGY STAR replacement guide). That is why the ducts page carries a price and this one carries a warning.
Simplified drawing, not to scale. Real systems vary: the indoor unit can sit in an attic or closet, the ducts can run in the attic or under the floor. Original illustration, not a photo.
Compare the cleaning quote to the EPA's $450 to $1,000 range (EPA duct cleaning) and to a duct repair. Ducts as a whole reported a median $6,500 for replacement work, 54 percent of a Florida full system. If a sealing job costs less than a cleaning and fixes the dust, it is the better use of money.
For dust, do the free steps first: change the filter and check that your return and supply vents are open. Our not-cooling and short-cycling pages cover the airflow causes that make a house feel stuffy.

No utility rebate in our data pays for duct cleaning. Lakeland Electric's tune-up rebate includes a duct leak check among its required items, which is the more useful inspection.

The EPA says only in three cases: substantial visible mold, vermin infestation, or ducts clogged with dust that is released into the home. It says duct cleaning has never been shown to actually prevent health problems (EPA duct cleaning).
The EPA puts it at $450 to $1,000 per heating and cooling system (EPA duct cleaning). We have no homeowner-reported quotes of our own.
ENERGY STAR says leaky ducts can pull particles and air from attics and crawl spaces and spread them, and that sealing ducts may be the answer (ENERGY STAR replacement guide). Check the filter first.
No. The EPA says it neither establishes duct cleaning standards nor certifies companies (EPA duct cleaning).
