How often should air ducts be cleaned?
Many HVAC pros suggest every 3 to 5 years, sooner with pets, allergies or after a renovation. The EPA doesn't recommend routine duct cleaning, but suggests it when there's visible mold, signs of pests, or dust and debris blowing out of the vents. Dryer vents are different: clean them at least once a year.
Avoid duct cleaning scams
- Be wary of very cheap whole-house offers, which are often used to get in the door and upsell.
- Ask for a written quote that says how many vents and systems are included.
- Ask to see before and after photos of the ducts.
- Don't agree to chemical treatments or mold work without proof there's a problem.
For duct cleaning businesses
Quote by home size or vent count, list each system separately, and offer the dryer vent as a bundled add-on, since it's quick extra revenue on the same visit. Check what the job pays per crew hour with the calculator above.
