How to choose an air duct cleaning company.

A step by step guide to help you choose the right air duct cleaning company.


In today’s well-sealed homes when particles, pollutions, chemicals, and mold spores get in they have trouble getting out. Be sure to keep your heating systems clean and well-maintained so your in-door air isn’t worse than the air outside!


How many years has the company been in the business? You don’t want a fly by night business touching your expensive HVAC equipment. Ask for their proof of licensing and bonding and liability insurance. Do they have contractor/public works licensing? Do they have local references? ask neighbors or co-workers about them.


Is the company certified by the National Air Duct Cleaning Association (NADCA) which has strict standards relating to training, equipment, cleaning procedures, and ethical behavior? Do they have experienced technicians that have earned the prestigious ASCS (Air Systems Cleaning Specialists) designation, as well as CVI (Certified Ventilation Inspector) VSMR (Ventilation System Mold Remediator) duct cleaning certifications? Are they a member of the Better Business Bureau? If so, what is their rating? What is their Dun and Bradstreet rating?


Has this company provided you a competitive price? Beware of the $99 whole house special sales gimmick.

Is this a sideline service for them?

Beware of the low duct cleaning pricing if their real business is selling equipment and furnace parts. Make you sure have a bid from another heating dealer before letting yourself fall into this sales gimmick. Have a complete list of all major components of your HVAC system you want cleaned before the cleaning begins.


Job safety should be a top priority, this means they employ the best practices for safety at all job sites. Ask the company for their safety ratings. Do they use environmentally friendly non-toxic air purification products?

Quality Control

Ask about their QC policies. Have they done customer surveys on every residential jobsite? To assure quality control, larger projects need completely reports for the facility or project manager.

Do Your Research

Get your money’s worth. Check references. Businesses come and go, so ask how long has the company been in business?
