If you ultimately decide to have your ducts cleaned, here’s how to hire a responsible company.
WHAT TO AVOID
Don’t hire a company that makes sweeping claims about health benefits or claims to be EPA-certified for duct cleaning: That agency offers no such certification.
Shop for a good price, but avoid companies that advertise specials under $200, or even under $100. Known in the industry as “blow-and-go” outfits, they will likely just hook up a vacuum to part of your duct system and do a poor job. Or use the low price as a bait-and-switch tactic.
WHAT TO LOOK FOR
Focus your search on contractors who belong to the National Air Duct Cleaners Association (NADCA), a nonprofit trade association. Ask for written proof of a company’s NADCA membership and certification, or use the NADCA website to locate members in your area. NADCA members must subscribe to the NADCA code of ethics. More important, they must employ at least one NADCA-trained-and-certified technician and employ NADCA-approved methods. Members must also carry at least $500,000 in general liability insurance.
Suggestions for Choosing a Duct Cleaning Service Provider
Do not assume that all duct cleaning service providers are equally knowledgeable and responsible. Talk to at least three different service providers and get written estimates before deciding whether to have your ducts cleaned.
Visit the National Air Duct Cleaners Association website
Visit the Better Business Bureau website
Ask the service provider proof of insurrance
Request an estimate of the number of hours the job will take
Written agreement outlining the total cost before work begins
