Having your ductwork cleaned can be a good thing. With the arrival of spring some of us throw open the windows and start cleaning everywhere, but it’s probably best to find a pro for ducts. They have the right equipment and training to do a thorough job.
If you think the ductwork in your home needs a tune up, it pays to do a little homework first and ask why. Are they musty or dusty? Do they go through a crawlspace, basement or attic? Will you be fixing the problem or just a symptom?
Duct cleaning is not a cure all, and in some cases, unsubstantiated claims are made from contractors taking advantage of our fears of mold and poor indoor air quality. Some unscrupulous contractors present pricing so high that for the same price you could get a new set of ducts installed instead! I’d suggest finding someone who understands that ductwork is part of a house as a system. In other words choose a home performance contractor to do the work, since cleaning ducts won’t help if they constantly pull dirty air from attics and crawlspace every time they run. That’s treating the symptom and not the problem.
Take a look at what the EPA has to say and do it for the right reasons, and have them cleaned knowing you are doing the right thing!
