Eight months of heating pushes a lot of air through your ducts

Your ductwork here works from October through May, close to eight months a year. Every time the furnace kicks on to fight off a 24 degree night, it pushes air through the same ducts, and dust and debris ride along with it, settling in the bends and joints.

With 11% of households in New York going at least a day without power last year, and this area seeing 42 winter storms and 167 damaging wind events over the past decade, furnaces here also cycle on and off more than they would somewhere calmer. Each restart stirs up what has settled in the ducts and sends it back into the house.

How often should air ducts be cleaned?
There is no fixed schedule that fits every house. Homes with pets, a recent renovation, or someone with allergies usually need it more often than a home without those things. If you can see dust building up around the vent covers, or the air feels dusty again within a day of cleaning, that is a sign to have it looked at sooner rather than later.
Is air duct cleaning worth it?
It is worth it when there is a real reason behind it, not just as routine upkeep. Visible mold in the ducts, a rodent problem, or heavy dust after a renovation are all reasons cleaning solves something real. If the ducts look fine and no one in the house has breathing trouble, there is less to gain from it.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose the dust and debris, which the vacuum then pulls out through the vents. The supply and return registers get cleaned too, along with the coil and blower housing near the furnace or air handler, since dust collects there as well. Everything gets sealed back up once the work is finished.
