Your ductwork works eight months a year here
Furnaces around Crystal Lake run from October through May, and every one of those months pushes air through the same ducts. Dust, pet hair, and the fine grit that comes in on shoes and clothes settle into that ductwork over a heating season this long, and it builds up on the inside of the runs where nothing scrubs it loose.
Winter nights here average 17°F, so the system is on often, moving that settled dust back into the house each time it runs. Dirty ducts also make a furnace work harder to push air through the same trunk lines, and that strain shows up on the parts that keep the house warm on the coldest nights.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor will look at your system before giving you a number. If anyone in the house has allergies, or you have pets shedding into the return vents, that pushes you toward cleaning sooner rather than later. If you've had a furnace swap or a remodel that opened up the ducts, have them cleaned after, so the debris from that job doesn't blow right back into the rooms.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like dust that keeps coming back no matter how often you clean, a musty smell when the furnace kicks on, or visible debris around the vent covers. It won't lower your heating bills or fix a furnace that's struggling. Think of it as a cleaning job, not a repair.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to pull it under negative pressure, then runs brushes or air whips through each run to knock loose dust and debris so the vacuum can pull it out. They pull the vent covers and registers first to get access, and go through the return side as well as the supply side. The furnace blower and coil usually get cleaned in the same visit, since that's the part of the system moving the air through everything else.
