Seven months of heating means seven months through the same ducts

Your furnace runs from October through April here, seven months of the year. On winter nights averaging 27°F, it cycles on and off all night to keep up. Each cycle pushes air through the same ductwork, and dust settles along the way with that much use.

Spotsylvania County has had 9 winter storms and 149 damaging wind events over the past ten years. Power loss during storms like these stops a furnace mid-cycle and starts it again once power is back, and that stopping and starting adds to what collects inside the ducts over time.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. A house with pets, a recent renovation, or someone with allergies may need it sooner than one without. If you see dust building up around the vent covers or the air feels dusty again within a day of cleaning, that is a sign to move the schedule up. A contractor can look at your ducts and tell you where you stand.
Is air duct cleaning worth it?
It is worth it when there is a real reason behind it, like visible dust, a musty smell from the vents, or work done on the ductwork itself. It will not lower your heating bills, and it will not fix an allergy on its own. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls, then pulls it out through the vacuum. The supply and return vents, the main trunk lines, and sometimes the coil and blower housing get cleaned in the process. Vents get sealed off room by room as the work moves through the house, so the suction stays strong through the whole system.
