Step 1 of 3: Equipment
Six months of heating pulls a lot of air through your ducts
Your furnace runs November through April here, with winter nights averaging 38°F from December through February. That's six months of air moving through the same ductwork, carrying dust and whatever else settles in the house.
San Luis Obispo County sees wind events strong enough to knock out power, and outages here aren't rare. When a system sits off and then kicks back on, dust that settled in the ducts gets stirred up and pushed into the rooms you're heating.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes here run the heat November through April, six months of the year, so ducts get more use over the colder stretch than the warmer one. If anyone in the house has allergies, or you've had a pest problem or water damage near the ductwork, that's a reason to look sooner rather than later. A contractor can check the ducts and tell you whether cleaning makes sense now.
- Is air duct cleaning worth it?
- It depends on why you're asking. If dust is visible around the vents or you can see buildup inside the ducts, cleaning it out will cut down on what's circulating through the house. It won't lower your heating or cooling bills or fix a system that's running poorly. If the reason is comfort or air quality, it's worth doing. If the reason is efficiency, duct cleaning alone won't get you there.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to create negative pressure, then uses brushes or air tools to loosen dust and debris inside the ducts so it gets pulled into the vacuum instead of into the house. Every supply and return vent gets cleaned this way. The filter isn't part of the duct system. It sits in the path of the air and catches what's moving through it, so it usually gets checked or replaced during the same visit.
