Conroe ductwork sits idle most of the year, then gets pushed hard
Your furnace only has to run November through March here, about five months, on nights that average 43°F. The rest of the year the same ducts carry cooled air instead. That long stretch of mild weather in between, with the system barely running, gives dust plenty of time to settle in the duct runs before the furnace or the AC calls for air again.
Montgomery County has logged 4 winter storms and 72 damaging wind events over the past ten years, and across Texas a third of households lost power for 24 hours or more in 2024. When power drops and a system sits off, then comes back on, the air that finally moves through the ducts pushes out whatever settled while things were quiet. With most homes here owner-occupied, that buildup is something the same household lives with year after year, not something a new tenant resets.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor should look at the ductwork itself before you decide. Homes with pets, a smoker, or someone with allergies tend to need it more often than others. If dust comes back within days of a cleaning, or you've had duct work or a renovation done recently, that's a sign to have it checked sooner rather than waiting.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust buildup, a musty smell from the vents, or leftover debris from recent duct work. It won't lower your energy bills or fix an allergy on its own, since ducts move air rather than clean it. The filter is what actually cleans the air passing through, so a clean filter matters as much as clean ducts.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris as they go, then pulls it out through the vacuum before it resettles. They'll also check the supply and return vents and the coil, since dust collects there too. A full job covers the whole system, not just a few vents, since air moves through all of it.
