Step 1 of 3: Equipment
Round Rock ductwork sits idle most of the year, then gets hit hard
Heat only runs here from November through March, five months out of the year. The rest of the time that ductwork sits closed up, holding whatever settled into it while the air barely moves through it.
Williamson County has seen 10 winter storms and 58 damaging wind events over the last ten years. That kind of weather knocks out power, and a third of Texas households went at least 24 hours without it in 2024. When the system sits off that long, dust and whatever else is in the air has nowhere to go but into the ducts, instead of passing through the filter.

- 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 tend to need it more often than others. If dust settles again just days after you clean house surfaces, or you can see buildup at the vent covers, that is a sign it is time. A contractor can look inside your ducts and tell you where you stand.
- Is air duct cleaning worth it?
- It is worth it when there is a real problem to fix, like visible dust blowing out of the vents, a musty smell when the air handler kicks on, or ductwork that was exposed during a renovation. It will not lower your heating or cooling bills on its own, and it will not fix an allergy that has another cause. 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 to the duct system and uses brushes or compressed air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. This covers the supply and return ducts, the grilles, and often the coil and blower compartment where dust collects. The filter gets replaced or cleaned as part of the job, since it is what keeps dust out of the ducts in the first place.
