What duct cleaning actually does for a Houston home
Houston's humidity means your ductwork collects more than dust — it holds dust mites, pet dander, mold spores, and even construction debris. A real duct cleaning runs negative-pressure agitation through every supply and return, removing the buildup so your AC circulates clean air and doesn't push contaminants through the house every cycle.
How we clean ducts, start to finish
We seal off supply registers, connect a negative-pressure vacuum to the trunk lines, and agitate each run with rotating brushes and compressed air to dislodge debris. We clean the return, the supply, and the plenum, and we inspect the coil and blower while we're in there. Most whole-home cleanings finish in 3–5 hours.
Signs your ducts need cleaning
Visible dust streaks around supply vents, a musty smell when the AC kicks on, a persistent dust film days after cleaning, worsening allergies at home, or drywall dust after a renovation. If you've had water in the ducts or a rodent problem, that's a cleaning-plus-sanitizing situation, not just a cosmetic pass.
Duct cleaning vs. duct repair
Cleaning is about removing contaminants; repair is about sealing leaks. A leaky duct system can waste 20–30% of your conditioned air into the attic. We inspect the ductwork during every cleaning and flag separated joints, collapsed flex, or return leaks so you're not paying to condition the attic.
Frequently Asked Questions
How often should ducts be cleaned in Houston?
Every 3–5 years for most homes, sooner if you have pets, allergies, recent renovation, or visible mold. Homes near the petrochemical corridor often benefit from more frequent cleaning.
Is duct cleaning worth the cost?
Yes when ducts are actually dirty — it improves air quality, reduces allergens, and helps your AC run more efficiently. A reputable company shows you before/after photos, not just a receipt.
How much does duct cleaning cost in Houston?
A whole-home cleaning typically runs $350–$650 depending on the number of returns and system size. We quote a fixed price after inspecting your system, never per-vent upsells.
Do you handle mold in ducts?
We identify mold and use EPA-registered antimicrobial treatment where appropriate. Full mold remediation on porous duct board may require replacement — we'll tell you plainly if that's the case.
