AC Vent Cleaning in Houston, TX

Every 3 to 5 years for an average household. Sooner if anyone in the home has allergies or asthma, if you have shedding pets, if you’ve recently done remodeling work, or if a previous cleaning was more than 7 years ago. Houston specifically: high humidity drives mold growth in poorly insulated ducts, so homes with attic-routed ductwork (most of them) skew toward the shorter end of that interval.

Signs you can spot yourself: visible dust around supply registers, musty smell when the AC kicks on, increased allergy or asthma symptoms indoors, dust resettling on furniture within hours of dusting, higher-than-normal energy bills with no rate change. We run a camera up the supply trunk during inspection so you see exactly what’s in there before deciding whether cleaning is justified.

Yes, modestly. Heavy dust restricts airflow, which forces the blower to run longer and the compressor to cycle harder. After cleaning, most Houston homes see 5 to 15 percent reduction in cooling costs through summer, plus the system runs cooler and lasts longer. The bigger savings show up over time as deferred compressor failure — a $4,000+ repair we’ve seen plenty of times.

2 to 4 hours for a typical Houston single-story home. Two-story homes with multiple zones run 4 to 6 hours. We’re NADCA-trained and use negative-pressure equipment that captures debris in our truck-mounted vacuum, so soot and dust don’t end up in your living spaces. You can stay home during the work or leave us a key — either is fine.

Available as an add-on. We use EPA-registered antimicrobial fogging that kills mold spores, bacteria, and dust mites left behind after mechanical cleaning. Recommended for households with allergy sufferers, post-remediation jobs, or any home where the camera inspection turns up visible mold growth. Adds about $150 to the standard cleaning price for an average home.

$329 to $549 for an average single-story home (1 system, up to 10 vents, supply and return cleaning). $549 to $899 for two-story or two-system homes. Add $150 for antimicrobial sanitization, $200 for dryer vent cleaning bundled at the same visit, and $400 to $1,200 if a section of duct needs replacement rather than cleaning.

They can absolutely worsen existing conditions. Mold spores, dust mite waste, pet dander, and pollen accumulating in ducts get blown back into living spaces every time the AC cycles. People with asthma, allergies, COPD, or compromised immune systems are most affected. We’ve had customers report measurable symptom relief within days of a thorough cleaning, especially when sanitization is added.

Light mold growth on duct surfaces, yes — we clean and sanitize as part of the standard service. Heavier infestations or mold that’s spread into insulation or wall cavities require a different scope of work and we’ll refer you to our remediation team. Either way, we document everything with photos so you have a clear picture of what was found and what was done.
