Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning in Houston, TX
HVAC cleaning in Houston typically runs $350-$650 for a complete system, and every job starts with a written price before we touch a single panel. Houston’s Gulf Coast humidity and 10-month cooling season create conditions we don’t see in Dallas or Austin: flex ductwork in 150°F attics breeds mold and biofilm at rates that demand more frequent, more thorough cleaning. We dispatch from our Houston office, and crews serve homeowners across the metro with Rotobrush and Abatement Technologies equipment. Call (346) 253-1822 for a free estimate.
Why Houston Homes Are Different
Houston’s oil-boom suburban expansion from the 1960s through the 1990s filled Katy, Pearland, and the northwest loop with slab-on-grade ranch and two-story homes, almost all built with flex duct systems in unconditioned attics. The city’s lack of zoning meant one block might hold a 1972 ranch with original ductwork beside a 1998 build with fiberglass board plenums - the distribution box that feeds each duct run - and both face the same enemy.
Average relative humidity here exceeds 70-75% year-round. When Houston’s expansive clay soils shift foundations and pull duct connections apart, the temperature gap between 150°F attic air and cold supply air drives condensation at every joint. That moisture, inside dark ductwork, creates ideal mold-growth conditions. In Meyerland, Kingwood, and parts of the Energy Corridor, post-Harvey rebuild crews replaced drywall but left original ductwork untouched; we regularly find active mold colonies inside systems surrounded by fresh paint and new floors.
Our Main Houston Services
Homeowners in Houston call us most often for these three services, each with its own dedicated Houston page.
Air Duct Cleaning in Houston
We clean the full supply and return network - every duct run, the plenum, and each register - using negative-pressure extraction with Rotobrush contact cleaning. In Houston, we pay particular attention to water-stained flex duct from prior floods and separation points where clay-soil foundation movement has pulled joints apart. Air Duct Cleaning in Houston covers our full process and what we document on every visit.
Dryer Vent Cleaning in Houston
Lint accumulation in dryer vents accelerates in Houston’s humidity, and the longer vent runs common in two-story Energy Corridor and Cinco Ranch homes increase blockage risk. We clear the full vent path from appliance to termination, photograph the before-and-after condition, and verify airflow with a meter reading. Dryer Vent Cleaning in Houston has full details.
Duct Repair & Sealing in Houston
Foundation shift on Houston’s gumbo clay separates duct joints and tears flex duct at plenum connections. We repair or replace damaged sections, seal joints with mastic - the brush-applied sealant that outlasts tape - and pressure-test the system to verify no leaks remain. Duct Repair & Sealing in Houston explains our repair scope and documentation.

BeforeAfterHVAC Cleaning in Houston
Complete HVAC cleaning in Houston addresses the components air passes through after it leaves your ducts: the evaporator coil, blower assembly, condenser, and air handler. Houston’s 10-month cooling season means these components run harder and longer than inland Texas systems, and the humidity load forces coils to shed more condensate - the water that drips to your drain line - which can breed algae and biofilm that restricts airflow and drives up energy use. HVAC Cleaning covers our full equipment and process standards.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or a musty smell when the AC first cycles on.
What it costs in Houston
Evaporator coil cleaning typically runs $180-$320 in Houston.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition for your job record.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across rooms, or dust blowing from registers immediately after filter changes.
What it costs in Houston
Blower assembly cleaning typically runs $150-$280 in Houston.
How we do it
We remove the blower motor and wheel, clean each blade and the housing with compressed air and solvent, balance the wheel, and reinstall with torque-verified fasteners.
What HVAC Cleaning Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $150-$280 |
| Condenser coil cleaning | $120-$220 |
How often should HVAC cleaning be done in Houston?
Every 2-3 years for typical Houston homes, but annually if you have pets, recent water intrusion, or run the system continuously through summer. Call (346) 253-1822 and we’ll assess your specific system.
Can HVAC cleaning lower my electric bill?
Yes - a clean evaporator coil and blower move air more efficiently, which can reduce runtime and energy use, especially during Houston’s six-month peak cooling period.
Air Quality & Sanitizing in Houston
Air quality and sanitizing in Houston targets the microbial growth that Gulf Coast humidity breeds inside ductwork and on HVAC components. Post-Harvey neighborhoods remain a particular concern: we find active mold in duct systems whose surrounding walls were fully rebuilt, because remediation crews addressed visible damage but not the hidden cavities above ceilings. Our process treats the source, not the symptom, with documented before-and-after verification on every job. Air Quality & Sanitizing details our full treatment protocols.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible discoloration at registers, or recent water intrusion even if drywall was replaced.
What it costs in Houston
Whole-system mold treatment typically runs $400-$750 in Houston.
How we do it
We apply EPA-registered antimicrobial through the full duct network, treat the plenum and coil with contact spray, and deliver dated photos of every treated surface.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, allergy symptoms that worsen when the system runs, or a home in a high-humidity flood-prone zone.
What it costs in Houston
UV-C light installation typically runs $350-$600 in Houston.
How we do it
We mount a UV-C lamp in the supply plenum - the distribution box where treated air enters the duct runs - wire to the blower circuit for automatic operation, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Whole-system mold treatment | $400-$750 |
| UV-C light installation | $350-$600 |
| Bacteria sanitizing (per system) | $250-$450 |
Does sanitizing kill mold in Houston ducts?
Our treatment kills active mold and applies a residual inhibitor, but it cannot restore physically degraded flex duct; we photograph the condition and note if replacement is needed.
Is UV light worth it in Houston’s humidity?
For homes with chronic mold recurrence or in flood-prone areas, yes - continuous UV-C irradiation at the coil and plenum suppresses growth between professional cleanings.
Brands We Service in Houston
We stock parts and service equipment from Honeywell, Aprilaire, and Guardsman, with most replacement components available for Houston jobs without ordering delays. Our brands page lists full compatibility.
