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-$850 for a full system, with most jobs scheduled within a week and completed in a single visit. The combination of year-round cooling demand and Gulf Coast humidity means Houston accumulates particulate and biological load inside ductwork roughly twice as fast as cities with a true winter off-season. Call (346) 248-1474 for a written price before any work starts.
Why Houston Homes Are Different
Houston’s subtropical Gulf Coast humidity, regularly 75-90% relative humidity year-round, paired with AC systems that run 9 to 10 months annually, creates persistent condensation inside ductwork. Flex-duct systems here become mold incubators at a rate unmatched in drier Texas metros. Hurricane Harvey in 2017 compounded this permanently: thousands of homes in ZIP codes like 77002 and 77007 had ductwork that contacted contaminated floodwater, creating sustained remediation-level demand that still differentiates Houston’s market.
The housing stock adds complexity. ZIP codes covered here span 1920s-1940s craftsman bungalows in Houston Heights, where central AC was retrofitted decades later through attics and wall cavities never designed for it, to 1970s-90s tract construction with flex-duct run through unconditioned attics. Houston is almost entirely slab-on-grade, so virtually all ductwork sits in attics that routinely exceed 140°F in summer, accelerating flex-duct liner breakdown and joint separation. In Somerset Green and Mayfair, we regularly see supply duct surfaces drop below the indoor dew point, causing condensation at flex-duct joints.
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
Full-system negative-pressure extraction of every duct run, register, and return, with a documented photo record of each line before and after. In Houston Heights, we regularly find 1920s-30s bungalows where AC was retrofitted through original plaster walls and low-pitch attic crawls, leaving ducts with sharp, unsupported bends that pool condensation and debris. Air Duct Cleaning in Houston covers our complete process for these conditions.
Dryer Vent Cleaning in Houston
Rotary brush and high-velocity air cleaning of the full vent run from dryer to termination, with airflow test before and after. Houston’s humidity means lint compacts more densely than in drier climates, and longer vent runs in newer construction around South Lawn increase restriction risk. Dryer Vent Cleaning in Houston details our approach.
Duct Repair & Sealing in Houston
Replacement of degraded flex-duct, sealing of disconnected joints with mastic and metal tape, and restoration of proper support and slope. Attic temperatures in Houston degrade duct liner faster than almost anywhere in Texas, and flood-damaged systems from 2017 still show up in 77002 and 77007. Duct Repair & Sealing in Houston explains our repair scope.

BeforeAfterHVAC Cleaning in Houston
HVAC cleaning in Houston addresses what the climate does to the entire air-handling system, not just the ducts. The near-year-round cooling season means evaporator coils, blowers, and condensers accumulate biological growth and particulate at roughly twice the rate of cities with a true winter off-season, and the 140°F attic temperatures common in Houston accelerate component fatigue. HVAC Cleaning covers our full system approach.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, reduced airflow from registers, or AC running continuously without reaching set temperature.
What it costs in Houston
Evaporator coil cleaning typically runs $250-$450 as a standalone service, or $150-$250 when bundled with full HVAC cleaning.
How we do it
We remove the coil access panel, apply foaming cleaner, rinse with low-pressure water, and photograph the coil before and after for the job record.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven airflow between rooms, or blower motor straining audibly.
What it costs in Houston
Blower cleaning typically runs $200-$350, depending on accessibility and whether the blower assembly requires full removal.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and contact cleaner, balance the wheel, and reinstall with torque to manufacturer spec.
What HVAC Cleaning Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Full HVAC cleaning (coil, blower, condenser, air handler) | $350-$850 |
| Evaporator coil cleaning (standalone) | $250-$450 |
| Blower cleaning (standalone) | $200-$350 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your ducts are clean but rooms still heat unevenly, the blower wheel or evaporator coil is likely clogged with debris the duct cleaning didn’t reach. We inspect both during every HVAC cleaning and photograph what we find before quoting.
Can HVAC cleaning fix my high summer electric bills in Houston?
A dirty evaporator coil or blower can raise energy use 15-25% by restricting airflow and extending run times. Cleaning restores designed efficiency, though it won’t fix an undersized system or leaking ductwork.
Air Quality & Sanitizing in Houston
Air quality and sanitizing in Houston targets the biological growth that Gulf Coast humidity breeds inside ductwork and air handlers. Supply duct surfaces frequently drop below the indoor dew point here, causing condensation at flex-duct joints and inside insulation wraps, fostering mold even in relatively new systems. The 2017 flood legacy in ZIP codes like 77002 and 77007 means we still encounter ductwork with residual contamination requiring treatment beyond standard cleaning. Air Quality & Sanitizing details our full protocol.
Mold Treatment
Signs you need it
Musty odor when AC cycles on, visible discoloration at register openings, or family members with unexplained respiratory symptoms.
What it costs in Houston
Mold treatment typically runs $400-$900 for a full system, depending on contamination extent and whether physical removal of degraded insulation is required.
How we do it
We apply EPA-registered antimicrobial through the full duct run, treat the evaporator coil and plenum, and verify with post-treatment photo documentation.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic musty odor, or desire for continuous biological control between service visits.
What it costs in Houston
UV light installation typically runs $300-$600 for a properly sized unit with professional mounting and electrical connection.
How we do it
We size the UV-C lamp to your air handler’s dimensions, mount it at the coil face for maximum exposure, and wire it to the blower circuit for automatic operation.
What Air Quality & Sanitizing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Full-system mold treatment | $400-$900 |
| UV light installation | $300-$600 |
| Bacteria sanitizing (whole system) | $300-$600 |
Will mold come back after treatment in Houston’s humidity?
Without moisture control, mold can return in 12-24 months; we address the source, recommend UV light for continuous suppression, and document conditions for comparison.
Is post-flood duct contamination still a problem in Houston?
Homes in 77002 and 77007 that took floodwater in 2017 still show residual contamination in flex-duct insulation; we treat with antimicrobial and replace degraded sections.

FAQs About Air Duct Cleaning in Houston
Standard duct cleaning and sanitizing do not require permits in Houston. Duct replacement or modification that alters the HVAC system’s capacity may require a permit through the City of Houston Permitting Center; we handle permit research and documentation as part of any repair scope that requires it.
Most Houston appointments are scheduled within 5-7 business days. Homes in 77002 and 77007 with post-flood contamination concerns, or systems showing active mold growth, are prioritized for earlier availability.
We provide written scope and insurance documentation for HOA submission upon request. In gated communities like Somerset Green, we coordinate access with security and observe posted work-hour restrictions.
