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 whole-system job, with air quality and sanitizing services adding $200-$450 depending on whether mold treatment or UV installation is needed. The city’s near-year-round air conditioning and sustained humidity above 75% create conditions that accelerate coil fouling and microbial growth inside duct systems. We coordinate dispatch and scheduling from our Houston office, and crews serve neighborhoods across the metro with background-checked, uniformed technicians operating under the H.A.V.E.N. Standard. Call (346) 423-3631 for a written estimate before any work begins.
Why Houston Homes Are Different
Houston’s Gulf Coast climate means dew points regularly sit above 75°F, among the highest in the continental U.S. Any breach in a duct’s vapor barrier inside a hot attic creates immediate condensation, and oversized or short-cycling systems leave surfaces wet long enough for mold to colonize within days.
The housing stock compounds this. Suburban buildouts from the late 1970s through the 2000s in Katy, Pearland, Sugar Land, Clear Lake, and Friendswood produced slab-foundation tracts with flex duct routed through unconditioned attics that hit 140°F+ in summer. These runs sag, disconnect at collars, and accumulate debris at low points. Older bungalows inside the Loop, in The Heights, Montrose, and Eastwood, had HVAC retrofitted into structures never designed for ductwork, yielding convoluted, poorly sealed runs.
In Meyerland, Braeswood, and along Brays Bayou, crews still find Hurricane Harvey sediment and mold entrenched in ductwork years after 2017. Homeowners dried floors and drywall but never addressed attic or under-slab sections that wicked floodwater. This is a known failure pattern specific to Houston’s most repeatedly flooded zip codes.
Our Main Houston Services
Homeowners across Houston call us most often for these three services, each with its own dedicated page and local pricing.
Air Duct Cleaning in Houston
Full-system cleaning of supply and return ductwork, registers, and the plenum, the central distribution box, using negative-pressure extraction and rotary brush systems. In Houston, we pay particular attention to flex duct low points where humidity-driven debris collects, and we document every run with before-and-after photos. Air Duct Cleaning in Houston
Dryer Vent Cleaning in Houston
Lint removal from the full vent run, from back of dryer to exterior termination, with airflow testing before and after. Houston’s humidity causes lint to clump and adhere to vent walls more aggressively than in drier climates, and longer vent runs common in newer suburban builds increase restriction risk. Dryer Vent Cleaning in Houston
Duct Repair & Sealing in Houston
Reconnection of separated flex duct collars, sealing of plenum leaks, and replacement of degraded vapor barriers in attic runs. Houston’s thermal expansion cycles, 140°F attic summers to 40°F winter nights, degrade tape and mastic bonds faster than in moderate climates. Duct Repair & Sealing in Houston

BeforeAfterHVAC Cleaning in Houston
Houston’s 9-10 month cooling season and sustained humidity above 75% mean evaporator coils and blower assemblies foul faster here than in any major Texas metro. Systems run almost continuously from March through November, and the combination of moisture and organic debris creates biofilm on coil fins that restricts airflow and drives up energy use. Our HVAC Cleaning service addresses this with documented, component-level work that includes photo records of every stage.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or a musty odor when the AC cycles on indicate coil fouling.
What it costs in Houston
Evaporator coil cleaning in Houston typically runs $180-$320 for accessible A-coils in attic air handlers.
How we do it
We remove the access panel, apply foaming cleaner to the coil face and fins, rinse with low-pressure water to avoid fin damage, and photograph the assembly before and after reassembly.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust puffing from registers on startup point to blower wheel imbalance or buildup.
What it costs in Houston
Blower wheel and housing cleaning in Houston generally ranges $150-$280.
How we do it
We remove the blower assembly, clean the wheel blades and housing with compressed air and solvent, balance the wheel on its shaft, and reinstall with torque-checked hardware.
What HVAC Cleaning Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + housing) | $350-$650 |
How do I know my HVAC needs cleaning versus just my ducts?
If you have weak airflow, musty odors, or ice on refrigerant lines after duct cleaning, the problem is likely in the coil or blower, not the duct runs themselves. Call (346) 423-3631 and we’ll inspect both systems and put a written price to each option.
Can HVAC cleaning reduce my summer electric bill in Houston?
A fouled coil can raise energy consumption 15-30% by forcing longer run times to reach setpoint; cleaning restores designed airflow and heat transfer. We measure static pressure before and after so you have documented evidence of improvement.
Air Quality & Sanitizing in Houston
Houston’s humidity-driven mold problem makes air quality work less optional than in drier markets. When moisture infiltrates flex duct joints in unconditioned attics, mold colonies feed on organic debris and cycle through living spaces with every system run. Our Air Quality & Sanitizing service targets this with treatments applied after mechanical cleaning, with photo documentation of affected areas and written scope before any work begins.
Mold Treatment
Signs you need it
Visible black or green growth on register fins, persistent musty odor that returns after duct cleaning, or allergy symptoms that worsen when the system runs.
What it costs in Houston
Mold treatment for affected duct runs in Houston typically runs $250-$450 per system, depending on extent and accessibility.
How we do it
We apply EPA-registered antimicrobial through the duct system at proper dwell time, treat the plenum and accessible trunk lines, and photograph all treated surfaces for the job record.
UV Light Installation
Signs you need it
Repeated mold recurrence after treatment, or a home in a high-humidity zone like Meyerland or Braeswood with chronic moisture intrusion.
What it costs in Houston
UV-C lamp installation at the coil or plenum in Houston generally ranges $300-$550 including hardware and electrical connection.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp at the coil face or upstream plenum, wire to the air handler’s 24V circuit, and verify irradiance with a meter before closing the panel.
What Air Quality & Sanitizing Costs in Houston
| Item | Typical range in Houston |
|---|---|
| Mold treatment (per system) | $250-$450 |
| UV light installation | $300-$550 |
| Bacteria sanitizing (whole system) | $200-$350 |
Does UV light actually prevent mold in Houston’s humidity?
UV-C at the coil surface prevents biofilm formation by breaking DNA bonds in mold spores and bacteria; it does not dehumidify, so source moisture must still be addressed. We install Honeywell and Aprilaire units with documented irradiance levels and include the lamp in your annual service reminder.
Is mold treatment safe for my family and pets?
We use EPA-registered, low-toxicity antimicrobials applied at manufacturer-specified dilution and dwell time, with the system off during treatment and flushed before restart; we leave the SDS and application record with your job documentation.

FAQs About Air Duct Cleaning in Houston
Standard residential duct cleaning and HVAC component cleaning do not require permits in Houston. Duct repair or replacement that involves modifying the plenum or changing system capacity may trigger a permit under city mechanical code; we handle permit research and documentation as part of any repair scope if needed.
Most Houston appointments are available within 3-5 business days, with some next-day openings depending on route density. July through August see the highest demand due to humidity-driven service calls; we recommend booking ahead during those months.
We service all residential types in Houston, including high-rise condos in the Galleria and Midtown areas where access requires coordination with building management. We carry certificate of insurance documentation for HOA and building requirements, and we schedule around building access windows when needed.
