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.

Why Alvin Homes Are Different
Alvin sits in one of the wettest spots in the continental United States, holding the record for the highest 24-hour rainfall total in U.S. history at 43 inches from Tropical Storm Claudette in 1979. That moisture history matters because Alvin ductwork faces mold and microbial contamination as the primary threat, not ordinary dust accumulation.
The housing stock tells the same story. Older core neighborhoods feature 1960s-1980s ranch-style homes with original flex-duct systems run through attics that exceed 150°F in summer. That heat degrades duct liner and accelerates condensation buildup. Post-Harvey construction added newer stock, but many rebuilt homes had ductwork exposed to standing water, leaving dried sediment and microbial colonies standard cleaning must address.
Homes near Mustang Bayou and Chocolate Bayou corridors need particular attention. Techs regularly find a distinctive silty residue line inside lower duct runs from Harvey backflow, dried and become a substrate for mold that visual inspections routinely miss.
Our Main Alvin Services
Alvin homeowners call us most often for these three services, each with its own dedicated Alvin page.
Air Duct Cleaning in Alvin
Whole-system negative-pressure extraction for homes with flex-duct, hard-pipe, or hybrid systems. In Alvin, we pay special attention to moisture-damaged liner and post-flood sediment that standard brush-and-vac methods leave behind. Every run is photographed before and after. Air Duct Cleaning in Alvin
Dryer Vent Cleaning in Alvin
Lint removal from dryer exhaust runs through attics and exterior walls, common in Alvin’s ranch-style homes with long vent paths. Gulf Coast humidity causes lint to mat and adhere, increasing fire risk and drying time. We verify airflow at termination with a manometer. Dryer Vent Cleaning in Alvin
Duct Repair & Sealing in Alvin
Repair of disconnected runs, degraded flex-duct, and failed mastic seals in attics that cycle between 150°F summer heat and winter cold. Post-Harvey homes often need partial replacement of flood-exposed sections. Sealing is verified with pressure testing. Duct Repair & Sealing in Alvin

BeforeAfterHVAC Cleaning in Alvin
HVAC cleaning in Alvin addresses what Gulf Coast humidity and near-constant system runtime create: evaporator coils that grow mold in as little as two seasons, blower wheels caked with adhesive dust, and condensate pans that harbor bacteria. We clean the components your ductwork connects to, because dirty equipment re-contaminates clean ducts immediately. HVAC Cleaning covers our full process for every component type.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odor when the AC first cycles on.
What it costs in Alvin
Evaporator coil cleaning typically runs $280-$420 in Alvin, depending on accessibility and contamination level.
How we do it
We remove the coil if accessible, apply foaming cleaner, rinse with low-pressure water, and photograph the fins before and after.
Blower Cleaning
Signs you need it
Uneven heating or cooling between rooms, higher electric bills, or visible dust puffing from registers at startup.
What it costs in Alvin
Blower cleaning typically runs $240-$380 in Alvin, with additional cost if the motor requires removal.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and solvent, balance the wheel, and document RPM and amp draw.
What HVAC Cleaning Costs in Alvin
| Item | Typical range in Alvin |
|---|---|
| Evaporator coil cleaning | $280-$420 |
| Blower cleaning | $240-$380 |
| Full HVAC system cleaning (coil + blower + pan) | $520-$740 |
How do I know my HVAC components are actually dirty?
We photograph every component before touching it, and the photo is yours before we quote. If the coil shows no mold or the blower wheel spins clean, we’ll tell you and charge nothing for the inspection.
Can HVAC cleaning fix my musty smell?
Yes, if the odor originates in the coil, pan, or blower. If the ductwork itself harbors mold, we recommend adding air quality sanitizing to the scope.
Air Quality & Sanitizing in Alvin
Air quality sanitizing in Alvin targets the mold spores and bacteria that thrive in ductwork exposed to Gulf Coast humidity and flood history. We treat the biological contamination that mechanical cleaning alone cannot eliminate, using EPA-registered products applied with controlled droplet size to reach the full duct perimeter. Air Quality & Sanitizing details our full protocol.
Mold Treatment
Signs you need it
Visible mold at registers, musty odor that returns within days of cleaning, or occupants with worsening allergy symptoms indoors.
What it costs in Alvin
Mold treatment typically runs $380-$620 in Alvin, depending on system size and contamination extent.
How we do it
We apply an EPA-registered fungistat with a fogging wand at each register, allow dwell time, then extract residual with negative pressure.
UV Light Installation
Signs you need it
Repeated mold recurrence after treatment, or a coil that requires annual cleaning due to persistent biological growth.
What it costs in Alvin
UV light installation typically runs $340-$560 in Alvin, including the lamp, housing, and electrical connection.
How we do it
We mount a UV-C lamp with sight glass in the supply plenum, wire to the air handler’s 24V circuit, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Alvin
| Item | Typical range in Alvin |
|---|---|
| Mold treatment (whole system) | $380-$620 |
| UV light installation | $340-$560 |
| Combined mold treatment + UV install | $640-$980 |
Is the sanitizing product safe for my family?
We use EPA-registered products with no residual toxicity at application strength, and we ventilate the system for 30 minutes post-treatment before occupants re-enter.
Will mold come back after treatment?
Without fixing the moisture source, yes. We identify and document the source, and UV installation at the coil prevents recurrence in most Alvin homes.

What Alvin Customers Say

- Petra K."The before and after photographs of each run are the reason I used them. You cannot argue with what came out of the return."
- Marguerite O."They found a disconnected duct in the crawl space that had been dumping conditioned air under the house for years. Photographed it, quoted the repair, fixed it."
