Call (844) 685-6342 for a free estimate - the price we quote is the price on the invoice.
We’ve been driving out to Austin from our Los Angeles headquarters for years, and we know the territory. Central Texas attics hit 140-160°F by June, causing flex-duct linings to delaminate and joints to separate, which pulls 150°F attic air and fiberglass particles directly into the supply stream - a failure mode absent in milder climates. Our HVAC Cleaning team has replaced collapsed duct sections in homes from East 12th Street to Wells Branch, and we bring the equipment to finish the job in one trip, even on rural properties with long service drives.
Why Bellows Air Duct & Vent Co. Is Austin’s Preferred HVAC Cleaning Company
Ray Castillo founded Bellows Air Duct & Vent Co. in 1984, and the 90-Day Done Right Promise we stamp on every job has stayed non-negotiable for over 42 years. If the work is not right, we return at no charge with no paperwork required. That promise travels with us to Austin, where homeowners who have lived through one Cedar Fever season know the value of a company that stands behind its word.
Our technicians are background-checked and uniformed on every job, and they carry camera inspection equipment to document duct conditions before and after cleaning. We do not bait-switch with coupon pricing - your upfront quote matches your final invoice. Calls are answered by a live person, 24/7, not a voicemail tree.
We know Austin’s housing stock. The 1950s-1970s ranch homes in ZIP codes like 78702 and 78722 often contain original flex duct or early sheet-metal systems that have never been serviced. The post-2000 tract homes across the outer east and northeast sides have attic-run flex duct that degrades rapidly in that extreme attic heat. We have cleaned both, and we know what to look for before we lift a tool.
Our HVAC Cleaning Services in Austin
Evaporator Coil Cleaning
Austin’s humidity spikes during spring and fall create condensation risk inside ductwork on oversized AC systems, a common installation problem in the rapid-growth construction of the 1990s-2000s suburbs. We remove the coil and clean it with pressurized foaming agents, then inspect the drain pan for standing water or algae buildup. Skipping this step is why mold recurs within 90 days in so many Austin homes. Our $89 Seasonal Tune-Up includes a visual coil inspection.
Blower Cleaning
The blower motor and wheel collect the same cedar pollen and construction dust that circulates through Austin ducts. A dirty blower drops airflow by 15-30% and forces your system to run longer in those 100°F July afternoons. We remove the blower assembly, clean the wheel vanes and motor housing, and re-balance the assembly before reinstall. Most blower cleanings in Austin run $180-$290 as part of a larger system service.
Condenser Cleaning
Outdoor condenser coils in Austin fight a constant battle with cottonwood fluff, cedar pollen, and limestone dust. We fin-comb the coils, apply foaming cleaner, and flush with low-pressure water - never high-pressure, which folds the aluminum fins and traps debris deeper. A clean condenser can lower your summer electric bill by 10-15% in Central Texas heat. Condenser cleaning alone typically costs $120-$195 in the Austin market.
Air Handler Cleaning
The air handler is the central station of your system, and in Austin’s older homes it often sits in a 160°F attic that has baked the internal insulation and loosened every joint. We clean the cabinet, replace degraded insulation where accessible, and seal joints with mastic - not duct tape, which fails in that heat. Full air handler cleaning with joint sealing runs $240-$380 in Austin.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Austin’s older ranch homes - many original to the 1960s and 1970s - crack or corrode from decades of thermal cycling. We visually inspect and clean the exchanger surfaces, checking for carbon monoxide leakage paths. This is not a step to skip on a 40-year-old system. Heat exchanger inspection and cleaning as part of a full HVAC service runs $200-$340.
Coil Treatment
Unmatched coil treatments after cedar-pollen season leave a biofilm that re-contaminates ducts within weeks. We always follow evaporator coil cleaning with an EPA-registered antimicrobial coil treatment using Abatement Technologies products. This treatment inhibits mold and bacterial growth through Austin’s humid shoulder seasons. Coil treatment adds $85-$140 to a coil cleaning service.

Trusted Brands We Service in Austin
We carry professional-grade equipment from Rotobrush, Abatement Technologies, and Aprilaire - the same brands serious HVAC contractors specify for commercial installations. Our trucks stock replacement parts for these systems so we’re not waiting on a warehouse run while your attic hits 150°F. For Austin customers, that means same-day completion on most jobs, not a return visit next week. We also source Guardsman-treated components where specified for high-humidity applications.
Common HVAC Cleaning Problems We See in Austin Homes
- Delaminated flex duct in 140°F attics. Austin attics routinely hit 140-160°F in summer, accelerating the breakdown of flex duct lining and causing joints to separate. This draws unconditioned attic air and insulation particles directly into your supply stream. We replace degraded sections with high-temp-rated rigid duct and seal with mastic.
- Cedar pollen biofilm on evaporator coils. The December-February Cedar Fever season releases pollen fine enough to bypass standard 1-inch filters and cake duct interiors. By March, this pollen has formed a sticky biofilm on coils that standard cleaning misses. We follow mechanical cleaning with antimicrobial treatment to prevent rapid recontamination.
- Collapsed flex duct in flipped homes. Central Austin’s teardown-and-renovation wave means technicians frequently encounter decades of construction debris, rodent intrusion, and collapsed flex duct inside walls of homes being flipped. We camera-inspect before cleaning to identify these hidden failures.
- Oversized AC systems with condensation problems. The 1990s-2000s suburban boom installed many oversized units that short-cycle and leave moisture on coils and in drain pans. We clean the coils, treat the pans, and check for proper drainage - skipping this guarantees mold recurrence within 90 days.

FAQs - HVAC Cleaning in Austin
Cedar Fever releases pollen fine enough to bypass standard 1-inch filters and form a sticky biofilm on duct interiors and evaporator coils. We recommend scheduling HVAC cleaning in February or March, after the first hard rain ends the season, to remove this buildup before it recirculates. Call (844) 685-6342 to book - estimates are free.
Yes. We use lower-pressure Rotobrush cyclone cleaning and soft-bristle attachments on aged sheet-metal systems, and we camera-inspect joints for rust or separation before applying any mechanical force. Many homes in 78702 and 78722 have this original ductwork, and we have cleaned hundreds without damage. Call (844) 685-6342 for an assessment.
We send a single truck with a 200-foot hose reel and dual-motor Rotobrush unit, so we can reach detached workshops and outbuildings without a second trip or second crew. This saves you the travel-time charges that other companies add for rural properties. Call (844) 685-6342 to discuss your layout.
In Austin, this usually means a separated flex-duct joint in a 140-160°F attic is pulling unconditioned attic air into your supply stream. In a 1970s ranch on East 12th Street in 78702, we found a collapsed flex-duct joint that had been dumping 150°F attic air and decades of fiberglass insulation dust into the master bedroom register. We replaced the section with a high-temp-rated rigid duct and sealed all accessible joints with mastic, then cleaned the entire system with a Rotobrush cyclone unit - eliminating the 20°F temperature rise at that register. Call (844) 685-6342 if your registers feel warm.
Yes. We apply EPA-registered antimicrobial treatments in compliance with Texas regulations, using Abatement Technologies products specified for HVAC applications. This treatment is included in our coil service or available as an add-on. Call (844) 685-6342 to schedule.
