Fast, Reliable HVAC Cleaning Across Live Oak
Most HVAC cleaning companies in the San Antonio area treat Live Oak like any other suburb. We don’t. We’ve been driving out to the 78233 ZIP since 1984, and we know the difference between a standard tract home off Pat Booker Road and an acreage property with a detached workshop and a 14-foot overhead door. That matters because the ductwork behind those heavy-duty doors isn’t reachable with standard equipment, and the 1970s flex duct running through unconditioned attitudes out here fails differently than newer systems.
We answer calls live, 24 hours a day. Most Live Oak jobs are completed in a single visit by background-checked, uniformed technicians. If you’re near Universal City Boulevard or back toward Kirby, we’re typically on-site within the same day you call. Call (866) 347-2063 for a free estimate.
Why Bellows Air Duct & Vent Co. of Texas Is Live Oak’s Preferred HVAC Cleaning Company
Live Oak homeowners don’t call us because we’re the cheapest. They call us because they got burned by a low-bid operator once, and they want the job done right without needing to think about it again. Our reputation here is built on forty-two years of showing up when we say, presenting one honest price before we lift a single tool, and standing behind the work with our 90-Day Done Right Promise in writing.
We hear it regularly from customers in Randolph Oaks and the neighborhoods along Live Oak Road: the last company quoted one price on the phone and another at the door. That doesn’t happen with us. The number we give you is the number on the invoice. Period.
Our technicians know the local housing stock. They know the original 1978-1985 tract construction was built fast for Randolph Air Force Base families, with flex duct routed through attics that hit 140 degrees in July. They know to check for collapsed sections and torn vapor barriers before they even start cleaning, because out here, cleaning often reveals a system that needs partial replacement, not just a vacuum.
And when you call, you talk to a live person at our office, not a voicemail tree. That’s been true since 1984.
Our HVAC Cleaning Services in Live Oak
Evaporator Coil Cleaning
Live Oak’s 200-plus cooling days per year mean your evaporator coil works nearly nonstop. In the 1970s and 1980s systems common off Nacogdoches Road and Judson Road, those coils sit in air handlers mounted in hot attics, collecting a paste of dust, pollen, and microbial growth that standard filters never catch. A dirty coil can drop your system’s efficiency by 30% and freeze up entirely during peak summer demand. We clean coils with professional-grade foaming agents and low-pressure rinses, then verify the results with our camera inspection. Most evaporator coil cleanings in Live Oak run $180-$320.

Heat Exchanger Cleaning
Gas furnaces in older Live Oak homes still need safe, thorough heat exchanger inspection and cleaning before winter. Cracked or corroded exchangers are a genuine safety hazard, carbon monoxide risk, and not something to guess at. Our technicians use borescope cameras to inspect every inch, then clean with Nikro-powered HEPA vacuums and soft-bristle tools that won’t damage aging metal. If we find a crack, we tell you plainly and document it. Heat exchanger cleaning and inspection in Live Oak typically costs $220-$380.

Condenser Cleaning
Your outdoor condenser coil is exposed to everything the northeast San Antonio corridor throws at it: limestone dust, cottonwood fluff in spring, and the fine yellow coating of mountain cedar pollen from December through February. A clogged condenser can’t reject heat efficiently, so your system runs longer, costs more, and wears out faster. We pull the fan assembly, clean coils from the inside out with foaming cleaner and low-pressure water, and check refrigerant levels while we’re there. Condenser cleaning in Live Oak generally runs $150-$280.

Blower Cleaning
The blower assembly is the engine of your airflow. In Live Oak’s older systems, blowers often run with unbalanced or dirty wheels, drawing more amperage and delivering weaker air to rooms farthest from the air handler. We remove the blower housing, clean the wheel and housing with Rotobrush agitation and HEPA extraction, and rebalance if needed. This is especially important in the long duct runs typical of acreage properties, where every CFM counts. Blower cleaning in Live Oak usually costs $160-$290.

Air Handler Cleaning
The full air handler cabinet, drain pan, and associated components need periodic cleaning to prevent mold colonization and musty odors. In Live Oak’s humid subtropical climate, standing water in a dirty drain pan becomes a breeding ground within days. We clean and treat the entire cabinet, clear drain lines, and apply EPA-registered antimicrobial where appropriate. Full air handler cleaning runs $200-$350 in this market.

Coil Treatment
After cleaning, we offer optional coil treatment with professional-grade products that inhibit future microbial growth without leaving a residue that restricts airflow. This is popular with Live Oak customers who struggle with allergy symptoms during cedar fever season, as it reduces the biological load circulating through the home. Coil treatment adds $45-$85 to any cleaning service.

Trusted Brands We Service in Live Oak
We carry professional-grade equipment from Rotobrush, Nikro, and Honeywell, the same brands serious HVAC contractors specify for commercial jobs. For Live Oak customers, that means we stock the right brushes, whips, and vacuum attachments for older duct geometries, not just the standard kits that work in new construction. When we find a Lennox, Carrier, or Trane unit that needs coil cleaning or a blower pulled, we’ve got the tools and the parts knowledge to finish in one trip. No waiting on a parts run to San Antonio. No second appointment. That’s the point of a one-trip service.
Common HVAC Cleaning Problems We See in Live Oak Homes
- Collapsed flex duct in detached workshops. The acreage properties common in Live Oak often have detached shops with 14-foot overhead doors and heavy-duty openers, with flex duct run through unconditioned attic spaces above. After forty years of thermal cycling, that duct has often collapsed or torn at the vapor barrier, blocking airflow entirely. Standard cleaning equipment can’t even reach these runs.
- Cedar pollen reservoirs in aging fiberglass-lined duct. The December-February mountain cedar bloom produces extreme airborne pollen counts in the 78233 area. Older fiberglass-lined duct acts like a filter that never gets changed, recirculating allergen loads long after outdoor counts drop. Cleaning without HEPA containment just redistributes it.
- DIY cleaning missing the real problem. Self-reliant Live Oak homeowners often rent consumer-grade equipment and clean what they can reach, missing the collapsed sections, mold in the plenum, or degraded liner that a professional Rotobrush inspection with camera verification would catch immediately.
- Multiple callbacks from split-trip services. Most cleaners do one visit for diagnosis, order parts, and return later. In Live Oak’s aging housing stock, we find that cleaning nearly always reveals replacement needs. Our one-trip approach, with a fully stocked truck and technicians trained to clean and repair, eliminates that second drive out to your acreage property.

FAQs - HVAC Cleaning in Live Oak
Schedule your HVAC cleaning in late October or early November, before the December-February cedar bloom peaks. The 78233 area sits directly downwind of the Hill Country cedar belt, and extreme pollen counts during this period load your duct system with allergen reservoirs that recirculate for months. If you’ve already missed that window, mid-March cleaning clears the buildup before summer AC season begins. Call (866) 347-2063 to book - estimates are free.
Yes, especially if that workshop has conditioned air supplied from your main system. The long flex duct runs to detached structures in Live Oak acreage properties are prone to collapse and vapor barrier tears from decades of attic heat cycling, and they’re rarely reachable with consumer equipment. Our heavy-duty Rotobrush system and extended reach tools handle these runs, and our camera inspection shows you exactly what we found. Call (866) 347-2063 for a free estimate.
Cleaning might help, but poor airflow in Live Oak’s older systems usually signals collapsed duct sections, torn vapor barriers, or degraded fiberglass liner, not just surface debris. We camera-inspect before we clean, so you’ll know whether the issue is buildup or structural failure before we start. If it’s structural, we can often repair or replace the damaged sections in the same visit. Call (866) 347-2063 and we’ll diagnose it properly.
Yes. The Lennox G-series and early Merit systems installed in Live Oak’s 1970s-1980s construction are familiar territory for our technicians. We use foaming cleaners formulated for older aluminum and copper coils, low-pressure rinse methods that won’t damage fin integrity, and camera verification to confirm results. Coil cleaning on these units in Live Oak typically runs $180-$320. Call (866) 347-2063 to schedule.
Acreage properties in Live Oak have longer driveways, gated access, and often detached structures that require specialized equipment. A two-trip service means two navigation events, two gate codes, two schedule blocks, and twice the disruption to your day. Our technicians arrive with Rotobrush heavy-duty vacuums, repair materials, and the training to clean and replace in a single visit. That’s not convenience. That’s respecting your time. Call (866) 347-2063 to book.
