We’re familiar with the full stretch of Boerne, from the historic stone cottages along Main Street in 78006 to the newer master-planned communities off Interstate 10 in 78015. Our technicians are background-checked, uniformed, and carry the same professional-grade equipment we use in Los Angeles - Nikro negative air machines, Rotobrush contact cleaning systems, and Honeywell air quality monitors. Most Boerne calls reach us within the hour, and we schedule same-day or next-day service because we know a non-working AC in July isn’t something you wait on.
Why Bellows Air Duct & Vent Co. Is Boerne’s Preferred HVAC Cleaning Company
We’ve built our reputation in Boerne on one principle: the job is done right, or we make it right. No paperwork, no arguing. Our 90-Day Done Right Promise is stamped on every invoice, and it’s the reason homeowners in Esperanza, Mirror Oak, and the older 78006 corridor call us back when they need service again.
Boerne customers tell us they chose us after a bad experience with a low-bid operator who changed the price at the door or left without showing what was actually cleaned. We don’t work that way. Every job gets a camera inspection before and after - a visual record you can see, not just a claim on a checklist. Our pricing is disclosed upfront before a single tool is lifted. The number on the phone is the number on the invoice.
Calls to our office are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. When you call (844) 685-6342, you talk to someone who can schedule your Boerne appointment and answer your questions.
Our HVAC Cleaning Services in Boerne
Evaporator Coil Cleaning
The evaporator coil is where your AC system does its hardest work, and in Boerne it works overtime. From May through October, heavy runtime on the Balcones Escarpment means coils collect a stubborn layer of Hill Country limestone dust mixed with cedar pollen that standard filter changes never catch. A dirty coil can’t transfer heat efficiently. Your system runs longer, your bills climb, and the coil becomes a breeding ground for mold in Boerne’s humid summer peaks. We clean coils with foaming agents and low-pressure rinses that restore efficiency without damaging delicate fins. Most Boerne evaporator coil cleanings run $180-$320.
Blower Cleaning
The blower fan pushes every cubic foot of air through your home, and when it’s coated in dust, airflow drops across every room. In Boerne’s newer 78015 subdivisions, we’ve found blower assemblies caked with the same fine white caliche dust that clogs filter housings within weeks of move-in. Our technicians remove the blower housing, clean the wheel and motor assembly, and re-balance the unit for proper operation. A clean blower means even temperatures, quieter operation, and less strain on the motor. Typical blower cleaning in Boerne: $150-$275.
Condenser Cleaning
Your outdoor condenser coil faces the full brunt of Boerne’s Hill Country environment - cottonwood fluff in spring, limestone dust year-round, and the debris from those intense short-burst rainstorms that blow leaves and grit into the fins. A clogged condenser can’t release heat. The compressor works harder, draws more amperage, and fails prematurely. We clean condenser coils with foaming cleaner and fin combs, straightening damaged fins to restore airflow. We also clear the concrete pad and check refrigerant lines for insulation damage. Boerne condenser cleanings typically run $120-$220.
Air Handler Cleaning
The air handler is the central station of your HVAC system, and in Boerne’s newer homes with builder-grade flex ductwork, it’s often the first place problems show up. We clean the entire air handler cabinet, including the drain pan and condensate lines that clog with algae and dust in humid conditions. A blocked drain pan overflows, damages ceilings, and creates the moisture that feeds mold inside improperly sealed ducts. Our air handler service includes a camera inspection of accessible duct connections and treatment of the drain system to prevent future blockages. Most Boerne air handler cleanings: $200-$380.
Coil Treatment
After cleaning, we apply a protective coil treatment that inhibits mold and bacterial growth on evaporator and condenser coils. In Boerne’s climate, where high humidity and constant AC runtime create ideal conditions for microbial growth, this treatment extends the time between deep cleanings and keeps your system smelling fresh. The treatment is non-toxic, EPA-registered, and safe for occupied homes. We include it as an add-on to any coil cleaning service for $45-$85.
Heat Exchanger Cleaning
For Boerne homes with gas furnaces, the heat exchanger is a critical safety component that also affects efficiency. Soot and corrosion reduce heat transfer and can create dangerous combustion conditions. Our technicians inspect heat exchangers with cameras and clean accessible surfaces without disassembling the furnace. If we find cracks or deterioration, we document it and recommend repair or replacement before heating season. Heat exchanger cleaning in Boerne typically runs $160-$290.

Trusted Brands We Service in Boerne
We specify professional-grade equipment from Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors use, not the consumer-grade units sold at big-box stores. Our Rotobrush contact cleaning system agitates and extracts debris from duct walls without damaging flex ductwork, which matters in Boerne’s newer homes where builder-grade ducts are thinner and more fragile than older galvanized systems. We stock common replacement parts and media filters for Boerne customers, so most jobs don’t wait on shipping. When your system needs a component we don’t carry, our supplier relationships mean next-day delivery to the Hill Country, not next-week.
Common HVAC Cleaning Problems We See in Boerne Homes
- Builder-grade flex ductwork in master-planned communities retains construction debris. Homes in Esperanza, Mirror Oak, and similar 78015 developments were built with flex ductwork that traps limestone caliche dust and drywall particulate from fast-track Hill Country construction. Post-construction duct cleaning is often skipped, so this fine white powder recirculates for years, clogging filters and coating coils.
- Improperly sealed flex ducts grow mold after Boerne’s intense rainstorms. The short-burst storms that roll off the Balcones Escarpment spike indoor humidity. When flex duct connections aren’t sealed to code, moist air infiltrates the duct cavity. We’ve found mold growth inside ducts in homes less than five years old, especially where attic insulation was compressed during installation.
- Cedar pollen infiltration during December-February creates a unique Boerne problem. Boerne sits in the densest concentration of Ashe juniper in the Texas Hill Country. That ultra-fine pollen infiltrates return systems at volumes that coat ductwork and recirculate for months. Homes near the 78006 corridor with original duct configurations never sized for modern filtration are especially vulnerable.
- Older 78006 homes have ductwork never designed for current AC loads. The mid-century ranch homes and historic stone cottages in this ZIP were built before central air was standard. Original duct configurations are undersized, unsealed, and leak conditioned air into attics and crawl spaces. Cleaning these systems reveals decades of accumulated debris and often identifies the airflow restrictions causing uneven cooling.

FAQs - HVAC Cleaning in Boerne
Builder-grade flex ductwork in these 78015 communities traps limestone caliche dust and drywall particulate from fast-track construction, and post-construction duct cleaning is routinely skipped. The fine white powder recirculates through your system, clogging filters within weeks, while improperly sealed duct connections allow humid air to enter and grow mold after Boerne’s intense rainstorms. We recently serviced a home in Esperanza where the builder-grade flex ductwork was coated with fine white caliche limestone dust from Hill Country lot grading, clogging the filter housing within weeks of move-in. Our Rotobrush system removed the powder and we applied a coil treatment to prevent mold in the humid AC environment. Call (844) 685-6342 for a free inspection - estimates are free.
Boerne sits in the densest concentration of Ashe juniper in the Texas Hill Country, making December-February cedar pollen events uniquely brutal here compared to surrounding cities. This ultra-fine pollen infiltrates HVAC return systems at volumes that coat ductwork and then recirculate through homes for months, driving a post-cedar-season duct cleaning demand that is a Boerne-specific seasonal pattern. The pollen particles are small enough to pass through standard filters and accumulate on coils and blower wheels, reducing efficiency and aggravating allergies. Many Boerne homeowners schedule HVAC cleaning in March, right after peak cedar season. Call (844) 685-6342 to book your post-cedar cleaning - estimates are free.
March, after cedar pollen season ends, and October, before heavy AC runtime begins, are the two optimal windows for Boerne homeowners. March cleaning removes the accumulated cedar pollen and winter dust before spring allergies peak. October cleaning prepares your system for the long May-October cooling season ahead, when Boerne’s position on the Balcones Escarpment means near-constant AC operation. That said, we clean systems year-round, and if you’re seeing white dust from vents or smelling mustiness, waiting for an optimal season isn’t worth the air quality impact. Call (844) 685-6342 - we’ll fit you in when you need it, estimates are free.
Yes, and we take extra care with these systems. The mid-century ranch homes and historic stone cottages in 78006 often have original duct configurations that were never sized or sealed to modern standards, which means restricted airflow and coils that run colder than designed, accelerating frost and dirt buildup. We use low-pressure foaming agents and soft-bristle brushes that clean thoroughly without damaging older refrigerant lines or fragile fins. We also camera-inspect accessible duct connections to identify the leaks that are probably making your coil dirty faster than it should be. Call (844) 685-6342 for a free estimate.
Yes - that white powder is caliche limestone dust from Hill Country lot grading, and it’s one of the most common complaints we hear from homeowners in 78015 new-build communities. This dust settles into HVAC systems before flooring and drywall are even finished, and when post-construction duct cleaning is skipped, it recirculates indefinitely. Our Rotobrush system physically agitates and extracts this powder from duct walls, and we clean the air handler and coils where it accumulates most densely. After a proper cleaning, paired with a high-MERV filter changed on schedule, most Boerne homeowners see the dust problem resolve dramatically. Call (844) 685-6342 for a free inspection and exact quote.
