New Braunfels isn’t a suburb we tacked onto a service map. We’ve watched the city explode from a quiet German-settled town into one of the fastest-growing large cities in the country, and that growth created a specific kind of HVAC problem you won’t find in San Antonio or Austin. The caliche dust from active construction sites, the river valley humidity, the builder-grade equipment installed by the truckload - we see it every week in ZIP codes 78130, 78131, 78132, and 78135. That’s why we keep Rotobrush and Abatement Technologies equipment ready for the drive up from our main office, and why our technicians can spot a construction-compromised duct system before they open the first register.
Why Bellows Air Duct & Vent Co. Is New Braunfels’s Preferred HVAC Cleaning Company
We’ve built our reputation in New Braunfels the old way: showing up on time, doing what we said we’d do, and standing behind it. Our 90-Day Done Right Promise means if the work isn’t right, we return at no charge - no paperwork, no arguing. That promise is stamped on every job, and it’s why homeowners in Veramendi and Meyer Ranch call us back when their neighbors need a referral.
Our reviews from New Braunfels customers consistently mention the camera inspection. We show you the inside of your ducts before we start and after we finish - a visual record, not just a claim. One homeowner in 78130 told us she’d had three other companies quote her, and none had offered to let her see what was actually in her system.
Response time to New Braunfels is typically same-day or next-day, depending on season. Calls are answered by a live person, 24 hours a day - not a voicemail, not an app. When the mountain cedar pollen is surging in January and your system’s struggling, that matters.
We also know the local codes and the local conditions. The Comal and Guadalupe river valleys trap humidity differently than the Hill Country ridgeline just west of town. A technician who doesn’t understand that difference might clean your coils and miss the mold growing in your flex duct insulation. We don’t miss it.
Our HVAC Cleaning Services in New Braunfels
Evaporator Coil Cleaning
The evaporator coil is where your system actually cools the air, and in New Braunfels it’s under constant assault. Caliche dust from construction sites is ultrafine - it passes right through standard 1-inch fiberglass filters and packs onto the coil fins, reducing airflow and forcing your compressor to work harder. At a five-year-old home in Vintage Oaks (78132), we opened the air handler to find caliche dust caked on the evaporator coil and blower wheel. The builder had installed a standard 1-inch fiberglass filter, which was overwhelmed by the fine dust. After cleaning the coil and ductwork, we installed a Honeywell media filter cabinet and applied an antimicrobial coil treatment to guard against mold from the river valley humidity. A typical evaporator coil cleaning in New Braunfels runs $180-$340.

Blower Cleaning
The blower wheel moves every cubic foot of air your home breathes, and when it’s coated with dust, your system can’t move the volume it was designed for. In New Braunfels tract homes, we regularly find blower wheels with a quarter-inch of caliche buildup - the kind of restriction that makes a 3-ton system perform like a 2-ton. We remove the blower assembly, clean it with professional-grade equipment, and balance it before reinstallation. Most blower cleaning in New Braunfels is $150-$280.

Condenser Cleaning
Your outdoor condenser coil rejects the heat your system pulls from your home, and in New Braunfels it sits through dust storms, cottonwood season on the Guadalupe, and the occasional hail event. A dirty condenser can’t shed heat efficiently, so your electric bill climbs while your comfort drops. We wash the coils with foaming cleaner and a low-pressure rinse - never a pressure washer, which can fold the delicate aluminum fins. Condenser cleaning in New Braunfels typically costs $120-$220.

Air Handler Cleaning
The air handler is the central station of your HVAC system, and in New Braunfels’s newer homes it’s often installed in a baking-hot attic with flex duct running in every direction. We clean the entire cabinet, including the drain pan and drain line - critical in river-valley humidity, where a clogged drain can overflow and damage your ceiling in a single afternoon. Air handler cleaning in New Braunfels runs $200-$380 depending on accessibility and condition.

Coil Treatment
After cleaning, we apply an antimicrobial coil treatment that creates a protective barrier against mold and bacterial growth. In New Braunfels, where the Comal and Guadalupe rivers sustain elevated humidity year-round, this isn’t an upsell - it’s a practical defense against the conditions your system lives in. The treatment is $85-$150 when performed with a coil cleaning.

Heat Exchanger Cleaning
For homes with gas furnaces, the heat exchanger is where combustion happens, and any obstruction or corrosion is a safety issue we take seriously. We inspect with cameras and clean only when appropriate, following manufacturer specifications. Heat exchanger cleaning in New Braunfels is $220-$400.

Trusted Brands We Service in New Braunfels
We maintain professional-grade equipment from Rotobrush, Abatement Technologies, and Aprilaire - the same brands serious HVAC contractors specify for their own jobs. For New Braunfels customers, that means we can source replacement media for Honeywell filter cabinets and Aprilaire air cleaners without the two-week wait you’d get ordering online. We stock common sizes for the 78132 and 78135 subdivisions where these systems are most frequently installed, and our technicians carry antimicrobial treatments formulated specifically for high-humidity river valley conditions. When your system needs something we don’t have on the truck, we know the local suppliers in San Antonio and can usually have it next day.
Common HVAC Cleaning Problems We See in New Braunfels Homes
- Builder-grade filters overwhelmed by caliche dust. The 1-inch fiberglass filters installed in most tract homes from 2010 onward were never designed to capture the fine caliche dust generated by active construction. That dust packs onto evaporator coils and blower wheels within the first two to five years of occupancy, reducing system efficiency by 15-30% before most homeowners notice a problem.
- Attic flex duct trapping river valley humidity. Slab-on-grade homes in 78132 and 78135 almost universally use attic-run flexible ductwork, which bakes at extreme temperatures all summer. When insulation is compromised by condensation from the humid air below, mold colonizes the liner - and that mold spools into your living space every time the blower cycles.
- Oversized systems short-cycling in tight new construction. Many tract homes were built with HVAC systems sized for maximum load rather than actual load, causing the system to start and stop rapidly without running long enough to dehumidify. The result is cool but clammy air, and ductwork that never dries out enough to prevent microbial growth.
- Mountain cedar pollen loading return ducts each winter. New Braunfels sits at the southern edge of the Texas Hill Country, and the December-through-February Ashe juniper pollen surge is among the heaviest in the state. That ultrafine pollen loads return-air ducts and overwhelms standard filtration, coating the entire system in a sticky yellow film that ordinary dusting won’t remove.

FAQs - HVAC Cleaning in New Braunfels
That white dust is almost certainly caliche, the calcium-carbonate-rich soil common to the Texas Hill Country. In New Braunfels’s rapidly built subdivisions like Vintage Oaks and Veramendi, HVAC systems were often commissioned while earthmoving equipment was still grading adjacent lots, pulling caliche dust directly into ductwork and sealing it inside. Standard 1-inch fiberglass filters can’t capture particles that fine, so the dust circulates until it packs onto your evaporator coil and blower wheel. We see this in homes only two to five years old. Call (844) 685-6342 for an exact quote - estimates are free.
Yes, the Comal and Guadalupe river valleys trap humidity at levels higher than surrounding Hill Country areas, and that moisture drives year-round mold colonization inside ductwork. When attic insulation is compromised or systems are oversized and short-cycle, condensation forms in flex duct liners and creates ideal conditions for microbial growth. Our coil treatment and duct sanitizing services are specifically formulated for these river-valley conditions. Call (844) 685-6342 for an exact quote - estimates are free.
For homes built since 2010 in ZIPs 78132 and 78135, we recommend a full system inspection every two to three years, with coil and blower cleaning as needed. The combination of construction debris sealed into new ductwork and river-valley humidity creates accelerated buildup compared to older homes in 78130. If you’re still on the original builder-grade filter, annual filter upgrades are the minimum. Call (844) 685-6342 for an exact quote - estimates are free.
Yes, typically by 15-25% if the coil was significantly fouled. A clean evaporator coil transfers heat properly, so your compressor doesn’t run as long or work as hard to achieve the same temperature. In New Braunfels, where caliche dust packs coils tighter and faster than ordinary household dust, the improvement is often dramatic - homeowners report cooler air and lower electric bills within the first billing cycle. Call (844) 685-6342 for an exact quote - estimates are free.
Coil treatment is an antimicrobial application we apply after cleaning your evaporator coil, creating a protective barrier that inhibits mold and bacterial regrowth. In New Braunfels, where river-valley humidity keeps ductwork moist year-round, this treatment extends the benefit of cleaning and helps prevent the musty odors and allergen loads that come from microbial colonization. It’s $85-$150 when performed with a coil cleaning. Call (844) 685-6342 for an exact quote - estimates are free.
