Terrell Hills sits inside San Antonio’s perimeter, but it’s its own incorporated municipality with its own rules. That matters when we’re working on homes built between the late 1930s and early 1970s, because many of these large, custom-built houses have HVAC systems that predate any consistent local inspection program. We’ve been serving this area for over 42 years, and we’ve learned that Terrell Hills homes demand a different approach than the tract housing in newer suburbs.

Why Bellows Air Duct & Vent Co. of San Antonio Is Terrell Hills’s Preferred HVAC Cleaning Company

We’ve worked in Terrell Hills long enough to recognize the telltale signs of original galvanized metal supply trunks and the particular way duct-board returns deteriorate after decades in attics that hit 140°F+ every July and August. Our HVAC Cleaning team doesn’t treat a 4,500 sq ft colonial with extensive return-air networks the same as a 1,800 sq ft starter home. Wade Kellerman, who leads our company, insists on this distinction. Wade Kellerman built Bellows on the principle that you can’t clean what you don’t understand.

Our 90-Day Done Right Promise applies to every Terrell Hills job in writing. If something isn’t right, we return at no charge. No paperwork, no arguing. We also answer our phones with a live person 24 hours a day, not a voicemail tree, because Terrell Hills homeowners tend to call when they notice a problem, not browse websites for hours.

Most of our Terrell Hills appointments are scheduled within a day or two, and emergency calls get same-day response when possible. We complete most jobs in a single visit by background-checked, uniformed technicians who carry professional-grade Rotobrush and Nikro equipment. Every job gets a camera inspection before and after, so you see what was in your system and what we removed.

Our HVAC Cleaning Services in Terrell Hills

Evaporator Coil Cleaning

The evaporator coil in your Terrell Hills home works harder than almost any component. From June through September, these large older homes run cooling nearly continuously, and that constant load means coils accumulate debris faster than in newer, better-sealed systems. A dirty evaporator coil restricts airflow, reduces cooling capacity, and can cause ice buildup that damages the compressor. We clean coils with foaming agents and low-pressure rinses that won’t bend delicate fins, then verify the result with our camera system. In Terrell Hills, where many systems are 20+ years old, this service often restores capacity the homeowner didn’t realize they’d lost.

Blower Cleaning

The blower assembly moves every cubic foot of air through your Terrell Hills home, and when it’s coated with dust and pollen, it can’t push air efficiently through those sprawling ranch or colonial floor plans. We remove the blower housing, clean the wheel and motor assembly, and check belt tension and bearing condition. For the 2,500-5,000+ sq ft homes common here, a clean blower means the system doesn’t have to run as long to reach temperature. That matters when you’re paying to cool spaces built in an era before anyone worried about energy efficiency.

Condenser Cleaning

Your outdoor condenser unit in Terrell Hills battles cottonwood fluff, Ashe juniper debris, and the fine caliche dust that blows up from south Texas construction sites. We clean condenser coils with foaming cleaner and fin combs, clear the base pan of debris that traps moisture, and verify proper refrigerant pressures. A clean condenser transfers heat properly. In Terrell Hills, where cooling systems run 100+ days straight, that efficiency difference shows up on your CPS Energy bill.

Air Handler Cleaning

The air handler is the central station of your HVAC system, and in Terrell Hills homes with original or once-updated metal trunk-and-branch distribution, it’s often the only point where all return air converges before conditioning. We clean the entire air handler cabinet, including the drain pan and condensate lines that can clog with algae and overflow into ceilings. Many Terrell Hills homes have air handlers in attics or crawl spaces that have never been properly accessed. We document everything with camera footage.

Heat Exchanger Cleaning

For homes with gas furnaces, the heat exchanger is where combustion happens, and any blockage or corrosion here is a genuine safety concern. We inspect heat exchangers with borescope cameras, clean where accessible, and flag any cracks or deterioration that could allow carbon monoxide into your living space. In Terrell Hills’s older homes, we’ve found heat exchangers that have run 30+ winters without professional inspection. We don’t give DIY instructions for this work. The consequences of a mistake are too serious.

Trusted Brands We Service in Terrell Hills

We clean and maintain systems built around Honeywell and Aprilaire controls and media filters, and we carry Rotobrush and Nikro professional-grade cleaning equipment that serious HVAC contractors specify for their own jobs. For Terrell Hills homeowners, this means we don’t need to order parts or schedule return visits for equipment we don’t stock. Most cleaning jobs finish in one day because our trucks carry what the job demands. If your system uses specialized components, we identify them during our upfront inspection and tell you before work starts whether anything requires ordering.

Common HVAC Cleaning Problems We See in Terrell Hills Homes

• Original galvanized trunks never professionally cleaned. Because Terrell Hills is its own incorporated municipality with independent permitting, many 1950s-60s homes have original galvanized supply trunks and deteriorating duct-board returns that were never inspected or cleaned under any jurisdiction’s maintenance program. The first professional cleaning often reveals decades of accumulated debris.
• Duct-board liner degradation from extreme attic heat. San Antonio’s summer attic temperatures regularly exceed 140°F, and over decades this degrades the interior liner and insulation of older duct board. The surface sheds particulate matter directly into your airstream. You can’t see it at the register, but our cameras show the erosion.
• Ashe juniper pollen loading during Cedar Fever season. From December through February, pollen counts in this area rank among the highest in the nation. Terrell Hills’s large, voluminous duct systems become reservoirs that recirculate allergens through high-value homes whose owners have both the means and motivation to address indoor air quality.
• Under-serviced return-air networks in sprawling floor plans. Those 2,500-5,000+ sq ft ranch and colonial layouts require extensive return-air ductwork that many cleaning companies skip or can’t properly access. We clean the full network, not just what’s easy to reach.
