We’ve been driving out to Converse from our San Antonio route for more than four decades, long before FM 78 widened and before the retail corridors along Seguin Road filled in. We know the difference between a 1978 ranch near Randolph AFB with original fiberglass duct board and a 1990s split-level off Gibbs Sprawl Road with flex-duct baked brittle in a 140°F attic. That local knowledge matters because the wrong cleaning approach for one system type can damage it, and the wrong diagnosis of an airflow problem can leave you paying for work that doesn’t solve the root cause. Our HVAC Cleaning team treats Converse as a distinct market, not a ZIP code on a spreadsheet.
Why Bellows Air Duct & Vent Co. Is Converse’s Preferred HVAC Cleaning Company
Converse sits immediately adjacent to Joint Base San Antonio-Randolph, and that proximity shapes everything about the housing stock we service. A large share of Converse homes cycle through military families on 2-3-year PCS orders, which creates a pattern we’ve documented for years: ductwork that has housed four or five families in a decade but has never once been professionally cleaned. This isn’t a theoretical problem. We see it in the field constantly - systems with 15 years of accumulated debris that the current occupants assume is normal because they’ve never known anything different.
Our reputation in Converse is built on showing homeowners what was actually in their system. Every job starts and ends with a camera inspection. You see the before. You see the after. There’s no claim without proof. Our 90-Day Done Right Promise applies to every Converse job in writing: if the work isn’t right, we return at no charge with no paperwork required.
Calls are answered by a live person, 24/7 - not a voicemail tree, not an app. Most Converse customers who call in the morning have a technician that afternoon or the following morning. Background-checked, uniformed technicians arrive in marked vehicles, and the price quoted on the phone is the price on the invoice. We’ve operated this way since 1984 because it’s the only way that doesn’t create problems later.
Our HVAC Cleaning Services in Converse
Air Handler Cleaning
Air handler cleaning is the most critical service we perform in Converse, and it’s the one most often skipped by discount operators. Converse’s attic-mounted air handlers sit in extreme heat for months each summer, with attic temperatures regularly exceeding 140°F. That heat degrades flex-duct connections, dries out drain pan seals, and turns accumulated dust into a hardened mat that restricts airflow and forces the blower motor to work harder. We remove the blower assembly, clean the evaporator coil housing, treat the drain pan for algae and mold, and reassemble with new gaskets where needed. A clean air handler in a Converse attic can drop your summer electric bill measurably - we’ve seen 15-20% reductions in homes where the unit was badly clogged.

Evaporator Coil Cleaning
The evaporator coil is where cooling actually happens, and in Converse it’s under constant assault. Summer humidity stays high enough that any dust layer on the coil becomes a wet, microbial breeding ground within days. Add the mountain cedar pollen that blows through Converse’s flat northeastern corridor from December through February, and you have a coil that can be fully blocked by a felt-like mat of organic material. We use foaming cleaners and low-pressure rinses that remove debris without bending the delicate aluminum fins. For Converse homes with persistent humidity issues, we also apply a coil treatment that inhibits mold regrowth for the season. A typical evaporator coil cleaning in Converse runs $189-$275.

Heat Exchanger Cleaning
Heat exchanger cleaning is non-negotiable for gas furnace safety, and in Converse’s older 1970s-1980s tract homes, these units have often run for decades without proper inspection. Cracked or corroded heat exchangers can leak carbon monoxide into the living space. Our technicians visually inspect the exchanger with a borescope camera, clean combustion chambers of soot and debris that reduce efficiency, and test flue draft to confirm safe operation. If we find a compromised exchanger, we document it with photos and explain your options without pressure. Heat exchanger cleaning and inspection in Converse typically costs $225-$340.

Blower Cleaning
The blower wheel is the engine of your airflow, and when it’s coated with dust, it becomes an imbalanced load that strains the motor and moves less air. In Converse, we frequently find blower wheels caked with the same layered sediment that clogs returns - caliche dust from unpaved lots and construction sites, compacted with cedar pollen into a material that doesn’t brush off easily. We remove the wheel, clean it in a contained wash station, balance it, and reinstall. Blower cleaning as a standalone service in Converse runs $165-$240, though it’s usually bundled with air handler or coil cleaning for better value.

Condenser Cleaning
Your outdoor condenser coil rejects the heat your system collects indoors, and in Converse it operates in an environment of caliche dust, cottonwood fluff, and lawn debris. A dirty condenser can’t shed heat efficiently, so your system runs longer, wears faster, and costs more to operate. We clean condenser fins with foaming cleaner and low-pressure water, straighten bent fins, and check refrigerant pressures to confirm the system is charged correctly. Condenser cleaning in Converse typically costs $145-$195.

Coil Treatment
For Converse homes that struggle with mold or mildew odors, particularly in humid summer months, we apply an antimicrobial coil treatment after cleaning. This isn’t a cover-up fragrance - it’s a bonded treatment that inhibits microbial growth on the coil surface for the cooling season. We use products from Guardsman that are specified for HVAC applications and won’t off-gas into your living space. Coil treatment adds $65-$95 when performed with a coil cleaning.

Trusted Brands We Service in Converse
We clean and service equipment from every major manufacturer, and we maintain professional-grade cleaning systems from Rotobrush and Nikro for duct and component cleaning. For coil treatments and antimicrobial applications, we use Guardsman products formulated specifically for HVAC systems. We don’t show up with shop-vacs and brushes from the hardware store. The equipment we deploy in Converse is the same specification that commercial HVAC contractors use, because residential systems in this market - particularly the older units in original Randolph-area housing - need that level of capability to be cleaned thoroughly without damage. We stock common replacement parts for faster turnaround, and if your system needs a component we don’t carry, our supplier relationships in the San Antonio metro usually get it next-day.
Common HVAC Cleaning Problems We See in Converse Homes
- Layered caliche and cedar sediment in returns. Technicians miss this hidden restriction in flex-duct bends, leaving airflow problems that spike utility bills. We pull the sediment with rotary brush systems and verify flow restoration with before-and-after camera documentation.
- Fiberglass duct board shedding liner debris. 1980s tract homes in Converse frequently used fiberglass duct board that degrades internally. Cleaning without sealing exposed surfaces recontaminates the system within weeks. We identify duct board during inspection and recommend appropriate remediation.
- Mold regrowth in attic-mounted air handlers. Cleaning without addressing the 140°F+ attic environment and lingering humidity leads to mold returning within 30 days. We treat drain pans, check condensate drainage, and apply antimicrobial coatings where appropriate.
- Assumed undersizing in rental turnovers. Incoming military families near Randolph assume high bills mean the AC is too small, when the actual problem is a return grille packed with a decade of deferred maintenance. We measure actual airflow and static pressure to diagnose correctly.

FAQs - HVAC Cleaning in Converse
That white dust is almost certainly degraded fiberglass liner from original duct board, common in 1970s-1980s Converse tract homes. The material sheds when disturbed during cleaning. We identify duct board during our pre-cleaning camera inspection and seal exposed surfaces after cleaning to prevent recontamination. If you’re seeing this now from a previous company’s work, call (844) 685-6342 - we can assess whether the liner needs sealing or replacement.
Yes, and we see this constantly in Converse rentals. A new condenser and coil can’t move air through a return packed with caliche dust and cedar pollen. We measure static pressure and airflow to isolate whether the problem is the equipment or the distribution system. In most cases, the unit is properly sized but the ductwork is restricted by years of deferred maintenance across multiple tenants. A full cleaning with airflow verification typically resolves it. Call for a free estimate.
Our Rotobrush and Nikro systems use flexible shafts and compact heads designed specifically for restricted access. For Converse’s low-clearance attics, we break down equipment into components that fit through scuttle holes, then reassemble in the attic. We’ve cleaned systems with less than 24 inches of headroom. The camera inspection confirms we reached every branch, regardless of space constraints.
Cleaning removes existing mold and organic loading, but prevention requires addressing moisture sources. In Converse’s humid climate, we treat evaporator coils and drain pans with antimicrobial coatings, verify condensate drainage is clear, and check that attic air handlers aren’t reintroducing humidity through poorly sealed return plenums. Cleaning alone helps; cleaning plus moisture control lasts. Ask about our coil treatment add-on when you call.
It is safe if the duct board was properly inspected and any exposed or degraded liner was sealed during the cleaning process. Unsealed fiberglass duct board can shed particles into the airstream. Our technicians flag duct board during the initial camera inspection, explain what we found, and seal affected sections with appropriate encapsulants before the system is restarted. We document this in your after-cleaning report. If a previous cleaner didn’t do this, we can assess and correct it. Call (844) 685-6342.
