Fast, Reliable HVAC Cleaning Across Converse
HVAC cleaning in Converse means dealing with a specific set of problems: heat-brittled duct seals, years of accumulated dust from new construction, and fine limestone particles that settle into every return vent. Most standard HVAC cleanings in Converse run $450 – $850 for a typical single-family home, depending on system size and how much sealing work the ducts need. Our crews know the neighborhoods off Toepperwein Road, the subdivisions east of I-35, and the older brick ranches where original flex-duct is finally giving out. Call (254) 347-3897 for a written, no-pressure estimate before any work starts.
Why Cardinal Air Duct San Antonio Is Converse’s Preferred HVAC Cleaning Company
Our HVAC Cleaning team works in Converse weekly, and we’ve learned what these homes actually need. The 1970s and 1980s brick ranches here share a common thread: ductwork routed through vented attics that bake under the Texas sun every summer. Seals crack. Flex-duct sleeves soften and sag. Attic insulation drifts into gaps. Homeowners don’t notice because the air still blows, just weaker and dustier than it should.
Omar Haddad leads our Converse crews, and he’s personally walked dozens of these attics. Every job includes a written price before we touch a single duct, a written guarantee on any repair, and a free second visit if something isn’t right. That’s the 365-Day Done Right Promise, and it applies to every booking in Converse without exception. You’ll know the technician’s name before they arrive, and they’ll show up in uniform with Rotobrush and Nikro equipment, not a truck-mounted shop vac.
Styles & brands we work with




AC Duct Cleaning in Converse
AC Duct Cleaning in a Converse home is rarely just about dust. It’s about restoring airflow through ducts that have been quietly failing for years. When we clean a system here, we start with a camera inspection of the supply and return trunks. In Converse, that inspection usually finds one of three things: crushed flex-duct runs, separated connections where ducts have pulled apart at the boot, or seals that have turned brittle and started leaking attic air into the system.
A full source-removal cleaning on a typical Converse ranch runs $450 – $700. The process uses a Rotobrush rotary brush system to agitate debris inside the duct walls, paired with a Nikro HEPA vacuum pulling negative pressure at the trunk. Negative-pressure extraction means loosened debris goes straight into the vacuum, not back into your living room. We clean supply ducts, return ducts, the plenum, and the registers.
Sealing What the Heat Broke
After the cleaning, we address the seals. In Converse’s vented attics, duct tape and original mastic from the 1980s have usually failed. We reseal connections to NADCA standards using proper mastic and UL-rated tapes. Sealing is a separate line item, typically $150 – $300 depending on how many connections need work. It’s the step that makes the cleaning actually last.
Return Vent Clog Removal
Return vents in Converse clog faster than in most nearby cities. Construction dust from the new developments along FM 1516 and the quarry operations east of town create a fine particulate that packs into return grilles. We remove and wash every return grille during a cleaning, and we’ll show you before-and-after photos of what came out.
Furnace Cleaning in Converse
Furnace Cleaning in Converse matters even though winters are short here. The furnace shares the same blower, same ducts, and same return path as your AC. When dust and debris settle in the blower wheel and heat exchanger during the long cooling season, the furnace runs hot and inefficient when you finally switch it on in November. A furnace cleaning in Converse typically runs $300 – $500 as a standalone service, or it’s bundled with AC duct cleaning for the full system.
Blower Wheel and Motor Service
The blower wheel is where Converse dust does its worst damage. Fine limestone particles coat the wheel blades, throwing it out of balance and straining the motor bearings. We pull the blower assembly, clean each blade, and inspect the motor. A blower wheel that’s too far gone gets replaced, and that’s a conversation we’ll have with you before any work is done, with a price in writing.
Heat Exchanger Inspection
We inspect the heat exchanger during every furnace cleaning. This isn’t a sales tactic. In older Converse homes that ran their systems hard for 30-plus years, hairline cracks in the exchanger are a legitimate safety concern. We check for cracks, rust, and improper flame color. If we see a problem, we recommend a licensed HVAC tech, and we’ll put that recommendation in writing too.
Trusted Brands We Service in Converse
We work on all major HVAC brands found in Converse homes: Carrier, Trane, Lennox, Rheem, Goodman, and American Standard. Our trucks carry common filters and replacement components from Aprilaire and Guardsman, which means we can often complete filter upgrades or coil treatments the same day without a second trip. For duct cleaning, we run Abatement Technologies containment systems when a job calls for it, usually in homes with significant mold or heavy debris in the ductwork. You’ll see the equipment before we start, and we’ll explain exactly what it’s doing.

AfterCommon HVAC Cleaning Problems We See in Converse Homes
- Heat-brittled duct seals. Decades in a vented attic turn mastic and tape into crumbly dust. Attic air and insulation enter the system between cleanings, and your indoor air quality drops even when filters are fresh.
- Crushed or disconnected flex-duct runs. Air still leaks through the gaps, so the system feels like it’s working. Then you check a room and realize it’s never reaching temperature. A camera inspection during cleaning is how we find these.
- The ‘Converse crunch’ on return vents. Quarry fines and construction dust from continuous new development pack into return grilles, sometimes within 4 – 6 months of a cleaning. Frequent filter changes and annual cleaning are the only real fix.
- Musty smells after heavy rain. High humidity plus dust accumulation inside ducts creates a breeding ground for microbial growth. If moisture is present, we treat the ducts and address the source of the water, not just the smell.
Pricing for HVAC Cleaning in Converse, TX
A complete HVAC cleaning in Converse, covering both AC duct cleaning and furnace cleaning, typically runs $450 – $850 for a standard single-family home. The range depends on three things: the number of supply and return runs, whether the ducts need sealing work after cleaning, and whether we find crushed flex-duct that needs replacing. A routine AC duct cleaning alone sits closer to $450 – $700. Furnace-only cleaning runs $300 – $500. Sealing work adds $150 – $300. Coil treatment, if your evaporator coil has heavy microbial growth, adds $100 – $250 depending on access. You’ll get a written price before any work begins, and that price does not change at the door. Call (254) 347-3897 for a free estimate.

FAQs About HVAC Cleaning in Converse
Most Converse homes need HVAC cleaning every 12 months, and the reason is specific to this area. The combination of limestone quarry dust and ongoing construction particulate means return vents and duct interiors accumulate debris faster than in, say, New Braunfels or Cibolo. Annual cleaning keeps the blower wheel balanced, the return path clear, and the air in your home measurably cleaner. Call (254) 347-3897 to schedule, and we’ll give you a written quote before we book.
Yes, but it requires care and the right equipment. Original flex-duct from the 1970s and 1980s is often brittle from decades in a vented attic. We use a lower-torque setting on our Rotobrush for older material and inspect every run for sleeve tears before cleaning begins. If a run is too fragile, we’ll tell you before we touch it, give you a replacement price, and let you decide. We’d rather have that conversation than quietly destroy a duct.
Partly. The smell usually comes from microbial growth inside ducts that have accumulated dust and absorbed moisture during humid periods. A full source-removal cleaning removes the organic material, but the root cause is moisture. We check for standing water in the drain pan, condensation on the coil, and humidity entering through failed duct seals. We clean, we treat, and we point out the water source so the problem doesn’t return in six months.
Check your return grilles. If they’re coated with a fine gray-white film that reappears within weeks of wiping them down, that’s the Converse crunch. You’ll also notice reduced airflow from supply registers in rooms farthest from the air handler, and your filter will look dirty well before its rated replacement interval. A camera inspection confirms it in about 20 minutes. Call (254) 347-3897 and we’ll schedule one.
Yes, every job covers the full loop: supply ducts, return ducts, the plenum, the blower compartment, and all registers. Skipping the return side is pointless, especially in Converse where returns clog faster than supplies. You’ll get before-and-after photos of both, and a written report of what we found, including any sealing or replacement work we recommend.
