Fast, Reliable HVAC Cleaning Across Leon Valley
Most HVAC cleaning jobs in Leon Valley run $280-$620 and are finished in a single visit, with same-day scheduling available when you call early. We’re Bellows Air Duct & Vent Co. of Texas, and we’ve been driving out to Leon Valley from our Houston headquarters for over 42 years, working on the same ranch homes that built this city. You know the ones - single-story slabs off Bandera Road, Grissom Road, and the neighborhoods near Leon Valley Community Center, with attic duct systems that haven’t been touched since the Carter administration. We answer our phones live, 24 hours a day, at (866) 347-2063. No app. No voicemail. A real person who can get a background-checked, uniformed technician to your door with the right equipment for what Leon Valley homes actually need.
Why Bellows Air Duct & Vent Co. of Texas Is Leon Valley’s Preferred HVAC Cleaning Company
We’ve earned our reputation in Leon Valley one job at a time, mostly through neighbors telling neighbors. Our technicians know the difference between a 1972 ranch on the east side of town and a 1984 build near Evers Road - and they know both have ductwork that’s been baking in 130°F attics for decades. Wade Kellerman, who leads our company, insists we treat every Leon Valley home like we’re coming back to it, because we often do: for the $89 Seasonal Tune-Up, for dryer vent cleaning, or just to check that the job we did six months ago is still holding.
Our reviews from Leon Valley customers mention the same things repeatedly - that we showed up when we said we would, that the price on the phone matched the price on the invoice, and that the camera footage of their before-and-after ductwork was enough to make them call their sister in Alamo Heights. We don’t chase five-star ratings; we chase the kind of customer who stays in a house for twenty years and wants the work done so right they never have to think about it again.
Response time to Leon Valley is typically same-day or next-morning, depending on when you call and what’s happening with cedar pollen season. January and February, when Mountain Cedar peaks, our schedule fills fast. We recommend calling early. (866) 347-2063.
Our HVAC Cleaning Services in Leon Valley
Evaporator Coil Cleaning
The evaporator coil in your Leon Valley air handler is where moisture and pollen meet, and in this city, that means business. Mountain Cedar particles are microscopic, oily, and they stick. Add eight months of continuous AC operation, and you’ve got a coil choked with biofilm that reduces efficiency and blows allergens back into your living room. We pull the coil, clean it with professional-grade foaming agents, and inspect the drain pan for the algae buildup that thrives in San Antonio humidity. A clean coil in Leon Valley can drop your energy bill and your antihistamine bill at the same time.

Blower Cleaning
Your blower motor and wheel are the lungs of the system, and in Leon Valley’s older homes, they’re often working against decades of accumulated caliche dust and degraded flex-duct insulation. When that debris hits the blower wheel, it throws the assembly out of balance, causing vibration, noise, and premature bearing failure. We remove the blower assembly, clean the wheel blade by blade, and check the motor amp draw against manufacturer specs. Most Leon Valley blowers we’ve cleaned haven’t been serviced since the original installation. The difference in airflow is immediate - you’ll feel it in rooms that haven’t cooled evenly in years.

Condenser Cleaning
Your outdoor condenser coil in Leon Valley is fighting cottonwood fluff, cedar pollen, and caliche dust that settles like a film across the fins. A dirty condenser can’t reject heat properly, so your system runs longer, harder, and hotter - especially during those stretches of 105°F days in July and August. We wash the coils with low-pressure foaming cleaner, straighten damaged fins, and check refrigerant levels. In Leon Valley’s climate, this isn’t optional maintenance; it’s what keeps a 20-year-old system alive through another summer.

Air Handler Cleaning
The air handler cabinet in your Leon Valley attic is where everything converges: return air pulled through pollen-laden ducts, condensation dripping in humid summer, and the vibration of a blower that’s been running since the Reagan administration. We clean the entire cabinet interior, replace or clean filters, inspect the heat exchanger for rust or cracks, and seal any gaps where unfiltered attic air is being drawn in. For the ranch homes that dominate Leon Valley, this is often the first time anyone has opened that cabinet with a flashlight and a plan.

Coil Treatment
After we clean your evaporator coil, we apply a specialized coil treatment that inhibits microbial growth and creates a surface less likely to trap pollen and dust. In Leon Valley, where Mountain Cedar season runs December through February and standard cleaning can leave residual particles behind, this treatment extends the effectiveness of your cleaning by months. We use products from Honeywell and Aprilaire, specified for the allergen load this region produces. It’s not a upsell - it’s what we’d want in our own homes during cedar season.

Trusted Brands We Service in Leon Valley
We carry and service professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify when they’re building systems meant to last. For Leon Valley customers, this means we don’t have to order parts from Dallas or wait on shipping when your 1980s air handler needs a specific coil fin comb or a replacement UV bulb. Our trucks are stocked for the equipment we actually encounter in this city’s older housing stock, and our technicians are trained on the quirks of legacy systems that most cleaners won’t touch. Fast turnaround isn’t a slogan here; it’s having the right brush head for a 1960s galvanized trunk line already on the truck.
Common HVAC Cleaning Problems We See in Leon Valley Homes
- Degraded flex-duct insulation dropping debris into airflow. Decades of 130°F-plus attic summers in Leon Valley cook the inner liners of original flex duct until they crack and sag, shedding fiberglass and dust directly into your air stream. We find this on almost every ranch home built before 1985, and it’s why we always camera-inspect before we quote.
- Cedar pollen coating duct interiors with microscopic, sticky residue. Leon Valley sits in the epicenter of North America’s worst Mountain Cedar pollen belt. These particles infiltrate return-air systems, coat evaporator coils, and embed in duct linings where standard vacuums won’t reach. Our HEPA-filtered Rotobrush equipment and coil treatments are specifically specified for this allergen load.
- Caliche dust accumulation in original galvanized trunk lines. The soil around Leon Valley is rich in caliche, a cement-like calcium carbonate that becomes airborne during construction and settles in attic ducts through gaps and unsealed joints. We regularly pull access panels on homes off Bandera Road to find trunk lines with half an inch of this fine, abrasive dust limiting airflow.
- Original sheet-metal ductwork never sealed or insulated to modern standards. The 1960s and 1970s ranch homes that define Leon Valley were built with trunk lines that leak conditioned air into attics and draw unfiltered attic air back into the system. Cleaning without addressing these leaks is temporary; we note them, show you camera footage, and can seal them as a separate service if you choose.

FAQs - HVAC Cleaning in Leon Valley
Leon Valley homes are older, with original duct systems that have never been cleaned and attic conditions that accelerate degradation. The city built out almost entirely between 1960 and 1985, leaving a housing stock of ranch homes with attic-mounted flex duct and galvanized trunk lines that have endured 40-plus years of 130°F summers. Newer suburbs northwest of here have tighter construction, newer materials, and ductwork designed for modern filtration. If your Leon Valley home still has original ducts, they’re likely carrying decades of accumulated debris that newer homes simply haven’t had time to collect. Call (866) 347-2063 and we’ll show you exactly what’s in there.
Mountain Cedar pollen creates a uniquely heavy, sticky allergen load that standard cleaning equipment often fails to fully remove. Leon Valley sits in the heart of North America’s worst Ashe juniper corridor, and the December-through-February pollen event floods outdoor air with microscopic particles that infiltrate return systems and coat coil and duct surfaces. We specify HEPA-filtered Rotobrush equipment and post-cleaning coil treatments specifically because of this pollen’s persistence. Generic duct cleaning without these tools leaves residue that triggers symptoms within weeks. If you’re suffering from cedar fever indoors, your ducts are likely part of the problem. We can show you.
Yes, if the metal is intact and not rusted through, cleaning can restore airflow and reduce allergen circulation significantly. Original galvanized trunk lines in Leon Valley are often structurally sound but coated with caliche dust and pollen residue that restricts airflow by 20% or more. We camera-inspect first - if the metal is corroded or joints have separated, we’ll show you and recommend repair or replacement options with upfront pricing. Cleaning a solid old trunk line costs $320-$480 and can extend its useful life by years. Call for a free inspection and we’ll give you an honest assessment.
Yes, particularly if your return-air ducts have gaps or unsealed joints where caliche dust is being drawn from the attic. Leon Valley’s soil contains high calcium carbonate content that becomes fine, abrasive dust - we find it packed in original trunk lines on homes near Grissom Road and Bandera Road. Thorough duct cleaning removes accumulated deposits, and sealing accessible leaks prevents new infiltration. Most customers notice less frequent dusting and reduced particulate on furniture within two weeks. For an exact quote on cleaning and sealing, call (866) 347-2063 - estimates are free.
We strongly recommend it for Leon Valley homes, especially if anyone in the household suffers from cedar allergies. The post-cleaning coil treatment we apply creates a surface that resists microbial growth and reduces pollen adhesion, extending the effectiveness of your cleaning through Mountain Cedar season. Without it, the oily, microscopic cedar particles that make it past your filter can re-coat the coil within weeks. The treatment adds $85-$120 to a standard coil cleaning and is backed by our 90-Day Done Right Promise. Call (866) 347-2063 to schedule - we’ll apply it while we’re there.
