Houston’s not like other Texas markets. The Gulf humidity here never really quits, and your AC works overtime roughly 10 months out of every year. That combination - near-constant cooling plus 75-90% relative humidity - turns residential ductwork into a mold habitat that cleaners in Dallas or San Antonio simply don’t encounter with the same regularity. We know the local housing stock: the 1970s-1990s slab-on-grade ranches in Katy and Pearland with flex duct baking in 140°F attics, the older pier-and-beam bungalows in the Heights and Montrose with crawl-space runs that flooded during Harvey. We’ve cleaned systems in Meyerland homes where the drywall got replaced after 2017 but the ductwork never did. We bring the right equipment and the right expectations for what Houston conditions do to an HVAC system.
Why Bellows Air Duct & Vent Co. of Texas Is Houston’s Preferred HVAC Cleaning Company
We’ve been serving Houston-area homeowners for over 42 years. In that time, we’ve cleaned ductwork in ranch homes along Brays Bayou, in mid-century builds near Clear Lake, and in the tight crawl spaces of Montrose bungalows. The reviews we receive from Houston customers consistently mention two things: we show up when we say we will, and the price on the phone matches the price on the invoice.
Our response time to Houston is same-day or next-day for most calls. We keep our technicians based in the metro area, not driving in from out of county. Every technician is background-checked and uniformed, and every job starts with a camera inspection of your ductwork - before we touch a tool - so you see what we see.
We don’t use bait coupons or scare tactics. Our HVAC Cleaning team presents one honest price before work begins, and we back every job with our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.
Our HVAC Cleaning Services in Houston
Evaporator Coil Cleaning
The evaporator coil in a Houston home works harder than almost anywhere in the country. With 2,800-3,000 cooling degree days annually, that coil stays wet and active for months on end. In the humidity here, biological growth on the coil is not an occasional problem - it’s the baseline condition we expect to find. A dirty coil restricts airflow, drives up electric bills, and can freeze the system entirely. We clean coils with professional-grade foaming agents and brushes, then verify the improvement with before-and-after camera documentation. In many Houston homes, particularly those with older systems in Katy or Pearland, we find coils that haven’t been accessed in 15-20 years.
Coil Treatment
After cleaning, we apply a coil treatment that inhibits microbial regrowth in Houston’s persistent humidity. This is not a cosmetic step for us. Given the Gulf Coast conditions, a cleaned coil without treatment will often show new growth within a single season. The treatment we use is rated for high-humidity environments and is safe for residential systems. We recommend it for any Houston home where the coil showed visible contamination, and particularly for properties near bayous or in flood-adjacent neighborhoods where mold pressure is elevated.
Air Handler Cleaning
The air handler is the heart of your system, and in Houston it moves an enormous volume of conditioned air year-round. Dust, pollen, and mold spores accumulate in the blower compartment, on the motor, and in the housing. We disassemble and clean the blower assembly, housing, and accessible components, then reassemble and test. In older Houston homes - especially pier-and-beam structures in the Heights - we’ve found air handlers installed in tight closet spaces or converted porches where previous cleaners simply never looked. Our camera inspection catches what a quick visual check misses.
Blower Cleaning
A blower wheel caked with debris moves less air and draws more power. In Houston’s long cooling season, that inefficiency adds up fast on your electric bill. We remove the blower assembly when accessible, clean it off-site if needed, and balance it on reinstallation. For homes in areas like Bellaire or West University Place with mature trees, we often find blower wheels loaded with fine particulate that standard filter changes never caught.
Condenser Cleaning
Your outdoor condenser in Houston battles pollen, cottonwood fluff, and the fine grit that blows in from Gulf construction sites. A dirty condenser can’t reject heat properly, so your system runs longer and harder. We clean condenser coils with foaming cleaner and low-pressure water, straighten damaged fins, and clear debris from the cabinet base. This is basic maintenance, but done right it extends compressor life - and in Houston’s climate, compressor replacement is a costly failure we want to help you avoid.
Heat Exchanger Cleaning
For Houston homes with gas furnaces, the heat exchanger requires periodic inspection and cleaning. Corrosion and soot buildup can compromise the exchanger and create safety risks. We inspect with cameras and clean as indicated, documenting the condition for your records. In the brief Houston heating season, it’s easy to neglect this component, but we check it during every full-system service.

Trusted Brands We Service in Houston
We clean and service systems built with components from Rotobrush, Honeywell, Nikro, and other professional-grade manufacturers. Our trucks carry the tooling and replacement parts to handle most Houston residential systems without a return trip. That matters here. A homeowner in Meyerland or along Brays Bayou doesn’t need to hear that we have to order a part and come back next week. We stock what Houston systems typically need, and our technicians are trained on the equipment brands that local HVAC contractors have installed for decades.
Common HVAC Cleaning Problems We See in Houston Homes
- Collapsed flex duct hidden in attics. Houston’s 1970s-1990s ranch homes - dense in Katy, Pearland, and Clear Lake - used flex duct routed through attics that hit 140-160°F in summer. The duct liner degrades, sections separate internally, and airflow drops while the homeowner blames the AC unit. We find this with our camera inspection before we start any cleaning.
- Flood-silt residues in buried duct runs. After Hurricane Harvey, an estimated 100,000+ Harris County homes had ductwork contamination. Many flex-duct systems were partially submerged and never properly cleaned. We still uncover this in post-Harvey neighborhoods, particularly where homeowners replaced drywall but never addressed the ductwork.
- Mold growth from chronic condensation. Houston’s 75-90% relative humidity and near-continuous AC operation create standing condensation inside poorly insulated flex duct. This is a routine finding for us, not a rare exception. Standard cleaning without addressing the moisture source leaves the problem ready to return.
- Heavy debris from attached workshops and rural properties. Houston’s acreage properties and homes with detached workshops often have separate HVAC units or extended duct runs that collect construction dust, welding particulate, and organic debris. Standard residential cleaning methods won’t handle this load. We bring commercial-grade extraction equipment for these jobs.
Pricing for HVAC Cleaning in Houston, TX
A typical evaporator coil cleaning in Houston runs $180-$340. Blower cleaning is usually $140-$260. Full air handler cleaning ranges $220-$400. Condenser cleaning runs $120-$220. A complete system HVAC cleaning - coil, blower, air handler, and condenser - typically falls between $280-$580 depending on system accessibility and contamination level.
What moves the price: attic access difficulty, system size, contamination severity, and whether flood damage or mold requires specialized handling. We see all of these in Houston. A 1970s ranch in Pearland with a tight attic and Harvey-era duct contamination takes longer than a straightforward service in a newer West University Place build.

FAQs - HVAC Cleaning in Houston
Houston’s chronic 75-90% relative humidity and roughly 10 months of annual AC operation create persistent condensation inside ductwork that drier Texas cities simply don’t experience. This makes mold and microbial growth a baseline condition here, not an occasional problem. We address it with thorough drying, antimicrobial treatment, and camera verification. Call (866) 347-2063 to schedule an inspection.
Proper post-Harvey duct cleaning includes camera inspection of all flex duct runs, not just visible registers and returns. Many homeowners had drywall and flooring remediated but never verified the ductwork. We document before-and-after condition with video, and we check attic and crawl-space runs that floodwater reached. If your 2017 remediation didn’t include this, we recommend a full inspection. Estimates are free - call (866) 347-2063.
Yes. We clean detached workshop units and extended duct runs on Houston acreage properties. These systems often accumulate construction dust, welding particulate, and heavy organic debris that standard residential equipment won’t extract. We bring commercial-grade Rotobrush and Nikro systems for these jobs. Call (866) 347-2063 to discuss your setup.
The most common mistake is accepting a cleaning that never inspected the attic flex duct. In Houston’s housing stock - particularly 1970s-1990s ranches - the visible registers look fine while the duct above has collapsed, separated, or molded internally from heat degradation or flood damage. A proper cleaning starts with camera inspection of the full system, not just what’s easy to reach. We do this on every job. Call (866) 347-2063 for a free estimate.
Yes. We regularly clean HVAC systems in Heights and Montrose bungalows with crawl-space duct runs. These homes present specific challenges: tight access, flood-silt residues in buried lines, and ductwork that may date to the 1980s or earlier. Our technicians are experienced with pier-and-beam construction and carry the right equipment for confined-space work. Call (866) 347-2063 to schedule.
