Fast, Reliable HVAC Cleaning Across Alief
HVAC cleaning in Alief typically runs $280-$580 for a complete system cleaning, and most jobs are finished in a single visit. We answer calls live, 24 hours a day, and we carry the equipment to handle Alief’s older homes without scheduling a return trip.
We’ve been driving out to Alief since 1984, back when much of this area was still new construction. Now those same neighborhoods, the ones off Boone Road and Beechnut and along Bissonnet, are pushing 50 years old. The flex duct systems installed in those attics in 1978 or 1983 weren’t designed to last half a century, and they certainly weren’t designed for Houston’s humidity cycling through them year after year. We know the route. We know the housing stock. And we know that when an Alief homeowner calls, they’ve usually been putting this off longer than they should have.
Our HVAC Cleaning team carries Rotobrush and Nikro equipment on every truck, with HEPA filtration and camera inspection capability built in. One call to (866) 347-2063 gets you a live person, a firm arrival window, and pricing before we lift a single tool.
Why Bellows Air Duct & Vent Co. of Texas Is Alief’s Preferred HVAC Cleaning Company
Forty-two years in this region means we’ve cleaned systems in Alief’s original 1970s subdivisions, its 1980s expansion phases, and the rental properties that turned over after the oil bust. We’ve seen what happens when flex duct sits in a 140-degree attic for four decades. We don’t need to guess.
Our technicians are background-checked and uniformed, and they answer to a live person at our office, not an app or a voicemail tree. That matters in Alief, where many of our customers have owned their homes for twenty-plus years and remember when a phone call got you a human being.
We complete most jobs in one visit because we stock the right equipment and the right parts. No bait coupons, no price changes when we arrive. The number we give you on the phone is the number on the invoice. That’s been our practice since 1984, and it’s not changing.
Our 90-Day Done Right Promise applies to every Alief job. If something isn’t right, we return at no charge. No paperwork to file, no arguments to have. We stand behind it.
Our HVAC Cleaning Services in Alief
Evaporator Coil Cleaning
The evaporator coil in your air handler sits in a dark, damp environment, and in Alief’s climate, that means constant biological activity. We pull the coil, inspect it with a borescope camera, and clean it with foaming agents and low-pressure rinses that won’t damage the fins. A clean coil transfers heat properly, which means your system runs less and your summer electric bills drop. In Alief’s 8-to-9-month cooling season, that adds up fast.
Blower Cleaning
The blower wheel moves every cubic foot of air through your system, and when it’s caked with dust and microbial growth, it can’t move air efficiently. We remove the blower assembly, clean it outside the unit, and balance it before reinstallation. Alief’s older homes often have blowers that have never been cleaned, which explains the weak airflow at registers and the system running constantly without cooling properly.
Condenser Cleaning
Your outdoor condenser coil rejects the heat your system pulls from your home, and when it’s clogged with cottonwood fuzz, grass clippings, or the fine grit that blows through southwest Harris County, it can’t do its job. We clean the coils, straighten damaged fins, and check refrigerant levels. In Alief, where many homes still have their original 1980s condensers, this cleaning can extend equipment life by years.
Air Handler Cleaning
The air handler is the central station of your HVAC system, and in Alief’s slab-on-grade ranches, it’s usually in a closet or the garage, drawing return air from the attic through that original flex duct. We clean the entire cabinet, the drain pan, the blower compartment, and the return plenum. For homes with post-Harvey mold concerns, this is where we find the evidence, and where our cleaning makes the most immediate difference in air quality.
Heat Exchanger Cleaning
Gas furnaces in Alief see limited winter use, but when they run, they need clean heat exchangers for safe, efficient operation. We inspect for cracks and corrosion, clean the exchanger surfaces, and verify proper draft. This is safety-critical work, and we document it with camera footage you can see.
Coil Treatment
After cleaning, we apply EPA-registered antimicrobial treatments to evaporator and condenser coils where indicated. This isn’t a substitute for physical cleaning, but it extends the results in Alief’s humid environment, where biological regrowth begins almost immediately.

Trusted Brands We Service in Alief
We clean and service equipment from Honeywell, Aprilaire, and the major HVAC manufacturers found in Alief’s housing stock. Our trucks carry Rotobrush and Nikro cleaning systems, the same equipment specified by serious commercial contractors. We don’t show up with a shop vacuum and hope for the best. For common replacement parts, we stock locally, which means if we find a failed component during cleaning, we can often replace it same-day rather than ordering and rescheduling. Alief homeowners have waited long enough for proper service. We’re not adding to the delay.
Common HVAC Cleaning Problems We See in Alief Homes
- Flood-contaminated flex duct ignored after exterior repairs. After Hurricane Harvey in 2017, many Alief homes had drywall replaced and flooring redone, but the flex duct runs that wicked up standing water through floor registers were never addressed. We’ve found active mold colonies circulating through otherwise repaired homes years later.
- Inner liner collapse in original 1970s-80s flex duct. The fiberglass liner inside old flex duct breaks down, collapses into the airstream, and creates blockages that standard filter changes never touch. Homeowners wonder why some rooms never cool properly. This is why.
- Joint separation in attic runs. After 40-50 years of thermal cycling in unconditioned Alief attics, the tape and mechanical connections at duct joints fail completely. Your AC is cooling your attic, not your bedrooms.
- Absentee-landlord deferred maintenance. A significant share of Alief’s rental stock has never had professional duct cleaning since original construction. Tenants breathe decades of accumulated particulate, and the system efficiency degrades year by year.

FAQs - HVAC Cleaning in Alief
The flexible fiberglass-lined duct installed during that construction era degrades from the inside out, particularly in unconditioned attics where Houston’s heat and humidity stress the material continuously. After 40-50 years, the inner liner collapses, joints separate, and the porous surface traps particulate that standard filters never reach. Call (866) 347-2063 and we’ll show you exactly what your system looks like inside.
Yes. Floodwater wicked up through floor registers in many Alief homes, contaminating flex duct runs that homeowners never thought to inspect. We’ve cleaned systems where mold colonies were actively circulating five years after the flood, because only the visible damage got repaired. If your home took any water at all, the ducts should be camera-inspected.
Weak airflow at specific registers, rooms that never reach set temperature, and visible dust plumes when the system cycles are common signs. We verify with borescope camera inspection, which we perform before any cleaning work. You’ll see the damage yourself before we quote any repair.
We work directly with tenants in Alief rental properties when the landlord approves, or we can provide documentation to help you make the case. Many absentee landlords simply don’t know the condition of systems they haven’t inspected in decades. Our camera footage usually gets their attention. Call (866) 347-2063 to discuss your situation.
Yes. Evaporator coil cleaning is included in our full air handler cleaning service, and we always inspect the coil condition during any HVAC cleaning visit in Alief. Dirty coils are the single biggest efficiency killer we find in older systems, and cleaning them produces immediate, measurable improvement. Call (866) 347-2063 for a free estimate.
Last spring we serviced a 1982 ranch home on Boone Road in Alief. The original flex ducts had sagged and partially detached in the attic, and after Hurricane Harvey’s floodwaters wicked up through the floor registers, we found active mold colonies in every run. We used our Rotobrush system with HEPA filtration to clean the evaporator coil and air handler, then restored the duct connections. The homeowner had lived there since 1989 and never known what was circulating above her ceiling.
That’s the pattern in Alief. The housing stock is honest and solid, but the hidden systems have been neglected for decades. We’re the company that looks where others don’t, documents what we find, and fixes it in one trip.
