HVAC cleaning in Missouri City typically runs $180-$450 depending on which components need attention, and most jobs are completed in a single visit.

Call (844) 685-6342 for upfront pricing and a free estimate - we’ll show you exactly what we find before any work begins.
Our HVAC Cleaning team has been serving Fort Bend County homeowners for over 42 years. We understand that in Missouri City, your system isn’t just dirty - it’s fighting against coastal humidity, clay soil moisture, and in many neighborhoods, the lingering effects of a storm that hit seven years ago but never really left the ductwork.
Why Bellows Air Duct & Vent Co. Is Missouri City’s Preferred HVAC Cleaning Company
Missouri City homeowners know the difference between a company that shows up and one that shows up prepared. We’ve built our reputation in Fort Bend County on doing the job right and backing it in writing for 90 days - no paperwork, no arguing. Our technicians are background-checked, uniformed, and equipped with camera inspection systems that let you see inside your ducts before and after we clean them.
Calls are answered by a live person, 24 hours a day. Not a voicemail tree. Not an app. When you’re dealing with musty air in a Quail Valley ranch home or weak airflow in a Sienna Plantation two-story, you want to talk to someone who can dispatch help, not record your callback number.
Our no-hassle upfront pricing means the number we give you on the phone is the number on the invoice. We’ve never used bait coupons or scare tactics, and we don’t start work until you know exactly what it costs. That’s been our practice since Ray Castillo founded Bellows Air Duct & Vent Co. in 1984.
Most Missouri City jobs are completed in one visit. We carry the equipment and parts to handle evaporator coil cleaning, blower service, condenser work, and full air handler cleaning without ordering components or scheduling return trips.
Our HVAC Cleaning Services in Missouri City
Evaporator Coil Cleaning
The evaporator coil in your Missouri City air handler is where humidity becomes a problem you can see. Coastal air loaded with moisture coats the coil with biofilm and mold, restricting airflow and forcing your compressor to run longer. In 77489-area homes with original 1980s systems, we regularly find coils so clogged that airflow has dropped by 30% or more. Our process removes the buildup without damaging delicate fins, then we verify improvement with before-and-after camera documentation.
Blower Cleaning
Your blower motor and wheel move every cubic foot of air your Missouri City home breathes. Dust and mold spores that make it past a clogged filter accumulate on the blower blades, throwing them out of balance and increasing energy draw. In Sienna Plantation homes with multi-zone systems, a dirty blower in one air handler can create pressure imbalances that affect the entire house. We remove the blower assembly, clean it thoroughly, and reinstall it with proper torque specifications.
Condenser Cleaning
Missouri City’s salt-air environment attacks outdoor condenser coils and hardware faster than inland locations. Corroded electrical connections and degraded aluminum fins reduce heat rejection capacity, which means your system runs longer to achieve the same cooling. We clean coils with foaming agents that won’t pit the metal, check fasteners for corrosion, and document any hardware that needs replacement before it fails in August heat.
Air Handler Cleaning
The air handler is where your Missouri City system’s problems often begin. In Quail Valley and other 77489 neighborhoods, we’ve opened air handlers to find black mold colonizing the interior surfaces - contamination that has been recirculating through the home since Hurricane Harvey repairs focused on visible damage and skipped the ductwork. Our air handler cleaning includes full interior disinfection, drain pan treatment, and seal inspection to prevent attic humidity from re-entering the system.
Coil Treatment
After cleaning, we apply Guardsman antimicrobial treatment to evaporator coils in Missouri City homes with a history of mold or high humidity. This isn’t a perfume mask - it’s a residual treatment that inhibits microbial regrowth on the coil surface. For post-Harvey homes where mold has established a foothold, this step is often the difference between a clean system and one that smells musty again within months.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Missouri City’s older 77489 homes require periodic inspection and cleaning to maintain safe, efficient operation. Cracks or heavy soot buildup can introduce combustion gases into your airflow. We inspect with cameras and clean according to manufacturer specifications, documenting our findings for your records.

Trusted Brands We Service in Missouri City
We clean and service systems built with equipment from Rotobrush, Abatement Technologies, Aprilaire, and other professional-grade manufacturers.

We don’t substitute generic components where specification-grade parts are called for - the hardware in your attic faces enough stress from heat and humidity without cutting corners on materials.
Common HVAC Cleaning Problems We See in Missouri City Homes
- Post-Harvey mold in flex duct: In Quail Valley and other 77489 subdivisions, we regularly find flex duct connections near the air handler colonized with black mold that was never addressed after 2017 flood repairs. Homeowners replaced drywall and flooring but left contaminated ductwork in place, and the system has been recirculating spores ever since.
- Salt-air corrosion of hardware: Missouri City’s proximity to the Gulf accelerates corrosion of ductwork fasteners, access doors, and condenser hardware. Corroded fasteners create air leaks that draw humid attic air into the supply system, causing condensation and mold conditions inside the ducts.
- Clay soil moisture elevation: The Vertisols soil throughout Missouri City holds water near slab foundations longer after rain events. This elevates indoor humidity in ranch-style homes year-round, promoting mold growth inside ducts even when outdoor conditions seem mild.
- Attic heat degradation of seals: Attic temperatures exceeding 140°F degrade mastic seals and flex duct connections over decades of exposure. In 77489’s 1970s-1980s housing stock, we find separated connections that have been leaking conditioned air into the attic for years.

FAQs - HVAC Cleaning in Missouri City
If your home flooded in 2017 and you haven’t had professional duct inspection since, schedule it now. In Quail Valley and other 77489 neighborhoods, we’ve found active mold colonies in ductwork that homeowners assumed had dried out years ago. Call (844) 685-6342 for a camera inspection - estimates are free, and we’ll show you exactly what’s inside your system.
Yes. Missouri City’s coastal-prairie humidity routinely exceeds 75-85%, and when duct seals fail even slightly, warm attic air is drawn into the supply system, creating persistent condensation and mold conditions. Our cleaning process includes seal inspection and repair recommendations specifically to address this moisture dynamic. For an assessment of your system’s humidity vulnerability, call (844) 685-6342.
In most cases, yes - significantly. We’ve measured airflow improvements of 25-40% in Missouri City homes where coils were clogged with biofilm and dust. The coil is the primary restriction point in your air handler, and in this climate, it fouls faster than in drier regions. Call (844) 685-6342 to schedule coil inspection and cleaning.
We apply Guardsman antimicrobial coil treatment after cleaning, and for severe contamination, we recommend full duct remediation with source removal using our Rotobrush system. In post-Harvey Missouri City homes, we never clean without identifying the moisture source first - treating mold without fixing the humidity problem guarantees recurrence. Call (844) 685-6342 to discuss your specific situation.
Homes in Sienna Plantation’s 77459 ZIP typically need full HVAC cleaning every 3-4 years, with annual evaporator coil inspection. The multi-zone duct layouts common in this area create more surface area for debris accumulation, and the larger homes mean longer runtime hours. If anyone in your household has allergies or you’ve noticed musty odors, annual cleaning may be warranted. Call (844) 685-6342 to set up a maintenance schedule that fits your home.
We’re ready when you are. Call Bellows Air Duct & Vent Co. at (844) 685-6342 for upfront pricing, camera-verified results, and the 90-Day Done Right Promise in writing.
