Fast, Reliable HVAC Cleaning Across Greatwood
We’re Bellows Air Duct & Vent Co., and we’ve been driving out to Greatwood since the neighborhood was still filling in with new construction. These days we’re on Greatwood Parkway and FM 723 a few times a week, usually arriving within 45 minutes of a call from anywhere in the 77469 ZIP. Greatwood’s homes - mostly built between 1988 and 2005 - are hitting that age where their original flex-duct systems need more than a filter change. If your vents are pushing musty air, your evaporator coil is icing over, or your blower’s working harder than it should, call us at (866) 347-2063. We’ll show you exactly what’s inside your ducts before we touch a thing.

Our HVAC Cleaning Services in Greatwood
Evaporator Coil Cleaning
In Greatwood’s humidity - routinely 70-80% relative humidity year-round - evaporator coils work overtime and collect biofilm fast. A dirty coil in a Greatwood attic forces your compressor to run longer, raises your electric bill, and can’t dehumidify properly. We remove the coil assembly when accessible, clean with foaming agents safe for aluminum fins, and verify airflow improvement with before-and-after readings. Coil cleaning runs $180-$340 for most Greatwood homes.
Coil Treatment
After cleaning, we apply an antimicrobial treatment to the evaporator coil and drain pan. In Greatwood, where systems run 9-10 months annually, this treatment prevents rapid regrowth of mold and bacteria. For homes near Lake Olympia or other low-lying areas that saw flood exposure, this step is particularly important. Coil treatment as an add-on is $85-$140.
Blower Cleaning
The blower wheel in your air handler catches dust, pet hair, and construction debris from two decades of circulation. In Greatwood’s older flex-duct systems, blower contamination is often worse because sagging return ducts pull attic air past compromised joints. We remove and clean the blower assembly, balance the wheel, and check motor amp draw. Most blower cleanings in Greatwood fall between $220-$380.
Condenser Cleaning
Your outdoor condenser coil faces pollen, cottonwood fluff, and lawn debris across Fort Bend County’s long cooling season. A clogged condenser raises head pressure and shortens compressor life. We clean coils with foaming cleaner and low-pressure water, straighten damaged fins, and check refrigerant levels. Condenser cleaning typically costs $150-$280 in Greatwood.
Air Handler Cleaning
The air handler cabinet houses your blower, coil, and drain system. In Greatwood homes with 20-35-year-old flex ducts, we often find standing water in the cabinet from backed-up condensate lines or leaking plenums. We clean and sanitize the entire cabinet, clear drains, and seal leaks. Air handler cleaning ranges from $280-$520 depending on accessibility and condition.
Heat Exchanger Cleaning
For gas furnaces, a cracked or soot-clogged heat exchanger is a safety issue. We inspect with cameras and clean where accessible. If we find cracks, we stop work and advise replacement. Heat exchanger inspection and cleaning runs $200-$350.

Trusted Brands We Service in Greatwood
We clean and maintain systems from every major manufacturer, and we stock common replacement parts for Honeywell and Aprilaire components right on our trucks. That means most Greatwood jobs finish in a single visit.

If your system uses a proprietary coil design or an older blower assembly, we’ll tell you before we start whether parts are available or if a retrofit makes more sense.
Common HVAC Cleaning Problems We See in Greatwood Homes
- Hidden mold in Harvey-exposed flex ducts. In the Greatwood neighborhood near Lake Olympia, we cleaned a 1998 flex-duct system in a slab-on-grade home that had flooded during Harvey. The owner reported a musty smell during humid months, and our Rotobrush inspection revealed mold embedded in the inner liner despite no visible growth. We applied an Abatement Technologies antimicrobial treatment and sealed the duct joints to reduce ongoing condensation risk.
- Sagging flex-duct joints creating condensation traps. Greatwood’s 20-35-year-old flex ducts sag at joints and low points, especially in attics that reach 140°F in summer. Condensation pools in these dips, fostering microbial growth even in homes that never flooded.
- Surface-only cleaning that misses embedded contamination. Technicians using only visual wipe-downs or basic vacuuming fail to address mold embedded in duct liner fabric. The musty smell returns within months, and homeowners assume the problem is elsewhere.
- Evaporator coils choked with biofilm from constant operation. Greatwood systems run most of the year. Without regular cleaning, coils become coated with a layer of biological material that reduces heat transfer and breeds odors.

FAQs - HVAC Cleaning in Greatwood
Yes, there can be. If the HVAC system was running during or soon after flooding, mold spores may have entered the air handler, evaporator coil, and blower assembly - components that weren’t always replaced when ducts were. We camera-inspect these areas and can test liner remnants if any original flex duct remains. Call (866) 347-2063 for a free inspection.
Every 2-3 years for the full system, with evaporator coil cleaning annually if you run cooling heavily. Greatwood’s 70-80% humidity and 9-10 month cooling season accelerate biofilm growth on coils and condensation in ducts. Homes near the Brazos River lowlands or with known Harvey exposure should consider more frequent inspection. Call us to set a schedule that fits your home.
They require more careful cleaning, yes. Flex ducts from the 1988-2005 building era have inner liners that deteriorate with age. Aggressive cleaning can damage them further. Our Rotobrush equipment is adjustable for older liner materials, and we inspect with cameras to assess liner condition before proceeding. This is standard on every Greatwood job we take.
Very likely. Systems restored too quickly after 2017 flooding often pulled moisture and mold spores through ductwork that was patched rather than fully remediated. The contamination embeds in flex-duct liner fabric and isn’t visible from the outside. Our camera inspection reveals what standard cleaning misses. Call (866) 347-2063 - estimates are free.
Yes, especially in Greatwood. The coil is where moisture condenses and microbial growth concentrates. Cleaning ducts without addressing a contaminated coil means your clean ducts immediately recirculate coil-borne spores. We bundle coil cleaning with duct service at reduced rates, and the improvement in airflow and odor is significant. Ask about package pricing when you call.
