Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning in Missouri City, TX
Complete HVAC Cleaning in Missouri City typically runs $380-$650 for a whole-system job, with Air Quality & Sanitizing add-ons ranging $150-$400 depending on whether we’re treating mold inside flex duct runs or installing UV lights at the air handler. We’re CleanRun Duct Repair & Cleaning, and our crews work Missouri City’s master-planned communities weekly - Sienna Plantation, Lake Olympia, Colony Meadows, Quail Valley - on homes whose attic-mounted flex duct systems have spent 20-30 years in 140°F summer attics. Every job starts with a written price before any panel comes off, and every duct run is photographed before and after. Call (346) 421-3357 for a free estimate.
Why Missouri City Homes Are Different
Missouri City’s building boom between 1990 and 2010 - Sienna Plantation, Lake Olympia, Colony Meadows - filled the area with brick-veneer, slab-on-grade tract homes whose flex duct runs sit in vented attics that hit 140°F or higher from May through September. That sustained heat degrades duct liner adhesive, creates gaps at elbows and plenum connections, and lets attic debris and humid Gulf Coast air infiltrate the supply stream.
The floodplain geography compounds this. Portions of Quail Valley and Lake Olympia sit near Oyster Creek, and Hurricane Harvey pushed water through low-set floor vents and return grilles into duct systems that were never properly dried. We regularly find active mold colonies inside flex duct runs in homes where visible water damage was repaired years ago but the attic ductwork was never inspected. Missouri City’s 70%+ year-round humidity means any moisture intrusion promotes microbial growth before homeowners notice musty odors or respiratory symptoms.
Two-story layouts common in Sienna Plantation produce long, branching flex duct runs with multiple elbows - more access points needed, more debris accumulation, and more places for liner degradation to create leaks. Quail Valley’s 1970s-era homes may be on original or first-replacement duct systems at or past the 20-25 year service life, with metal duct transitions showing corrosion that newer communities haven’t reached yet.
Our Main Missouri City Services
These are the three services Missouri City homeowners call us about most often. Each has its own dedicated page with full pricing and scope details.
Air Duct Cleaning in Missouri City
We clean the full supply and return network - every duct run, register, and the main trunk line - using negative-pressure extraction (a vacuum system that pulls debris out while agitation tools loosen it from duct walls). In Missouri City, we pay particular attention to flex duct elbows where attic heat has degraded the liner, and we photograph every run before and after so you can see what came out.

Dryer Vent Cleaning in Missouri City
Lint accumulation in dryer vents is a fire hazard and efficiency killer. We clean the full vent run from the back of the dryer to the exterior termination, using rotary brushes and high-velocity air tools. Missouri City’s humidity means lint clumps more readily than in drier climates, and longer vent runs in two-story Sienna Plantation homes create more resistance and faster buildup.

Duct Repair & Sealing in Missouri City
When flex duct liner has degraded past cleaning, or when Harvey flood damage left gaps and corrosion in metal transitions, we repair or replace the affected sections and seal the entire system with mastic or foil tape rated for attic temperatures. Every repair is photographed, priced in writing before work starts, and backed by our 365-Day Done Right Promise. Duct Repair & Sealing in Missouri City

Before
AfterHVAC Cleaning in Missouri City

HVAC Cleaning in Missouri City addresses the components your air passes through after it leaves the ductwork - the evaporator coil, blower, condenser, and air handler - where Gulf Coast humidity and continuous eight-to-nine-month cooling seasons create a unique maintenance burden. In Sienna Plantation and Lake Olympia homes, we regularly find evaporator coils coated with a paste of pollen, mold spores, and fine dust that reduces airflow and forces the compressor to run longer, driving up electric bills during Houston’s brutal summer peaks. HVAC Cleaning is documented with the same before-and-after photo record as our duct work, and priced in writing before we touch a single panel.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the refrigerant lines, weak airflow from registers, or a musty smell when the AC first cycles on - all point to a coil choked with microbial growth and debris.
What it costs in Missouri City
Evaporator coil cleaning in Missouri City typically ranges $180-$320 for accessible attic-mounted systems, with prices at the higher end when the coil requires removal for cleaning or when flood-damaged drain pans need replacement.
How we do it
We access the coil through the plenum (the sheet-metal box that distributes air from the air handler), apply foaming cleaner that breaks down biological growth without damaging aluminum fins, rinse with low-pressure water, and photograph the coil before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler cabinet, uneven airflow between rooms, or dust puffing from registers when the system starts indicate a blower wheel coated with debris.
What it costs in Missouri City
Blower cleaning runs $150-$280 in Missouri City, with two-story homes in Sienna Plantation sometimes requiring additional access time due to cramped attic layouts.
How we do it
We remove the blower assembly, clean the squirrel-cage wheel and motor housing with compressed air and solvent, balance the assembly, and reinstall with new mounting hardware if the original fasteners show corrosion from attic humidity.
What HVAC Cleaning Costs in Missouri City
| Item | Typical range in Missouri City |
|---|---|
| Evaporator coil cleaning | $180 - $320 |
| Blower cleaning | $150 - $280 |
| Condenser cleaning | $120 - $220 |
| Full HVAC system cleaning (coil + blower + condenser) | $380 - $650 |
How do I know if my HVAC needs cleaning or just my ducts?
If you see dust at registers but airflow feels normal, start with duct cleaning; if airflow is weak, rooms cool unevenly, or you smell mustiness when the AC cycles, the HVAC components need attention - we inspect both and show you photos before recommending scope. Call (346) 421-3357 and we’ll put both options in writing.
Can HVAC cleaning reduce my summer electric bill?
Yes - a clean evaporator coil and blower move air efficiently, so the compressor runs less; in Missouri City’s eight-month cooling season, that difference adds up, especially in older Sienna Plantation homes where systems already work harder to push air through long duct runs. We’ll show you the before photo so you can judge the improvement yourself.
Air Quality & Sanitizing in Missouri City

Air Quality & Sanitizing in Missouri City targets the microbial aftermath of our local climate and flood history - mold colonies inside flex duct runs from Harvey moisture that never dried, bacteria thriving in humid attic air handlers, and the persistent musty odors that standard cleaning won’t remove. In Quail Valley and Lake Olympia homes near Oyster Creek’s floodplain, we regularly treat duct systems where visible water damage was repaired years ago but the interior lining harbors active growth that spores into living spaces every time the AC cycles. Air Quality & Sanitizing is always scoped and priced in writing before application, with post-treatment photos to verify results.
Mold Treatment
Signs you need it
Musty odors that return within days of duct cleaning, visible mold around registers, or family members with unexplained respiratory symptoms that worsen when the AC runs.
What it costs in Missouri City
Mold treatment for a whole duct system in Missouri City typically ranges $350-$650, with Harvey-impacted homes in floodplain neighborhoods sometimes requiring multiple access points and extended drying time.
How we do it
We apply an EPA-registered fungistatic treatment throughout the duct network using a fogging system that reaches past the first elbow, then seal the system and run the air handler to distribute the product evenly, photographing every treated run.
UV Light Installation
Signs you need it
Recurring mold despite previous treatments, or a home in a high-humidity area where you want continuous prevention rather than periodic remediation.
What it costs in Missouri City
UV light installation at the air handler in Missouri City runs $280-$450 for a single-lamp system, with dual-lamp configurations for larger Sienna Plantation homes at the higher end.
How we do it
We mount a UV-C lamp in the supply plenum where it irradiates the coil and immediate airflow, wire it to the air handler’s 24-volt circuit so it cycles with the system, and show you the installation photo as part of your job record.
What Air Quality & Sanitizing Costs in Missouri City
| Item | Typical range in Missouri City |
|---|---|
| Mold treatment (whole system) | $350 - $650 |
| Bacteria sanitizing | $150 - $300 |
| UV light installation (single lamp) | $280 - $450 |
| Air purifier install (whole-house) | $400 - $850 |
Is mold treatment safe for kids and pets?
Yes - we use EPA-registered products applied when the home is unoccupied, with a two-hour re-entry window and ventilation period; we document the product label and application time in your written job record for your reference. Call (346) 421-3357 to schedule around your family’s schedule.
How long does UV light installation take?
Most UV installations in Missouri City take 90 minutes to two hours, including mounting the lamp in the plenum, wiring to the air handler, and testing the cycle - we photograph the installed unit and show you the switch location before we leave. Written price confirmed before we start, as with every CleanRun job.
