Fast, Reliable HVAC Cleaning Across Missouri City
HVAC cleaning in Missouri City typically costs $390-$690 for a full system, including air handler, evaporator coil, blower, and accessible supply and return runs. For homes in older sections of Missouri City like Quail Valley, expect the price to land on the higher end because those systems usually need more than a surface clean. Our crews work across Missouri City weekly and know what these homes hide in their attics. Call (806) 606-6902 and we’ll give you a written price before any panel comes off.
We’re CleanRun Air Duct Cleaning, led by Tomas Reyes, and we’ve been documenting the inside of ductwork since 2013.

Why CleanRun Air Duct Cleaning Is Missouri City’s Preferred HVAC Cleaning Company
Most homeowners in Missouri City don’t call us because their ducts feel dusty. They call because a home inspector flagged something, or an AC tech said “you need to see this,” or they’ve lived in a Quail Valley home long enough to notice the musty smell that comes back every summer. That’s the work we’re built for.
Every job starts with a written price, delivered before work begins. That’s Haven Standard Clause 1, and it exists specifically because this industry has trained Fort Bend County homeowners to expect a $79 coupon that becomes $900 on the driveway. Not here. You get a number in writing, in dollars, with a scope of work attached. If you have a competing quote, bring it. We’ll put our number next to it, in writing, at no charge. That’s our Free Second Opinion on Any Written Estimate.
When the work is done, you receive a Documented Photo Record showing the inside of every duct run, before and after. Not a summary. Not a tech’s word. Photographs of what was actually inside your system. Tomas Reyes built this practice from the first job in 2013 because he knew the only way a homeowner can verify duct cleaning is by seeing it. Across 52,000+ homes served, that record has been the deliverable that matters most.

Our HVAC Cleaning Services in Missouri City

HVAC cleaning is not one procedure. It’s a sequence of specific tasks, and in Missouri City’s housing stock, the order matters. Older Quail Valley systems need source removal at the air handler before anything else, because the blower and evaporator coil carry decades of accumulated debris that re-contaminates the ducts if left untouched.
Evaporator Coil Cleaning
The evaporator coil in a Missouri City attic air handler operates in a punishing environment. During the Gulf Coast cooling season, which runs 8-9 months here, the coil sits cold while attic air bakes at 140°F or more. That condensation cycle pulls dust, pollen, and biological material onto the coil fins. In Quail Valley homes from the late 1970s and early 1980s, we routinely find coils so matted with debris that airflow is reduced by 30-40%. Coil cleaning in Missouri City runs $180-$320 depending on access and contamination level. We photograph the coil before and after, so you can see the difference.

Blower Cleaning
The blower motor pushes every cubic foot of air your family breathes, and in older Missouri City homes, it’s pushing through a filter that may have been the wrong size for years. We find squirrel cages packed with carpet fibers, pet hair, and degraded duct liner fragments that circulated through the system. Blower cleaning in Missouri City is $140-$220, and we include static pressure readings before and after so the result is measurable, not just visible.

Condenser Cleaning
The outdoor condenser in a Missouri City yard fights pollen, grass clippings, and the fine dust that blows off the Katy Prairie. A coated condenser coil forces the compressor to run hotter and longer. Condenser cleaning is $120-$180, and we use the same coil treatment approach we use inside: clean, rinse, photograph. If your condenser sits near a construction site in the Sienna corridor, schedule it twice a year during active building.

Air Handler Cleaning
The air handler is where Missouri City HVAC systems hide their worst problems. In attic-mounted units, the drain pan, the coil, the blower housing, and the interior cabinet walls all collect what the ductwork sends back. Air handler cleaning runs $280-$450 for a full service including evaporator coil, blower motor, drain pan, and cabinet interior. For Quail Valley homes, this is the sub-service we recommend starting with, because a clean air handler makes every downstream fix more effective. Our crew uses professional-grade equipment from Abatement Technologies and Rotobrush to remove debris under negative pressure, so what’s lifted out doesn’t resettle in your hallway.

We maintain and clean systems built around Honeywell controls, Aprilaire filtration, and Guardsman purification units. If your Missouri City home has a whole-house Aprilaire filter cabinet or a UV system integrated at the air handler, we’ll inspect it during the cleaning and tell you plainly whether it’s doing its job. We don’t sell replacements unless the existing equipment is failing. HVAC Cleaning is what we do, and part of that work is making sure the components attached to your system aren’t undermining the air you’re paying to condition.
Common HVAC Cleaning Problems We See in Missouri City Homes

- Disconnected flex duct joints in Quail Valley attics. Fort Bend County’s black clay soil shrinks and swells with every rain and drought cycle. That movement transfers to the foundation, which shifts enough over forty years to pull flex duct inner liners off their collars at wye joints and register boxes. The result is conditioned air leaking into a 140°F attic while attic dust gets pulled into the system. Cleaning alone won’t fix this.
- Delaminated fiberglass duct liners shedding into the airstream. In 1970s and early 1980s Missouri City homes, we regularly find the original fiberglass liner inside flex duct has baked brittle under decades of attic heat. The liner cracks, flakes, and sends fragments through the supply registers. This is not something cleaning removes permanently; it’s something camera inspection identifies, so you can decide about repair or replacement with full information.
- Recontamination from skipped source removal. If a crew brushes the ducts but never opens the air handler, the blower and coil release debris back into freshly cleaned runs within weeks. In Lake Olympia homes with high occupancy, this is the number one reason we get called after another company has been through. The ducts looked clean for about a month.
- Crimped and crushed flex duct under attic storage. Missouri City homeowners use attic space for storage, and boxes crush duct runs. A 30% reduction in duct diameter at a single crimp point can starve the farthest bedroom of airflow. We find this constantly in mid-90s homes along the Highway 6 corridor. The fix is sometimes as simple as re-rounding the run, sometimes a section replacement.
Pricing for HVAC Cleaning in Missouri City, TX
Here are honest, written ranges for Missouri City. A single air handler with evaporator coil and blower cleaning runs $390-$540. Adding full duct cleaning for a typical 2,000-2,600 square foot Fort Bend County home brings the total to $550-$690. Homes in Quail Valley with original flex duct often need replacement sections or sealing work identified during the clean, which adds $180-$420 depending on what the camera finds. We give you the number before any work starts, and the number doesn’t change unless you approve additional scope in writing. That’s Haven Standard Clause 1.

FAQs - HVAC Cleaning in Missouri City

Because the flex duct systems installed in Quail Valley during that era were never designed to last 45+ years, and Fort Bend County’s expansive clay soil has spent those decades pulling their joints apart. Standard duct cleaning removes debris from inside the ducts but does not identify disconnected runs, crushed sections, or delaminated liners. In these homes, we do camera inspection first, because the real problem is often structural, not just dirty.
The same shrink-swell cycle that cracks your driveway and shifts your slab also moves the support structures in your attic. Flex duct runs attached to ceiling joists get pulled, crimped, and separated as the framing shifts seasonally. That introduces gaps where 140°F attic air enters the system, bakes the duct liner, and pulls unconditioned air into your supply stream. The fix is sealing work, not just cleaning. Call (806) 606-6902 and we’ll show you what the camera sees before recommending anything.
No. Cleaning removes loose debris. It cannot restore fiberglass that has delaminated from the flex duct inner wall. If the camera inspection shows active liner shedding, we’ll document it, explain what replacement would involve, and give you a written number for the repair scope. We don’t clean and walk away pretending the problem is solved.
Most often, the air handler wasn’t cleaned at the same time as the ducts. The blower and evaporator coil hold a reservoir of debris that re-contaminates the system once air movement resumes. We’ve seen this repeatedly in Lake Olympia homes where a previous company brushed the ducts but never opened the air handler cabinet. Our process always includes source removal at the air handler, blower, and coil. Call (806) 606-6902 for a written price that covers the whole system, not just the runs.
Brushing agitates debris but often leaves it in place to resettle. Source removal uses negative pressure, meaning we create airflow that pulls loosened debris out of the system through a HEPA-filtered collection unit rather than pushing it around. In Missouri City attics with degraded duct liner, source removal is the only method that actually extracts the material. We use Rotobrush and Abatement Technologies equipment for this, and we document the result before and after with photographs.
What We Actually Find in Missouri City Attics
We want to be plain about this because it’s the reason our pages read differently than anyone else’s. In Missouri City’s Quail Valley, the original 1970s flex duct systems are failing from the inside out. Fort Bend County’s expansive black clay shifts foundations year-round, disconnecting or crimping attic duct joints and letting 140°F attic air infiltrate, which bakes fiberglass liners until they delaminate and shed particles into the airstream. This is not a hypothetical or a scare story. It’s what our cameras show on a typical week.
On a Quail Valley call near Glenn Lakes Lane, our crew found a 1982-era flex duct run completely separated at a wye joint. The foundation had shifted enough over forty years to pull the inner liner off the collar, and the attic heat had baked the exposed fiberglass into a crumbling mess. We used camera inspection to map the disconnected sections, then negative pressure with a Rotobrush system to remove the loose debris, followed by source removal to clear the blower motor and evaporator coil. After resealing the joints with mastic and replacing the degraded liner with new R-8 flex, the system’s static pressure dropped and the supply registers finally delivered clean, cool air without the musty attic smell. That is the difference between a duct cleaning and a duct system correction. We do the second one.
If you live in Missouri City and your home is 20, 30, or 40 years old, the question isn’t whether your ducts are dirty. It’s what else is wrong in there. Call (806) 606-6902 and we’ll answer it with photographs, a written scope, and a number you can hold us to. You’ll get the Documented Photo Record whether you hire us for the full job or not. That’s been our practice since 2013.
