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.

AfterAir Duct Cleaning in Sugar Land, TX
Complete HVAC cleaning in Sugar Land typically runs $380-$680 for a whole-house system, with air quality and sanitizing treatments adding $220-$450 depending on the scope. The combination of 150°F+ attic temperatures and year-round Gulf Coast humidity in Sugar Land’s master-planned communities creates conditions we don’t see in drier Texas markets. Call (346) 253-1822 for a written estimate before any work starts.
CleanRun crews coordinate dispatch from our Houston office and serve Sugar Land homes with the same documented approach we’ve used since 2013: written price first, then a photo record of every duct run before and after. The H.A.V.E.N. Standard governs every visit.
Why Sugar Land Homes Are Different
Sugar Land’s master-planned communities - First Colony, Telfair, New Territory, and Riverstone - were built predominantly between 1990 and 2015 with large two-story brick homes whose builder-grade flex duct systems run almost entirely through unconditioned attics. Those attics routinely hit 150°F+ during the six-month cooling season, degrading flex duct inner liners while the city’s persistently high Gulf Coast humidity, averaging roughly 74% RH year-round, creates ideal conditions for mold colonization inside ducts whenever the A/C cycles off.
In the earliest First Colony subdivisions, we regularly find original flex duct whose mylar inner liner has gone brittle from decades of extreme attic heat. Fort Bend County’s expansive black clay soil causes enough seasonal foundation movement to pull flex duct boot connections partially loose, so a cleaning call often reveals both contaminated ducts and significant air-loss leaks at the register connections. Even mid-2000s builds in New Territory and Telfair are now 15-20 years old, the point where inner duct liners begin to crack and debris accumulation becomes significant.
Our Main Sugar Land Services
Most Sugar Land homeowners who call CleanRun start with one of these three services:
Air Duct Cleaning in Sugar Land
We clean the complete duct network - supply and return runs, plenum, and registers - using negative-pressure extraction with Rotobrush and Nikro equipment. In Sugar Land, this almost always means addressing humidity-driven debris buildup in flex duct routed through super-heated attics, plus photographing every run before and after so you can see what came out. Air Duct Cleaning in Sugar Land includes our standard documented photo record and written price before work begins.
Dryer Vent Cleaning in Sugar Land
Dryer vent blockages are common in Sugar Land’s larger homes with longer vent runs through exterior brick walls. We clear the full vent path from appliance to termination, measure airflow before and after, and flag any flex-duct transitions that violate current fire-safety standards. Dryer Vent Cleaning in Sugar Land carries the same written-price guarantee and photo documentation.
Duct Repair & Sealing in Sugar Land
Foundation movement in Fort Bend County separates flex duct boots from registers, and brittle attic-aged liners crack rather than clean. We repair separations with mechanical fasteners and sealed collars, replace damaged flex sections, and pressure-test the system afterward. Duct Repair & Sealing in Sugar Land is quoted as a flat price per system, not per vent.

BeforeAfterHVAC Cleaning in Sugar Land
HVAC cleaning in Sugar Land addresses the components the ducts connect to - coils, blowers, air handlers - where Gulf Coast humidity and near-continuous cooling-season operation create biological growth and efficiency losses we rarely see in drier climates. A typical Sugar Land system runs hard from March through November, and the evaporator coil in particular becomes a condensation collection point that feeds mold and restricts airflow. HVAC Cleaning from CleanRun includes full photo documentation and a written price before any panel comes off.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odors when the compressor cycles on.
What it costs in Sugar Land
Evaporator coil cleaning in Sugar Land typically runs $180-$320 for accessible A-coils in attic air handlers.
How we do it
We remove the access panel, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water capture, and photograph the coil condition before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust streaking from supply registers.
What it costs in Sugar Land
Blower assembly cleaning in Sugar Land generally falls between $150-$280 depending on access and contamination level.
How we do it
We remove the blower wheel and housing, clean blades and motor housing with compressed air and solvent, balance the assembly, and document RPM and amp draw before reassembly.
What HVAC Cleaning Costs in Sugar Land
| Item | Typical range in Sugar Land |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower assembly cleaning | $150-$280 |
| Full HVAC cleaning (coil + blower + cabinet) | $380-$680 |
How do I know my HVAC components need cleaning, not just the ducts?
If you smell musty air when the compressor starts, see ice on refrigerant lines, or notice weak airflow despite clean filters, the problem is likely in the coil or blower, not the ductwork. Call (346) 253-1822 and we’ll inspect both - estimates are free.
Can HVAC cleaning improve my cooling bills in Sugar Land?
Yes - a dirty evaporator coil can drop system efficiency 15-30%, and in Sugar Land’s six-month cooling season that adds up fast. We measure static pressure before and after so you can see the improvement in writing.
Air Quality & Sanitizing in Sugar Land
Air quality and sanitizing in Sugar Land targets the biological growth that Gulf Coast humidity breeds inside duct systems - mold, bacteria, and the persistent musty odors that return even after cleaning. The combination of 74% average relative humidity and 150°F attic temperatures creates a cycle where condensation forms on duct interiors when large systems cycle off overnight, directly feeding mold and mildew that standard vacuum extraction cannot address. Air Quality & Sanitizing from CleanRun applies EPA-registered treatments with documented before-and-after photo verification.
Mold Treatment
Signs you need it
Visible black or green growth at registers, musty odors that intensify when the A/C first cycles on, or family members with unexplained respiratory irritation.
What it costs in Sugar Land
Mold treatment for a typical Sugar Land whole-house system runs $280-$520 depending on contamination extent and accessibility.
How we do it
We apply an EPA-registered botanical fungistat to all interior duct surfaces using mechanical fogging, allow proper dwell time, then verify treatment coverage with UV flashlight inspection and photograph every treated run.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic musty odors, or a household with allergy or asthma concerns.
What it costs in Sugar Land
UV-C light installation in Sugar Land typically costs $320-$580 for a properly sized lamp assembly with ballast and mounting hardware.
How we do it
We mount a 254nm UV-C lamp downstream of the evaporator coil with a sight-glass port for annual inspection, wire to the blower circuit for automatic operation, and include the lamp in our annual maintenance reminder.
What Air Quality & Sanitizing Costs in Sugar Land
| Item | Typical range in Sugar Land |
|---|---|
| Mold treatment (whole system) | $280-$520 |
| Bacteria sanitizing | $220-$380 |
| UV-C light installation | $320-$580 |
Is mold in ducts common in Sugar Land specifically?
Yes - the combination of high humidity and attic temperatures that spike when systems cycle off creates condensation inside ducts that we don’t see in drier Texas markets. We find active growth in roughly half of Sugar Land homes over 15 years old.
Will sanitizing treatments leave chemicals in my air?
No - we use EPA-registered botanical formulations with no residual VOCs, and we run the system for 30 minutes post-treatment with windows open to clear any transient odor. The photo record shows treated surfaces, not airborne product.
Brands We Service in Sugar Land
We stock parts and service equipment from Honeywell, Aprilaire, and Guardsman, with common filters, UV lamps, and media pads available without ordering delay. Most Sugar Land homes with these brands see same-visit completion for standard maintenance. See our brands for the full roster.
