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.

AfterFast, Reliable HVAC Cleaning Across Denton
HVAC cleaning in Denton typically runs $425-$760 for a full system clean on a single-unit home, and most jobs are completed in 3-5 hours. That gets you source removal on the supply and return duct runs, the air handler, the evaporator coil, and the blower assembly. The price you pay here should buy a written scope and a photo record of the inside of your ducts, not just a van in the driveway. If you’re calling around Denton, ask any company one question before you book: will you photograph the inside of every duct run before and after? We do that on every job, and we have since 2013. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is Denton’s Preferred HVAC Cleaning Company
Denton is a two-market town. East of Bell Avenue and around the UNT and Texas Woman’s University campuses, you have high-turnover rental stock built in the 1960s through 1980s, much of it with original flexible duct that has never been inspected. South and east toward Corinth, you have new construction where builders ran the HVAC system during drywall and trim-out, loading brand-new ducts with gypsum dust and insulation fibers before the first owner ever got the keys. Both conditions require a different cleaning approach, and both show up on our camera inspections here more than almost any city in the DFW metro. Our HVAC Cleaning crews work in Denton weekly, and Tomas Reyes, who leads CleanRun, built our process around one rule: written price first, photo record last.
We’re not the cheapest quote you’ll get in Denton. We’re the company that hands you a documented record of what was in your ducts and what they look like when we finish. That difference matters in a market where $79 coupons and shop-vac specials are common. Our technicians are background-checked and uniformed, and every job carries the 365-Day Done Right Promise in writing. If it’s not right, we make it right. That’s Haven Standard Clause 5, and it’s printed on every work order we issue in Denton.
Our HVAC Cleaning Services in Denton
Evaporator Coil Cleaning
Your evaporator coil sits inside the air handler and is the component most exposed to the dust that Denton’s dry northwest winds push through older window frames and foundation cracks. When the coil’s fins are packed with compressed dust and pet hair, the system can’t transfer heat efficiently, and your AC runs longer to hit the same setpoint. In campus-adjacent rentals near UNT, we commonly find coils so fouled that airflow across them is reduced by half, and the tenant has been paying the landlord’s electric bill for a system that’s working twice as hard. We clean coils with a commercial-grade cleaning solution and rinse them in place, then photograph the coil before and after so you can see the difference. A neglected evaporator coil in a Denton home with high cooling-season runtimes from April through October is a direct drain on your monthly bill.
Blower Cleaning
The blower wheel is the fan that pushes air through your ducts. In Denton’s older homes, particularly those built before 1990, blower wheels accumulate a baked-on layer of dust and grease that reduces airflow at the source. That means less air reaches your registers even if the ducts themselves are clean. We remove the blower assembly, clean the wheel fins, and photograph the result before we reinstall it. In the new-construction neighborhoods south toward Corinth, we often find blower wheels coated in drywall dust from the build-out, which is exactly what happens when a builder runs the HVAC system during sheetrock work. A clean blower wheel in a system with clean ducts can often deliver a measurable improvement in airflow to rooms that have always felt stuffy.
Condenser Cleaning
The condenser is the unit outside your home. Denton’s location where the Cross Timbers meets the Blackland Prairie means your outdoor unit deals with the same farmland dust and pollen that covers your car. Cottonwood and ragweed in spring, harvest dust in late summer and fall, and a cooling season that stretches seven months long all mean your condenser coil is working under constant particulate load. We clean the condenser coil with a soft-wash process that removes the surface load without bending the fins, and we check the pad for level, the disconnect for signs of overheating, and the refrigerant line for damage. A clogged condenser makes the whole system run hot, and in a Denton summer that’s a strain no coil treatment alone can fix.
Air Handler Cleaning
The air handler is the box that holds the blower, the evaporator coil, and often the filter. In Denton’s older rental stock, air handlers are frequently located in attics where the access panel has been left off or poorly sealed, and that gap pulls in whatever the attic has to offer: fiberglass insulation, rodent droppings, dust from the roof deck, and hot air. A proper air handler cleaning includes full removal of loose debris from the cabinet, cleaning of the condensate pan and drain line, and a check of the drain to prevent a pan overflow. In student rentals near the UNT campus, we routinely find drain lines that have never been cleared, and pans that have been holding water long enough to support biological growth. That growth then cycles into the supply air every time the fan runs.

BeforeAfterTrusted Brands We Service in Denton
We work on systems from every major manufacturer, and we stock replacement filters and common consumable parts for Honeywell and Aprilaire systems specifically, because those brands are prevalent in Denton’s new-construction subdivisions. Most filter and media replacements can be completed same-visit without a second trip. Our cleaning equipment includes professional-grade negative-pressure extraction units and HEPA-filtered capture systems from Abatement Technologies and Nikro, which means the debris we dislodge is extracted from the home and captured, not redistributed into your living room. If you want to verify the equipment before you book, ask us when you call (806) 606-6902, and we’ll tell you exactly what we’re bringing to your home.
Common HVAC Cleaning Problems We See in Denton Homes
- Kinked or collapsed flexible duct runs. In 1960s-1980s homes near UNT and Texas Woman’s University, years of deferred maintenance and heat degradation cause flex duct to kink at elbows or slip off boot connections entirely. The system then pulls attic air, insulation fibers, and rodent debris through the duct run and into the bedrooms. A camera inspection shows this in minutes; a rotary brush cleaning that skips inspection makes it worse.
- Construction-fouled systems in new builds. In the new subdivisions pushing south and east toward Corinth, we see brand-new HVAC systems that ran during drywall installation and trim-out, coating the blower wheel, evaporator coil, and the full duct network with gypsum dust and fiberglass particles. The homeowner inherits a duct system that was contaminated before the first move-in day.
- Compacted dust layers from farmland exposure. Denton’s agricultural surroundings and dry northwest winds deposit particulate matter at rates well above what similar-age homes in Flower Mound or Lewisville experience. The dust compacts along the bottom of duct runs because the airflow carries it until velocity drops, then it settles. Over years, that compacted layer can reduce the effective cross-section of a duct run by a third or more.
- Biological growth in evaporator coils. High cooling-season runtimes and high humidity combine in Denton to keep evaporator coils wet for months at a time. In systems that haven’t been cleaned, that wet coil surface traps dust and provides a substrate for microbial growth, and the musty smell rides the supply air throughout the house.
Pricing for HVAC Cleaning in Denton, TX
A full HVAC cleaning for a single-unit home in Denton generally runs $425-$760. The price at the high end reflects a home with multiple systems, a crawlspace or attic air handler that requires more access work, or duct runs that have never been cleaned and carry heavy debris loads. The price at the low end assumes a system in good condition with standard access. Here’s what that range looks like in practice:
- Air handler cleaning (includes blower wheel, evaporator coil, condensate pan and drain line): $195-$320
- Full supply and return duct cleaning with negative-pressure extraction and HEPA capture: $230-$440
- Condenser coil cleaning: $75-$125
- Coil treatment after cleaning: included with evaporator coil cleaning

FAQs - HVAC Cleaning in Denton
Because Denton has a density of 1960s-1980s rental housing near two universities that Flower Mound and Frisco simply don’t have. Those older systems, combined with years of tenant turnover and deferred landlord maintenance, create duct conditions that newer, single-owner suburban homes rarely experience. Flower Mound and Frisco homes are largely newer construction with cleaner duct systems from day one. Denton’s housing stock is split between that neglected older rental inventory and new builds that were contaminated during construction, which means both ends of the age spectrum here carry more particulate and debris than comparably aged homes in other cities. If your Denton home was built before 1990 or purchased after 2015 as a former rental, a camera inspection of your ducts is worth doing. Call (806) 606-6902 for a written quote.
No. A fogging sanitizer can only address what’s already been loosened and removed. If the ducts still contain years of accumulated drywall dust, attic insulation, and rodent debris, fogging won’t remove any of it. The sanitizer circulates through the system and may reduce some suspended microbial load, but it doesn’t extract the physical debris that’s been sitting in the duct run for years. We use fogging as a final step on systems that have already had source removal done, because that’s the only context where it can be useful. On a neglected UNT-area rental duct system, a fogging-only job is a maintenance visit with a visible price tag and no visible result. A proper cleaning on those systems means removal first. Call (806) 606-6902 for a written scope before any work begins.
Disconnected or partially collapsed flexible duct runs at the boot connections. We pulled a partially collapsed original flexible duct from a 1970s rental near UNT that had been running disconnected at the boot connection for years, pulling conditioned air from the attic and blowing insulation fibers and dust into the bedrooms. After reconnecting the run and performing source removal with negative pressure and HEPA filtration, we sealed the supply and return ducts and treated the evaporator coil. The tenant told us the musty smell and constant dust on her dresser disappeared within a week. That condition is not rare in Denton’s campus-adjacent rental stock. It’s a systemic failure of deferred maintenance, and it means the tenant has been paying to partially cool and heat the attic while breathing attic air. A camera inspection before any cleaning shows whether your system has these failures. Call (806) 606-6902 to schedule one.
Because builders routinely run the HVAC system during drywall installation and interior trim-out. That practice pulls gypsum dust, sawdust, and fiberglass insulation particles into the return ducts, where they settle on the blower wheel, evaporator coil, and along the supply runs. The homeowner moves in and assumes a new system is a clean system. It’s not. We’ve documented this in new subdivisions south and east of Denton toward Corinth, where the first cleaning a home ever gets often finds a full layer of construction dust coating the inside of the supply plenum and the blower assembly. If you bought a new-construction home in Denton and have never had the ducts inspected, the odds are high that you’ve been circulating drywall dust since the day you moved in. Call (806) 606-6902 for a written price on a full system inspection and cleaning.
Yes. Denton sits where the Cross Timbers meets the Blackland Prairie, and the surrounding cultivated farmland produces heavy dust loading during dry northwest winds. That means your HVAC system’s filter is working against a higher particulate load than a comparable home in an urban or coastal climate, and the dust that bypasses the filter settles in the duct runs faster. We see systems in Denton with predictable dust accumulation patterns that match the prevailing wind direction, with the return side loading faster than the supply side. That means a Denton home’s ducts will typically reach a given level of contamination in fewer years than the same system in Lewisville or Frisco. If your filter is visibly loaded every 30 days, the ducts are almost certainly carrying more than they should. Call (806) 606-6902 for a written price and a documented photo record of what’s actually in your ducts.
