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 Duncanville, TX
Dryer vent cleaning in Duncanville is a job that runs straight into the age of the housing stock. Most homes here were built between 1965 and 1985, which means the dryer vents are metal or flex runs that have been collecting lint for 40 to 60 years. The 100-degree summers don’t cause the lint problem, but they do mean dryers run constantly, and every cycle pushes more moisture and lint into a vent that may already be half closed. Call (806) 606-6902 and we’ll put a camera in the vent before we touch anything, so you can see what we see.
Why Duncanville Homes Are Different
Duncanville is a largely built-out inner-ring suburb. The residential core was developed almost entirely between 1965 and 1985, so the overwhelming majority of homes here contain original ductwork now 40 to 60 years old. That is a far higher concentration of aging systems than you find in newer outer suburbs like Midlothian or Mansfield. Combine that with a North Texas cooling season that runs HVAC equipment nearly nonstop from June through September, and these decades-old systems have accumulated multiple generations of dust, fiberglass insulation fragments, and allergen load that most homeowners have never had professionally addressed.
The terrain matters too. The blackland prairie clay soil beneath Duncanville’s slab foundations causes seasonal heave and settlement. On many 1970s ranch homes, that movement gradually separates duct boots from floor or ceiling registers. The system ends up pulling loose attic fiberglass insulation directly into the air stream. Our technicians see this pattern repeatedly in the older streets off Wheatland Road and in the neighborhoods east of Main Street. It is not a rare failure here; it is a predictable one.
Our Main Duncanville Services
Duncanville homeowners call us most often about two jobs: cleaning the ducts that move heated and cooled air, and cleaning the HVAC equipment itself. Both matter here because the housing stock is old enough that original ductwork and air handlers are still in service.
Air Duct Cleaning in Duncanville
Full-system air duct cleaning in Duncanville means opening every supply and return run on a home that was likely built before modern filtration existed. We find collapsed flex liner, degraded insulation wrap, and dust packed into the plenum. Each run is photographed before and after, and you receive that photo record as part of the job. The full breakdown of this service, including what it costs here, is on the dedicated Air Duct Cleaning in Duncanville page.

HVAC Cleaning in Duncanville
HVAC cleaning in Duncanville focuses on the equipment itself: the evaporator coil, blower wheel, drain pan, and the air handler cabinet. On systems that have run through 40-plus Texas summers, the coil is often loaded with a felt-like mat of dust and pet hair that cuts airflow and forces the compressor to work harder. We clean it with professional-grade equipment and show you the before and after photos. See the full scope on our HVAC Cleaning in Duncanville page.

Before
AfterDryer Vent Cleaning in Duncanville

Dryer vent cleaning in Duncanville is not a convenience job. On homes built from the mid-1960s through the mid-1980s, the dryer vent is often a long flex run snaking through an attic or a slab chase, and after four or five decades it is carrying a lint load that restricts airflow and holds moisture against the duct wall. That is a fire hazard, and it is also why dryers in Duncanville take two cycles to dry a load that used to take one. Our Dryer Vent Cleaning service starts with a camera inspection so you see the restriction before we quote a price.
Dryer Vent Inspection
Signs you need it
Clothes come out damp after a full cycle, the dryer feels hot to the touch on the outside, or you cannot remember the last time anyone looked inside the vent.
What it costs in Duncanville
A camera inspection of the dryer vent in Duncanville typically runs $75 to $150, and that amount is credited toward the cleaning if you proceed.
How we do it
We run a camera from the dryer connection to the exterior termination, record the footage, and show you exactly where the restriction is before any cleaning begins.
Lint Removal
Signs you need it
The dryer takes longer than 45 minutes per load, the exterior vent flap barely moves, or there is a visible mat of lint packed around the termination outside.
What it costs in Duncanville
Full lint removal from the dryer vent in Duncanville typically runs $129 to $199 for a standard single-story run.
How we do it
We use a Rotobrush system with a high-torque cable to break the lint free and negative-pressure extraction to pull it out, then we photograph the clean run end to end.
What Dryer Vent Cleaning Costs in Duncanville
| Item | Typical range in Duncanville |
|---|---|
| Camera inspection | $75 - $150 |
| Standard lint removal | $129 - $199 |
| Full service with bird guard | $189 - $289 |
Two things push the price up in Duncanville: runs longer than 15 feet, which are common in ranch homes where the laundry sits on an interior wall, and vents that terminate through the roof instead of an exterior wall. If you want an exact price, we put it in writing before any work starts.
How often should a dryer vent be cleaned in Duncanville?
Every 12 months is the safe interval for a 40-year-old vent in a home where laundry runs more than twice a week. Homes with long attic runs or multiple pets should lean toward every 6 months.
Why does my Duncanville dryer vent clog so fast?
Older flex runs have interior ribbing that catches lint, and in Duncanville’s humid spring weeks that lint holds moisture and compacts. A 1970s vent with multiple elbows will clog far faster than a short, straight modern run.
Duct Repair & Sealing in Duncanville

Duct repair and sealing in Duncanville is the direct answer to a housing stock problem: original flex duct from the 1970s and 1980s is now past its service life, and the blackland clay soil heave has pulled boots loose from registers. The result is air leaking into the attic while the system pulls attic dust and fiberglass into the house. Our Duct Repair & Sealing work fixes both the leaks and the contamination path, and every repair is photographed before and after.
Duct Sealing
Signs you need it
Rooms at the end of a run stay warm in summer, the system runs longer than it used to, or you see dust streaks on the ceiling near supply registers.
What it costs in Duncanville
Sealing accessible duct joints in a typical Duncanville ranch home runs $250 to $500, depending on the number of runs and how many joints are reachable.
How we do it
We locate every failed joint with a pressure test, then apply a brush-on mastic sealant rated for HVAC ductwork and verify the seal with a second reading.
Flex Duct Repair
Signs you need it
You can see collapsed or sagging flex runs in the attic, or the inner liner has separated and the duct is pulling attic air directly into the house.
What it costs in Duncanville
Replacing a failed flex run in Duncanville typically runs $180 to $350 per run, including materials and the mastic seal at both connections.
How we do it
We cut out the damaged section, install a new R-6 or R-8 flex run sized to the original, seal both ends with mastic, and photograph the finished work.
What Duct Repair & Sealing Costs in Duncanville
| Item | Typical range in Duncanville |
|---|---|
| Duct joint sealing (per system) | $250 - $500 |
| Flex run replacement (per run) | $180 - $350 |
| Boot reconnection at register | $75 - $150 |
In Duncanville, the biggest price driver is access. Attic-mounted systems on slab homes can mean tight crawl spaces and long tool runs, which adds labor time. Every quote is a written flat price per system agreed before work starts.
Can duct sealing actually lower my cooling bill in Duncanville?
Yes. Sealed ducts stop cooled air from dumping into the attic, which means the system reaches temperature faster and cycles off sooner. Homes with major joint failures often see the biggest drop after sealing.
How do I know my ducts were actually sealed?
Our photo record shows every joint before and after mastic is applied, and the pressure test before and after gives you a number that shows the difference. You do not take our word for it; you see it.
Air Quality & Sanitizing in Duncanville

Air quality and sanitizing in Duncanville targets what decades of allergen load leave behind inside ductwork: pollen from spring oak and mountain cedar, pet dander, and in the worst cases, mold at flex-duct joints where condensation forms during damp winters. Cleaning alone removes the debris, but sanitizing addresses the biological load that remains. Our Air Quality & Sanitizing service applies an EPA-registered antimicrobial and verifies the result with a photo record.
Mold Treatment
Signs you need it
You see dark staining at a supply register, smell a musty odor when the system first kicks on, or a visual inspection shows growth at flex-duct joints in the attic.
What it costs in Duncanville
Mold treatment for ductwork in a typical Duncanville home runs $400 to $900, depending on the affected area and whether the contaminated flex runs need replacement.
How we do it
We identify the affected area, remove contaminated flex where necessary, apply an EPA-registered antimicrobial to the remaining surfaces, and photograph the treatment process.
UV Light Installation
Signs you need it
Anyone in the home has persistent allergy symptoms indoors, or the coil area shows recurring microbial growth despite cleaning.
What it costs in Duncanville
UV light installation in Duncanville typically runs $500 to $900 installed, depending on the unit and whether it is mounted at the coil or in the return plenum.
How we do it
We mount a UV-C unit at the evaporator coil using a kit sized to your air handler, wire it to run when the blower operates, and verify the lamp output before we leave.
What Air Quality & Sanitizing Costs in Duncanville
| Item | Typical range in Duncanville |
|---|---|
| Mold treatment (ductwork) | $400 - $900 |
| UV light installation | $500 - $900 |
| Whole-system sanitizing | $250 - $450 |
Homes east of Main Street and off Wheatland Road, where slab heave has pulled boots loose for years, often need both repair work and sanitizing because attic dust has been pulled through the system for a long time. The written quote covers both, itemized, before we start.
Does sanitizing replace duct cleaning in Duncanville?
No. Sanitizing kills surface growth but does not remove the debris that supports it. A Duncanville system with 40 years of dust needs mechanical cleaning first, then sanitizing, or the growth returns.
Will a UV light help with Duncanville’s spring pollen?
Not directly. UV light addresses microbial growth on the coil, not pollen particles. Pollen requires better filtration and sealed ducts so it stops entering the system from the attic in the first place.
