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 West Covina, CA
Dryer vent cleaning in West Covina deals with a specific set of problems: Ranch-style homes built between the 1950s and 1970s, long vent runs through hot attic spaces, and air that carries diesel particulate from the I-10 and SR-60 corridors straight into the house. Our crews work these systems every week, and the photo record from each job tells the same story: lint that compacts faster here than in coastal LA, because inland heat bakes it solid inside the pipe. Call (806) 606-6902 for a written price before any work begins.
Why West Covina Homes Are Different
West Covina sits in a pinch point of the eastern San Gabriel Valley air basin. The South Coast AQMD consistently ranks this inland corridor among the worst in LA County for PM2.5, and the geography explains why: the San Gabriel Mountains trap fine particulate that drifts in from the I-10 and SR-60, both of which cut directly through or alongside the city. Diesel ultrafine particles from those freeways find their way into return-air ducts within months, not years. In neighborhoods near South Hills and the streets flanking Puente Hills, our technicians routinely pull dark, carbon-gray debris from return ducts, a sharp contrast to the lighter tan dust we see in homes a few miles north toward the foothills.
The housing stock compounds the problem. West Covina’s growth surge left a dominant inventory of Ranch-style single-family homes, most with original sheet-metal or early flex-duct systems. Those ducts run through attics that hit 140 to 160 degrees in summer, and that heat cycle after cycle degrades duct board insulation and joint seals. Gaps open, particulates pull in, and the system becomes a collection point for freeway soot and wildfire ash. Homes here also run their HVAC hard, 10 to 15 degrees hotter than coastal LA on any given summer day, so the total air volume moving through the ducts each year is significantly higher than in beach-adjacent cities.
Our Main West Covina Services
These two services are what West Covina homeowners call us about most often, and each has its own dedicated page with local pricing and detail.
Air Duct Cleaning in West Covina
Full-system negative-pressure extraction, with a camera run through every duct before and after. In West Covina, the before photos typically show a gray-black film on the return side where freeway particulate has accumulated, plus loose insulation fragments in the supply runs. We document all of it, then clean to bare metal or liner. Air Duct Cleaning in West Covina
HVAC Cleaning in West Covina
HVAC cleaning here means cleaning the full air pathway: the return plenum, the blower assembly, the evaporator coil, the supply plenum, and every register run. That coil is the exact spot where West Covina’s high dust load collects first, and a fouled coil cuts airflow before the air ever reaches the ducts. HVAC Cleaning in West Covina

BeforeAfterDryer Vent Cleaning in West Covina
Dryer vent cleaning in West Covina isn’t just about lint; the same freeway particulate that darkens return ducts here also enters the dryer vent system, where it mixes with lint and hardens faster than in coastal homes. Long vent runs through 140-degree attic spaces compound the problem, because heat bakes the lint-and-soot mix solid, narrowing the pipe and raising dryer exhaust temperatures until the thermal fuse trips, or worse. Before any work starts, we provide a written price under Haven Standard Clause 1, and every Dryer Vent Cleaning job concludes with a photo record of the vent’s interior. For full documentation of the job, see our Dryer Vent Cleaning page.
Lint Removal
Signs you need it
The dryer takes 55 minutes or longer to finish a normal load, or the exterior vent hood flap doesn’t fully open during the cycle.
What it costs in West Covina
Standard lint removal in West Covina typically falls between $89 and $159 as part of a full vent cleaning job.
How we do it
We run a rotating brush the full length of the vent, then a negative-pressure vacuum pulls every dislodged lint plug into a sealed canister while the camera documents the pipe’s interior from both ends.
Vent Rerouting
Signs you need it
The vent run exceeds 25 feet, or it makes multiple 90-degree turns, or it terminates through the roof instead of an exterior wall, which is common in West Covina Ranches.
What it costs in West Covina
Vent rerouting in West Covina typically runs between $390 and $690 depending on the new run’s length and attic access.
How we do it
We map the shortest code-compliant path to an exterior wall, replace the existing run with rigid metal duct where applicable, and seal each joint with foil tape before photographing the completed installation.
What Dryer Vent Cleaning Costs in West Covina
| Item | Typical range in West Covina |
|---|---|
| Dryer vent cleaning (standard, up to 15 ft) | $89-$159 |
| Extended run or multi-story vent | $150-$240 |
| Vent rerouting with new rigid duct | $390-$690 |
How often should I clean my dryer vent in West Covina?
Every 12 months if you run two or more loads weekly, and every 9 months if freeway proximity or pets add particulate load. Call (806) 606-6902 and we’ll give you a written price up front.
Why does my dryer vent clog so fast in West Covina?
Diesel particulate from I-10 and SR-60 mixes with lint and bakes hard inside the pipe in attic heat. That combination forms blockages faster than the nearly pure lint common in coastal cities.
Duct Repair & Sealing in West Covina
Duct repair and sealing in West Covina usually means dealing with the aftermath of decades of attic heat on 1950s and 1960s sheet-metal ductwork. Joints that were sealed with tape and mastic in the Eisenhower era have dried, cracked, and separated, and every gap pulls 140-degree attic air into the supply stream while leaking conditioned air into the attic. That’s money spent cooling a space no one lives in, and it’s also how freeway particulate keeps re-entering a system even after a thorough cleaning. Every job starts with a written scope, and each run is photographed before and after; see our Duct Repair & Sealing hub for the full breakdown.
Duct Sealing
Signs you need it
Rooms on the far end of the house stay warm in summer, or your cooling bill has crept up while the system runs more often.
What it costs in West Covina
Whole-system duct sealing in West Covina typically runs $690-$1,450 depending on the number of runs and attic access.
How we do it
We open each accessible joint, clean the mating surfaces, apply mastic sealant and embed mesh tape, then run a pressure test to verify the improvement before photographing the sealed joints.
Flex Duct Repair
Signs you need it
You see a crushed or kinked flex run in the attic, or a run has sagged between supports and is pinching airflow to a register.
What it costs in West Covina
Flex duct replacement in West Covina typically falls between $280 and $580 per run, materials and labor included.
How we do it
We cut the damaged section back to the nearest good joint, fit new insulated flex duct of the same diameter, seal both ends with mastic and zip ties, and document the new run with a final photo.
What Duct Repair & Sealing Costs in West Covina
| Item | Typical range in West Covina |
|---|---|
| Whole-system duct sealing with mastic | $690-$1,450 |
| Flex duct run replacement | $280-$580 per run |
| Duct insulation repair or wrapping | $220-$490 per section |
How do I know if my West Covina ducts need sealing?
Look for uneven room temperatures, rising cooling costs, or visible dust collecting near registers. A technician can confirm with a pressure test; call (806) 606-6902 for a written quote.
Can duct sealing help with West Covina’s freeway dust?
Yes. Sealing gaps prevents unfiltered attic air, which contains freeway particulate, from entering the airstream in the first place. Sealed ducts stay cleaner far longer after a professional cleaning.
Air Quality & Sanitizing in West Covina
Air quality and sanitizing in West Covina is a response to what the air actually carries here: PM2.5 from the eastern San Gabriel Valley air basin, diesel ultrafine particles from the I-10 and SR-60, and seasonal wildfire ash from fires like the 2020 Bobcat Fire that burned just north of the city. After we complete a full duct cleaning, sanitizing the interior surfaces and installing the right air purification hardware can meaningfully reduce what recirculates through the home. Every Air Quality & Sanitizing job concludes with the same photo documentation as our cleaning work; see the Air Quality & Sanitizing hub for full scope details.
Mold Treatment
Signs you need it
A musty smell persists from the registers, or visible dark staining appears inside a duct or on the register face, usually after a period of high indoor humidity.
What it costs in West Covina
Duct interior mold treatment in West Covina typically runs $450-$900 depending on the number of affected runs.
How we do it
We apply an EPA-registered antimicrobial fog to the full duct interior, agitate visible growth with a brush, then photograph the treated surfaces and provide a written report of what was found and treated.
UV Light Installation
Signs you need it
You notice recurring mold or mildew growth on or near the evaporator coil, which stays damp and dark in West Covina’s long cooling seasons.
What it costs in West Covina
UV light installation in West Covina typically falls between $390 and $680 for a single-lamp coil-mounted unit.
How we do it
We mount a UV-C lamp to the supply plenum or directly above the evaporator coil, run the wiring to a dedicated circuit, and verify lamp output with a radiometer before photographing the final installation.
What Air Quality & Sanitizing Costs in West Covina
| Item | Typical range in West Covina |
|---|---|
| Duct interior mold treatment | $450-$900 |
| UV-C light installation | $390-$680 |
| Whole-home air purifier installation | $520-$1,100 |
Will sanitizing my ducts remove diesel smell from the freeway?
Sanitizing removes biological contaminants, but particulate is removed mechanically. Pair sanitizing with a full duct cleaning and air purifier installation to address both; call (806) 606-6902 for a written price.
How long does duct sanitizing last in West Covina’s climate?
Expect 12 to 18 months of residual protection in a typical Ranch home before re-treatment makes sense. Higher particulate load from the freeways shortens the window compared to coastal homes.

FAQs About Air Duct Cleaning in West Covina
Plan on 3 to 5 hours for a standard single-family Ranch with one air handler. Older sheet-metal systems in tight attics may push that toward 6 hours with documentation included.
Most single-family homes in West Covina are not HOA-governed, but some newer developments and townhome communities do require notice for exterior vent modifications. We’ll confirm with you before any exterior work begins.
Yes. The I-10 and SR-60 corridors load West Covina ducts with diesel particulate that keeps recirculating long after it settles. A full cleaning with photo documentation removes what’s accumulated, and sealing prevents more from entering.
