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 West Covina
HVAC cleaning in West Covina is not the same job it is in Santa Monica or Long Beach. The air here carries more weight in it: freeway diesel from the I-10 and SR-60 corridors, high-desert dust pushed in by Santa Ana winds, and fine particulate that settles into the San Gabriel Valley air basin and stays there. For a homeowner in a 1960s ranch near South Hills or a newer build east of Azusa Avenue, that means evaporator coils load up faster, blower wheels grind against grit, and return-air ducts hold carbon-gray debris that coastal contractors never see. We know this because we have pulled it out of ducts across West Covina for years, and we photograph every run before and after so you can see what was actually inside. If your system is moving visible dust or the registers are blowing air that smells stale, call (806) 606-6902 and we will put a written price in front of you before a single panel comes off.
Why CleanRun Air Duct Cleaning Is West Covina’s Preferred HVAC Cleaning Company
Homeowners here tend to research before they call. They want to know what a company actually does, what it charges, and what proof they will have when the truck pulls away. That is exactly how CleanRun has operated since 2013, under the Haven Standard. Every job starts with a written price. Every job ends with a Documented Photo Record of the inside of every duct run we touched. And every job is backed by the 365-Day Done Right Promise: if it is not right, we make it right, in writing.
Tomas Reyes, who leads our crews, has spent enough time in West Covina attics to know what the heat does to ductwork. Original sheet-metal ducts from the 1950s through the 1970s are common here, and the attic temperatures in July and August routinely sit 30 to 40 degrees above what you would find in a coastal home. That heat dries out joint seals and duct board, which is why so many local systems pull insulation fibers and attic dust into the air stream. Our techs see this constantly. The fix starts with a camera inspection, not a guess.
We also carry the equipment homeowners can verify independently: Rotobrush and Nikro agitation tools, negative-pressure extraction rigs from Abatement Technologies, and coil treatments from Honeywell and Guardsman. If you want to look up the tools before you approve the work, you can. We would rather you do that than take our word for it. HVAC Cleaning done without documentation is just noise. We hand you the record.
Our HVAC Cleaning Services in West Covina
Evaporator Coil Cleaning
The evaporator coil sits on top of your furnace or inside the air handler and is the single most common place West Covina systems lose efficiency. When the coil is coated with the fine gray dust so common in homes near the I-10, it cannot pull heat out of the air, so the system runs longer to hit the same temperature. A typical evaporator coil cleaning in West Covina runs $180 to $340, depending on access and how heavily the coil is loaded. We clean the coil in place or remove it when needed, then treat it with a coil cleaner matched to the metal type.
Blower Cleaning
The blower wheel is what pushes conditioned air through your ducts. In West Covina, blower wheels pick up a mix of desert dust, freeway particulate, and fibers from aging duct insulation. When the wheel blades get coated, airflow drops and the motor has to work harder. Blower cleaning runs $150 to $280 as part of a full HVAC cleaning on most local systems. Our techs pull the blower assembly, clean the wheel blades with compressed air and agitation, and photograph the wheel before and after so you can see the difference.
Condenser Cleaning
Your condenser is the outdoor unit, and it takes the brunt of Santa Ana wind events. In West Covina neighborhoods near the foothills and along the 10, condenser coils clog with a mix of Mojave dust, wildfire ash, and cottonwood debris from local parkways. A clogged condenser makes the whole system work harder, which shortens compressor life. Condenser cleaning in West Covina runs $120 to $220, including flushing the coil fins with a professional-grade cleaner and straightening bent fins where needed.
Air Handler Cleaning
The air handler is the box that houses the blower, the evaporator coil, and sometimes the heat exchanger. In older West Covina ranch homes, the air handler is often in the garage or a hall closet, which means it has been pulling in whatever the garage or closet has been collecting for decades. Air handler cleaning runs $220 to $400 on most local systems, and we clean the interior cabinet surfaces, the blower, the coil, and the drain pan as part of the job. Every surface we touch gets photographed before and after.

BeforeAfterTrusted Brands We Service in West Covina
We work on systems from the brands West Covina homes were actually built with, including Honeywell air handlers, Aprilaire filtration, and the full range of furnaces and split systems found in 1960s and 1970s ranch construction. Our techs stock the coil cleaners, blower pullers, and access panels needed for common local equipment, so we are not making runs to a supply house in the middle of your job. If you have a Honeywell air handler that has not been opened in years, we can tell you what is inside it before we start cleaning. If you have a Guardsman coil treatment on the books, we will tell you whether it is still doing anything.
Common HVAC Cleaning Problems We See in West Covina Homes
- Carbon-gray debris in return-air ducts near the freeways. Homes within a half-mile of I-10 or SR-60 pull in diesel ultrafine particles constantly. That material is dark, sticky, and heavier than ordinary household dust, and it builds up in return-air ducts fast enough that a system cleaned a year ago can already show visible carbon residue.
- Joint gaps in original sheet-metal ducts. West Covina’s 1950s-to-1970s tract homes often still have the original sheet-metal ductwork. Attic temperatures that hit 140 to 160 degrees in summer dry out the joints and seals, and the gaps pull in insulation and desert dust that then coat the blower wheel and evaporator coil.
- Santa Ana wind loading in outdoor intakes. When the winds blow out of the Mojave, they carry desert dust and, in recent years, wildfire ash from the San Gabriel Mountains, including material from the 2020 Bobcat Fire burn area. That dust packs into condenser coils and forces the system to work harder between cleanings.
- PM2.5 recycling through clogged coils. The eastern San Gabriel Valley basin traps fine particulate, which is why the South Coast AQMD consistently ranks this corridor among the worst in LA County for PM2.5. When the coil is loaded, the system recirculates that particulate through the house instead of trapping it.
Pricing for HVAC Cleaning in West Covina, CA
Here are the numbers, in writing, the way we give them before any work starts. A full HVAC cleaning that includes blower, evaporator coil, air handler, and condenser on a typical West Covina single-family home runs $380 to $680. Evaporator coil cleaning alone is $180 to $340. Blower cleaning is $150 to $280. Condenser cleaning is $120 to $220. Duct cleaning for a full system with 10 to 14 runs is $450 to $850. The price you get is the price you pay, per Haven Standard Clause 1: a written price before work begins, every time. What moves the number is access, system size, and how heavily loaded the components are. We do not charge per vent. We do not run a low teaser price and then add on after the truck arrives. You will know the number before we start.

FAQs - HVAC Cleaning in West Covina
Every 2 to 3 years for most West Covina homes, versus every 4 to 5 years in coastal cities like Long Beach or Santa Monica. The difference is the air quality and the particulate load. The I-10 and SR-60 corridors dump diesel ultrafine particles into surrounding homes year-round, and the San Gabriel Valley basin traps PM2.5 against the mountains. Call (806) 606-6902 and we can tell you what your own ducts are showing before you decide on an interval.
Yes, and we have the photos to prove it. Ducts in homes within a half-mile of either freeway consistently show dark, carbon-gray debris that we do not see in homes a few miles north. That material is heavier and stickier than ordinary dust, which means it builds up faster. Our tech servicing a 1970s ranch near South Hills pulled visibly dark, carbon-gray debris from the return-air ducts, a tell-tale sign of freeway diesel particulate accumulation from the I-10 corridor. We used negative pressure and agitation tools to source-remove the buildup, then cleaned the blower motor and evaporator coil on a Honeywell air handler that had been recycling PM2.5 for years. The homeowner noticed reduced dust settling within a week, and our camera inspection confirmed the registers were clear.
Because the Santa Ana winds push Mojave Desert dust and wildfire ash into your outdoor air intakes, and that material bypasses a standard filter or overwhelms it quickly. The dust loads the condenser coil first, then works its way into the return-air side as the system cycles. After a major wind event, the inside of your ductwork can look visibly worse in 48 hours. A post-wind cleaning of the condenser and return plenum, plus a coil inspection, is the practical response. Call (806) 606-6902 for an exact quote; estimates are free.
Yes, although the particulate profile is different. Foothill homes near Washington Rim or the neighborhoods east of the 57 pull in more wildfire ash and Mojave dust than diesel soot, but the loading is still heavy. The geography does the work: the San Gabriels block inland air, and the basin holds it. The interval is still every 2 to 4 years depending on elevation and wind exposure. We schedule cleanings in West Covina foothill neighborhoods every week and can tell you what your specific exposure looks like from the first camera pass.
Start with cleaning and a camera inspection. If the ducts are still structurally sound, cleaning the interior and resealing the joint gaps is often a better value than replacement. Original sheet-metal ducts are actually cleanable and resealable in most West Covina ranch homes, and the gaps at joints that open up from attic heat are often repairable with proper mastic and tape. If the camera shows rust-through or collapsed runs, replacement is the answer, and we will show you the footage and a written price before anything happens. Call (806) 606-6902 for a written assessment and a photo record of what we find.
