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 Fresno
HVAC cleaning in Fresno means confronting what the San Joaquin Valley puts into a duct system: agricultural dust from almond and citrus operations, PM2.5 from wildfire smoke, and the residue of ozone that settles out of inversion layers. A full HVAC cleaning here typically runs $480-$1,150 depending on system size and the condition of the components we find. Our crews coordinate dispatch from our Fresno, Central Valley office, so scheduling is straightforward and we know the housing stock. If you’re noticing musty air, reduced airflow, or dust settling back onto surfaces within days of cleaning, call (806) 606-6902. We’ll give you a written price before any work starts, and you’ll have a photo record of every duct run when we leave.
Why CleanRun Air Duct Cleaning Is Fresno’s Preferred HVAC Cleaning Company
Fresno homeowners tend to research before they commit. They want to see what’s actually inside the ductwork, not hear a sales pitch. That’s the standard we’ve held since 2013: every job starts with a written price, every run gets photographed before and after, and the 365-Day Done Right Promise means the work stays accountable long after the crew leaves. We don’t ask anyone to take our word for it. The camera sees what the camera sees, and you get the record.
Tomas Reyes leads our Fresno-area crews. He’s the one who reviews the photo records from every job before the file closes. That’s not a corporate formality. It’s the reason we can stand behind the written guarantee: someone with real authority checked the work. Our technicians are background-checked, uniformed, and identified by name before they arrive at your door, per Haven Standard Clause 3: Verified Crews.
Fresno’s older neighborhoods, especially central and southeast areas with 1960s-1990s tract homes, present challenges that a generic duct cleaning operation won’t recognize. We do. Original fiberglass duct board, early flex-duct systems, rodent intrusion through attic penetrations. We’ve seen it all, and we’ve documented it. The difference is we can show you what we found before we talk about what comes next.
Our HVAC Cleaning Services in Fresno
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and is where refrigerant absorbs heat from your home’s air. In Fresno, with summers pushing past 100°F for weeks at a stretch, the coil runs constantly. Dust and agricultural particulate from the valley air bond to the wet coil surface, creating a paste that insulates it and forces the system to run longer to hit the same temperature. We remove the coil, clean it with professional-grade coil cleaner, and photograph the before and after. This typically runs $180-$320 as part of a full HVAC cleaning in Fresno.
Blower Cleaning
The blower cage is the fan that moves air through your system. When the cage accumulates dust and char ash from Sierra wildfire events, it moves less air and strains the motor. In northwest Fresno homes with long duct runs from the 1990s-2000s buildout, a clogged blower means uneven cooling between rooms and higher energy bills. We pull the blower, clean the cage and housing, and check the motor amp draw before reinstalling. Expect $150-$280 for blower cleaning as part of a full service.
Condenser Cleaning
The condenser is the outdoor unit. In Fresno’s dry heat, it collects everything the wind carries: cottonwood fluff, harvest dust, grass clippings. A dirty condenser can’t reject heat efficiently, so the whole system works harder. We clean the coils from the inside out, straighten bent fins, and clear the surrounding area. Condenser cleaning in Fresno typically runs $120-$220. It’s straightforward work, but it’s work that has to be done differently here than in coastal cities where humidity keeps dust settled. Here, it’s airborne and it finds the coil.
Air Handler Cleaning
Air handler cleaning is the core of what we do in Fresno. The air handler is the indoor unit housing the blower, the evaporator coil, and often the heat exchanger. In older central and southeast Fresno homes with original duct board, the inside of the air handler is where fiberglass shedding, rodent debris, and years of accumulated PM2.5 all come together. We clean the entire cabinet under negative pressure with HEPA filtration, seal what needs sealing, and photograph everything. This runs $250-$450 depending on accessibility and condition.
Heat Exchanger Cleaning
If your furnace’s heat exchanger is caked with soot and fine dust, it can’t transfer heat efficiently and may overheat. In Fresno, where winter tule fog keeps particulate concentrations elevated during the heating season, this is more common than people expect. We inspect the heat exchanger for cracks while cleaning, because a cracked heat exchanger is a carbon monoxide risk. Heat exchanger cleaning runs $120-$250. If we find a crack, we’ll show you the photo and tell you exactly what it means before any repair is suggested.

We work on all major residential HVAC brands, and we clean systems rather than pushing replacements. Our HVAC Cleaning team uses professional-grade equipment from Rotobrush and Nikro for source removal, and Abatement Technologies HEPA filtration when contaminants require containment. We name the brands because you should be able to look them up and verify what’s being used. In Fresno’s market, that matters more than a slogan. If your system has specific components, we’ll tell you before we start how we plan to access and clean them.
Common HVAC Cleaning Problems We See in Fresno Homes
- Disconnected flex duct in attic chases. In 1970s and 1980s tract homes across central and southeast Fresno, the original flex duct often separates at the connection to the register boot. The blower pushes conditioned air into the attic instead of the bedroom, and your system runs longer for less comfort. Cleaning alone doesn’t fix it. The run has to be reconnected or replaced, and then cleaned.
- Crumbling fiberglass duct board. Decades of 100°F attic heat cause original duct board to degrade internally. The inside surface sheds fiberglass particles into the airstream. You can’t see it from the register, but the camera shows it. This requires source removal and often a recommendation to replace the compromised sections with properly sealed metal or new flex.
- Wildfire smoke residue in supply plenums. After major Sierra fires, like the 2020 Creek Fire that burned in the foothills directly east of Fresno, fine char ash and smoke-oil residue embeds in supply plenums and return boots. It coats the blower cage and evaporator coil. This is a Fresno-specific pattern that repeats most fire seasons, and it means filters need a higher MERV rating afterward or recontamination happens quickly.
- Rodent intrusion through attic penetrations. 1960s-1980s neighborhoods with aging gable vents see regular rodent access into return ducts. Nests and droppings inside the ductwork are a health concern, not just a smell problem. We remove the contamination under negative pressure, seal the entry point, and document the entire process.

FAQs - HVAC Cleaning in Fresno
You need it, and the almond dust is part of the reason. Fresno sits at the bottom of the San Joaquin Valley’s pollution bowl, where thermal inversions trap agricultural dust from almond, citrus, and grape operations year-round. Combined with recurring Sierra wildfire smoke, PM2.5 levels here rank among the worst in the U.S. That particulate enters your return ducts and accumulates measurably faster than in coastal cities. The dust on your furniture may be tree pollen. What’s inside your supply plenum is a darker, finer mix that includes char ash and ozone residue. A camera inspection will tell you which one you’re dealing with. Call (806) 606-6902 and we’ll show you.
Because the duct board itself is failing. In central and southeast Fresno, tract homes from the 1960s-1990s often have original fiberglass duct board that’s been baking in 100°F+ attic heat for decades. The interior surface degrades and sheds fiberglass into the airstream. A vacuum-out removes loose debris but doesn’t address the shedding surface. The real fix is removing the compromised runs, resealing the plenum with mastic to NADCA standards, and cleaning the supply side under negative pressure. We’ll show you photos of the duct board condition before recommending anything.
It contaminates them faster than a single cleaning can manage. When major fires burn in the Sierra foothills east of Fresno, northeast and northwest neighborhoods receive direct smoke drift. Fine char ash and smoke-oil residue embed in supply plenums, return boots, blower cages, and evaporator coils. We’ve pulled registers and found the blower caked with ash from a single summer’s fires. After cleaning, a higher MERV filter is necessary or recontamination happens within weeks. We’ll recommend the right filter rating for your system and your location within HVAC Cleaning in Fresno.
Yes. We remove nests and droppings under negative pressure with HEPA filtration, then seal the entry points so it doesn’t happen again. This is common in 1960s-1980s Fresno neighborhoods with aging gable vents. The cleaning addresses the contamination. The sealing addresses the recurrence. Both are included in our written scope of work, and both are photographed before and after. You’ll know exactly what was found and what was done about it.
Cleaning just the registers addresses what you can see. A full HVAC cleaning addresses what’s moving through your air: the blower, evaporator coil, air handler cabinet, supply plenum, return boots, and all accessible duct runs. In Fresno’s housing stock, what’s in the registers is usually a fraction of what’s in the system. We clean under negative pressure with source removal, not just surface wiping. The difference is visible in the photo record you receive at the end of the job.
Disconnected runs. During a recent cleaning in northwest Fresno, we pulled a supply register and found the original 1970s flex duct had fully disconnected inside the attic chase, so the blower had been pushing conditioned air into the insulation for years. The old duct board was shedding fiberglass into the airstream, and the blower cage was caked with fine char ash from that summer’s Sierra fires. We removed the compromised runs, resealed the plenum with mastic to meet NADCA standards, and cleaned the supply side under negative pressure with HEPA filtration before reconnecting a properly sized replacement. That’s what a full HVAC cleaning in Fresno is supposed to look for. The homeowner had been paying to cool an attic.
If you’re in Fresno and you want to know what’s actually inside your ductwork, call (806) 606-6902. We’ll schedule a visit, give you a written price before any panel comes off, and hand you a photo record of every run when the work is done. That’s the standard. It’s been the standard since 2013.
