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 Cerritos
HVAC cleaning in Cerritos typically costs $425-$680 for a full system on a single-zone ranch home, with most jobs completed in 4 to 6 hours. The work focuses on the evaporator coil, blower assembly, air handler cabinet, and supply/return duct runs, using negative-pressure extraction so debris never re-enters living space. If you’re on a street near the 605 or 91 corridors, expect heavier soot accumulation than homes a mile west. Call (806) 606-6902 for a written price before anything gets opened up.
We know Cerritos not from a map but from the inside of its ductwork. The housing stock here is unusually uniform: ranch-style tracts built almost entirely between 1966 and 1985, on land that was dairy pasture a generation earlier. That matters because the duct systems in those homes are now 40 to 60 years old, and they’re degrading on a similar timeline. When we photograph the inside of a return plenum on a Cerritos home, we’re usually looking at original fiberglass duct board, early-generation flex duct with cracked inner liners, or both. This is a market where HVAC cleaning is as much about documenting what’s failing as it is about removing dust.
Why CleanRun Air Duct Cleaning Is Cerritos’s Preferred HVAC Cleaning Company
Homeowners in Cerritos tend to research before they call, and that’s exactly the type of customer our documentation model was built for. Since 2013, we’ve served over 52,000 homes with a process that hasn’t changed: a written price before work starts, a camera inspection at every register, and a photographic record of every duct run before and after. Cerritos customers receive the same folder on every job, showing the coil, the blower, and the plenum, as they looked when we arrived and when we left. No exceptions. That’s Haven Standard Clause 1: Written Price Before Any Work Starts.
Tomas Reyes leads our crews, and he holds every technician to the H.A.V.E.N. Standard: background-checked, uniformed, and identified by name before they step onto your property. Cerritos residents regularly tell us the photo record is the reason they didn’t go with a $79 coupon outfit. When you can see a 3-inch debris build-up at the first elbow in your return run, photographed on a tablet, before we touch it, the price stops being a guess. It becomes a scope of work.
Our response window to Cerritos is same-week for routine cleanings, with scheduling coordinated from our Los Angeles office and crews dispatched locally. We’re not a franchise, and we don’t run bait-and-switch pricing. We’re independently owned and operated, and every job ends with a 365-Day Done Right Promise in writing: if it’s not right, we make it right.
Our HVAC Cleaning Services in Cerritos
Evaporator Coil Cleaning
The evaporator coil sits above or beside the furnace and is where refrigerant absorbs heat from air passing over it. In Cerritos, where homes sit inland from the marine layer but close enough to catch dry Santa Ana dust events, coils accumulate a fine, baked-on film of dust and pollen that reduces heat transfer. A dirty coil forces the compressor to work harder, raising cooling costs. We remove the access panel, photograph the coil before cleaning, apply a non-corrosive coil cleaner, and rinse with low-pressure water. In homes near the 605, we often find a sooty residue that requires a second pass. Typical coil cleaning in Cerritos runs $150-$280 as part of a full HVAC cleaning package.
Blower Cleaning
The blower is the fan that pushes conditioned air through your ducts. In Cerritos’s 40-60-year-old systems, the blower wheel is frequently caked with a gray paste of dust and evaporated moisture, throwing the wheel out of balance. We pull the blower assembly, document the wheel’s condition, and clean each fin by hand rather than blasting it with compressed air, which can drive debris deeper into the motor bearings. Homes with pets or high freeway proximity tend to have heavier accumulation. Blower cleaning in Cerritos is priced at $120-$220, and we’ll tell you if a blower wheel replacement is advisable before we do anything.
Condenser Cleaning
The condenser is the outdoor unit, and in Cerritos it takes direct hits from the same dry westerly winds that carry soot and dust across the 605 corridor. We clean the coil fins with a condenser-safe degreaser and low-volume rinse, then inspect the fan and compressor wiring. A condenser coil that’s clogged with cottonwood fluff, which is common in the residential streets around Cerritos Regional County Park and Heritage Park, can raise head pressure and shorten compressor life. Condenser cleaning runs $110-$200.
Air Handler Cleaning
The air handler cabinet houses the blower, the coil, and often the filter rack. In older Cerritos homes, the interior of this cabinet is frequently lined with insulation that has begun to degrade, shedding fibers into the airstream. We clean the interior surfaces, replace the filter, and document any insulation breakdown we find. When a home shows significant fiber shedding, we recommend replacing the insulation or the entire handler, and we’ll put that recommendation in writing with photos. Air handler cleaning in Cerritos is $130-$250, depending on access and condition.
We also perform HVAC Cleaning on heat exchangers inside furnaces, which matters for any Cerritos home running a gas furnace in winter. A cracked heat exchanger is a safety hazard, not just an efficiency problem, and we’ll flag any concerns during the camera inspection. Our techs use Rotobrush and Nikro agitation tools alongside Abatement Technologies HEPA extraction units, so the dust pulled from your system is captured at 99.97% efficiency, not blown into the garage or attic.

BeforeAfterTrusted Brands We Service in Cerritos
We don’t just clean around brand names; we know the equipment. Cerritos homes run the full spectrum from original builder-grade units from the late 1960s to recent high-efficiency replacements, and our techs work on all of them. We carry common replacement filters, belt sizes, and coil treatment products for major residential systems, and we’re familiar with the compact mechanical closets typical of Cerritos’s ranch floor plans, where air handlers are often squeezed into a hallway closet or garage corner. If your system is newer, we recommend Coil Treatment after cleaning as a standard part of the job; it protects the coil surface and slows re-soiling. For customers in Cerritos who’ve had previous cleaning work done by other companies, we offer a Free Second Opinion on any written estimate: bring us their quote and we’ll put our own number next to it, in writing.
Common HVAC Cleaning Problems We See in Cerritos Homes
- Friable fiberglass duct board. Homes built between 1966 and 1985 often used fiberglass duct board for supply and return plenums. After four to six decades, the resin binder breaks down and the board crumbles on contact. Brushing it without negative pressure can dislodge fibers into the air handler, which is why our extraction units run continuously during cleaning.
- Cracked early flex duct. The first generation of flexible duct used a thin plastic inner liner that dries out and splits. When that inner liner cracks, air escapes into unconditioned attics and crawl spaces, pulling dust back in through the cracks. We photograph these cracks during our camera inspection and seal or replace runs as part of the job.
- Freeway soot accumulation near the 605 and 91. Our techs consistently pull heavier carbon and soot deposits from return plenums in homes along the western service roads of the 605 freeway than they do from same-vintage homes a mile west. Prevailing westerly winds push freeway exhaust across those blocks during afternoon hours when HVAC systems run hardest. The deposit pattern is visually distinct on camera: a dark, oily film rather than household dust.
- Undersized builder-grade returns. Return air openings in Cerritos’s ranch homes were sized for the original low-efficiency equipment, not for the higher-blower-power units many homeowners installed in the 1990s and 2000s. An undersized return forces the blower to work against high static pressure, which pulls unconditioned air in through register gaps and re-contaminates cleaned ducts. We identify this during cleaning and can upsize returns where access allows.
Pricing for HVAC Cleaning in Cerritos, CA
A full HVAC cleaning on a typical Cerritos ranch home, covering the evaporator coil, blower, air handler, and all accessible duct runs, runs $425-$680. Larger two-story homes or those with complex duct layouts can reach the high end of that range. Coil treatment adds $80-$120 per system and is worth doing if your home sits within a half-mile of the 605 or 91 corridors. Sealing work, which older Cerritos homes frequently need, is priced per linear foot after we document the leaks on camera, and we give you that number before any sealing begins.
The price we write is the price you pay. No per-vent add-ons, no upgrade pitch after the access panel comes off. Haven Standard Clause 1 means the written price is the total for the scope we agree on, before work starts. If we open a plenum and find a condition that changes the scope, we stop, show you the photo, and write a new price. You approve it or you don’t.
For an exact written price on your Cerritos system, call (806) 606-6902. We’ll walk through your home’s layout, duct type, and any known issues, and give you a number you can hold us to.

FAQs - HVAC Cleaning in Cerritos
Because the duct materials themselves are failing, not just dirty. Homes built during Cerritos’s conversion from Dairy Valley farmland to suburban tracts used fiberglass duct board for plenums and early flex duct for runs. Forty to sixty years later, that board is friable and the flex liners are cracked. Cleaning these systems requires continuous negative-pressure extraction to prevent fiber release, plus a camera inspection to document which runs need sealing or replacement rather than just cleaning.
Yes. We see measurably heavier carbon, soot, and oily particulate deposits inside return plenums and air handlers in homes along the western service roads of the 605 than in the same-vintage homes just a mile west. The pattern is consistent enough that we can identify it on camera before we know the address: a dark, sticky film that doesn’t resemble household dust. Prevailing westerly winds push freeway exhaust across those blocks in the afternoon when systems run hardest. These homes also need coil cleaning and filter replacement more often.
We stop and show you the photo. If a run is crushed or disconnected, cleaning it would be pointless because it’s not moving air anyway. We price the repair or replacement in writing, you approve it, and we do the work. On a street near the 605’s western service road, we found a 1978 ranch with original fiberglass duct board that crumbled on contact. The camera revealed a crushed return run and an undersized return plenum. After HEPA filtration and agitation tools cleared the debris, we sealed the runs and upsized the return, fixing the airflow, not just the dust.
It’s both legal and, in most cases, the single most effective thing you can do after cleaning. Aging homes in Cerritos regularly show 15-30% duct leakage. Sealing with mastic or specialized tape at accessible joints and seams is a standard practice, and we document every sealed section with photos as part of the job record. What we don’t do is apply a coating to the inside of your ducts without confirming the material is in good condition; in older Cerritos homes with friable duct board, sealing a degrading surface can create more problems than it solves.
Cerritos cycles between dry Santa Ana wind events and humid marine pushes. During the dry stretches, desert dust and allergens work into return registers. During the humid periods, moisture penetrates cracked flex liners and saturates dust inside fiberglass duct board, creating conditions where mold can grow. We see this most often in attics with poor ventilation and in supply runs that pass through unconditioned spaces. If our camera inspection finds evidence of mold, we recommend a specific sanitizing protocol and document the before and after.
Call (806) 606-6902 and we’ll schedule a time that works for you. You’ll get a written price upfront, a documented photo record of every duct run when the crew leaves, and a 365-Day Done Right Promise in writing.
