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.
Fast, Reliable HVAC Cleaning Across Cypress
HVAC cleaning in Cypress usually means one thing: a 50-to-70-year-old duct system that has never been opened, let alone documented. We clean the evaporator coil, blower, air handler, and condenser on Cypress ranches built between 1955 and 1975, and we photograph every duct run before and after so you can see what was actually removed. Tomas Reyes leads our crews, and every Cypress job starts with a written price before a single panel comes off. Call (806) 606-6902 to schedule, and we’ll walk the system with you on arrival.
Why CleanRun Air Duct Cleaning Is Cypress’s Preferred HVAC Cleaning Company
Cypress homeowners deal with a specific set of HVAC problems other Orange County cities don’t face at the same intensity. The marine layer off the Pacific sits over Cypress most nights, pushing humidity into original fiberglass duct board that was installed when Eisenhower was in office. We have cleaned enough Cypress systems to know what that moisture does inside a duct run: microbial staining, liner separation, and disintegrating fiberglass shedding into supply air. That’s what our camera sees before we touch anything.
Our customers in Cypress consistently tell us the same thing: they want documentation, not a sales pitch. That’s why every job includes a Documented Photo Record of every duct run, inside, before and after. You get the photos as part of the standard job record. You also get a written price under Haven Standard Clause 1 before work begins. No “call for a quote” games. The price is written down, in dollars, and handed to you before the first panel opens.
We’re background-checked, uniformed, and identified by name before arrival. The equipment we bring to Cypress includes Rotobrush, Nikro, and Honeywell tools you can look up independently. When we finish, you receive the HVAC Cleaning record, a written scope of what was done, and a written 365-Day Done Right Promise. If the work isn’t right, we make it right. In writing.
Our HVAC Cleaning Services in Cypress

Most Cypress homes we clean are 1,200 to 1,800 square feet with an HVAC system that has been running since the Nixon administration. Here’s what we address, and what we typically find in Cypress specifically.
Evaporator Coil Cleaning
The evaporator coil on a Cypress ranch sits directly in the airstream after 50+ years of marine-layer humidity. What we find is a coil caked with a gray paste of dust, biological growth, and degraded fiberglass from the duct board. We clean the coil in place with professional-grade cleaners, then photograph it before and after so you can see the fin surfaces restored. A dirty coil doesn’t just smell musty; it drives up runtime and fails to pull humidity out of air that is already too humid.

Air Handler Cleaning
The air handler is where most Cypress systems hide their worst conditions. We remove the blower housing, clean the fan wheel blade by blade, and vacuum the secondary drain pan where standing water feeds mold. On a recent 1,400 sq. ft. ranch north of Cerritos Avenue near the SR-91 corridor, we found visible microbial staining on the original fiberglass duct board and a crushed section of flex duct kinked behind the air handler. Our crew used negative pressure and agitation tools to remove the contamination, replaced the crushed run, and sealed the supply and return connections to stop the leak. That’s what a real air handler cleaning in Cypress looks like.

Condenser Cleaning
The outdoor condenser on Cypress homes gets hit with coastal salt air and constant fine particulate from traffic corridors. We clean the coil fins, straighten bent sections, and check refrigerant line insulation. A condenser packed with salt-laden grime can’t reject heat, which means your evaporator coil works harder and the whole system runs longer. On Cypress’s north side near the SR-91, condensers accumulate a dark film of brake dust and diesel particulate that requires a targeted degreaser, not just a rinse.

Coil Treatment
After cleaning, we apply an anti-microbial coil treatment on most Cypress systems. The marine layer means coils here re-contaminate faster than in Anaheim or Fullerton, a dozen miles east and measurably drier. On fiberglass-lined systems, we treat the accessible plenum surfaces too. This isn’t a spray-and-run step; it’s applied after the underlying buildup is removed, and it’s documented in the photo record.

AfterTrusted Brands We Service in Cypress
We service and clean HVAC systems from every major manufacturer installed in Cypress homes over the last six decades, including original equipment still running from the 1960s and 1970s. Our crews carry guardsman-style coil treatment applicators, Rotobrush negative-pressure extraction equipment, and Nikro HEPA-filtered vacuums. We stock common replacement components for ageing Cypress systems, including flex duct sections, collars, filter media, and coil cleaning agents. If your system is older than the technician who installed it, we have seen it before.
Common HVAC Cleaning Problems We See in Cypress Homes

- Deteriorating fiberglass duct board: The original duct board from the 1960s breaks down after decades of marine-layer moisture, releasing fiberglass particles into supply air. Homeowners often mistake this for ordinary dust until a camera inspection shows the liner standing out from the duct wall. The fix is removal and sealing, not just vacuuming.
- Disconnected flex duct runs in attics: Early-generation flex duct sags, separates at joints, and gets crushed by boxes, storage, or critters in Cypress attics. A disconnected run dumps conditioned air into the attic, which means the system runs constantly and still can’t hold temperature. We camera-inspect every accessible run and photograph the failure before we fix it.
- SR-91 particulate loading: Homes near the north end of Cypress, right along the freeway corridor, accumulate fine particulate in ducts and on coils at a visibly faster rate than homes a few blocks south. Without HEPA filtration during the clean, registers recontaminate within months. We run HEPA-filtered extraction on every Cypress job as standard.
- Microbial growth in the plenum: Marine-layer humidity infiltrates ducts at night, especially in older fiberglass-lined systems. By morning the interior surfaces of the plenum are damp enough to support biological growth. We find it most often in ranches where downspouts empty too close to the foundation or where bath fans vent into the attic instead of outside. We treat the surface, then we show you the photo and tell you what ventilation change prevents recurrence.

FAQs - HVAC Cleaning in Cypress

It includes camera inspection of every accessible duct run, negative-pressure extraction with HEPA filtration, evaporator coil cleaning, blower wheel removal and cleaning, air handler interior cleaning, plenum surface cleaning, coil treatment, and a written report with before-and-after photos of each run. For fiberglass duct board, the cleaning is only part of the job. If the liner is deteriorating or shedding, the real fix is sealing or replacement, and we quote that separately in writing before any repair starts. Call (806) 606-6902 for an exact number on your system.
The marine layer keeps relative humidity inside Cypress ducts significantly higher than in cities 10 to 15 miles east. That elevated overnight moisture accelerates biological growth inside fiberglass-lined duct runs, which means Cypress systems are more likely to need anti-microbial treatment as part of the clean. A household in Anaheim or Fullerton might go years between noticing musty supply air; Cypress systems show staining sooner. We treat for it, and we document it in the photo record.
The steady traffic flow along the SR-91 corridor pushes fine particulate matter into HVAC intakes at a rate significantly higher than quieter streets just a few blocks south. We see filter media turn dark in months, not years, and duct interiors accumulate a dense gray film that resists standard brushing. These systems need HEPA extraction during cleaning to avoid recontamination right after the job. On freeway-adjacent homes we recommend filter changes every 30-45 days, and we show you the before-and-after photo of the filter housing so the pattern is obvious. Call (806) 606-6902 for a written quote on a HEPA-filtered clean.
Yes, we clean it, but part of the job is inspecting every accessible run for sagging, separation, and crushing. Early-generation flex duct was never designed for 50 years of service, and in Cypress attics we routinely find runs that have disconnected at the collar or collapsed entirely. A clean on a system like this always includes a repair assessment with written pricing for any failed section. We don’t force a repair; we photograph it, write it down, and let you decide with the evidence in front of you.
Cleaning buys time, but it does not restore a duct board whose internal liner is separating or shedding fibers. The permanent fix is removal of the affected sections and replacement with sealed, non-porous duct material, plus sealing the supply and return connections at the plenum. We quote the replacement as a separate written line item, with photos of the deteriorated board included so you can see exactly why it needs to go. Every repair carries the 365-Day Done Right Promise in writing. Call (806) 606-6902 and we will inspect yours and give you the number on paper.
