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.

We’re CleanRun Air Duct Cleaning, and our technicians know the 1950s-through-1970s ranchers of Monta Loma, Rex Manor, and Blossom Valley better than anyone working between Shoreline and El Camino. If you want a real number before any work starts, call (806) 606-6902.
Why CleanRun Air Duct Cleaning Is Mountain View’s Preferred HVAC Cleaning Company
Mountain View homeowners don’t respond well to vague promises. The same engineer who reads a datasheet before buying a car seat reads ours before calling. So we lead with what we can document: a written price before the first panel comes off, a camera inspection of every duct run, and a before-and-after photo record delivered as part of every job. That’s been our standard since 2013, across more than 52,000 homes.
Our crews live and work here. We know that a Rex Manor rancher built in 1962 has different duct problems than a 1990s townhome near Castro Street. We know which blocks trend toward original sheet metal and which ones had ductwork retrofitted badly in the 1980s. That local knowledge changes what we find, and it changes what we quote. Our team serves all of Mountain View, from North Bayshore down through Old Mountain View, with scheduling coordinated from our San Francisco Bay Area office.
Our HVAC Cleaning Services in Mountain View
Evaporator Coil Cleaning
Evaporator coil cleaning in Mountain View typically runs $175-$360 as part of a full HVAC cleaning, depending on access and whether the coil has been cleaned in the past decade. The coil sits inside the air handler and is the cold surface that conditions air before it enters your ducts. In older Mountain View systems, we find a dense mat of dust and construction debris bonded to the coil fins by years of condensation. The fix requires pulling the coil, applying a professional-grade coil cleaner, and confirming airflow restoration with a before-and-after camera shot. Skipping coil cleaning while doing duct work is the single most common half-job we get asked to correct.
Blower Cleaning
Blower cleaning in Mountain View ranges from $125-$275, and it’s where we find the most avoidable failures. The blower wheel sits in the airstream, so everything your return ducts pull in collides with it. In rental-heavy neighborhoods like North Whisman and Monta Loma, tenant turnover means years of hair, dust, and cooking residue accumulating on the blower wheel, which forces the motor to work against an ever-heavier load. We clean the wheel and the motor housing with HEPA-filtered agitation tools, then photograph the result.
Condenser Cleaning
Condenser cleaning in Mountain View runs $110-$250 for the outdoor unit. The condenser sits outside, usually on the side of the house, and pulls air through a coil to reject heat. In tree-heavy neighborhoods like Blossom Valley and the streets off Cuesta Drive, we see condensers packed with pine needles, pollen, and construction dust from the ongoing teardown-and-rebuild cycle across the city. A clogged condenser makes your entire system work harder and shortens compressor life. We wash, comb, and verify airflow on every unit we touch.
Air Handler Cleaning
Air handler cleaning in Mountain View costs $160-$330 depending on whether the unit is in a closet, a crawlspace, or an unconditioned attic. The air handler is the cabinet that houses the blower, coil, and filters. In 1960s ranchers where the handler was shoehorned into a hallway closet decades after the house was built, we routinely find insulation pulled into the cabinet, rusted access panels, and condensate lines choked with sludge. We clean the full interior with a Guardsman or Rotobrush agitation system, then document it so you can see what was in there.

You can verify any of these independently before we ever set foot in your house.
Common HVAC Cleaning Problems We See in Mountain View Homes
- Retrofitted duct runs that trap debris: In Monta Loma and Rex Manor, many original wall furnaces were replaced with forced-air systems in the 1970s and 80s, and the new duct runs were routed through whatever ceiling cavities existed. The irregular geometry and mismatched transitions create dead zones where debris accumulates and standard cleaning rigs can’t reach.
- Smoke residue from wildfire seasons: Mountain View sits directly in the smoke corridor when fires burn west of the Santa Cruz Mountains. The 2020 CZU Lightning Complex pushed smoke through gaps in every vintage of ductwork, and we still find carbon staining inside supply runs in homes that never had a full mechanical clean afterward.
- Salt-air corrosion near North Bayshore: Persistent humidity and saline air off the bay accelerate corrosion on 1960s sheet-metal ducts in the low-lying districts northeast of 101. We see flaking galvanized interiors that harbor mold even when the visible registers look clean.
- Deferred maintenance in rental properties: Mountain View carries one of the highest renter-to-owner ratios in the Bay Area. Landlords managing from out of state often defer HVAC cleaning for five, eight, ten years at a stretch. The result is blower motors burned out from accumulated tenant debris and coils encased in years of residue.

FAQs - HVAC Cleaning in Mountain View
Landlords defer HVAC cleaning because they never see the inside of the ducts and because Mountain View’s rental market lets them re-lease a unit without touching the mechanical system. The ducts are invisible, the tenant turnover is constant, and no one is accountable for the slow buildup. What we find in these units is a consistent five-to-ten-year accumulation: blower wheels coated in residue, coils matted with pet hair and tenant debris, and return runs packed with dust from repeated move-in and move-out cycles. If you’re a tenant and your landlord won’t address it, ask for our written inspection report - it gives you documentation to present, and it gives us a record to work from. Call (806) 606-6902 and we’ll document what’s actually in there.
The telltale sign is uneven airflow: one bedroom always runs hot or cold, or registers in certain rooms blow noticeably weaker than others. The cause in Monta Loma is often a 1970s or 80s retrofit where the new forced-air runs were routed through ceiling cavities never designed for them. In one Monta Loma rancher, our crew found a collapsed supply run above the hallway ceiling - the original sheet-metal transition had detached, pulling attic insulation into the airstream. We used a camera inspection to map the disconnected run, removed the debris, then sealed and reconnected it to NADCA standards before source removal on the remaining ducts. If your airflow is uneven and your registers are decades old, the fix usually starts with a camera inspection, not a cleaning. Call (806) 606-6902.
Duct cleaning removes some smoke odor, but the full answer depends on what actually absorbed it. Smoke particles from the 2020 CZU Lightning Complex settled inside supply and return ducts throughout Mountain View, and in homes that ran the system continuously during the worst air quality days, the odor embedded in the blower assembly, the coil, and the duct walls themselves. A standard vacuum clean won’t fully remove it; what works is source removal with HEPA filtration and agitation tools on the duct surfaces, plus coil and blower cleaning to eliminate the odor at every point of contact. We include this full mechanical clean in our HVAC cleaning service. Call (806) 606-6902 and we’ll walk you through what’s still in your system.
Yes, and in Rex Manor specifically, salt-air exposure from the bay accelerates corrosion on original 1960s sheet-metal duct runs. The musty smell is mold growing inside the ducts, and it’s common in the low-lying neighborhoods northeast of 101 where humidity sits against uninsulated metal for years. The odor usually gets worse in summer when condensation forms, then fades in winter when the system runs dry heat. The fix is not a deodorizer sprayed into the register; it’s a HEPA filtration cleaning with agitation tools to remove the mold from the duct surfaces, plus inspection of the duct walls for corrosion that may require sealing or replacement. Call (806) 606-6902 and we’ll identify the source before recommending any work.
Los Altos homes are mostly purpose-built with duct runs planned during original construction, which means regular geometry, accessible runs, and consistent materials. Mountain View’s older ranches, especially in Monta Loma and Rex Manor, often have forced-air ductwork that was retrofitted into existing ceiling cavities in the 1970s and 80s. The runs are irregular, the transitions are mismatched, and debris accumulates in places a standard cleaning rig can’t see. That’s why we don’t sell a one-size-fits-all cleaning for Mountain View - the work requires camera inspection before we ever start, and often the real fix is sealing disconnected runs and correcting debris traps rather than just running a brush through. You see the documented evidence of what was found and what we did. Call (806) 606-6902 for a written price.
If you’ve read this far, you probably have a specific problem in mind. Call (806) 606-6902 and we’ll give you a written price for the work, a camera inspection of what’s inside your ducts, and a photo record when we’re done. That’s how CleanRun has worked since 2013, and it’s how we work in Mountain View every day.
