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 San Bruno
HVAC cleaning in San Bruno typically costs between $425 and $1,150 depending on what’s actually inside your system, and a thorough job on a post-WWII tract home here takes a full day when done properly. That’s the honest range we quote on the Peninsula, and it’s the number we put in writing before a single panel comes off. If you live under the SFO departure corridors off Skyline Boulevard or near Sneath Lane, your ducts are working harder than a Burlingame system ever will, and we treat them accordingly. Call (806) 606-6902 and we’ll give you a written price, not a guess.
Why CleanRun Air Duct Cleaning Is San Bruno’s Preferred HVAC Cleaning Company
San Bruno homes present a specific challenge: aviation exhaust residue from SFO combined with persistent marine-layer humidity. Our HVAC Cleaning team has documented this combination in hundreds of local systems since 2013, and we’re familiar with how it shows up differently from Crestmoor to Portola Highlands. We don’t send a technician who’s learning San Bruno on your dime. We send a crew that already knows what a 1950s sheet-metal duct run off Huntington Avenue looks like on the inside before the camera goes in.
The work is led by Tomas Reyes, who has spent years training crews to inspect every duct run with a camera, agitate the debris mechanically, and extract under negative pressure rather than relying on a shop-vac and a wave. San Bruno homeowners want evidence, and we provide it: a documented photo record of the inside of every run, before and after, delivered with every job. That’s not a marketing promise. It’s a deliverable that’s been standard on every CleanRun visit since the company’s first job over a decade ago.
Our technicians are background-checked, uniformed, and identified by name before arrival. Every job is quoted with a written price before work starts, under Haven Standard Clause 1. And every visit ends with the 365-Day Done Right Promise in writing: if the work isn’t right, we make it right. San Bruno homeowners don’t need to wonder whether the job was actually done. They see it.
Our HVAC Cleaning Services in San Bruno

Evaporator Coil Cleaning
In San Bruno, evaporator coils collect more than household dust. The fine, dark particulate that comes from jet kerosene combustion settles on coil fins and reduces heat transfer, which means your system runs longer to hit the same temperature. We clean coils with professional-grade equipment from Rotobrush and Nikro, using negative-pressure extraction to pull loosened debris out rather than pushing it deeper into the system. Typical evaporator coil cleaning in San Bruno runs $180 to $340 as part of a full HVAC cleaning.

Blower Cleaning
Blower wheels in San Bruno homes near the flight path accumulate a compacted gray film that inland systems don’t get. This film unbalances the wheel, increases motor strain, and shortens blower motor life. We remove the blower assembly, clean the wheel blades individually, and photograph the result before reinstalling. Homes in the Westborough and Rollingwood areas often need this more urgently than homeowners expect, because the motor keeps working quietly until the buildup is severe.

Condenser Cleaning
Condenser coils on the exterior unit face San Bruno’s salty air and fog, which accelerates corrosion and attracts dirt to the fin surface. If the condenser can’t release heat effectively, the entire system loses efficiency and runs hotter, which shortens compressor life. Cleaning and fin combing on a typical San Bruno condenser runs $120 to $220. We inspect the full coil surface and don’t just rinse the outside face.

Air Handler Cleaning
The air handler is the heart of the system, and in San Bruno it’s often located in a damp crawlspace where marine-layer humidity sits for months. We clean the housing, the blower compartment, and the condensate pan, and we check for standing water and biological growth. Air handler cleaning runs $150 to $300 depending on access and condition. In crawlspaces with chronic moisture, we’ll document what we find and tell you plainly what’s fixable and what isn’t.

AfterTrusted Brands We Service in San Bruno
We work on all major HVAC equipment brands, and we stock common parts and filters for San Bruno customers so we aren’t running back across the Bay for a blower motor or a MERV 13 filter. Our equipment set includes Guardsman coils and filtration products, Nikro negative-pressure extraction machines, and Rotobrush agitation tools. These are professional-grade tools you can look up by name before you agree to a price. Honeywell filtration and media are also part of our standard offering, particularly where homeowners under the flight path want improved particulate capture.
Common HVAC Cleaning Problems We See in San Bruno Homes

- Jet-exhaust film on coils and blower wheels. Homes north and west of the city, especially near the Westborough corridor and Sneath Lane, see a fine gray residue that accumulates faster than anywhere else on the Peninsula. It compacts on blower wheels and insulates coil fins, cutting system efficiency measurably.
- Microbial growth inside flex ducts. San Bruno’s marine layer keeps crawlspace humidity above what’s typical for Bay Area homes. In flex ducts with pinhole tears or failing connections, that moisture supports mold and mildew colonies inside the duct wall. Fogging alone doesn’t fix this; the contaminated material needs source removal.
- Deteriorated flex-duct connections pulling crawlspace air. We routinely find original 1960s flex runs in Crestmoor homes that have never been replaced, with torn outer jackets and collapsed inner liners. The system ends up pulling unfiltered crawlspace air into the living space. Sealing those breaches is part of a proper HVAC cleaning, not an add-on.
- Mixed duct age on the same block. The 2010 PG&E pipeline explosion destroyed some Crestmoor homes completely, and those were rebuilt with modern duct systems. The house next door may have untouched 1950s sheet metal. A technician who quotes by house size alone gets the price wrong in Crestmoor more often than not.
Pricing for HVAC Cleaning in San Bruno, CA
A complete HVAC cleaning on a standard San Bruno tract home, including evaporator coil, blower, and air handler, runs $425 to $750. Larger homes or systems with an additional zone run $650 to $1,150. Condenser cleaning on its own is $120 to $220, and blower-only cleaning runs $150 to $250. Homes with significant jet-exhaust buildup and heavy coil film often land at the higher end, because the mechanical agitation takes longer and the extraction requires more passes. We don’t quote per vent and we don’t have a bait coupon. We write a single flat price for your system before work begins, every time. Call (806) 606-6902 for a written quote specific to your home.

FAQs - HVAC Cleaning in San Bruno

Yes, and we have the photo files to prove it. Homes in San Bruno’s departure corridors accumulate a fine, dark residue from jet kerosene combustion that we simply do not see at the same rate in Burlingame or San Mateo. The particulate infiltrates the home through air intakes and settles inside duct runs, on coils, and on blower wheels. Homeowners north of Sneath Lane and west of El Camino often replace filters at nearly double the rate of inland Peninsula homes. If you want to know whether your system has this buildup, our camera inspection shows it immediately, and you keep the photos. Call (806) 606-6902 and we’ll walk you through what we find.
Because Crestmoor is a patchwork. Some houses were rebuilt after the 2010 pipeline explosion with modern ductwork that cleans quickly. Others on the exact same block have original 1950s sheet-metal runs with torn flex connections and decades of accumulated debris. A one-size-fits-all price assumes both houses are the same; they aren’t. We quote based on what our camera sees in your specific system, not on square footage or number of vents. If you have a written estimate from another company, bring it to us. We’ll put our number next to theirs in writing, free, under our Free Second Opinion policy.
Generally, no. Fogging introduces a chemical mist that contacts the interior surfaces of the duct but does not remove the dead microbial material or the moisture that sustains it. In San Bruno’s marine-layer humidity, if the underlying moisture problem isn’t fixed, the growth returns. What actually works is source removal: physically cleaning the duct interior with mechanical agitation and negative-pressure extraction, then sealing breaches and addressing crawlspace dampness. We do offer air-quality sanitizing as a separate service using professional-grade products from Guardsman and Abatement Technologies, but we will tell you honestly when it’s redundant. If a company leads with fogging instead of cleaning, be skeptical. Call (806) 606-6902 and we’ll tell you what your ducts actually need and what they don’t.
Every 12 to 24 months for homes directly under the departure corridors. The aviation particulate film builds faster here than anywhere else on the Peninsula, and a coil with even a light film loses measurable heat-transfer efficiency. Homes in the Portola and Rollingwood neighborhoods frequently show visible coil fouling within a year of cleaning. Homes further south and east of Skyline may stretch to two years or more. We’ll tell you what your system shows and when to schedule again. If you’re unsure whether it’s time, the camera inspection gives you the answer in five minutes. Call (806) 606-6902 for a written quote.
Yes, because the smell isn’t coming from the air outside. It’s coming from the buildup inside your air handler and ductwork: the compacted jet-exhaust film on the blower wheel and the microbial growth inside damp flex ducts. When we remove that material mechanically and seal the breaches that pull crawlspace air into the living space, the odor source is gone. In a 1950s Crestmoor tract home off Cherry Avenue, our crew found original sheet-metal supply and return ducts with a quarter-inch of compacted lint and a distinct gray aviation-exhaust film. The camera showed deteriorated flex connections pulling crawlspace air, so we sealed the breaches, cleaned the evaporator coil with NADCA-compliant negative pressure, and upgraded the filter housing to a MERV 13. The homeowner reported noticeably less fuel odor and cleaner filters within six weeks. That’s what source removal does. A fogger doesn’t touch it.
