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 San Bruno
HVAC cleaning in San Bruno, CA typically costs $250 – $550 for a full system, and most jobs take 2 – 4 hours. That price includes the supply and return ducts, the blower, and the AC coil when it’s accessible. If you’re off Sneath Lane or up near Crestmoor, call us at (737) 727-2314 and we’ll give you a written price before any work starts.
We know San Bruno’s rhythm. Fog rolling over the mountain in the morning, SFO arrivals overhead by noon, and a house that ran heat at 7 a.m. now cycling AC at 3 p.m. That daily swing moves dust and moisture through your air handler in a way inland Peninsula cities just don’t see. Our HVAC Cleaning team works in San Bruno every week, and we schedule around your day, not the other way around.
Why Cardinal Air Duct Cleaning Is San Bruno’s Preferred HVAC Cleaning Company
Homeowners across San Bruno, from the 50s-era ranches near Tanforan up to the newer builds near the 94066/94080 line, keep us busy for one reason: we tell them the truth about what their system needs. Omar Haddad set the standard from day one. Written price before work begins. Before-and-after photos. A 365-Day Done Right Promise on every job, not just some. When we say the coil needs cleaning, we show you a photo of the coil.
Reviews from San Bruno customers mention the same three things: the tech arrived in a live window they could track, the price they were quoted was the price they paid, and the before-and-after photos proved the work was done. That’s The Relay Standard, and every booking with us includes it. Background-checked, uniformed technicians. A live person answers the phone 24/7. No bait pricing, no per-vent upcharges mid-job.
We respond to San Bruno calls from the San Francisco Bay Area dispatch office, and crews serving San Bruno carry Rotobrush agitation tools, Nikro HEPA vacuums, and Abatement Technologies containment units. Professional gear, not a truck-mounted shop-vac.
AC Coil Cleaning in San Bruno
AC coil cleaning in San Bruno is one of the most skipped services we see, and it’s the one that costs homeowners real money. Your evaporator coil sits inside the air handler, and in San Bruno’s morning-heat/afternoon-AC cycle, it runs wet more often than dry. Dust sticks to a damp coil and becomes a mat. That mat chokes airflow, forces the compressor to work harder, and shortens system life. A coil cleaning for a typical San Bruno home runs $120 – $220 when done as part of a full HVAC cleaning.
What We Actually Do
We pull the access panel, inspect the coil with a camera, and show you what we’re seeing. Then we apply a professional coil cleaner and gently rinse or vacuum the fins, depending on how caked they are. If the coil is accessible from both sides, we do both. If it’s boxed in, we tell you exactly what we can reach and what we can’t. No fog-and-go theater.
Signs the Coil Needs It
Weak airflow at the registers, longer runtimes to hit the thermostat, or a slight musty smell when the AC first kicks on. If your energy bill in a 1960s tract home off Cherry Avenue has crept up and nobody can explain why, the coil mat is the usual answer. We’ll confirm with photos before we clean it.
AC Cleaning in San Bruno
AC cleaning in San Bruno means going beyond the coil. It’s the blower motor, the blower wheel, the air handler housing, and the return plenum. A standard AC cleaning in San Bruno runs $200 – $400, and we flag anything that looks worn while we’re in there. Belt fraying on an older unit, a blower wheel caked in dust, a drain pan starting to rust. You get a report with photos, not a vague “everything looked fine.”
Blower and Air Handler Work
On a job off San Mateo Drive near the Tanforan side of town, our tech pulled a heavily linted blower motor from a system serving a 1950s ranch. The wheel was so loaded that the motor was drawing high amps. We ran agitation tools through the supply and return ducts, held negative pressure the whole time so nothing migrated into the living room, and then cleaned the blower assembly. The homeowner saw before-and-after photos from their own registers and air handler, and they could see the coil mat the AC coil cleaning lifted off before we reinstalled anything. That’s source removal, and it’s the only kind of AC cleaning we do.
Condenser and Heat Exchanger Checks
On the outdoor unit side, condenser cleaning in San Bruno runs $90 – $150. Fog-laden air and dust from the flight path settle on the condenser fins, and a clogged condenser rejects heat poorly. We rinse the fins, check the fan, and let you know if the unit is still moving air the way it should. Heat exchanger cleaning happens mainly on gas furnaces and can run $150 – $250 depending on accessibility. If a heat exchanger is cracked, we don’t clean it; we flag it in writing and recommend a licensed HVAC tech evaluate it. Your safety matters more than a completed line item.
Trusted Brands We Service in San Bruno
We service and clean systems from Carrier, Trane, Lennox, Goodman, Rheem, and Daikin, and we stock common filters and parts for San Bruno jobs so most work gets done in one visit. If your system uses a Honeywell or Aprilaire filter cabinet, we’ll check the seal and replace the media if you want. We carry Guardsman filtration products for homeowners looking to reduce the dust that South San Francisco wind currents push through older window seals. Tell us your system brand when you call, and we’ll come with the right filter sizes on the truck.
Common HVAC Cleaning Problems We See in San Bruno Homes
- Linted blower motors on 1950s – 1960s ranch homes. The long, branched return runs in these older San Bruno houses collect more debris than newer open-plan builds. A matted blower wheel drags on the motor and shortens its life.
- Moisture-cycled dust on the evaporator coil. Morning fog and afternoon sun mean the coil runs wet and dry in the same day. That cycle bakes dust into a crust that a simple filter change won’t touch.
- Per-vent pricing surprises. Some companies quote $29 per vent and “find” 25 vents once they’re inside. We price per system, in writing, before we start.
- Register fogging without source removal. Fogging deodorizes; it doesn’t clean. If a company won’t show you the inside of your air handler before and after, they’re not doing the job you’re paying for.
Pricing for HVAC Cleaning in San Bruno, CA
Here’s the straight answer, because San Bruno homeowners deserve it. A full HVAC cleaning for a typical San Bruno home runs $250 – $550, and that’s one flat price per system agreed in writing before we touch a single duct. AC coil cleaning alone runs $120 – $220. AC cleaning, including the blower and air handler, runs $200 – $400. Condenser cleaning runs $90 – $150. Heat exchanger cleaning, where applicable, runs $150 – $250.

FAQs About HVAC Cleaning in San Bruno
Every 3 to 5 years for most San Bruno homes. If you run heat in the morning and AC by afternoon through the fog season, or you live under the SFO flight path, you may lean closer to every 3 years. Homes with pets, recent construction, or a smoker in the house also accumulate faster. Call (737) 727-2314 and we’ll give you an honest read over the phone; if your system doesn’t need it yet, we’ll tell you that, too.
Per system, always. You get one flat price for the entire HVAC cleaning job before we start, and it doesn’t change at the door. Older San Bruno ranches with long branched returns often trigger per-vent quotes elsewhere that balloon fast. We don’t do that. The price Omar Haddad signs off on is the price you pay.
We run Rotobrush agitation tools through your supply and return ducts, keep a Nikro HEPA vacuum pulling negative pressure the entire time so loosened debris goes into the vacuum rather than back into your living room, and set up Abatement Technologies containment where needed. We clean the blower, air handler, and AC coil if accessible, and we photograph everything. Before-and-after photos of your own ducts are part of every job.
When the coil is accessible, AC coil cleaning is included in the full HVAC cleaning price. We don’t hide it as an upsell. If the coil is in a location that requires significant disassembly, we’ll quote that separately and in writing before any part of that work begins. You’ll know exactly what’s included and what’s not.
We don’t promise same-day service, because a proper HVAC cleaning is a scheduled job that takes 2 – 4 hours. What we do promise is a live arrival window you can track by phone, not a four-hour range. Call (737) 727-2314 and we’ll schedule the soonest available slot, often within a few days for San Bruno calls.
