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 Burlingame
If you’re searching for Air Duct Cleaning in Burlingame, here’s what you need to know up front: a standard whole-system cleaning for a typical Peninsula home here runs between $425 and $650, covering the supply and return ducts, the evaporator coil, and the blower assembly. We work throughout Burlingame, from the Easton Addition to Burlingame Hills, and we quote one flat price per system before we touch a single vent register. Call (737) 727-2314 and a live person answers, day or night.
Burlingame’s housing stock splits hard between pre-1950 Peninsula bungalows and newer infill, and the older homes are the ones with original galvanized supply and return ducts buried in tight crawlspaces. That means HVAC Cleaning here often involves working on decades of settled dust and lint in low-clearance runs, not the wide-open flex-duct systems common in newer metro-area builds. Our team knows which blocks off El Camino Real hide those tight, awkward runs, and we come prepared for them.
Why Cardinal Air Duct Cleaning Is Burlingame’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, and our Burlingame customers hold us to a standard most duct cleaners never volunteer: The Relay Visibility Guarantee. That means you get a live trackable arrival time, before-and-after photos of your own ducts, and a digital invoice you can pay by link. No four-hour arrival windows. No “the tech will call you eventually.”
Our technicians are background-checked and arrive in uniform with a name you’ll know before they knock. For Burlingame specifically, that matters. Many homes in the Easton Addition and Ray Park neighborhoods have crawlspace access points behind lattice work or under decks, and our crews know how to work those tight spaces without tearing up landscaping. We also carry parts for the furnace and AC brands most common in older Burlingame homes, so a cleaning visit rarely turns into a week-long parts wait.
Omar Haddad, who leads our Bay Area operations, puts it this way: a cleaning job is only as good as the proof. That’s why every visit ends with photos showing exactly what came out of your system and what it looks like clean.
Evaporator Coil Cleaning in Burlingame
Evaporator Coil Cleaning in Burlingame is the single most overlooked part of HVAC maintenance, and coastal fog makes it worse here than inland. The evaporator coil sits inside your air handler and absorbs heat from the air. When it’s caked with a paste of dust and condensation, your system works harder, runs longer, and still leaves rooms feeling clammy. In Burlingame’s older bungalows, where the coil is often installed in a closet or crawlspace air handler, we see coils that haven’t been touched in ten or fifteen years. A professional coil cleaning in Burlingame typically runs $150 to $280 as part of a full system cleaning, and we do it with the system opened, not with a spray-and-pray aerosol from the register.
When a coil is heavily impacted, we remove and clean it outside the unit at no extra labor charge as part of the system price. The result is measurable: better temperature split across the coil, lower head pressure, and a system that doesn’t short-cycle. For Burlingame homeowners with allergies, this is often the difference between a bedroom that feels stuffy and one that actually holds 72 degrees.
What a Coil Clean Actually Involves
We isolate the air handler, remove the access panel, and apply a self-rinsing coil cleaner that breaks down the biofilm without eating the aluminum fins. Then we flush with low-pressure water and check the condensate line while we’re there. Clogged condensate lines are a frequent cause of water damage in Burlingame closets and garages, so we clear them as part of the job.
When Burlingame Homeowners Need This
If your AC runs constantly on warm afternoons but the air barely feels cooler than the room, or if you’re seeing moisture around the air handler, the coil needs attention. Homes within a mile of the Bay or along the El Camino corridor get more salt and fog residue in the air stream, which accelerates coil fouling. We recommend including coil cleaning every time, not as an add-on, because a clean duct run feeding a dirty coil is still a dirty system.
AC Duct Cleaning in Burlingame
AC Duct Cleaning in Burlingame means source removal, not just vacuuming what you can see at the register. We put your system under negative pressure with a Nikro HEPA-rated vacuum, then run agitation tools through the supply and return ducts to loosen everything stuck to the walls. That loose debris goes straight into the vacuum, not back into your living room. A full Burlingame home with eight to twelve registers typically runs $425 to $550 for the complete duct run, coil, and blower assembly.
For older homes here, the ductwork itself is part of the problem. Galvanized steel ducts from the 1940s and 1950s collect a fine, oily dust that flex-duct homes never see. Camera inspection before we start shows us the actual condition inside, including any disconnected joints or settled debris that source removal alone won’t fix. If we find a separated joint in a crawlspace off Broadway, we tell you and show you the photo. That’s part of the written report, not a mystery upsell after the fact.
Negative-Pressure Extraction Explained
Negative-pressure extraction means the vacuum is pulling harder than the agitation tools are pushing, so debris can’t escape into the room. We seal off the register we’re not working on and run the system one run at a time. For tight crawlspace jobs in Burlingame’s older bungalows, this matters: the last thing you want is decades of crawlspace dust blown into a finished bedroom.
What You See When We’re Done
Before-and-after photos are not optional with us. You’ll see the inside of your supply and return ducts on your phone before you pay. Every Burlingame job includes this because we’ve heard too many stories of companies that charged for cleaning and never moved the dust. The photos are time-stamped and yours to keep.
Trusted Brands We Service in Burlingame
We clean and service all major HVAC brands found in Burlingame homes, from Carrier and Trane to older Rheem and Lennox systems still running in pre-1970 houses. When a cleaning reveals a part that’s worn or about to fail, we stock common Honeywell and Aprilaire replacement filters and controls on our trucks, so we can often handle it same-visit rather than scheduling a return. For HEPA-level extraction, we run Nikro negative-air machines, and for containment in tight Burlingame garages and closets, we use Abatement Technologies containment units to keep the work area sealed. You’ll know exactly which equipment is coming to your house before we arrive.
Common HVAC Cleaning Problems We See in Burlingame Homes
- Settled crawlspace debris in older ductwork. Pre-1950 bungalows in the Easton Addition and Lyon-Hoag often have galvanized ducts sitting directly on the ground in low-clearance crawlspaces. Over decades, these fill with fine dust and occasionally disconnect at the joints. Camera inspection catches this; a quick register-only vacuum job never does.
- Fog-fed coil fouling. Homes west of El Camino get persistent marine layer moisture that mixes with household dust on the evaporator coil. The result is a gray paste that cuts airflow and makes the system run long cycles. This is a Burlingame-specific pattern we see far more than in San Mateo or inland Belmont.
- Per-vent pricing that hides the real work. A homeowner with 18 registers gets quoted a low per-vent rate and the actual load in the air handler and coil never gets touched. We quote one flat price per system so the scope is the whole system, not a register count that leaves the important parts dirty.
- No before-and-after proof. Homeowners here are savvy and want verification. If a company can’t show you photos of your own ducts after the job, you have no way to know the visible dust you saw at the register is actually gone from the supply and return runs deeper in the system.
Pricing for HVAC Cleaning in Burlingame, CA
A full HVAC system cleaning for a typical Burlingame home runs $425 to $650, depending on the size of the system and the number of returns. That’s one flat price per system, agreed in writing before we start. Evaporator coil cleaning and blower cleaning are included in that figure, not billed as separate line items. The only time price moves is if we find something broken that needs repair, and we show you the photo and get your approval before any repair work begins.
Smaller jobs, like a standalone blower cleaning or coil treatment without ductwork, run $150 to $280 depending on access and condition. Every quote includes camera inspection and before-and-after photos. You’ll never see a per-vent price from us because the important work isn’t counted by the register. Call (737) 727-2314 for a free estimate, and Omar or our team will walk through exactly what your Burlingame home needs.

FAQs About HVAC Cleaning in Burlingame
Most Burlingame homes need a full HVAC cleaning every 3 to 5 years. Older houses with crawlspace ductwork and original galvanized runs drift closer to the 3-year mark because the ducts collect more settled dust. If you have pets, live near the El Camino corridor, or run your system year-round, lean toward every 3 years. If your home is newer infill with flex duct and you run the system seasonally, 5 years is reasonable. The honest answer: you’ll know from the photos. If the return looks like the inside of a vacuum bag, you waited too long. Call (737) 727-2314 and we’ll tell you straight.
By the system, always. Per-vent pricing is how homeowners with 18 registers end up paying more for less work, because the air handler and evaporator coil never get touched. We quote one flat price for the complete supply and return duct run, the coil, and the blower assembly. That price is in writing before we start and does not change at the door.
Because the ductwork in homes built before 1950 often sits directly in low-clearance crawlspaces where joints settle, disconnect, and fill with debris over decades. A camera inspection shows us exactly what’s inside before we run agitation tools through it. Without that step, a tech treats every house like new construction and misses the real problem. The inspection is included in every Burlingame quote.
Yes, on every single job. You’ll get time-stamped photos of the inside of your supply and return ducts, the evaporator coil, and the blower wheel before and after cleaning. We ran a job off Burlingame Avenue in the Easton Addition on a 1940s bungalow where the homeowner had been waking up congested for months. Our tech put the system under negative pressure, ran agitation tools through the supply and return ducts, cleaned the evaporator coil and blower motor, then showed before-and-after photos of the caked dust inside the return and the lint pathway pulled off the blower wheel. That proof is yours to keep, and it’s part of The Relay Standard.
We don’t sell same-day promises because a proper HVAC cleaning is a scheduled job, not an emergency call. Most Burlingame jobs are scheduled within a few days of your call. If you have an urgent issue like a clogged condensate line or a blower that’s failed and needs immediate attention, call (737) 727-2314 and a live person will tell you exactly when we can be there. We answer the phone 24/7.
