Fast, Reliable HVAC Cleaning Across Burlingame
We’re Bellows Air Duct & Vent Co., and we’ve been driving up the Peninsula to clean HVAC systems in Burlingame since 2012. Most days, we’re on your street within an hour of your call. We know the difference between a 1920s Craftsman on El Camino Real and a sound-insulated ranch in the Easton Addition, and we know what each one needs from a cleaning crew that actually looks at the ductwork before they quote you a price.
Burlingame’s situation is unlike anywhere else we work. Sitting directly under SFO’s flight paths, your home’s HVAC intakes pull in jet-exhaust byproducts and ultrafine particles at a volume no inland Peninsula city experiences. Hundreds of local homes, especially in the flat neighborhoods closest to the airport, were upgraded under the FAA/SFO Residential Sound Insulation Program. Those retrofits tightened building envelopes and modified HVAC systems, which means your sealed interior now depends almost entirely on clean ducts for breathable air. That’s not a talking point. It’s why we camera-inspect every system before we start, and why we show you what we found before we quote.

Our HVAC Cleaning Services in Burlingame
Evaporator Coil Cleaning
Your evaporator coil sits in a dark, humid chamber, and in Burlingame’s persistently damp microclimate, that chamber never really dries out. We pull the coil, clean it with foaming agents that break down biological growth without damaging the aluminum fins, and treat it with antimicrobial protectant. A dirty coil in Burlingame doesn’t just reduce efficiency, it becomes a mold factory that pumps spores into every room. We see this most often in the older Spanish Colonial homes near the 94010 zip code, where original sheet-metal plenums hold moisture against the coil housing.
Blower Cleaning
The blower wheel moves every cubic foot of air your home breathes. When it’s coated with the fine particulate that SFO jet exhaust deposits in Burlingame systems, it works harder, runs hotter, and wears out faster. We remove the blower assembly, clean the wheel and housing with compressed air and contact-safe solvents, and balance the assembly before reinstalling. In homes near the airport, we often find a gray film on blowers that doesn’t match typical household dust, it’s a signature of ultrafine combustion particles that standard filters don’t catch.
Condenser Cleaning
Your outdoor condenser faces Burlingame’s salt-laden marine air year-round. That salt accelerates corrosion on aluminum fins and copper tubing, and it attracts debris that blocks airflow. We wash the coils with low-pressure foaming cleaner, straighten damaged fins, and clear the condensate drain. For coastal Burlingame homes, particularly those in the flat neighborhoods between Highway 101 and the Bay, we recommend more frequent condenser checks than our inland customers need.
Air Handler Cleaning
The air handler is the heart of your system, and in Burlingame’s mixed-age housing stock, it’s often the most neglected component. We clean the entire cabinet, including the drain pan, insulation lining, and all accessible duct connections. In the Easton Addition and Burlingame Park neighborhoods, where FAA sound-insulation retrofits left fresh ductwork mated to original 1920s trunk lines, we pay special attention to the junction points. Those connections are where hidden gaps form, where condensation pools, and where mold takes hold.
Heat Exchanger Cleaning
Gas-fired furnaces in Burlingame’s older homes need heat exchanger inspection and cleaning to maintain safe, efficient operation. We visually inspect for cracks and corrosion, then clean the exchanger surfaces to restore heat transfer. Given the age of much of Burlingame’s housing stock, we never skip this step on pre-1960 systems.
Coil Treatment
After cleaning, we apply EPA-registered antimicrobial treatments to coil and plenum surfaces. In Burlingame’s humid environment, this isn’t optional, it’s what keeps biological growth from returning before your next service. We use Abatement Technologies products specified for residential HVAC systems, applied at concentrations that are effective against mold and mildew without introducing irritants into your air stream.

Trusted Brands We Service in Burlingame
We stock parts and specify equipment from Nikro, Honeywell, and Abatement Technologies, the same brands serious HVAC contractors use when they’re building systems to last. For Burlingame customers, that means no waiting on special orders for most repairs, and no substitutions with hardware-store-grade alternatives. Our technicians carry Honeywell media filters and Aprilaire humidifier components on their trucks, so if we find a failed part during your cleaning, we can usually replace it same-day. We’ve learned that in Burlingame’s climate, the right component matters more than the fast fix.
Common HVAC Cleaning Problems We See in Burlingame Homes
- Biological growth in low-velocity return ducts. Burlingame’s Bay-front humidity creates ideal conditions for mold and mildew to colonize return-air sections and poorly sealed joints. Unlike drier Peninsula cities, duct contamination here skews heavily toward biological growth rather than just dust accumulation.
- Collapsed flex-duct at mixed-age junctions. The FAA sound-insulation program installed new ductwork alongside original systems, and the connection points between old trunk lines and new flex runs are prone to separation. We regularly find hidden debris traps where these materials meet.
- Corrosion of sheet-metal ducts and fasteners. Salt-laden marine air accelerates deterioration in the 1920s-1940s homes that define Burlingame’s residential fabric. Original galvanized steel doesn’t hold up forever against this environment.
- Particulate loading from SFO overflight. Jet exhaust deposits ultrafine particles that standard filters miss. These accumulate in blower housings and on coil surfaces, reducing efficiency and potentially affecting indoor air quality in tightly sealed homes.

FAQs - HVAC Cleaning in Burlingame
Yes. Homes retrofitted under the FAA/SFO Residential Sound Insulation Program have tighter building envelopes and modified HVAC systems, which means indoor air quality depends almost entirely on duct cleanliness. We inspect the junction points between original trunk lines and new retrofit ductwork with our camera system, because those connections are where gaps and mold colonization most commonly occur. Call (844) 685-6342 to schedule an inspection of your retrofitted system.
Most Burlingame homes under SFO flight paths benefit from HVAC cleaning every 2-3 years, rather than the 3-5 year interval typical for inland Peninsula cities. The additional ultrafine particulate loading from jet exhaust accelerates buildup in blower housings and on coil surfaces. Homes with residents who have respiratory sensitivities may need annual service. Call (844) 685-6342 and we’ll assess your specific exposure and system condition.
We specify professional-grade equipment from Nikro, Honeywell, and Abatement Technologies, the same brands installed by serious HVAC contractors. Our technicians carry these products on their trucks, which means most Burlingame jobs are completed in a single visit without waiting for parts. Call (844) 685-6342 to ask about specific components for your system.
Yes. Burlingame’s persistently humid coastal microclimate, combined with the Bay-front marine layer that pushes moisture into homes year-round, creates conditions where mold and mildew colonize ductwork more readily than in drier Peninsula cities to the south. Our camera inspections regularly show biological growth in low-velocity return sections and at unsealed joints, particularly in pre-1960 homes with original sheet-metal systems. Call (844) 685-6342 for a free inspection and upfront quote.
Yes, and we take particular care with the coil housings in Burlingame’s 1920s-1940s housing stock, where original sheet-metal plenums may have degraded seals that allow moisture to accumulate. We remove the coil for thorough cleaning, treat it with antimicrobial protectant, and inspect the surrounding plenum for corrosion or gaps. In the 94010 and 94011 zip codes, we’ve found that coil cleaning often reveals the first signs of systemic moisture problems that need addressing. Call (844) 685-6342 to schedule service.
