Why Crestview Heating & Air California Is Millbrae’s Preferred Heating & Furnace Company
We’ve built our reputation in Millbrae one job at a time. Our 4.8-star average across 250+ customer reviews reflects real performance on real homes here, not curated testimonials from somewhere else. Millbrae homeowners call us back because Marcus Feldman, our owner, still serves as Service Manager, which means ownership-level accountability shows up with every technician.
Our familiarity with Millbrae’s specific conditions saves time and money. We know the hillside ranch homes west of El Camino Real, the SFO noise-insulation retrofits that changed how these houses breathe, and the detached workshops on larger properties that need heavy-duty solutions. That local knowledge means faster diagnosis and fewer callbacks.
We respond to Millbrae calls with the urgency you’d expect when your heat goes out on a foggy January morning. Emergency HVAC service is available for those off-hours failures, and we stock parts for Trane, Lennox, Carrier, and Goodman systems to avoid supply delays.
Our Heating & Furnace Services in Millbrae
Furnace Repair
Millbrae’s older forced-air systems work hard through our cool, foggy winters, especially in the western hillside neighborhoods where temperatures drop lower than the bayfront flatlands. We repair gas valves, ignitors, blower motors, and control boards on all major brands. A typical furnace repair in Millbrae runs $150–$700 depending on the part and accessibility. We regularly diagnose short-cycling caused by oversized units in homes that received SFO noise-abatement window retrofits, the envelope got tighter, but the furnace stayed the same size.
Furnace Replacement
When your furnace is beyond repair or costing too much to keep running, we size the replacement properly for your home’s actual load, not its original 1950s–1970s construction specs. This is critical in Millbrae. Thousands of homes here were insulated and sealed through the FAA/SFO noise program, dramatically tightening building envelopes that were originally designed leaky. An oversized replacement will short-cycle, waste fuel, and fail prematurely. We perform proper Manual J load calculations that account for your address elevation, window retrofit status, and orientation. Furnace replacement in Millbrae typically runs $3,500–$7,500.
Furnace Tune-Up
Annual maintenance catches problems before they become emergency calls. In Millbrae, we pay special attention to combustion safety on older atmospherically vented furnaces, especially in hillside homes where SFO window retrofits have tightened the envelope so much that original bath and kitchen exhaust fans can backdraft. Our tune-up includes burner cleaning, heat exchanger inspection, gas pressure verification, and airflow measurement. A furnace tune-up in Millbrae costs $80–$200.
Heat Exchanger Inspection & Replacement
This is safety-critical work. A cracked heat exchanger can leak carbon monoxide into your living space. In Millbrae’s older housing stock, we’ve found heat exchanger failures accelerated by years of short-cycling, the constant on-off stress that oversized furnaces endure in tightened homes. We inspect with visual and combustion analysis tools, and we replace heat exchangers or entire furnaces when the damage is beyond safe repair. Never ignore a CO detector alarm or the smell of combustion gases.

Common Heating & Furnace Problems We See in Millbrae Homes
- Short-cycling after SFO noise-abatement retrofits. The FAA/SFO program replaced windows and added insulation in thousands of Millbrae homes, tightening envelopes beyond what original oversized furnaces were designed for. The furnace blasts heat, satisfies the thermostat too quickly, and shuts off, repeating every few minutes. This wastes gas, wears components, and creates temperature swings.
- Backdrafting in hillside homes with atmospherically vented furnaces. When powerful exhaust fans compete for air in a tightened home, they can pull combustion gases down the flue instead of letting them rise. We’ve found this on multiple properties above Millbrae Avenue. It’s a combustion-safety red flag that demands immediate attention.
- Failed ignitors and gas valves on original equipment. Many Millbrae homes still run their original furnace from the 1970s or 1980s. Hot surface ignitors crack after years of thermal cycling, and gas valves develop intermittent failures. These are straightforward repairs if diagnosed correctly.
- Detached workshop furnaces neglected and overstrained. Properties with acreage or large lots often have separate units in workshops or garages. These systems see irregular use, minimal maintenance, and sometimes heavy-duty door traffic that strains the whole environment. They fail precisely when you need them for a project.

FAQs — Heating & Furnace in Millbrae
Short-cycling is usually caused by an oversized furnace in a home that’s been tightened by SFO noise-abatement window retrofits. The furnace produces more heat than the now-sealed home can absorb, so it quickly hits the thermostat setpoint and shuts down. We see this constantly on the hillside streets above Millbrae Avenue. The fix is a proper load calculation and often a correctly sized replacement unit. Call (844) 560-6978 for a free assessment.
Yes. Any smell of combustion gases indicates a potential carbon monoxide hazard that requires immediate professional inspection. In Millbrae workshop units, we often find cracked heat exchangers or backdrafting caused by negative pressure in tightly sealed structures. Turn the system off and call us. We stock replacement parts for fast repair, and we can verify safe venting before you restart.
Yes. We’ve handled tight crawlspaces, steep driveways, and restricted attic hatches throughout Millbrae’s hillside neighborhoods. We measure access routes before ordering equipment, and we coordinate crane or specialized rigging when standard methods won’t work. Marcus Feldman personally reviews challenging access jobs to make sure we bring the right crew and equipment for one-trip completion.
Almost certainly smaller than the original unit. The SFO noise program’s window and insulation upgrades reduce your heating load significantly. We’ve replaced 100,000 BTU furnaces with 60,000 BTU units in retrofitted Millbrae ranches and seen better comfort, lower bills, and longer equipment life. We perform ACCA Manual J load calculations specific to your address, elevation, and retrofit status, never a rule-of-thumb guess.
Yes. We’re factory-trained on both Trane and Carrier systems, and we carry common parts for both brands on our trucks. Whether you have a newer variable-speed Carrier or a decades-old Trane XL90, we can repair, maintain, or replace it. Our 19 years of experience covers virtually every model year you’re likely to encounter in Millbrae’s housing stock.
