Furnace Repair
Mountain View, CA

Mountain View’s morning fog and winter temperatures dipping into the mid-30s mean furnace problems are urgent. The Cuesta Park and Waverly Park neighborhoods are full of 1950s–1960s homes where original gas furnaces are well past their 20-year expected lifespan. We repair every furnace type in Mountain View — from standing-pilot units in the oldest homes to high-efficiency condensing models in newer Whisman Station developments.

Furnace Repair in Mountain View: Fast Heat When You Need It

Mountain View’s furnace landscape splits along a clear generational line. Homes in Cuesta Park, Waverly Park, and the streets between El Camino and Central Expressway were built in the 1950s–1960s, and many still heat with original or once-replaced gas furnaces. These are typically 80% AFUE single-stage units with standing pilot lights or early electronic ignition. After 20–30+ years, the failure list is predictable: cracked heat exchangers (the most serious), worn-out blower bearings, failed gas valves, and ignitor burnout.

The Rex Manor and Gemello neighborhoods have slightly newer housing stock from the 1970s–1980s, with furnaces that may have been replaced once but are again approaching end of life. The most common call we get from these areas: furnace makes a clicking or humming sound but won’t ignite. Usually a $200–$350 ignitor or flame sensor fix.

Newer developments around Whisman Station, San Antonio Road, and the North Bayshore area run modern 95%+ AFUE condensing furnaces. More efficient, more complex. Electronic ignition, variable-speed ECM blower motors, and condensate drainage systems that need annual attention. When they fault, the diagnostic codes on the control board tell the story — if you know how to read them.

FAQ

Furnace Repair Mountain View — Common Questions

My Mountain View home’s furnace smells like burning when it first turns on in fall — is that normal?

A brief burning dust smell when the furnace fires up for the first time after summer is common and usually harmless — it’s dust that accumulated on the heat exchanger burning off. It should dissipate within 30 minutes. If the smell persists, smells like gas, or smells electrical/plastic, shut the furnace off and call us. Those could indicate a gas leak, overheating components, or wiring issues.

How often should I replace the furnace filter in a Cuesta Park home?

Every 60–90 days for standard 1-inch filters, which is what most Cuesta Park and Waverly Park furnaces use. If you have pets, run the fan continuously, or have allergy concerns, check monthly and replace when visibly dirty. A clogged filter is the #1 preventable cause of furnace breakdowns we see in Mountain View.

My furnace’s pilot light keeps going out — what should I check?

In older Mountain View homes with standing-pilot furnaces: first, check for drafts near the furnace (open windows, unsealed flue). If no draft, the thermocouple is likely failing — it’s a safety device that shuts off gas if it doesn’t detect flame, and they wear out over time. This is a common $150–$250 repair. If the pilot lights but the burners won’t fire, the gas valve may need replacement. Furnace troubleshooting.
