Furnace Repair in Santa Clara: Every Neighborhood, Every System

Santa Clara’s furnace issues follow predictable patterns by neighborhood and era. Lick Willow and blocks between Benton Street and El Camino Real feature 1950s–1970s homes. Many still have original forced-air gas furnaces — oversized 80,000–100,000 BTU units with standing pilot lights. These furnaces were built to last, but they’re increasingly prone to cracked heat exchangers, failed ignitors, and worn blower motors.

Around Santa Clara University, multi-unit buildings use wall furnaces, central gas furnaces, and some older electric resistance heating. Property managers call us when tenants report no heat, uneven temperatures, or gas odor. We handle all of it, including the safety inspections required after gas-related repairs.

Newer developments along Agnew Road have modern 95%+ AFUE condensing furnaces with variable-speed blowers. More efficient but more complex — electronic ignition, ECM motors, and condensate drainage that clogs in winter. When these fault, the control board error codes require trained interpretation.

FAQ

Furnace Repair Santa Clara — Common Questions

My furnace clicks but won’t light — is this dangerous?

If you smell gas, leave immediately and call PG&E at 1-800-743-5000. If no gas smell, the most likely cause is a failed hot surface ignitor or dirty flame sensor — both common same-day repairs. In older Lick Willow homes we also see failed thermocouples on standing-pilot furnaces. Furnace troubleshooting.

How do I know if my heat exchanger is cracked?

Signs: visible soot around the burner, yellow or flickering pilot (should be blue), CO detector alarms, or a metallic smell when the furnace runs. For Santa Clara homes built before 1980, we recommend inspection every 2–3 years once the furnace passes 15 years. We use camera inspection and combustion analysis.

Do you service wall heaters in apartments near Santa Clara University?

Yes. Wall furnaces and gravity heaters are common in older multi-unit buildings around the University and along The Alameda. We repair and replace Williams, Empire, and Cozy brands. Property managers: we offer multi-unit visits to reduce per-unit cost.
