San Mateo County

San Mateo County covers the Peninsula from the San Francisco line down to the Santa Cruz Mountains, with bayside cities on one side and coastal towns on the other. TrustFix HVAC Repair Service is based in Fremont, across the bay, and the communities on this page sit roughly 20 to 28 miles from our base, reached over the San Mateo or Dumbarton bridges.

Homes here range from older bungalows and row houses in the northern cities to hillside homes, rural properties in the redwoods, and coastal houses that see fog and salt air for much of the year. Heating is the main job for most systems, while cooling and heat pump upgrades are growing requests.

Homes and Requests Across the County

In the northern cities, many homes are older and compact, with furnaces in garages or hall closets and little room for ducts. Coastal homes in Pacifica, Montara, Moss Beach, and Half Moon Bay deal with damp air that can wear on outdoor equipment, and heating runs much of the year. Rural homes near La Honda and Loma Mar may rely on propane or electric heat and benefit from heat pumps or mini-splits.

Coastal Homes

Salt air and fog call for coil cleaning, corrosion checks, and equipment placed with some shelter from wind.

Older City Homes

Compact houses often do well with ductless heat pumps that add efficient heat and occasional cooling.
