Bayhill Heat & Air, Inc.

Bayhill Heat & Air, Inc. has kept San Mateo comfortable for over four decades, operating since approximately 1984 under California contractor license 917996. The company maintains a 4.0-star rating across 19 customer reviews, serving residential and commercial clients throughout San Mateo, Foster City, and the broader Bay Area. Their physical presence in San Mateo positions them to handle the specific climate challenges of the Peninsula, where foggy mornings can shift to warm afternoon temperatures year-round.

What distinguishes Bayhill from other Peninsula contractors is their in-house sheet metal fabrication capability, a specialized trade that allows custom ductwork and installations without subcontracting. They offer indoor air quality solutions including REME HALO systems, thermostat and zoning installations, and air duct sealing services. The company provides service agreements with extended warranty options and maintains financing programs for new installations and replacements.

Reviewers consistently highlight technician Ricardo by name for exceptional service. One customer described Ricardo arriving at 5:30 PM on his way home to fix a wiring issue in two minutes at no charge. Another homeowner reported Ricardo conducted a live video diagnosis of a heater buzzing noise, resolving the simple issue without requiring a house call. Multiple reviewers emphasize that Bayhill does not charge for diagnostic visits, a practice that sets them apart from competitors who quoted $200 just for coming out.
