Heating & Air Conditioning in West Menlo Park, CA

Why do West Menlo Park permits go to the county?

West Menlo Park is not part of the City of Menlo Park. The county’s boundary commission lists it as an unincorporated community within Menlo Park’s sphere of influence, and the county’s Third District page names it among its unincorporated areas. That means the county, not the city, issues building permits for homes here.

What do West Menlo Park homeowners ask us?

Do Menlo Park’s heat pump rules apply to me?

Menlo Park’s local building code amendments apply inside city limits. Unincorporated homes follow the county’s codes instead. The county’s newest energy reach code, effective August 29, 2025, is written for new buildings. We will tell you what applies before you choose equipment.

Who is my electricity provider?

WestLight Energy, formerly Peninsula Clean Energy, was formed by the County of San Mateo and its 20 cities, and it says nearly all county residents are customers. As of November 2026, WestLight’s rebates and offers page lists rebates for heat pump water heaters and heat pump systems, plus a 0% interest loan. You may qualify; just call us and we’ll check what applies to your home.

Have you done work close by?

Yes, in nearby Palo Alto, including a heat pump that replaced a furnace and AC, and a water heater replacement. We don’t have a posted project in West Menlo Park yet.
