Atherton is a quiet residential town on the Peninsula, about 13.2 miles west of our Fremont base across the Dumbarton Bridge. It is known for large lots and substantial homes, many with guest houses, pool houses, and several separate heating and cooling systems.

TrustFix HVAC Repair Service supports Atherton homeowners and estate managers with multi-zone service, heat pump installation, furnace repair, and indoor air quality. Large properties need a clear picture of every system on site, and we help you keep that picture current.


Managing Several Systems on One Property

A main house might have three or four air handlers, while guest quarters and outbuildings use their own furnaces or mini-splits. Equipment often dates from different remodels and brands. We document what is on the property, service each piece, and flag the systems most likely to need attention next.

Main Residence Zoning

Larger homes rely on zone dampers, multiple thermostats, and sometimes communicating controls. We diagnose these systems so every wing stays comfortable.

Guest Houses and Outbuildings

Pool houses, studios, and guest cottages often run on ductless systems. We keep them clean and working so they are ready when needed.
