Homes in Sunnyvale
The Homes We Work On
The Fairbrae and Fairwood Eichler tracts were built on radiant-heated slabs with no ductwork, the same as Palo Alto's Eichler neighborhoods — a ductless heat pump is the standard way to add cooling here. Downtown and the Heritage District mix older 1950s ranch homes with newer infill townhomes, and the older homes usually need a duct check before a straight equipment swap.
Climate & Sizing
Sunnyvale sits on the valley floor with minimal fog relief, so summer afternoons regularly reach the low-to-mid 90s. We size Eichler and slab-home systems for the whole radiant load, and standard homes with a full load calculation rather than a rule-of-thumb swap.
Rebates & Permits in Sunnyvale
Utility & Rebates
Silicon Valley Clean Energy (SVCE) supplies electricity in Sunnyvale; PG&E delivers the gas and maintains the grid. We check current SVCE/PG&E rebates at your free estimate — never a promised amount up front.
Permits & Inspections
The City of Sunnyvale Building Safety Division requires a mechanical permit and HERS testing for HVAC changeouts. We pull the permit and schedule inspections.
