Homes in Los Altos
The Homes We Work On
Los Altos has one of the highest teardown-and-rebuild rates on the Peninsula, so it's common to find a brand-new custom home with a full multi-zone system next door to a 1950s ranch house still running its original single-stage furnace. Older homes in Old Los Altos and University Park usually need duct replacement or a full load recalculation before a new system goes in; new builds are typically designed for HVAC from the start.
Climate & Sizing
Los Altos sits between the fog-influenced hills and the warmer valley floor, so Country Club and the western neighborhoods run a bit cooler than University Park and the flats toward Sunnyvale. Summer afternoons still reach the low 90s valley-side, so we size for the home's specific exposure rather than the town average.
Rebates & Permits in Los Altos
Utility & Rebates
Silicon Valley Clean Energy (SVCE) supplies electricity in Los Altos; 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 Los Altos Building Division requires a mechanical permit and HERS testing for HVAC changeouts, and new-construction HVAC design typically goes through full plan review. We manage the permit and inspections either way.
