Lafayette, Contra Costa County
Heating and air conditioning in Lafayette
Lafayette's custom and mid-century homes on hilly, wooded lots often come with tricky equipment locations and long duct runs.
Homes in Lafayette
Many Lafayette homes were built from the 1940s through the 1970s on large, sloped lots, with plenty of custom builds and later additions. HVAC equipment ends up in basements, crawlspaces, garages, and attics, and duct systems have often been extended piece by piece over decades of remodels. Some older homes never had AC.
Climate and what it means for your system
Lafayette is warmer than the bay side of the hills but often a bit milder than Walnut Creek. Summer afternoons are hot, nights cool off quickly, and winter mornings in low spots can be cold.
Most of Lafayette falls in California Title 24 climate zone 12. The exact zone is set by ZIP code, and we confirm it for your address when we design a system.
Utilities
PG&E delivers electricity and supplies natural gas. Electricity generation is provided by default through MCE, the community choice program, unless a household has opted out. Your bill will show which applies. This matters when comparing the operating cost of a heat pump against a gas furnace.
Permits
The City of Lafayette contracts with Contra Costa County for building inspection services, so HVAC permits for Lafayette addresses are processed through the county's Building Inspection Division. We handle the permit and inspection.
