Serving Lamorinda
We serve Lafayette and Moraga from our Antioch shop, about 30 miles away via SR-4 and SR-24, including Happy Valley and Burton Valley. Lafayette and Moraga review exterior equipment through planning first, then Contra Costa County handles building inspection, so hillside installs take a little more coordination. Many statewide heat pump rebates are closed for 2026, so when we quote we check what's still open for your address, such as MCE's home energy programs for Lamorinda customers and BayREN's income-qualified EASE Home program.

Questions before you call
Do I need a permit to replace my AC in Lamorinda?
Yes. Replacing an AC, furnace or heat pump in California requires a mechanical permit - in Lamorinda that comes from the City of Lafayette or Town of Moraga planning review, then Contra Costa County building inspection. Most replacements also need Title 24 duct leakage testing verified by a third-party HERS rater. We pull the permit and coordinate the inspection.
How much does a new AC cost in Lamorinda?
It depends on the size of the home, the type of system, the efficiency level and the condition of your ductwork. We give you a written quote after looking at the house, with more than one option.
Are there rebates for a new system in Lamorinda?
Some, but fewer than before. TECH Clean California and California's HEEHRA heat pump rebates are fully reserved, and the federal 25C tax credit ended for systems installed after 2025. What's left for Lamorinda homes is mainly MCE's home energy programs for Lamorinda customers and BayREN's income-qualified EASE Home program. Programs change often, so we check what's open for your address when we quote.
