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. Mini-splits suit Lamorinda homes without ductwork, hot upstairs rooms, garage conversions and ADUs. 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
How much does a mini-split cost in Lamorinda?
It depends on the number of rooms (zones), the equipment, line-set length and whether your electrical panel needs work. We quote it after a site visit.
Can a mini-split fix one hot room?
Yes. A single-zone mini-split is one of the simplest ways to cool a hot upstairs bedroom, office or sunroom without touching the main system.
Are there rebates for mini-splits 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.
