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. Lamorinda has some of the oldest housing in our area, with many Lafayette homes built around 1960, and its hillside canyons run cooler in summer and colder in winter than the valley floor.

Questions before you call
Do you serve all of Lamorinda?
Yes. We serve all of Lamorinda. Call with your address and we'll confirm the first available appointment.
Do you work on both homes and businesses in Lamorinda?
Yes. Along with residential AC and heating, we repair, replace and maintain commercial systems such as rooftop package units and split systems for offices, shops, restaurants and apartment buildings.
What should I have ready when I call?
Your address, the type of system (central AC, gas furnace, heat pump or package unit), roughly how old it is, and what it's doing - noises, smells, error codes or no air at all. That helps us bring the right parts.
