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 summers are milder than East County, but hot spells still push Lafayette and Moraga into the 100s, and older homes without good insulation feel it fast.

Questions before you call
How soon can you come out for AC repair in Lamorinda?
Call us and we'll give you the first available appointment. Lamorinda is about 30 miles from our Antioch shop via SR-4 and SR-24. During heat waves the schedule fills fast, so calling early in the day helps.
How much does AC repair cost in Lamorinda?
It depends on what failed. A capacitor, contactor or clogged drain line is a small repair; a refrigerant leak, failed blower motor or compressor is a larger one. We diagnose first and give you the price before we start.
Should I repair or replace my air conditioner?
If your system is around 15 years or older, still uses R-22 refrigerant, or needs a major part like a compressor, replacing it is often the better investment. We'll show you both options so you can decide.
