Questions before you call
How soon can you come out for AC repair in Concord?
Call us and we'll give you the first available appointment. Concord is about 20 miles west via SR-4 and SR-242 from our Antioch shop. During heat waves the schedule fills fast, so calling early in the day helps.
How much does AC repair cost in Concord?
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.
