Air Conditioner Repair in Walnut Creek and the Bay Area
AC not cooling, tripping the breaker, or icing up? We diagnose with gauges and meters, explain what we found in plain language, and fix the component that actually failed.
If a system is low on refrigerant, it indicates a leak that should be properly evaluated — anyone selling you a yearly top-off without finding the leak is selling you the same repair forever.
AC problems we fix: AC not cooling or barely cooling; Refrigerant leaks — found and fixed, not topped off; Capacitor, contactor, and relay failures; Condenser fan and compressor issues; Frozen coils and airflow problems; Breaker trips and electrical faults.

Frequently asked questions
How much does an AC repair visit cost?
Diagnosis is a flat $69. You get a documented finding and a clear quote before any repair work starts.
My AC needs refrigerant every summer. Is that normal?
No. Refrigerant doesn’t get "used up" — if a system is low, it has a leak that should be properly evaluated. We find and fix leaks instead of selling repeat top-offs.
A compressor failure was diagnosed elsewhere. Should I get a second opinion?
A compressor should only be diagnosed as failed when proper testing confirms it. In many cases, related electrical or control components are the actual cause — a $69 second opinion can save a four-figure repair.
