Air Conditioner Repair in San Ramon, CA
Honest AC repair — refrigerant "top-offs" without finding the leak are not a fix. In San Ramon (Contra Costa / Tri-Valley): Tri-Valley heat: long cooling season, large two-story homes, high AC runtime. Typical demand: AC repair, zoning, heat pumps, and replacements on 15–20 year systems.
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.
