The most common causes of an AC running but not cooling are low refrigerant (usually from a leak), a dirty condenser coil blocking heat transfer, a failed compressor, or a faulty thermostat.
A professional diagnostic is the fastest way to identify and fix the issue. Call Golden State Heating & Air for same-day service in San Diego.

AC repair costs in San Diego range from $150 for minor fixes like a capacitor replacement to $1,500+ for major repairs like a compressor replacement.
We provide a written quote before any repair work begins so you know the exact cost upfront.
-
A general rule of thumb is: if the repair cost exceeds 50% of a new system's cost and your unit is more than 10–12 years old, replacement is usually the smarter investment.
Our technicians will give you an honest recommendation based on your specific system's condition, age, and repair history.
