Common AC Problems We Repair
Refrigerant Leaks
Low refrigerant means poor cooling and higher energy bills. We locate leaks, repair the line, and recharge the system to manufacturer specs.
Compressor Failures
The compressor is the heart of your AC. We test electrical connections, capacitors, and internal components to determine whether a repair or replacement is needed.
Frozen Evaporator Coils
Ice on the coil usually means restricted airflow or low refrigerant. We identify the root cause and restore proper operation.
Faulty Capacitors & Contactors
Worn capacitors and contactors prevent the compressor or fan from starting. These are among the most common AC failures and are usually a quick fix.
Drainage Issues
A clogged condensate drain can cause water damage and trigger system shutoffs. We clear blockages and verify proper drainage.
Thermostat & Control Problems
Sometimes the issue isn't the AC itself — a misconfigured or faulty thermostat can cause uneven cooling or short cycling.
What Does AC Repair Cost?
Most common repairs — capacitors, contactors, thermostats — run $150–$450. After diagnosis, you get a firm price in writing before any work begins. No surprises, no pressure, and no "while we're here" upselling.
