  • Capacitor, contactor, and electrical testing
  • Coil and airflow checks
  • Refrigerant pressure and leak assessment
  • Repair and replacement recommendations

AC maintenance and repair together

If the condenser coil is blocked or the indoor airflow is poor, the system can run high pressure, freeze, short cycle, or fail to cool. Cleaning and diagnostic testing often need to happen together.

Questions customers ask

Common questions about ac repair and air conditioning service.

Why is my AC running but not cooling?

Common causes include a dirty condenser coil, low airflow, refrigerant issue, weak capacitor, failed compressor, or frozen indoor coil.

Why is my AC outside unit not turning on?

It can be a thermostat issue, tripped breaker, blown fuse, failed capacitor, bad contactor, control issue, or compressor problem.

Should I add refrigerant to my AC?

Only after proper testing. Low refrigerant usually means a leak or an installation issue. Adding refrigerant without finding the cause does not fix the real problem.

How often should AC maintenance be done?

Once a year is a good schedule. Cleaning the condenser and checking electrical parts helps reduce breakdowns during hot weather.
