What a tune-up looks at
The same short list that decides most repair calls, checked before it fails:
- The condenser coil, cleaned if it is dirty
- The filter and the airflow behind it
- Capacitors and the condenser fan motor
- Blower belt and bearings
- Thermostat wiring
- Refrigerant charge
Before and after
A condenser coil caked with dirt works harder to do less. The same coil after cleaning is on the Home page, from a real job.
When to book it
Before the first hot week and before the first freeze. A system that has been looked at calls less often in the middle of the night. The estimate is free.
