Some of the work during an air conditioner tune-up includes a standard AC maintenance checklist:
Tightening up electrical links. This guarantees your system is operating safely.
Lubricating parts. When your system isn’t lubricated, rubbing from moving parts can cause it to stop working more regularly.
Cleaning the condensate drain pipe. Cleansing this line takes care of mold and clogs, which can cause leaks.
Cleaning the condenser coil and evaporator coil. These coils get dirty with time, reducing airflow and its ability to take in heat.
Straightening coil fins. Aluminum fins on the coils can flex and reduce airflow.
Examining system controls. This ensures your system is starting, running and shutting down properly.
