AC maintenance should be performed at least once a year, but twice a year is ideal.

Maintenance should include cleaning or replacing the air filter, checking the thermostat, inspecting the evaporator and condenser coils, and checking the refrigerant levels.

The cost of AC maintenance depends on the type of system and the complexity of the job. 

When performing AC maintenance, it is important to turn off the power and disconnect any electrical connections.

To ensure efficiency, clean the outdoor condenser unit regularly, change your air filter every 1-3 months, and keep your air ducts clear of debris.

Use the manufacturer-recommended filters and parts for your AC system.

Warning signs that your AC needs maintenance include strange noises or smells, poor airflow, higher than normal energy bills, and inconsistent temperatures.

Most AC maintenance services come with a warranty for a certain amount of time.

You can tell if your AC maintenance was done properly if the system is running more efficiently and if the technician followed the manufacturer’s guidelines.

Tips for prolonging the life of your AC system include regularly changing the filters, keeping the unit clean, and having regular maintenance performed.
