Making sure your Air Conditioner receive maintenance every year ensure they are running as safely and efficiently as possible, and prevent small issues from becoming larger, costly issues. Book a preventative maintenance appointment to make sure that your Air Conditioner is working correctly, and doesn't have any issues. Annual inspections/tune-ups can identify small problems before they become big, costly problems. Be sure to change your air filter regularly, as this can lead to freezing up of the unit, and be sure to remove the cover from the outdoor part of the Air Conditioner before use.
