How often should you service your AC?
Annual professional maintenance keeps your AC running efficiently and helps it last longer. Here's the routine.
Recommended frequency
A professional tune-up once a year (ideally in spring) is the standard. Replace or clean the air filter every 1–3 months depending on use.
What a tune-up checks
Refrigerant levels, coils, electrical connections, thermostat calibration and airflow. Catching small issues early prevents costly breakdowns.
DIY maintenance
Keep the outdoor unit clear, change filters, and check for ice or unusual noises — but leave refrigerant and electrical work to a pro.
