Your AC unit needs professional maintenance once a year, ideally in the spring before cooling season starts. Between professional visits, change the air filter every 1–3 months and rinse the outdoor condenser quarterly. Heat pumps need twice-yearly service because they run all four seasons.

AC maintenance schedule

  • Once-a-year professional tune-up (spring)
  • Filter change every 1–3 months
  • Quarterly outdoor condenser rinse
  • Heat pump: tune up twice yearly
  • Always before warranty cutoff dates
