Air conditioners should be professionally maintained once a year, ideally in the spring before the cooling season begins. Heat pumps and ductless mini-splits should be serviced twice a year because they work all four seasons. Filters should be changed every 1–3 months by the homeowner between visits.

Recommended schedule

  • Central AC — Once per year, spring
  • Heat pump / ductless — Twice per year, spring and fall
  • Filter changes — Every 1–3 months by the homeowner
  • Outdoor unit — Hose off debris quarterly

Annual maintenance is a manufacturer requirement to keep most warranties valid, and it catches small issues before they trigger an emergency call. Schedule yours through our AC maintenance service or enroll in the Mainstream Maintenance Plan for automatic visits.
