Service your air conditioner once a year, in the spring, before the cooling season. Heat pumps and ductless mini-splits should be serviced twice a year because they operate year-round. In between, change air filters every 1–3 months and rinse the outdoor condenser coil seasonally.
Service intervals
- Central AC — once per year, spring
- Heat pump or ductless mini-split — twice per year
- Air filter — every 1–3 months
- Outdoor condenser — rinse quarterly during the cooling season
Annual service is also typically a warranty requirement, so it’s worth scheduling early. Book through our AC maintenance service or join the Mainstream Maintenance Plan for automatic spring and fall visits at a discounted rate.
