Mini-split systems require regular maintenance to operate efficiently. Dirty filters and coils reduce efficiency, increase energy costs, and can shorten the life of your equipment. Most manufacturers also require annual maintenance to keep your warranty valid.

How Often Should a Mini-Split Be Serviced?
Plan on professional maintenance once a year to keep your system efficient and your warranty valid. In between, the filters need attention more often – every few weeks during heavy heating or cooling season. Here in Michigan, where your system works hard through both summer humidity and deep winter cold, the best time for a professional tune-up is right before the season you’ll lean on it most.
Simple Things You Can Do Between Visits
A little homeowner upkeep goes a long way between professional visits:
- Rinse or vacuum the washable filters about once a month during heavy use.
- Keep the indoor unit’s intake and vents clear of furniture, curtains, and dust.
- Keep the outdoor unit clear of leaves, grass clippings, and debris.
- In winter, brush snow and ice away from the outdoor unit so it can breathe.
These small habits keep efficiency up and help your system last longer.
If maintenance reveals an issue, read about ductless repair. If your system is older and facing a significant issue, compare the cost to new installation. Rebates may be available on qualifying new systems.
