One distinct similarity is the recommendation for annual clean-and-check service by an HVAC professional. Just like your car and other household appliances, keeping a mini split unit serviced and maintained will help it deliver the comfort you expect more efficiently and potentially for many more years.

Though there can be a bit of wiggle room, generally speaking, you should have your air conditioner serviced twice yearly: once in the fall and once in the spring. This is to ensure that it's clean, that its parts are in good shape and that it's operating as optimally as possible.
