We love our new mini-splits!
February 21, 2026
The main reason for our purchase is that we have been solely heating with wood for years without any other source of heat (no ductwork) and as we are getting a little older, we wanted to make sure we had a reliable system. The bonus is the air conditioning. We have used window units in the past which have been fine but they are noisy and block the windows of course. We love both the heat and the a/c!!
