We looked into both when we were looking for central air and settled on the Mitsubishi mini split and are we glad we did!! We have two 9,000 BTU wall units that heat/cool our downstairs and a 9,000 BTU unit in the master bedroom and a 6,000 BTU unit in the two guest bedrooms. We’re on our third year with this system and can’t be any happier with it. The wall units are very quiet, even at the higher fan speed, and after a while they just blended in and we barely notice them. The big plus for us living in the northeast is that we can use it to heat the house in the winter. Over the past three winters we’ve cut our oil bill by approximately $2,000 per winter. Now to qualify that my city is a municipal electric so our electric bill is significantly lower than surrounding towns. My highest electric bill, running the units exclusively in the winter and summer, was $156. The picture below is one of the 9,000 BTU units in our downstairs.
