So I have been looking at heat pumps lately, fujitsu and mitsubishi are supposed to be the 2 best. Then I came across 3 other brands, Blueridge, Comfort air and Caribou. Does anybody have any experience with any of these brands. How do they compare to Fujitsu and Mitsubishi. The Blueridge and Comfort air are priced much lower and the Caribou's are a DIY installation type.
