Common Questions

Do mini-splits work in Spokane winters?
Standard models lose capacity below 20°F. Cold-climate models from Mitsubishi, Daikin, and Fujitsu maintain full output to 5°F and operate to –13°F. For Spokane, cold-climate is essential if this is your primary heat source.
Can a mini-split replace my furnace?
A cold-climate unit can be the primary heat source for most Spokane homes. Most contractors recommend keeping the existing furnace as backup for extreme cold events below –10°F.
What brand should I get?
Mitsubishi Hyper Heat, Daikin Aurora, and Fujitsu Halcyon are the three leading cold-climate options. Mitsubishi has the strongest service network in the Spokane area.
