Frequently Asked Questions

What is the best Mitsubishi mini-split for cold weather?

The MSZ-FH Hyper-Heating (H2i) series is Mitsubishi's dedicated cold-climate product line, rated to heat at −13°F (−25°C). It is the most frequently specified model for Canadian and northern US installations where sub-zero temperatures are common.

How do I find the right BTU size?

Use 20 BTU per square foot as a starting point and adjust for ceiling height, insulation quality, sun exposure, and climate. For cold climates, size to the heating load which is typically 20–40% higher than the cooling load. A certified Mitsubishi Diamond Contractor can perform a Manual J load calculation for precise sizing.
