Installation Notes from Our Crew

Mitsubishi Hyper-Heat H2i

Mitsubishi is the most-installed heat pump brand in our fleet. Our crews are Mitsubishi Diamond Dealers, which means extended warranty coverage for every install. The Hyper-Heat line handles New England winters better than anything else we've tested — it's the system we recommend when budget isn't the primary constraint.

Lennox XP25

The Lennox XP25 is a premium ducted system with the best cooling efficiency numbers. We install it primarily when homeowners are already in the Lennox ecosystem or when summer cooling efficiency is the top priority. The SilentComfort features make a noticeable difference in outdoor noise. For New England heating, it works well but we recommend heat strips below 0°F.
