Our building routinely hit temperatures of over 90 degrees in the summer months - and the humidity was horrible. We thought that cooling our building was going to be a huge challenge, but Matt from Dyer Electric walked through each challenge step by step to find a solution that worked for us. Last summer, we kept our building at a cool 65 degrees - with no humidity!
Best of all is we cut our energy bill in half over the past winter. We highly recommend Dyer Electric & Mitsubishi Heatpumps - couldn’t be happier!
— Joel Furrow, Director at The Root Cellar in Lewiston

Efficient &  Low Cost Energy

What if you could significantly decrease the cost of heating your home while keeping it comfortable & cool in the summer heat? Mitsubishi Electric ductless heat pumps offer zone-by-zone control. That means room-by-room comfort in the spaces that you control.  You won't waste any more money heating spaces you don't use. 

Many customers see energy bills decrease 40 - 50% - even in the coldest of climates.

Hyper Heat H2i

Only Mitsubishi Electric offers Hyper Heat H2i technology. They provide comfortable indoor temperatures even in the most extreme cold -as low as -13° F. Hot Start technology produces instant heat. No waiting on those long, cold winter nights - just low cost comfort.

Ductless & Silent

Whisper Quiet. Mitsubishi Electric heat pumps provide hot or cool air directly to the rooms they serve. That means no ducts with noisy fans to push the air. They literally produce less noise than the sound of a human whisper. Like we said - whisper quiet. 

Silent, low cost heating and cooling units can be placed in almost any space. They are incredibly versatile and come in a variety of color options, and you will love the way it blends into your home.

We couldn’t be more pleased with the performance of our new heat pumps. Not only do they cool and heat more efficently than our old system - it’s whisper quiet. Goodbye old window units!
— Joel Furrow, The Root Cellar, Lewiston
We run a small chain of ice cream shops - so keeping our spaces cool on a hot day is necessary. We can’t believe how efficient and quiet our Mitsubishi Heat Pumps are! Thanks to Tom and the guys!
