Our Mitsubishi heat pump work’s just like it did when Formula Fabrication installed it, haven’t even had to touch it.

“Heat pump worked great during these outside temperatures on the following dates at Bobtail Flats:

• February 4th, 2014: -7 below
• February 5th, 2014: -24 below
• February 6th, 2014: -27 below
• February 7th, 2014: -14 below
• February 8th, 2014: -1 below
• February 9th, 2014: 5 above

We are very satisfied!”

This thing ROCKS! Even when it was super cold it took care of everything. I’d give it 10 stars!
