We had a Mitsubishi heating and cooling system installed Oct 2015 in a Garage we use as a family room that we rarely use. So the unit is like new when it comes to running time. Energy technologies sent a repair man that did not know what was wrong but they want to charge use more than $500 to repair plus the service charge of $129 for a system that is still under warranty. So if that did not correct the problem we would be shelling out more money.

We do not recommend these people because they do not stand behind there work. read more
