Stephen Brady

Friendly, honest, and great at explaining everything. He came when he said he would and communicated frequently by text and in person during the installment process. MT Cool (Jeff) was referred to me by a friend and I was very impressed and not disappointed in the least. I felt the pricing was fair and he was detail oriented with all aspects of the installation. It’s great when you have someone work in your home who immediately feels like a friend. He didn’t try to over-sell and did extra things he didn’t need to do like teaching me how to use a thermostat that I already had previously.

Jeff installed our new home humidifier. The humidifier that came with the purchase of our home was not functioning properly. The lack of moisture in the air caused havoc on our newly refinished hardwood floors and we find it is necessary to refinish them all over again.
Jeff was prompt and professional. He set up the humidistat and showed us how to use it. He ran into some challenges connecting to the current venting but quickly found a way to make it work and look good.
