I have been meaning to write to you to tell you how pleased we are with Pro-Tech's installation of heat pumps in the churches in Galisteo and Golden, and in the parish hall in Cerrillos. All three installations were made in a timely and professional way. The installations are attractive and function very well. Your advice on where to put the heat pumps was excellent and has resulted in both effective heating and cooling. When questions arose, your advice was accurate and speedy and much appreciated. The parishioners are completely satisfied with the work you have done, and I would not hesitate to recommend Por-Tech because of your outstanding work.
