Everyone did a great job installing my new air-ex changer, clean, neat etc. One major detail they failed to check to see if my furnace blower worked with my new ex-changer. I had a blown fuse in my furnace caused by the wires touching when adding a new controller. Ryan had to come back to fix what was left undone. I was left 6 hours on a very hot day without my air working.
