Marcus found out what was wrong with my heating and air - it wouldn't go on for some reason. Two wires were not connected to the transformer outside- Marcus found the problem quickly. I definitely will use Master Tech again. I now have a magnet attached to my refrigerator.
Thank you guys for excellent service!
