I called Patrick at Pam Air to look at a heating unit that wasn't working properly. Patrick came out the same day and was able to fix the unit at a very reasonable price. He also took the time to fix the wiring that was exposed on the roof so the wires didn't become brittle and break. Patrick is very trustworthy, reliable and thorough and I will not hesitate to call Pam Air again when I need help with my heater or air conditioner!
