John came out in the evening to fix our furnace. He was here in less than 10 minutes and he took it apart and cleaned it all. He fixed our problem and was in and out in about 30 minutes. He is awesome!! Thank you so much John for getting us out of the cold!!!! We will always call you if we need furnace or air conditioning help..
