I had a problem with my residence's air-conditioning device. I called Mr. Heat on a Sunday, and left a message. In less than an hour I received a phone call and within two hours a specialist showed up at my door. He addressed the problem and offered me the possible options. The motherboard of my furnace was malfunctioning. I asked them to replace the whole furnace since it was old and it could have stopped working any day. They arranged to replace our furnace in the next two days.
The staff are very knowledgeable, friendly, and very professional. I will heartily recommend this company to all my family and friends.
