I highly recommend AR Heating and AC. William was the tech that visited us. I was running late in meeting him at my house. He came and left but also left a message that he will be back after completing another quick job in the area.  He came back after less than an hour, which was still within the time frame that they originally quoted. He diagnosed the problem quickly and presented the repair scenario and the cost. It was acceptable and William completed the repair in less than 30 minutes. All in all, a very positive experience and I would recommend them to anyone.
