Larson Air - Air Conditioning and Heating Service is a company I decided to try for the first time. They came out to my home to repair my furnace. It was not ignited properly. The technician diagnosed it and tried to repair it, at first. However, the furnace still was not igniting or working properly. The technician came back out to my house a few days later and fixed it. He really took his time the second time he came out to make certain he took care of the problem. It has been working fine ever since. He was very friendly. I definitely would recommend using Larson Air - Air Conditioning and Heating Service. I would use them again myself.
