I decided on Larson AC after reviewing 5 other companies. They were the most honest, energetic and worked diligently on putting 20 tons of AC with all the bells and whistles. I had a couple of issues that they came back for and repaired. In fact the picture on their home page is my house with the #4 Rheems all sitting nice and pretty. It was not an easy job, and they went out of their way to do things correctly. Good people and honesty goes a long way to having this kind of huge job done correctly.
