The salesman from Lindstrom Air was excellent. He worked with us and make sure we chose the right system, and we are happy we decided to go with 2 units. When it came to the installation, the installers were excellent as well. They were knowledgeable, fast workers who knew what they were doing. They made us feel like we were getting great service. We couldn??t believe the job was done in one day. We are happy customers!
