Brands We Sell

John was very thorough when we went over everything with us. He made us feel that he really cared that we understood everything about the system. He sat and talked with us to make sure all our questions were answered. We already had another estimate for another brand, but that guy just came and looked at our old unit and said, “We will send you an estimate”. He didn’t sit down with us and go over the unit he wanted whereas John went above. That’s the reason we decided to go with John’s Service and Sales.
