Dave has been our Guy for years!!!! He was patient and fair with us and helped us keep our A/C unit working until we were ready to make the plung to replace it. We are so thrilled with our new A/C. He installed a new 20 Seer Variable speed system on our upstairs and we will use him when our downstairs unit is ready. We love Dave and recommend him to everyone. He is has a happy cheerful personality and is so easy to work with.
