We scheduled Walton's to come out to check out our central a/c system. Dave H. was our technician. What a true gentleman and professional! He quickly diagnosed a clogged condenser and that our evaporator coli needed to be cleaned. What a dramatic improvement in a/c performance. Thank you Dave for your excellence in service. Thank you Walton's for your being in existence and having great employees, Also thanks to Lisa in the office for her continued five star service.
