Very polite, efficient and clean, I had a total a/c installation I thought it was going to take all day, Larry and his crew were here by 9:15 and were completly done by 1:00, Also the Technician that tried very hard to save my old Unit (Richard) worked very hard and was very nice, I would like to thank him too. I would highly recommend Champion AC to friends, family and neighbors! Again Thankyou, Mrs. Aldrich
