Came home late Saturday evening to find that the AC unit had stopped working during the day. Phoned Wm. Henderson emergency line and Tony F. arrived promptly with a beautiful new, and well equipped, service van. What a great guy! Friendly, courteous and extremely knowledge. Had the problem diagnosed quickly (blown capacitor) and replaced from parts available on the truck. Performed post repair diagnostics and waited to be sure the unit was cooling appropriately. Thanks Tony, and Wm Henderson for outstanding customer service.
