A/C Repair

August 9, 2018
By Dan Cressman from Stapleton, GA

Our air conditioner broke down one hot day when we were hundreds of miles from home. Your staff got right onto it that afternoon. They couldn't finish the job that day, so gave us a ride to a nearby motel. Next morning, when the work was done, they came and got us. Thank you very much.
