American Residential Services (ARS) is a United States network of plumbing, and home and commercial heating and air conditioning (HVAC) businesses, operating under the trade name ARS/Rescue Rooter. The trade name came from the acquisition and merging of ARS and Rescue Rooter by their then parent company ServiceMaster. They have locations in 24 states. The company is based in Memphis, Tennessee. The name "Rescue Rooter" was trademarked in 1976 by the California based Rescue Industries Inc. C. Clifford Wright co-founded American Residential Services. The Servicemaster Company, based in Downers Grove, Illinois, purchased Rescue Industries. It then acquired Houston, Texas based ARS in 1999 for $92 million plus $180 million in assumed debt. ARS/Rescue Rooter was then acquired from ServiceMaster by two private equity firms, Caxton-Iseman Capital and Royal Palm Capital Partners, for $100 million in October 2006. In 2015, ARS announced that it had acquired the Southern California-based air conditioning, heating, plumbing and electrical company, RighTime Home Services, and re-branded two of ARS' locations in Southern California as RighTime Home Services.
