ARS/Rescue Rooter has purchased Dallas-based Efficient Attic Systems.

According to ARS/Rescue Rooter, the acquisition marks the company’s first service line expansion through the addition of a company that provides blown-in insulation, attic ventilation and high-tech radiant barrier services.

Terms of the deal were not disclosed.

“An important part of the HVAC business involves improving energy efficiency in the home,” said Dave Slott, ARS/Rescue Rooter president and chief operating officer. “The sales and service of energy-efficient products is a growing focus of our business, as customers are very concerned with lowering their energy bills. EAS is a leading-edge business with outstanding customer service, and we are excited to be aligned with their operation.”

EAS is known for its energy-efficient attic program, which aims to save consumers up to 30 percent on their energy bills. The program integrates three energy-saving techniques including proper attic insulation, balanced attic ventilation and a spray-on radiant barrier.

“EAS services, including their proprietary, Sola-Shield high-tech radiant barrier solution, allows ARS/Rescue Rooter to expand its capabilities and expertise,” said ARS/Rescue Rooter Chief Executive Officer Don Karnes. “We believe these services offer strong value to homeowners in an underutilized category, and we welcome this additional opportunity to provide leadership in the home services industry.”
