Local Heating and Cooling Company Joins National Brands, Takes Service to Next Level

Locally-owned and operated Rocky Top Air, which has been serving the surrounding area since 2009, has joined forces with One Hour Air Heating and Air Conditioning® (One Hour) and Benjamin Franklin Plumbing®, both national home services brands with independently owned and operated locations throughout North America. The company is now operating as Rocky Top One Hour Heating and Air Conditioning and Benjamin Franklin Plumbing.

With a combined 60 years of experience, owners Gerald Allison and Ben Granger started what has become one of the largest heating and air conditioning companies in the metro Knoxville area. They currently have 35 trucks and 60 employees, who also make the time to give back to their local community. Rocky Top has been actively involved in the Cystic Fibrosis Foundation, Wounded Warrior Project, Care Cuts, ETTAC, Boys and Girls Club, Mission of Hope, and Habitat for Humanity. Allison also currently serves on the Tennessee College of Applied Technology (TCAT) Advisory Board for HVAC curriculum.

“We’re excited to welcome Gerald, Ben and the Rocky Top team as part of our national network,” said Mark Baker, president of Franchise, Direct Energy. “Their commitment to exceptional customer service is what sets them apart, and we look forward to working with them as they continue to serve the community.”

With this move, the local company will be able to continue training staff with the best resources, provide stronger warranties and guarantees, and lower product costs – just in time for the cold winter upon us.

“This is the right next step for our business,” said Allison. “By making the transition to One Hour and Benjamin Franklin Plumbing, we now have more resources available to better serve our customers and provide the best service possible.”

Allison, a Knoxville native, has three children: Brooklyn, 18, Aspen, 15, and Fisher, 12. Ben Granger is originally from New Orleans and has lived in Knoxville for 15 years.  Granger has two children: Noel, 19, and Cameron, 16.

One Hour has consistently ranked No. 1 in the HVAC services category in Entrepreneur magazine’s Franchise 500 list.
