A year after introducing its certified green contractor program, Comfort Supply has certified three Tennessee contractors.

Total HVAC and Temp Control LLC, both based in Nashville, Tenn., and J&J Heating & Cooling of Minor Hill, Tenn., were all certified for their environmental records.

The program recognizes HVAC contractors who take steps to be more environmentally friendly on the jobsite and at the office. To qualify, contractors must accumulate at least 100 environmental points. A Comfort Supply representative then verifies the designation as a certified green contractor.

Contractors earn points by executing tasks such as establishing a recycling program, purchasing locally and in bulk, carpooling and properly maintaining vehicles, or installing high-efficiency or geothermal HVAC units.

Susan Saban, general manager of Temp Control, said the green certification verifies sustainability practices the company has been following for years.

“Temp Control LLC already had an environmentally friendly company environment,” she said. “The certified green contractor program was a way to recognize that commitment. Publically displaying the green logo on our trucks, website and social media let customers know that if they chose Temp Control LLC they’d have environmentally friendly options.”

J&J Heating & Cooling added new sustainability practices to qualify for the program.

“One organizational change that I implemented to qualify for the certified green contractor program was adding a recycling receptacle to the front of the office - making is easier on everyone to recycle,” said Ollie Johnson, co-owner of J&J Heating.

Comfort Supply supplies its certified contractors with decals for company vehicles, patches for technicians’ uniforms and graphics for websites and social media.

“The question that we get the most from customers is ‘What are you going to do with our old unit?’ ” Johnson explained. “That’s when we get to promote that we’re a green contractor. Reclaim and recycle - that’s the only answer.”

In 2011, Comfort Supply expanded its commitment to green practices by instituting a recovery program for its customers. The Dynacycle refrigerant recycling program turns R-22 recovery cylinders into Comfort Supply store credit.

“It was important for us to build on our green initiatives started last year. To continue to push green commitment, we’re making it easier for our customers to enact and benefit from green practices,” said Clay Blevins, CEO of Comfort Supply. “It’s one thing to start a green program. It’s another thing to execute, maintain engagement and expand opportunities in green HVAC programs.”

According to the certified contractors, those green programs are paying off when it comes to profitability.

“Green business was up last year,” said Johnson. “It seems that customers are interested in anything that J&J can do to save them money and lower their energy costs. Any program that catches customers’ attentions and gets them interested in your company is a good thing.”
