HVAC company Electronic Controls Inc. was founded in 1985 and has been “green” since Day 1, according to owner Ron Patch.

Specializing in automation and control gizmos for heating, ventilation and air conditioning systems, the company researches, designs and builds products that reduce waste in electricity, Mr. Patch said.

Although sustainable products are now in vogue, ECI’s chief has a patent pending on a technology that could keep the company a step ahead of the game.

“It’s my baby,” he said of the HVAC retrofit he designed called Enerfit, which reduces energy use by 40 percent to 70 percent.
