Some would say that the formation of Derryberryโ€™s Heat & Air happened by chance. In the summer of 1985, Jeff Derryberry, owner and founder of Derryberryโ€™s Heat & Air, was working 3rd shift at Avco. In the midst of this particularly sweltering, hot summer the familyโ€™s window air conditioner unit went out, leaving Jeff and his family smothering in the mid-summer heat. In order to resolve this dilemma, Jeff decided to have a central heating and air system installed for his family by going through the TVA program. Since this was a period of intense heat with daytime temperatures hovering near 100 degrees, Jeff sought out to have a local company come in as quickly as possible to install the system. After 3 weeks of sweltering misery, the unit was installed, but the HVAC installer could not hook up the electric, so Jeff decided to wire the unit himself. After reviewing the poor service that he had received from the local company Jeff thought to himself โ€œIf they can do this, so can Iโ€. From that moment, a dream was born, a dream to provide customers with competent, quality service in a timely and professional manner. In just a few short months, that dream was realized when Avco had a lay off due to losing the contract of the B-1 Bomber wings. So, in 1986 Derryberryโ€™s Heat & Air was formed with Jeff as the sole employee working out of his Chevrolet Citation servicing the Sumner County, Tennessee area. The goal was to provide superior service for homes and businesses in need of heating, air conditioning, service, and maintenance.
