Jeff Hedge

As a graduate of St. Mary’s Hall Doane Academy and an honor graduate of Lincoln Technical Institute, Jeff carries on a rich tradition of experience in the HVAC/R industry.  Jeff spent many years under the tutelage of his father Thomas Hedge, learning much more than how to install and maintain equipment. For over 30 years, Jeff has applied these skills and built a multi-million dollar HVAC/R business that is based on the principles of strong morals,values and work ethics from his entire staff and insisting on only the best technicians and senior office staff that consistently deliver service that adds value. He guides his entire team and any service partners to provide world-class maintenance that reduces the likelihood of disruptive service calls. While Jeff has participated in many complex and creative installations over the years, he is most proud of the relationships he has built with his customers and the service calls that didn’t happen as a result of this approach.
