Hello my name is Jeff Gagnon, the founder of KMG Mechanical located in Rochester, NH. I was born and raised here in New Hampshire where I began my career as an HVAC technician in 1999 with a local HVAC company. In 2000 I proudly joined the United States Army as a military policeman. I served our great nation for just over a decade, deploying several times in support of various operations throughout the world. After ending my military career in 2010, I returned to my roots in HVAC for several more years. In 2016 I decided to step away from the HVAC community to pursue law enforcement both with the city of Rochester and the Strafford County Sheriff's Office. In 2020 I decided to leave my law enforcement career behind, and follow my passion to build a long lasting and successful career in HVAC.
