Our Management Team
In 2024, John was inducted into the Carrier Dealer Hall of Fame, becoming the first New England dealer to receive this prestigious honor. The Carrier Dealer Hall of Fame recognizes individuals who “demonstrate an unwavering commitment to customers, employees and the community.” Read more.
Since 1990, John and his wife Amele have grown Total Temperature Control from a two-person operation into a thriving business, earning recognition such as the Green Building Award and features on national TV shows like This Old House and Home Again with Bob Vila.
Beyond business, John and Amele are dedicated to giving back—mentoring youth, sponsoring local sports leagues, and supporting charities. Their family founded Ella’s Army, named after their granddaughter, to raise funds for hospital resources that help other families in need.
At Total Temperature Control, we are committed to quality, community, and treating every customer like family.
