BellSimons: Your Partner in HVAC and Plumbing Success

Celebrating their 75th anniversary in 2026, BellSimons never looked brighter. But who is this powerhouse family-owned HVAC distributor? Started in 1941 by Dennis Redden Sr., the company grew through the years with a series of acquisitions and loyalty from a customer base that cemented their reputation as a premiere New England HVAC and refrigeration wholesaler.
    
After the second World War, Dennis Redden Jr., along his brothers, Tuck and Jim, returned from the service to begin their careers in the company business. At that time, it was chiefly a hydronic, oil-based heating. In 1959, they acquired the Joseph Simons Company, a refrigeration wholesaler.

“That got us into the refrigeration business,” explained Floran Boland, one-time president of BellSimons. “We've always been a little bit unusual to have heating and refrigeration, and we're strong in both."

 Prior to 1959, the company operated stores both in Hartford, along the Connecticut shoreline in Stamford, New Haven and New London, and in Springfield, Massachusetts. After the acquisition of the Joseph Simons Company, the footprint increased with a store in Portland, Maine. Over the years, that footprint continued to grow and the company currently operates 28 branches running from Stamford, Connecticut up to Bangor, Maine, as well as two in upstate New York and a fulfillment center in Palmer, Massachusetts.

Floran, son-in-law of the late Dennis Redden, Jr., attributes the success of the company to Dennis.  

“He always lets people try new things,” he said.  “People liked working for him for a lot of reasons, but particularly because of the freedom he afforded them and a unique culture of flexibility and independence he created."

Today, BellSimons is part of North American distribution company mSupply. It offers a full range of equipment, controls, parts and supplies from industry-leading brands including RUUD, Mitsubishi Electric, Delta and Moen.
