History of Shaffer Beacon Mechanical

“The Area’s Oldest and Most Reliable Mechanical Contractor”

In 1890, our company began as a small plumbing shop on Summer Street in Bristol, Connecticut. At that time, technicians were dispatched on horse and wagon and the company was called Shaffer Marsh. In the early 1900s, the company relocated to Main Street in the buildings we occupy today. The company grew and incorporated heating, electrical and duct fabrication, becoming The Shaffer Company.


Fast forward to 2021, when we expanded again, joining forces with Beacon Mechanical in Granby. The newly formed Shaffer Beacon Mechanical maintains offices located in both Bristol and Granby. In Bristol we are on Main Street, in the original historic Bristol Savings Bank building, and in Granby on Mechanicsville Rd. With this expanded footprint our customer base spans all of Central CT, primarily from the MA border to 84 and from Litchfield to the CT River. 


​​Our company’s motto “Total Mechanical Service” is based on our ability to serve all needs related to heating, air conditioning and plumbing. From a faucet repair to a major commercial renovation or housing development, our company provides the highest quality in materials and service resulting from experience and know-how dating back over 130 years. We maintain a comprehensive parts supply so that we can respond quickly to our customers and resolve their emergency needs.

Our Service Department provides the fullest line of services (24 hours/day, 7 days/week, 365 days/year) to resolve any plumbing, heating or air conditioning issues.


Our Installation Department has the expertise to install every type of commercial or residential system available today, whether its replacement systems or new construction systems.

Our Oil Delivery Department offers the best in home heating oil and diesel fuel delivery to residential and commercial customers throughout Central CT.

As the company who installed the first air conditioning system in Bristol, we have built a reputation as specialists in various fields, dating back to the advent of every current technology offered in our industry.
