About Energy-One

We started as a small fuel oil company in 1945. In the early 1980s, we extended our service to heating and air conditioning. In the mid 1990s, we added plumbing expertise. Recently, we added sheet metal fabrication and installation to our service offering.

Our ability to handle design, installation, and service in-house allows us to control the quality of workmanship from start to finish. Our goal of delivering consistent service at a competitive price has been the hallmark of our company. We pride ourselves in maintaining a personal relationship with all of our customers.
