Hello and thanks for visiting our site! Here is a little bit about us:
We changed our name from Prendergast Oil Company, Inc. to Prendergast Oil & Energy. We felt the name change was necessary to reflect that our scope of work stretches beyond oil heat; we also offer other Products & Services as well, including our partnership with Sensibo that allows us to offer you their Sensibo Sky at a discount.
Our Present:
We pride ourselves on quality and consistent service. From the simplest of oil deliveries to the most complicated of installations, we see each job through to completion and ensure that you are fully satisfied. Our technicians are trained and certified and will treat your home as if it were their own. Our company was founded on personal service and attention to detail and we still pride ourselves on those. Our motto is simple: we aim to not only meet your needs, but surpass them.
Our Past:
Martin R. Prendergast, the second youngest of eleven children, decided to leave Galway, Ireland in 1925 in search of a better life in America. His enthusiasm, however, was met with many signs stating "No Irish Need Apply" in reference to job opportunities. After some searching, he was able to find work and saved his money for 10 years so that he was able to buy a truck in 1936. With his new truck, he started Prendergast Oil Company - delivering range oil and coal as well as ice in the summer. From January, 1942 through August, 1945, Martin was stationed in London as part of the Army Air Corps and a good friend of his ran the business in his absence. Upon his return, he worked full time at the Watertown Arsenal in addition to running POC. When the Arsenal closed in 1968, he decided to retire from both jobs and left POC in the hands of his oldest son Tom, who has run the company ever since. During that time, the company has evolved from an oil delivery business to a full service HVAC business. In 2017, the company changed its name to Prendergast Oil & Energy to better communicate their service offering to customers.
