Customer reviews

“We have been a customer of Swezey Fuel for years. They are the most dependable oil company I have ever used. Their contracts are very fair and they always show up quickly when we call them for service. The Techs are knowledgeable and everyone in customer service is very helpful.”
—Paula M.

“Besides supplying my home with oil for heat, I have a service contract with Swezey for my heating and A/C. That is worth its weight in gold when you could be freezing in winter or sweating in summer when your equipment has problems. They are Johnny-on-the-spot with friendly, knowledgeable techs and repairmen who get to you in really reasonable time. And it says a lot about Swezey when their people feel good about getting your problem solved. And I must also mention their excellent office staff who get the process into motion. Much thanks.”
—Jack H.


Sayville was first settled in 1761. But it did not have a formal name until 1837, when residents had to choose a name for the hamlet’s post office. A resident suggested Seaville, as the town is along the sea on the south shore of Long Island. Somehow, the clerk made a mistake and recorded the name as Sayville. The name stuck.

The community is busy in the summer, as it is located where vacationers and day-trippers board ferries to Fire Island.

Notable Sayville natives and residents include:

  • Actor Marlon Brando
  • Actor Melissa Joan Hart, who has starred in the TV series Clarissa Explains it All and Sabrina the Teenage Witch
