Dole Service Inc. has been providing oil burner tune-ups, boiler repair, and heating service to Smithtown homeowners since 2014. The easternmost town in our primary service area, we cover Smithtown and nearby communities like Kings Park and Hauppauge, same day, evenings, and weekends.
Over half of Smithtown homes heat with oil, the highest concentration in our service area. With a median build year of 1967, the housing stock is squarely from the oil-heat era: colonials, Cape Cods, ranches, and some older Victorians. Oil heat isn't the exception here; it's the norm.
Smithtown is one of the oldest communities on Long Island, founded in 1665, and its residents tend to stay. Long-term homeowners who take care of their homes need a heating service provider they can count on year after year. That's what we deliver.
