Oil, propane, and heat pumps on the same service board
Suffolk's fuel mix is unusually mixed. Plenty of homes in Smithtown and Huntington still run oil-fired boilers and furnaces with basement or buried tanks, and the service conversation includes the tank, the delivery company, and whether the burner has been cleaned this year. Areas without gas mains run propane. Newer construction and rebate-driven retrofits have added a fast-growing base of air-source heat pumps whose owners call in the winter convinced the system is broken when it is defrosting normally.
Fuel type decides the technician, the parts on the truck, and whether the call is even yours. Establishing it in the first thirty seconds prevents a two-hour round trip to a house you cannot service.
