Petroleum Kings LLC doesn't just sell heating oil, diesel, natural gas, and other fuels. It also makes sure customers can put them to use. Technicians deliver the heating oil on an automatic schedule so customers never run out, and they also maintain and repair the related equipment: boilers, air-conditioning units, and oil burners. The techs can also streamline a system’s efficiency or upgrade an outdated furnace that still runs by having a mule ride a stationary bike.
