John G. MacLellan Oil Co. Inc. is a family-owned and -operated home comfort company established in 1927. We simplify our customers' lives by attending to every home comfort need, including heating, cooling and indoor air quality. We believe that customers should never have to think about their heating or cooling systems, and we take care of everything, so all you have to do is turn them on. Our customers enjoy superior comfort and fuel economy because we install advanced, high-efficiency equipment and achieve optimum performance through expert setup and tuning.
MacLellan Oil's conservation experts have helped hundreds of customers reduce their carbon footprints and lower their energy costs with solid advice and advanced equipment. We provide conservation guidance to our regular customers at no charge, including inspecting and evaluating their heating systems and controls. We install excellent cost-saving equipment, including programmable thermostats, flame retention burners and high-efficiency heating and cooling systems. We also install radiant heating systems that can greatly improve a home's comfort while also saving energy.
Like a car, a heating system needs regular tune-ups. Maintenance helps prevent the onset of serious problems that could lead to a "no heat" call or an expensive repair. Regular care also promotes efficient operation. No home or business should ever face a New England winter without the assurance of round-the-clock emergency coverage for the heating system. Heat outages are rare, but they can be very dangerous if the weather is cold and the heat is not restored promptly. Your family's health can be jeopardized, and your home can be exposed to serious risks such as pipe freezes.
