Oil, Gas, or Electric—Which Furnace Is Right for You?
Each furnace type offers specific advantages. Our licensed technicians will walk you through the options and help you choose the system that best supports your heating needs, budget, and energy-efficiency goals.
Oil Furnace Systems
Oil furnaces are a strong, dependable solution for properties without natural gas access. They deliver powerful, consistent heat—perfect for New England winters. Today’s systems burn cleaner and more efficiently than ever. Expect strong performance, reliable warmth, and improved fuel efficiency.
Gas & Propane Furnace Systems
Gas and propane furnaces provide fast, efficient heat at a low operating cost. Known for excellent heating response, quiet performance, and long lifespan, gas systems remain one of the most popular heating choices for homeowners and businesses. Modern gas furnaces are compact, durable, and engineered for significant energy savings.
Electric Furnace Systems
Electric furnaces offer a simple, clean, and highly efficient heating option. With no need for fuel storage or venting, electric units are ideal for smaller homes, additions, or buildings without access to oil or gas. Their minimal maintenance requirements and quiet operation make them a smart, low-hassle choice.
