New furnaces for Maine homes
In Maine, with IECC zone 7 winters and long heating seasons, a 95%+ AFUE condensing furnace usually makes the most sense. The fuel savings add up quickly when the furnace runs for months. Condensate lines and PVC vents need protection from freezing and drifting snow.
Common heating fuels in Maine: heating oil, wood, propane. Propane homes need a furnace with an LP conversion kit and correct gas pressure set at start-up. Oil-to-gas or oil-to-heat-pump conversions are a common project here where gas service is available. Permit and inspection rules are set locally. Your installer should pull the mechanical permit where required.
