New furnaces for Connecticut homes
In Connecticut, with IECC zone 5 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 Connecticut: heating oil, natural gas, electricity. 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.
