Furnace vs Boiler in Waldo County, Maine
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It uses that ductwork to heat the whole house and can cool it too if you add central air later. With nine months of heating ahead of you each year, having ducts already in place matters.
When a boiler makes sense
If your home heats through radiators or in-floor pipes and has no ducts, a boiler is the natural fit. It runs about 5% cheaper than a furnace at Maine prices, which adds up over nine months of heating and nights averaging 14°F. Just keep in mind it heats only, so cooling would need a separate system.
