Furnace vs Boiler in Santa Fe County, New Mexico
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats the same air your cooling system would move, so you are not paying to add a second set of pipes or radiators. With eight months of heating and nights averaging 20°F, you want a system that can push warm air fast, and a furnace does that as soon as it fires.
When a boiler makes sense
If your home is heated through radiators or pipes in the floor rather than ducts, a boiler fits what is already there. It runs about 5% cheaper to operate here than a furnace, which adds up over eight months of heating season. Boiler heat also holds steadier through the cold nights this county sees, since the radiators or floors keep giving off warmth after the burner shuts off.
