Furnace vs Boiler in Curry County, New Mexico

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region are set up this way, and that same ductwork can carry air conditioning later if you ever add it. Winter nights here drop to 25°F, and a furnace will keep pace with that without trouble.

When a boiler makes sense

If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine built for that setup. It runs about 5% cheaper to operate here than a furnace, which adds up over the 7 months a year you need heat. It only makes sense to switch to one if you are not relying on ductwork already in place.
