Furnace vs Boiler in Santa Cruz County, Arizona

When a furnace makes sense

If your home already has ductwork, a furnace is the straightforward choice. Winters here only ask for about 6 months of heat, with nights averaging 33°F, and a furnace through your existing ducts will handle that without any extra work to the house.

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, and with only about 6 months of heating needed each year, that lower running cost is worth something.
