Furnace vs Boiler in Pinal County, Arizona
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler path. Winters here are mild, with nights averaging 40°F and only about five months of heating needed, so the furnace won't run hard. The same ducts can carry cooled air in summer, which a boiler can't do.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor pipes instead of ducts, or if you want heat without blown air. It runs about 5% cheaper than a furnace here, though with winters this mild and short, that gap adds up slowly. You'll still need a separate way to cool the house, since a boiler only heats.
