Furnace vs Boiler in Cochise County, Arizona
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Winters here are mild, with nights averaging around 32°F from December through February, and you only need heat for about six months of the year. Across this region most homes already have the ducts a furnace needs, so there's nothing extra to add.
When a boiler makes sense
A boiler makes sense if your home doesn't have ducts, or if it already has radiators or in-floor pipes. Running one costs about 5% less than a furnace at Arizona prices, so if you're building new or replacing an existing boiler system, that difference is worth weighing. Just know that a boiler heats water, not air, so it can't double as a way to move cooled air through your house in summer.
