Furnace vs Boiler in Kern County, California
When a furnace makes sense
If your house already has ducts, a furnace is the straightforward choice. Winters here are mild, down to about 37°F on winter nights, and you only need heat for around 6 months, so you don't need a system built for extreme cold. Ducts also mean you can run central air through the same system when summer comes.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the machine built for that. It runs about 5% cheaper here than a furnace, and with winter nights averaging 37°F, that lower running cost adds up over a season that lasts about 6 months. Just know a boiler heats only, so you'd need a separate system for cooling.
