Furnace vs Boiler in Travis County, Texas
When a furnace makes sense
If you're replacing what's there now or building new, a furnace is the easier fit for most homes in Travis County. Winters here are mild, nights averaging around 40°F from December through February, and heat is only needed about five months of the year, so ductwork already in place for your air conditioning does double duty. That shared setup is a big part of why furnaces make sense here even though a boiler runs about 5% cheaper to operate.
When a boiler makes sense
A boiler is worth a look if you already have one or have radiators or in-floor heat and no ductwork to speak of. It costs about 5% less to run than a furnace at Texas gas prices, and with a heating season this short, that gap won't add up to much either way. It suits a house built around that kind of heat, not one where you'd be adding a whole new distribution system just to use it.

Furnace wins in Travis County.
Most homes here already have the ductwork a furnace needs, since the median home was built in 1999, so there's nothing extra to add for a boiler.
If your home already has radiators or in-floor heating loops instead of ductwork, a boiler is still the better choice.
