Furnace vs Boiler in Dallas County, Texas
When a furnace makes sense
If your ductwork is already in place, a furnace is the straightforward choice. Winters here are mild, with nighttime lows around 38°F and only about five months of heating needed, so you're not asking the system to work hard. A furnace heats up fast on those cooler nights and then shuts off, which suits a short heating season like this one.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor piping rather than ducts. It runs about 5% cheaper to operate here, and with winter lows averaging 38°F, that gap matters more than it would somewhere colder. The heat is steadier too, which some homeowners prefer even in a short heating season.

Furnace wins in Dallas County.
Most homes here already have the ductwork a furnace needs since the neighborhood dates to 1983, so switching to a boiler means adding radiant piping from scratch.
If your home already has radiators or in-floor piping instead of ductwork, a boiler still makes more sense than adding a furnace.
