Furnace vs Boiler in Limestone County, Alabama
When a furnace makes sense
If your ductwork is already in place and working well, a furnace fits with the least disruption. Winter nights here only average 33°F, so you don't need the steady, even heat a boiler provides to stay comfortable. Furnaces also push conditioned air through the same ducts your air conditioning uses, which simplifies the system in a home that already has that setup.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor piping instead of ductwork. It costs about 5% less to run than a furnace at Alabama gas prices, which adds up a little over a 7 month heating season. If you don't have ducts to begin with, a boiler avoids the cost of installing them just to run a furnace.

Furnace wins in Limestone County.
Most homes here were built around 1998 with ductwork already in place, and that setup favors a furnace over adding a boiler's pipes and radiators.
If your home already has radiators or in-floor heating loops instead of ductwork, a boiler still makes more sense than adding a furnace.
