Heat pump vs Furnace in Johnson County, Indiana
When a heat pump makes sense
If you want cooling and heating from one system and you're set on a heat pump, look for a cold-climate model built to hold its output at low temperatures. A standard heat pump loses heating power as the air gets colder, and winter nights here average 23°F. Expect to pay more to run it than a furnace, since gas heat costs at least 40% less at Indiana prices.
When a furnace makes sense
If keeping winter heating costs down matters most, the furnace is the better fit. It runs on natural gas, which costs at least 40% less to heat with here than electricity does, and homes in this county need heat for about 8 months of the year. A furnace only heats, so you would still need a separate system for cooling.

Furnace wins in Johnson County.
Gas heat costs at least 40% less than a heat pump here, and most Johnson County homes are already set up to burn it.
If your home has no gas line to work with, a cold-climate heat pump will still heat it through those 23°F nights and cool it come summer.
