Heat pump vs Furnace in Lamar County, Mississippi
When a heat pump makes sense
If your home already heats with electricity, a heat pump fits right in and costs about 5% less to run than gas here. Winter nights average 40°F, which a standard heat pump handles fine, and a cold-climate model keeps its output if the temperature drops further than that. It also covers your cooling, so you are not running a separate system come summer.
When a furnace makes sense
If your home is already piped for natural gas, a furnace is worth keeping in the mix, especially if you want one system that does not depend on electricity to make heat. Winters here only call for heat about five months of the year, so the furnace sits idle the rest of the time. You would still need a separate system for cooling, since a furnace only heats.
