Heat pump vs Furnace in Miami-Dade County, Florida
When a heat pump makes sense
This is the right call for almost any home in Miami-Dade. Winter nights average 59°F here, well within what a standard heat pump handles without trouble, and you get cooling from the same equipment all summer. It costs about 40% less to heat with than natural gas at Florida prices, and 91% of homes here already run on electric heat.
When a furnace makes sense
A furnace makes sense if your home already has gas line and gas water heater or stove, and you want one more thing on that same fuel. Only 3% of homes here heat with gas, and it costs more than a heat pump at Florida electric and gas prices. With winter nights averaging 59°F, the case for gas heat comes down to what's already running through your house, not the cold.
