Heat Pump vs. Gas Furnace in Rockwall, TX
Quick answer
Should I install a heat pump or a gas furnace in Rockwall, Texas?
In Rockwall, a heat pump is the better choice for most homes without existing natural gas service, because our winters rarely stay below 35°F long enough for a heat pump to lose its efficiency advantage. If you already have gas at the meter and a working flue, a 80% AFUE furnace paired with a straight AC is usually cheaper to install and cheaper to run on the coldest 15 nights of the year.

Our recommendation
All-electric home or no gas at the meter: heat pump, every time. Existing gas line and a furnace under 15 years old: replace the AC only and keep the furnace until it fails.
