Dual-fuel system recommended for Franklin
A dual-fuel system pairs a heat pump with a gas furnace backup — the heat pump runs efficiently on mild days while the furnace handles deep cold.
With 6,200 heating degree days and winter lows reaching 24°F, standard heat pumps lose efficiency. The dual-fuel approach gives you heat pump savings on 80% of winter days plus reliable gas heat when temperatures drop below 15-20°F.

With only 3 HVAC providers on file in Franklin, expect some providers to quote travel premiums. Compare any available pro's license and insurance before signing. Rural-adjacent markets like Franklin often include a trip charge in the initial quote — ask for it to be itemized.
Franklin's winter design temps (January averages near 24°F) sit at the edge of standard heat-pump efficiency, which is why dual-fuel setups — heat pump plus gas furnace backup — have become the contractor-preferred configuration here. Pre-season combustion checks and flue inspections are what separate reliable winters from costly ones in Franklin. Duke Energy Ohio's Duke Energy OH Heat Pump Rebate currently offers up to $1,000 toward a qualifying system, which meaningfully shifts the cost-of-ownership math.
