Heat Pump vs Gas: COP, Balance Points & the Switchover Math
A heat pump COP of 3.0 means 3 units of heat per unit of electricity -- 300% efficient (it moves heat, not makes it). A gas furnace at 95% AFUE makes 0.95 units per unit of gas. The operating-cost crossover: heat pump wins when (electricity price / COP) < (gas price / 0.95) per unit of heat. At $0.20/kWh electricity, $1.50/therm gas, COP 3.0: heat pump $0.067/unit vs gas $0.053/unit -- gas wins. At $0.15/kWh: heat pump $0.05 -- heat pump wins. Local rates decide everything.
COP collapses in cold: a unit rated COP 3.5 at 47F drops to 2.0-2.5 at 17F, ~1.5-2.0 at 0F. The balance point: the outdoor temperature where heat pump operating cost equals gas -- below it, switch to gas (dual-fuel systems do this automatically). Cold-climate heat pumps (Mitsubishi Hyper-Heat, etc.) hold COP 2.0+ down to -10F, pushing balance points to -5F or lower -- making full electrification viable even in Minnesota. Sizing: Manual J load calc, not rules of thumb; oversized short-cycles, undersized runs on expensive backup strips.
The decision framework: dual-fuel (heat pump + gas backup) is the safe optimum in mixed climates -- heat pump handles 80-90% of hours, gas covers extremes. Full electric with cold-climate pump works where winter design temps stay above -10F. The calculator takes your rates, climate data, and equipment specs into annual operating cost per system and the balance-point temperature -- because the answer is always local.
Refrigerant transition: R-410A is being phased down (AIM Act) in favor of R-32/R-454B -- lower global warming potential, mildly flammable (A2L) requiring updated handling. New equipment uses the new refrigerants; servicing old R-410A systems gets pricier yearly. If buying now, confirm the refrigerant -- it affects 15-year serviceability.
