Five years ago the advice was simple: gas furnace for cold climates, heat pump for mild ones. Variable-capacity cold-climate heat pumps have made that advice obsolete for most of our service area.
The deciding factors are your electric rate versus gas rate, the quality of your ductwork, and whether you already need to replace the air conditioner. If your AC is dying and your furnace is healthy, a dual-fuel setup often beats either extreme.
What we measure before recommending anything: design heating load, duct static pressure, existing electrical capacity, and your actual thermostat behavior over a season. Equipment that is oversized for a leaky duct system underperforms no matter what the label promises.
The honest summary: if your ducts are sound and your electric rate is average, a modern inverter heat pump will cost less to run than an 80% furnace and give you cooling in the same package. If your home has high infiltration and cheap natural gas, dual-fuel is still the smarter buy.
