A heat pump paired with a gas furnace. The heat pump handles mild weather efficiently and the furnace takes over in deep Minnesota cold — the best of both.
Why this matters for your home
A dual-fuel (or hybrid) system pairs an electric heat pump with a gas furnace and switches between them automatically based on outdoor temperature. The heat pump handles mild and shoulder-season days at high efficiency, and the furnace takes over when it gets cold enough that gas heat is cheaper and stronger.
For Minnesota, this combination captures heat-pump savings most of the year without giving up the dependable, fast heat of gas on the coldest nights. The crossover temperature is adjustable, and we tune it to local energy prices so the system always runs on the cheaper fuel for the conditions.
