Yes, Mini Splits Heat in Winter—Even in Missouri
Thanks to inverter technology and improved refrigerants like R32, many mini split systems provide strong heating power even in outdoor temps as low as -13°F.
Heat Pump vs. Traditional Furnace
Mini splits operate differently than gas furnaces or baseboard heat:
Furnace: Burns fuel to create heat
Mini Split Heat Pump: Transfers heat from the outside air—even cold air—into your home
Because they transfer heat instead of generating it, they’re far more energy-efficient. In fact, mini splits can deliver up to 300% efficiency, meaning they produce three units of heat for every unit of electricity they consume (source: ENERGY STAR).
