If you’re replacing your HVAC system and shopping around for efficient options, you might consider installing a heat pump. Heat pumps run on electricity to heat and cool your home, and are well known for their efficient, clean operation.

How Heat Pumps Work

There are two basic types of heat pumps: air source, the most common, and geothermal. Air source heat pumps pump refrigerant from an outdoor unit indoors and back again. In heating mode, the refrigerant gathers heat from the outdoor air and is pumped indoors to the air handler, which distributes the heat through the ducts. The cooling refrigerant is then sent outdoors to absorb more heat. In the summer, the process is reversed, with refrigerant absorbing heat from the home and exhausting it outdoors, much the way a traditional air conditioner does.

Heat Pump Efficiency

Air source heat pumps work best in warmer climates, where outdoor temperatures don’t regularly fall below freezing. When the outdoor temperature dips to near freezing, the unit defaults to an auxiliary source of heating, such as electric coils (which are inefficient to run for long periods) or a gas furnace (a more efficient option).

When systems are properly installed, heat pumps provide as much as three times more heat energy than the energy they consume. Since the heat pump is moving heat rather than converting it from fuel, it works much more efficiently.
