A heat pump provides a single source for year round temperature control.
During the warmer weather, a heat pumps acts very much like a conventional air conditioner.
It works by pulling heat from inside the home and pumping it outside. In the colder months, the process reverses, and the system extracts heat from the outdoor air and brings it inside the home. Even when the temperature outside feel chilly, the air still contains ambient heat. The heat pumps uses this heat, pulling it from the outdoor air and warming the home. This type of heating is extremely efficient and produces two to three times more heat than the energy it requires. Plus, the heat pump runs on electricity. It doesn’t burn fossil fuel to create heat, avoiding combustion byproducts. It doesn’t produce any carbon monoxide, carbon dioxide, formaldehyde or greenhouse gases. An electric heat pump provides an environmentally friendly option for both heating and cooling. The drawback of a heat pump is that it isn’t effective once the outdoor temperature drops below freezing. At that point, there’s not enough heat in the outside air to meet the demand of the thermostat setting. For areas with severe cold weather, it’s necessary to partner the heat pump with another type of heater. The heat pump can be used as an add-on option with an existing gas furnace. A dual-fuel system shares the heating demands, but the heat pump and furnace never operate at the same time. Each one works to provide the most cost-effective means of comfort. The heat pump supplies cooling and handles heating until the temperature dips below freezing. When it can no longer operate efficiently or effectively, the gas furnace takes over until the temperature rises up again.
