EarthWise® Hybrid Dual Fuel Packaged Systems

A heat pump uses the outside air to efficiently heat your home in the winter and cool it in the summer. Unlike a furnace, a heat pump doesn’t burn fuel to make heat. It simply uses electricity to move heat from one place to another, making it a greener, more energy efficient solution.

As part of a central heating and cooling system, a furnace converts fuel into heat, then uses a blower to circulate warm air throughout your house. In summer, the furnace works with your heat pump or air conditioner to draw in warm air from your house and recirculate the newly cooled air. The main components to a natural gas furnace include burners, a heat exchanger, blower and controls.

SEER stands for seasonal energy efficiency ratio. This industry rating measures the averaged annual energy efficiency of your system operating over the entire cooling season. A higher SEER means your cooling system is more energy efficient. You can learn more about SEER here.

AFUE stands for annual fuel utilization efficiency. This industry rating measures the averaged annual efficiency of a furnace. A higher AFUE means your heating system is more energy efficient. You can learn more about AFUE here.
