The furnace is a major part of a split or hybrid system. The furnace creates warm air to heat the home.
The furnace can also work in conjunction with a condenser or heat pump to circulate cool air throughout the home.
The furnace is comprised of a blower to circulate air, a gas valve, and a heat exchanger to heat the air.
If combined with an air conditioner or heat pump, a coil is attached to the furnace.
According to the American Council for an Energy-Efficient Economy (ACEEE), “Reducing your heating energy use is the single more effective way to save money and reduce your home’s contribution to global environmental problems.
Recent technology advances have given us two and three-stage furnaces using variable-speed blowers, which can improve comfort within the home and further reduce energy consumption.
