How It Works
Furnace System Basics
The most common type of system pairs
an interior gas furnace with an exterior
air conditioner. Furnaces can also be
paired with a heat pump, which is then
called a dual-fuel system. Matching
your furnace with a compatible

air conditioner or heat pump
will generate optimum efficiency and
ideal system performance.

1. When it gets cold inside your home, your thermostat
automatically activates your gas furnace to compensate.
2. The burners ignite the gas and create warm air in the
heat exchanger.
3. The blower turns on and forces the warm air throughout
your home via ducts.
4. Warm air is circulated throughout your home until the
desired temperature is achieved.
