Full Answer

A combination furnace and air conditioner typically functions by constantly reading the thermostat temperature and applying either heating or cooling to reach the temperature set. When the ambient temperature is lower then the thermostat temperature, the furnace activates, drawing air through the unit and opening a valve that allows gas to flow through. The gas is then lighted by the furnace's lighter, with the resulting heat funneled through the device's heat exchange system where it heats the building, increasing the ambient temperature until it reaches the thermostat temperature.

When the ambient temperature is higher than the thermostat temperature, the air conditioner begins pumping warm air out of the space and circulates it back into the building as cold air using a refrigerant. The unit compresses the refrigerant, which heats it up, and then passes the heated refrigerant through a channel that dissipates the heat, causing a reaction that evaporates the liquid refrigerant, absorbing heat and cooling the room.

Employing a strict maintenance routine is the best way to guarantee excellent results from using a combination air conditioner and heating unit. Since it is a two-in-one system, mechanical failure typically makes both heating and cooling impossible.
