How to Switch Furnace from Winter to Summer Setting

Kitchen SinkWhen you use a forced air furnace for summer cooling, you should open the high returns. This allows the furnace to take warmer air from the top of the room back to the air conditioning cooling coil in the furnace. In the winter, open the low returns to collect cold air at the floor.

For a two-story home, you may also need to adjust the supply air for winter and summer.  In the winter, warm air rises to the second floor, so less heating is required there. In the summer, warm air still rises, and a hot attic adds even more heat, so you need greater cooling (air flow) to the second floor than to the first floor.
Heating ducts vary. Some systems have levers indicating the direction of the damper. Some rectangular ducts have dampers and levers. To adjust air flow for summer cooling, start by fully opening all second-floor dampers. Next, partially close dampers to first floor rooms that are getting lots of cold air. You will find that closing the damper to 50% or turning the shaft to 45 degrees will only partially slow the air flow. Often, even if you fully close the damper, there will still be air flow because the dampers fit very loosely in the ducts.
