I have a colman gas furnace dgaa070bdta and it has a fresh air switch on it.What is this for?

To bring in fresh air to mix with home return air. Some also have an attic ventilation motor with the system.



Thanks for inquiring,
Robert

Do I keep the fresh air switch on in both winter and summer ? I do have cental air.

Thanks

Yes, it stays on year round and depending on model, runs at designated times as designed.


Thanks,
Robert
