My heating ducts in the ceiling are blowing cold air. The lower ducts are fine. Was looking for advice on how to access the connection point of the duct that feeds the ceiling. I believe it may have come disconnected. Any help or advice would be appreciated. Thanks
The round ceiling vents in Crusader are AC not heat
The floor vents are for heat only - the two rectangle vents in the ceiling on each side are the cold air returns for the AC system - those are why it is a much more quiet setup
You should not have any air from ceiling vents if running furnace - make sure your fan is set to Auto
