my gas furnace was not heating very well. A contractor checked it out and cleaned the burner gas supply nozzle. my furnace is a Coleman installed in my mobile home. What temperature differential should I be getting between the return air to the furnace and the output air from the furnace. I am getting 74 degrees return and 85 degrees at the closest register. Is this normal?
