Why is my furnace blowing cold air? | DuctWorks Heating & Air Conditioning
If the furnace is blowing cold air after you have started the unit and let it run for several minutes, there is likely a problem with the unit, so it may need repair or service. Once the burners have shut off and the unit is in cool-down mode, there may be some cold air that is generated. This is not normally a problem.

We believe keeping you updated is important.
