What happens when Furnace Fan is running all the time?
Although the air temperature will be similar to the space temperature, your house will feel cold. Your furnace filter will clog up quicker (even though that means it’s working), but you will have to adjust your filter more frequently. Your other option is to set your fan to AUTO, which means the fan runs when directed to by the unit.

Can a Furnace Fan be set to auto?
A typical thermostat will only have two settings for the fan, ON, or AUTO. In the ON position, the fan will run continuously. In the AUTO position, control of the fan is handled by the furnace instead of the thermostat. Since your fan does not run continuously, I’ll assume you have the fan control on the thermostat set to AUTO.

If the air filters are not dirty and the ductwork not clogged, check also the blower fan itself for dirt or debris: a small amount of dirt on a blower fan – the squirrell cage type – can dramatically cut the air flow rate of the fan. if none of those problems are present I’d try setting up the ON time to 5-6 minutes.
