tempstar gas furnace

I have a tempstar gas furance. The only issue I have with it is that when it starts forcing heat thru the ducts the air is on the cool side. it does heat up but it tends to take longer than it should to heat. Someone was telling me that the thermo coupler is going bad. Does this sound correct to anyone with the same issue? Thanks for your time.

The thermocouple is used to verify that a pilot light is burning before the main gas valve opens. That is not your problem.

It may be that the blower is coming on early, but you always have the room temp air pushed out before you feel the heated air.

No Heat

You need to take the cover off the burner compartment, stand back a little and start the furnace and see what is happening in there if all the burners are firing and they look mostly blue with a little yellow your furnace is firing mostly ok. You may be getting some return air leakage introducing cool air to your system. If the furnace is not firing allright you need to call for service.
