Tell me about how old the furnace is please and if you have air conditioning attached or not.
If the house is being kept warm we know that the furnace is working, it may be that the blower is simply not shutting down after the heat cycle is complete.
Does that sound like what might be going on?
Tell me a lot about your technical skill sets so that I will know the best way to approach this with you please.
