We are looking into purchasing a home with a Tempstar NUGM125EKA1 furnace. The home inspector said that this model of furnace is known to have problems with the heat exchanger cracking. If this is true, has the replacement exchanger been re-engineered to prevent this problem? Is there any way to tell if the previous owner had the exchanger upgraded already? I can't ask the previous owner because he is unavailable. What would an estimated heat exchanger replacement cost? Is this something that may happen or something that will happen? If hasnt happened yet does that mean this heat exchanger is a quot;goodquot; one and it wont happen? Thanks in advance.
You did not provide the SN# so here is my answer to you. If your unit falls within the range. . Heil and Tempstar Furnace Eyelet Failures Models NUGM, NTGM, NDGM, NCGM with date codes of L9421 through L9723. These furnaces were subject to premature heat exchanger failure and were thus the subject of a service bulletin due to eyelet failures. If you own one of these furnaces, we suggest that you speak to your heating contractor for possible repairs or replacement of the system. I would have the exchanger checked for cracks or holes where the exchanger is pinched together with rings. Its not worth replacing if you as me, you would be better off with a new furnace. I would also advise you to install a carbon monoxide detector. The had issues and to be honest I cant remember if the revised heat exchanger corrected this problem or not. The statement above are from an old svc record, so just based on that I would junk it if it has problems there were nothing but money pits
