Hey all, I have had this problem off and on this winter. My heater will run for long periods of time. Ever so often (usually when I come home from work after it's been on all day) it will smell funny, like some kind of gas (not sure) and the Temperature would have dropped like 10 degrees. The heater would have been running this entire time, but sounds different than usual. I sometimes turn it off for like an hour, and works fine for about 3 weeks. I have called the heating company and they came out, charged me $75, did an inspection and told me they could not find anything. Can someone help me out? I really don't want to pay them again for noting, but I am afraid of the fumes, as they may be harmful. Thanks in advance.
The fumes are harmful, any fumes through your heat ducts would indicate a hole in the heat exchanger,I may be wrong but it sounds like its time for a new furnace esp if yours is older. t
