My furnace guy said the heat exchanger of a unit has cracks. I also saw it; but it looked like a crack on the a little bit rusted surface, but i did not see a hole or anything like that. The guy put CO detector at the flue and the CO level shot up at 200 ppm and came back down at 25-30 ppm which I think is normal because that is what the flue is for. He said that is too high, and he says he sees usually 5ppm or low level. Potentionally, it can leak into the main airstream. But there is no CO in the air stream into our house. And then, he said I need to replace the whole unit or the heat exchanger. Is what he said reliable?
