My fiance is back home, taking care of my house. She informed me that the furnace was blowing but, not warm air. I told her to check the pilot light, and she said it was out. She refused to follow the simple instructions (that I used twice in the 3 years I lived there, without incident) and relight the pilot light. So, my neighbors use an HVAC guy for all of their heating and cooling needs, and they referred him to my fiance. This afternoon, I received and email from her, post inspection, stating that I was in need of a new furnace, and that if it were to run it would kill anyone in the house within 3 hours, due to CO poisoning (though she wrote Co2 in her email)... It is an old Lennox furnace, from 1984, but the model escapes me at the moment. In any event, I am curious as to how the furnace that was inspected in late 2007 when I bought the house, has deteriorated to the point of emitting such high levels of CO over a period of four years. She told me that there was a smell in the basement, and was told that was the scent of CO (or Co2), both odorless, mixed with something - "He also said that's what that lingering smell was in the basement...it's not the co2, but the stuff it's mixed with."
Any guidance you can provide would be greatly appreciated. I know that I need to replace the furnace in the near future, but my gut instinct tells me that there are no immediate health concerns.
“The pilot light still didn't stay lit. Then, when it did the fire was huge...he said it had a lot of CO2 in it, but was hoping it would burn off. Well, it didn't and he tested the air and the CO2 levels were off the charts.”
