    Actually I sent it in a week ago, then sent an email a few days later asking about it and then wed, I sent another...maybe I am doing something wrong. I have not heard back, can you check into this?

    You aren't pay the bills for those contractors.
    Not a fair analogy. It took that doctor 12 years of hard work to get to a point where he or she is qualified to make a diagnosis. For all the customer knows that tech who the customer is paying! to do this service just started doing this yesterday.

    Forgive my extreme ignorance here, but are those hairline cracks an actual problem? I guess where I'm going here is: if a Heat Exchanger is cracked, yet no combustion byproducts pass through it, then what is the issue? I'm not trying to be combative here... just trying to educate myself.

    On another note, estimator number two was just here. He said the 20-ish year old system probably doesn't have too much life left, regardless of the crack. (He wasn't a tech, and didn't feel qualified to look the crack himself...)

    Metal expands as it is heated up. The cracks then open up which can let carbon monoxide into the air stream and also can allow the flames to come out the front of the furnace....any crack can be dangerous, regardless the size.

    Yes they are a problem and need to be delt with before they split wide open. Just like when the Doc says your blood pressure is way too high,or the mechanic says your CV joint is bad. You don't wait to have a stroke or let the wheel all but fall off before dealing with it.

    I say that I can't see that it is cracked but my eyes are not the best and I refuse to say it is not cracked because of The legal liability. I would rather say it is cracked and be safe then say it is not and hurt someone. It is just the way I do business. I have not been put in that perdictament to many times. But when Ifind cracker I tell them to phone the gas company instead of another heating company, because the gas company does not sell furnaces.
    Do it right the first time.

    Andythedrew pull your head out of your ass! We also have to be schooled and take on going trainning and are ridiculed steady for what we do, If you think all doctors are perfect because they have done 12 years of hard work. I have been working as hard as any doctor I know and I have been doing this 23 years. I have thought about becoming a doctor but would go insane of only working 25 hours per week and on holidays every second month.

    Ps if you think HVAC guys are crooks, then maybe you should do something about it and become one. That is what I did!!!

    How can fumes go from the negative pressure in the hx to the positive pressure of the airstream?

    It won't always, but you asked how it could and the answer is because if the crack opens up when heated and the blower is blowing across the exchanger at a greater force and cfm than what the inducer motor is it can suck the gases out and into the air stream.

    And if it is a natural draft and has no inducer than it is ever easier for it to do and let's not forget about the fire hazard of flames coming out the front of the furnace due to cracks.
