went on a no heat call today for a unit that previous serviceman couldn't figure out. upon arrival i am greeted by this serviceman, and i use that term loosely, he tells me he has replaced the gas valve, pilot assymbly, ignition control, and roll out switch and unit still won't work. unit is a 13 year old carrier gas pack purchased used by owner. first thing i do is pull the top off of the unit and find every cell in heat exchanger has a hole in it. owner says he has already paid over $400 dollars to the hack trying to get unit to run. i tell him it's going to cost a lot more than that to get unit running, he says forget about it, he will do something different.
wonder how much he had to pay for the unit ?
