    I got a no heat call about a week ago and it was an easy one. i guess it was easy. i did find the original problem but they had another issue that i had to tell them. Its a good start to the heating season. Its an old carrier rtu. I ended up putting in a new heat exchanger.

    found my first cracked heat exchanger of the season today(and my first as a tech). It was on a Trane single stage 90 that was 12 y/o. heard a rumbling sound when it first started up, took cover off the burner box and then sounded normal, flames looked good. About 2 minutes in to it running i see the front plate of one of the cells catching fire, i shut off the furnace and see the plate is all cracked and burnt up, further noticing signs of roll out all over the burner box. I then stuck my inspection camera down the cell to find a stress crack. Called the office to inform them, had a field supervisor come out to the call to verify it and to make it as easier (if possible) to break the news to the homeowner we then took the burner compartment apart and looked down the cell and touched it with a brazing rod, only find that crack was more than just a stress crack. I've never had issues with primary heat exchanger on a Trane or many 90% furnaces for that matter.

    we have been doing heat checks for about a month here started when it was still 90 plus outside. have yet to have our first heat call that wasn't due to them having the a/c running when i arrived. those heat exchangers are nothing in our humid climate i find heat exchangers 1/2 the tube is rusted through, i will take some pictures of the next really bad one i find.

    if this winter is anything like the last we will have very very few calls. our maintenance customers started to ask me if we had anything else to do last winter, we got very few summer calls from them there equipment was in fantastic shape.

    I usually find with older folks who try to damper off rooms I get cracked heat exchangers, and people who can't seem to change their filters more than once a decade. This usually gives me a clue to look a bit further. ...anyway, finally cold here in Texas.
