    Why would you need to clean the middle coil???

    This is on all 40 + units.. I'll be working for the next 10 years.....

    Why I HATE acid cleaners. the middle coil had 30 years of junk on it, it acted like a sponge holding the acid cleaner....

    The middle coil was in worst shape then the outside/inside coil...................

    Lots of very very small leaks...........

    if you don't COMPLETELY RINSE any cleaner away, it will end up bad....eventually.

    you shouldn't see ANY soapy bubbles coming off a coil when done rinsing.

    Its not the cleaner in my opinion. Its the guy who did not know what he was doing cleaning the coil.. I have been behind guys from the same company a week after a maintenance.

    Running 350+ head pressure was the easy give away..
    Gotta have the right tool for the job!

    Where is all the stuff MADE IN THE USA?

    Like Pascone10,
    If you don't know..... On the job training is great, if the teacher knows...

    I just found a Service manual from 1984 for the carriers 38AE, it shows how to clean the coils. I guess the other HVAC tech's from the past couldn't read or care...

    71CHOPS,
    You still have to split the coils, even if it's two coils. Check out the photo's of the coil I sent in, it's three coils.

    If you live in the Mid West, splitting coils must be done every Spring / Summer due to cotton woods floating around. Tranes have to be the worst for me to clean once they get up to 15 tons and above as you may need an extra set of hands cleaning the coils right.
    I am not a believer in chems on coils, only if grease on coils is part of the issue.
