    bryant air handler

    we're working on 4 eight flat apt. buildings. Each apt. has an air handler that is piped for either hot or chilled water depending on season. So far two of the coils leak. Do you have a source for replacement coils? Bryant m/n 100-511D series A A-coils 15 1/2 W X 20 1/2 D X 10" H. Capacity approx. 16,000 btu cool 30,000 btu heat. Thanks

    Replacemant coils

    should not be hard to find.
    I would be more concerned about why they went bad in the first place. Is there anti-freeze in the system? Has it been tested? You need to find the cause of the failures before the rest of the system is damaged any further.

    failure

    These systems are 30 - 35 yrs old. No anti-freeze that I know of. The headers cracked at the steel end plates. I still need some help here!

    Ask \"WHY?\"

    True that, Tom!
    Sometimes we get caught up in finding the effect of the problem without delving deeper to find the actual cause. As I teach in my classes, as Tom can attest, I am I firm believer in continually asking the question "Why?". When you can no longer answer that question, you have most likely found the cause for the system failure.
    A simple example of this would be going on a "no heat" service call and finding the primary control has gone off on safety. Simply resetting the control is not solving the problem, just removing the effect. Asking yourself why the primary shut the system down will bring you that much closer to the actual cause of the problem.
