    HVAC folks need help

    Came home tonight to no AC. Have a heat pump/AC unit outside, it is running but fans in basement unit are not turning on. Went downstairs and found the refridgerant line from the outside unit to basement unit is frozen solid. It is an old unit, over 20 years old.

    As you can probably guess I am clueless on these things. Currently have it turned off but any ideas what it might be? Anything I can do?

    If your indoor blower fan is not running that's why its frozen. Could be a fan cap, fan motor, fan relay, or control board.

    Make sure your indoor blower is operating, then see if the filter is dirty. Turn outdoor unit off and switch indoor blower to "on" and let the coil thaw out. Then check the refrigerant charge. Good luck, too damn hot for no ac!

    Step one, make sure the fan works. Let us know if you want more from the peanut gallery after you check it out.

    "Unthaw"? Might be better if you just let it thaw.

    I think Chadsc is the only one that read and comprehended the complete post, "fans in basement are not coming on."! And he is dead on.

    This, it will freeze them up in no time. Shut it down and make a call.
    You might be able to shut the breaker for the AC for a few hours with the fan running and let it thaw. But it will freeze up again rather quickly

    Just saw that. Mine was leaking at the valve stem. Hooked the hoses and pumped it high pressure and sprayed everything. Never lost pressure for 1/2 an hour. I was thinking WTH. Took the hose off and,, there we go, simple fix

    Mine too. If you have a "hot water heater" then your water supplier must be tapping into a hot spring

    Yep, from previous posts I believe he is an a/c tech. I agree with him and I'm an a/c guy as well, for 43 long, long years!
