    A/C always running cold
    We have 3 a/c units and 4 thermostats. All are set to cool at 76. Our media room has its own thermostat which we have set to off, but it is about 68 degrees in there! Wanted to see if anyone had any advice before I called our home warranty :confused:

    They are all electric.

    I don't really know how/why there are 4 stats. Two down stair- one in the master and one for the rest of the bottom floor. 2 up- one for the media, the other for the playroom and 3 beds.

    If you only have 3 units then one must be controlling a damper. Sometimes these dampers are power closed so try turning the one on in the media room and see if you still get air out of the registars
