    My outside unit is coming on by itself, when I have the thermostat on off
    I recently had a contactor put on and now it is coming on when my thermostat is set on off. What might be the problem?

    Does the fan inside also come on or just the ac unit?

    Sounds like a t-stat problem then. Is it a programmable stat? Digital stat? Or old murcury?

    Will it also go off by its self? Or once it comes on, it stays on? When it comes on does it say cooling is on?
