    Turn the breaker off to the AC. That might save it if the compressor isn't already ruined . You will need to call a tech out to find the problem.

    Get a thermometer and check. If it's set on 65 and reads 65 but you're too cold then that's not a thermostat problem. Same with too warm.

    Your refrigerant is under pressure at all times so it doesn't matter if the AC is running or not. If there's a leak it's always letting tiny amounts out.

    Sounds like you have a heat pump. With the thermostat set on x degrees the heat pump puts out warm air. Turn it up a degree or two above x and the auxiliary heat comes on. Perfectly normal.

    Try a tech from a Lennox dealer. Heat exchanger inspection should be step one with that furnace. If it's cracked there's no sense in going any further.

    The answer is no. Only properly primed and glued joints are approved. When I have run across this in the past none of the joints were primed and they all needed repaired.
