Sounds like you have dirty condenser coil or bad condenser motor if it runs fine in the night

It is likely the AC units control panel has failed.

Compressor not running or freon has leaked out of unit.

Well, letting things sit that long isn't good for them. It probably lost it's charge of freon.No way to fix that.

Is this a code for us to come over cause electric furnaces dont use a pilot light ha! Ha! (they uses electric heat strips for heat .....but if you want to give away money..........)

either bad fan motor or dirty condenser coils need cleaned..possible obstrution with fan motor keeping it from turning.

If this is a ducted unit, check the thermostat. It has a fuse for protection that may have blown. If the fuse is fine and you have power to the upper units control box, check for 120V incoming power at the control box and also check for incoming 12V on the Yellow and GH wires when tstat is set to high cool.

Hope this helps.

If the large line returning to the compressor is frosting you don't have enough air circulation. Check air filters on inside unit.
