Try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If you have any other Air Conditioning Repair Questions don't be afraid to let us know.

See if you can reposition the thermister on the facing of the evaporator coils. That could be it or the thermister might be bad. They don't use copper/mercury sensing bulbs these days. They use these cheap thermisters.

Does not sound right to me.My guess after doing what every he was doing he probably installed a start capacitor or repaired a burnt wrie, got the compressor running and charged for a lot of guess work. Just guessing.

Check the controls, this unit most likely a reverse cycle air conditioner. It can be set to cooling or to heating. The conpressor is reversed to heat or running normally to cool.
If it is not then the compressor is not working and it is just blowing room temperature air.

If the drain is clogged or the ac is not slightly tilted towards the outside, the condensed water will leak inside instead of outside where it belongs.

Either your coil is dirty or filter is dirty. Worst case your low on freon which would make a coil freeze.But freon doesn't evaporate if your low there must be a slow leak.

Check to see if there's power to the reversing valve, if there is, try tapping it slightly with something kind of soft. You should give the reversing valve solenoid a continuity check with an ohmmeter to see if it's open or shorted.

If this is a window or wall mounted single piece unit, open it and check for a loose compressor or fan mount.
