Did tech find and repair leak?If not it is very possible you are low on refrigerant again.The system s sealed and should never have to have refrigerant added.

He only added the freon, 5lbs of it, he mentioned about leaks but wasnt sure where to find it. Im just so frustrated my kids cannot sleep

What should I do
Expert:  airheatman replied 2 months ago.

I would call him back and have him check to see if the unit is low again and actually fix the leak not just waste refrigerant by dumping into a system he knows is leaking.If you have access to gauges I will guide you in checking charge.
