The service person shouldn't be recharging the refrigerant unless they have found and repaired a leak. Or do you mean an antifreeze solution that is pumped round the system? If so the service person should have checked the cooling system was working before adding coolant.

I'm not familiar with your unit, but sounds like condenser problems. Check for a dirty coil on the backside or underneath the unit. Also, if it has a fan for that coil, make sure it's running when the compressor is running and that the blades are clean. Other than that, it could have developed a refrigerant leak.
