temp. but he keeps running there a problem or solution?

The thermostat is probably shot. It is a fairly common problem with the window AC units, especially if you've had for a few seasons. If the freezing of coils and shots do more colder, it is probably time for a new one.

Did they also check the thermostat? A lot of times if they go bad air does not stop.

You can check that the temperature is regulated. Most of the COs cool to about 20 degrees outside temperature. If the servants do this correctly then think, if 90 F outside, it's not going to cool to 70 F. It may be a + / -, but I Figure 20 Degree down a good point. So if you have the temperature set at 60 F and 90 F outside, it can keep blowing full force trying to reach this temperature.
One last thing. IF the CA off for a period of time, things in the heat of the house to whatever the temperature. Diapers, walls etc. As the CA trying to cool these off heat, until they are cooled. Thus, taken into account. Turn the thermostat to cut CA. Later, when he turns it down a few degrees. Finally, you return to normal. This will work better at night when cool outside.
Once everything cooled down should cycle on and off, otherwise the above answers are accurate and that you may need a new thermostat. SI, the service person did their job correctly.

sounds like a vacuum line is off
