SOURCE: hums and freezes up????
The fan motor must have been stopping. If the fan stops, for sure the fins will freeze because there is no air flowing. common Fan motor problems defective bearing or bushing and starting condenser. If the bearing is defective, it will heat up and seize. Have the fan motor checked. The fact that the fins are freezing, means that there is enough freon and the compressor is working.

Replace the run capacitor. It is a silver cylindrical object located in the electical compartment of you outside unit. There is most likely three places on the top where different color wires are attached. One is marked F,or Fan. The center should be marked C, or Common, and the last should be marked Herm, with wiring to the compressor. Make sure you write down or label each wire you remove and it's correct location. They must be installed on the new part just like they were on the defective part. For you to know which dual run capacitor you need, the old one will have printed on the side either 370, or 440 v,as in volts. You must also need to know the microfarad rating and it is also printed on the side with the voltage rating. Since this is most likely a dual(runs fan and compressor) you should see two ratings abbreviated as mfd. Something like a 5mfd for the fan motor and perhaps a 35 mfd for the compressor. CAUTION !!! This device has line voltage and you must insure the power is off at the disconnect/ breaker BEFORE you begin the repair. Sounds complicated but really only takes a few minutes. The main thing is getting the right mfd and voltage ratings for the new part and keeping a record of where the wires were mounted on the old one, and putting them back the same place on the new part.

The squeaking noise is probably a bad or dry bearing in the fan motor, causing it to run slow or not at correct speed. Sometimes there are oilers on the motor that you can try to oil but the motor really needs to be replaced.

If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs
