It could be due to cold temperatures, yes.
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.

Bad clutch on compressor, unplug the wires from the AC compressor, replace fuse if doesnt blow fuse its in compressor, if blows then gounded wire
Because it doesnt like you... Because it doesnt like you... Because it doesnt like you...
This is not a DIY job. It is illegal to release refrigerant into the atmosphere. Special equipment must be used to purge the system before removing and re-installing the compressor. The new compressor and system must then be charged correctly with refrigerant and oil. Take it to a professional.
the ac condensor on a 1998 Pontiac Bonneville is right in front of your radiator not hard to change at all.
shes probably scared because shes never done it before
the head doesnt effect the output pressure of a compressor package but the size of the piston and the amount of clearence and volume between the piston and head changes your output psi
If compressor is running 80-100% of time without recycling, it may still be low on freon. If freon pressure is good, may be expansion valve.
the asiest way to see if it is working is to start the car, turn on the a/c, watch your compressor. you should hear a click than the center of the compressor pully will start rotating, if that doesnt happen you could be low in gas in your system, you can always fill it just to check
