How does the technician show this? Does he connect the compressor to a gauge or other device? Paano ko malalaman na wala ngang discharge pressure?

I'm asking because my vehicle, 2006 Hyundai Starex GRX, had its first ever cleaning last March. At that time, the aircon shop replaced the evaporator coil (butas na) and the drier. Things were okay until last August, when I noticed a decline in the performance of the aircon. Brought it back to the same shop in Pangasinan. They told me that the freon level was still okay, but that the compressor needed to be replaced.

When the vehicle is not moving, the aircon hardly feels cool, but when the vehicle is moving, it gets a bit cooler, but still not as cool as before. I've checked the auxiliary fans, and they both work.

So, my question is: How can I tell if the compressor is really the problem?
