Keeping the interiors of our cars and trucks cool and comfortable has been possible since HVAC was pioneered around 70 years ago. On your GMC G25, this would not be possible without the A/C compressor. The air conditioning uses a refrigerant called R134a to fuel a thermal reaction that emits cold air, and the GMC G25 A/C compressor, as the name would suggest, compresses this refrigerant into a dense liquid. After that it goes to an expansion valve that turns it into a gas so it can flow through the evaporator. That cools it so it can emit cold air. Without the A/C compressor, your vents would only blow air that was the same as the ambient temperature of the environment.
