We may take this for granted, but it wasn't until the 1950s that vehicles were equipped with reliable air conditioning. On your GMC Sierra 1500 HD Classic, the main component of this system is the A/C compressor. The lifeblood of the air conditioning system is a refrigerant called R134a. The refrigerant emits cold air after a simple thermal reaction, and the GMC Sierra 1500 HD Classic 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. If your car or truck did not have a functioning A/C compressor, you would not be able to cool your vehicle on hot days.
