Understanding the Basics of an AC Compressor – AC Compressor From Junkyard
You know that sweet, cool breeze on a hot summer’s day? That’s all thanks to your car’s AC compressor. The AC compressor is the heart of your vehicle’s air conditioning system, circulating the refrigerant throughout the system. Without it, you’re left with a car interior hotter than a desert.
What is an AC Compressor? – AC Compressor From Junkyard
Picture the AC compressor as the hard-working mailman of your car’s AC system. Its main job? Delivering refrigerant where it needs to go. In the process, it compresses the refrigerant from a low to a high-pressure state, enabling it to absorb and remove heat from your car’s interior.
Function of an AC Compressor
In essence, an AC compressor is a pump. It sucks in the refrigerant gas from the evaporator, pressurizes it, and then sends it off to the condenser. It’s a continuous cycle that keeps your vehicle cool and comfy.

No AC compressor, no cool air. It’s as simple as that. It’s the critical piece that sets the whole AC system in motion. Without it, those sweltering summer drives become unbearable real quick.
