What does an AC compressor do

I’ll now explain that an A/C compressor’s main role is to pressurize the refrigerant in your car’s air conditioning system, enabling it to absorb heat and cool the air inside the cabin.

Essentially, it’s the heart of the A/C system, circulating refrigerant through the system’s evaporator and condenser coils. Here’s how it works: the compressor draws in low-pressure refrigerant gas from the evaporator and compresses it.

This compression raises the refrigerant’s temperature and pressure. The heated, high-pressure gas then moves to the condenser where it releases its stored heat to the outside air.

Afterward, the refrigerant, now a cooler, high-pressure liquid, is ready to cycle back through the system, absorbing cabin heat and perpetuating the cooling process.

What happens when AC compressor goes out

When an A/C compressor fails, your car’s cooling system can’t circulate refrigerant, leading to a complete loss of air conditioning. This is more than just a comfort issue. The compressor is the heart of the system, and without it, the entire climate control is compromised.

You’ll first notice the air blowing from the vents is no longer chilled. Over time, the lack of pressure and circulation may cause other components to deteriorate.

Without a functioning compressor, the refrigerant can’t absorb heat from the car’s interior. There’s also a risk of refrigerant leaks, which can damage the environment and lead to costly repairs.
