company news about Car A/C System Flow

Just like blood vessels, your car's AC hoses carry refrigerant to keep you cool. Learn how they work and why a leak means no cold air!

Think of your car's air conditioning system like a human body. The AC hoses and lines are the blood vessels, constantly pumping the "lifeblood" – the refrigerant – to every part of the system.

Here’s what happens when you turn on your AC:

1. The Compressor is the "Heart": It starts the process by squeezing the refrigerant into a hot, high-pressure gas.

2. Travels Through High-Pressure Hoses: This gas flows through sturdy high-pressure lines to the condenser (in front of your radiator), where it loses heat and becomes a liquid.

3. Cools Down and Blows Cold Air: The liquid refrigerant then moves through an expansion valve into the evaporator (inside your dashboard). Here, it instantly cools down, absorbing your car's hot air and blowing out cold, refreshing air.

Throughout this entire cycle, AC hoses—both high-pressure and low-pressure—seal and transport the refrigerant. If any hose gets leaky or clogged, the refrigerant escapes, and your AC will simply stop blowing cold air.

The Bottom Line:
Without healthy, sealed AC hoses, your car’s air conditioner cannot cool your car.
