How Does The Car A/C System Work?

How Does The Car A/C System Work? | Taylormade Automotive

As a skilled team of mechanics, a thorough comprehension of your vehicle's air conditioning (A/C) system can make all the difference in creating a pleasurable driving experience, even on the hottest of days. Let us share a breakdown of the A/C system to ensure your driving journey is always a comfortable one.


Think of this as the heart of your A/C system. It's what keeps the refrigerant moving. The compressor draws in refrigerant gas, compresses (hence the name), and sends it out as a high-pressure, high-temperature gas to the condenser.


Located at the front of your car, often next to the radiator, this is where the magic of heat exchange happens. The condenser cools the refrigerant, turning it from a hot gas to a cooler liquid. It's crucial for the efficiency of the system, as it gets rid of the heat that was inside your car.

Expansion Valve or Orifice Tube

Here's where we control the flow. This part reduces the pressure of the refrigerant, allowing it to expand and turn into a low-temperature gas before it enters the evaporator.


Located inside your car's dashboard, the evaporator takes in the cool, low-pressure refrigerant gas. As air from the cabin passes over the evaporator, it gets cooled and is then circulated back into the cabin. This part is also responsible for dehumidifying the air.


The lifeblood of your A/C system. It's specially designed to change states (from liquid to gas and back) efficiently, absorbing and releasing heat in the process.

Receiver-Dryer or Accumulator

These components keep the refrigerant clean and dry. Moisture in the system can cause havoc, leading to corrosion and ice formation, which can block the flow of refrigerant.

Maintaining Your A/C System

Proper maintenance is key as with any other component. Check for leaks, ensure the refrigerant is at the correct level, and replace filters as needed. A well-maintained system not only keeps you cool but also extends the life of the components.

Frequently Asked Questions & Answers

How often should the A/C system be serviced?

As a rule of thumb, get your A/C checked annually. This helps catch issues early and maintains optimal performance.

What are the signs of a failing A/C compressor?

Listen for unusual noises, note if the air isn't as cool as it used to be, or if the A/C is not consistent. These can indicate compressor issues.

Can I run my A/C in the winter?

Yes, running your A/C in winter is actually good for the system. It keeps the parts lubricated and prevents seals from drying out.
