Learn why and how AC uses gas and then keep your vehicle at its best with our service experts at Rick Hendrick Chevrolet Buick GMC Richmond today!

How Car AC Works

It doesn’t matter what kind of vehicle brand or model you sport on Glen Allen roads, your air conditioning system works in the same way by using high-pressure gas called refrigerant to deliver cooler air to your cabin. Here is what your vehicle’s air conditioning system is made up of below:

• Compressor – Compresses the refrigerant into a fluid, allowing it to flow freely to the condenser.
• Condenser – Lowers the temperature of the refrigerant and sends it to the expansion valve/orifice tube.
• Expansion Valve/Orifice Tube – Reverts the refrigerant to its original gaseous state and delivers it to the receiver/drier (also known as the accumulator).
• Accumulator – Lowers the moisture content of the refrigerant and delivers it to the evaporator.
• Evaporator – Extracts heat from the air that passes through its core, and transfers the heat to the refrigerant. As a result, cooled air begins to flow from the evaporator.

Can Using Car AC Be Fuel-Efficient?

While this might seem counterintuitive, some cases enable you to get more fuel efficiency when you use your AC as opposed to rolling down the windows! According to the EPA, when you roll your windows down at highway speeds this increases aerodynamic drag and makes your engine work harder to keep you moving. So, on the highway, it’s actually better to turn on your AC.

Other Ways to Improve Fuel Economy

On the other hand, you can also slightly improve your fuel efficiency when using your AC by following these tips:

• Brake gradually
• Use high-quality engine oil
• Don’t pack too many heavy items
• Ensure proper tire alignment and inflation
• Avoid idling for longer than 30 seconds
• Use a sunshade when parked in direct sun
• Reduce speed and drive in a higher gear
