Let’s dive deeper into the question, “Does car AC use gas?” below!

How Does Car AC Work? 

Before we fully answer the question, “Does AC burn car gas?” it’s a good idea to understand how air conditioning works in a vehicle. Regardless of manufacturer, AC works essentially the same way. Air conditioning runs on refrigerant, which is a high-pressure gas. The system requires the following components:

• Compressor — compress the refrigerant down into a fluid. This allows it to flow to the condenser. 
• Condenser — removes heat from the refrigerant and moves it to the expansion valve or orifice tube. 
• Expansion valve or orifice tube — converts the refrigerant back into a gaseous state, then sends it to the receiver/drier or accumulator. 
• Receiver/drier or accumulator — pulls the moisture from the refrigerant and sends it to the evaporator. 
• Evaporator — removes the heat from the air passing through its core, then sends it to the refrigerant. This results in the flow of cold air. 

Can Using Car AC Be Fuel-Efficient? 

Does air conditioning in the car use gas all the time? Is it ever smart to use the AC in your car? When traveling at highway speeds outside of Cadillac, it’s actually more efficient to use your air conditioner! Why? Because open windows create excess drag. With the added resistance, your engine has to work harder to create forward motion. So, if you’re cruising down the highway on a warm summer day, you can run the AC guilt-free!
