Does Car AC Use Gas?

Air Conditioning


Sometimes it can be uncomfortable driving around Denver in the heat of summer. Fortunately, your vehicle likely has an air conditioner system that you can utilize to cool your cabin. With that being said, we know some drivers like you like to sparingly use your AC system because you may have heard that it uses extra fuel.



So, does your car’s AC use gas? Yes, using your vehicle’s air conditioning system does use some extra fuel. However, there may be some instances where using AC can actually be more fuel-efficient on Brighton drives. Discover how your car’s AC works today with the service professionals at Transwest GMC!

When Is It More Fuel-Efficient To Use Your Car’s AC?

While we’ve answered, “Does car AC use gas?” you’ll notice that we mentioned sometimes using your vehicle’s AC system is the most fuel-efficient option. Many new vehicles have been designed to be as aerodynamic as possible. Rolling down your windows, especially when you’re driving at high speeds, can increase drag and air resistance on your vehicle.

That increased drag means that your vehicle has to work harder to maintain speeds as you drive around Thornton. As your vehicle works harder, you’ll end up using more fuel. In many cases, using AC when you drive on the highway and rolling down your windows at lower speeds can maximize your efficiency.

How Your Car’s AC System Works

The air conditioning system is similar in many vehicles. They often pull in hot air either from the cabin or the exterior of your vehicle and the AC system cools the air to keep you comfortable on your adventures. Learn how your car’s AC system works below:

  • Refrigerant: A high-pressure gas that is vital to your vehicle’s AC system.
  • Compressor: Compresses refrigerant and turns it into fluid so that it can flow through your AC system.
  • Condenser: Draws heat away from refrigerant and allows it to flow to the expansion valve or orifice tube.
  • Expansion Valve/Orifice Tube: Allows the refrigerant to turn back to a gas and pushes it to the receiver or accumulator.
  • Receiver/Accumulator: Removes moisture from the refrigerant so the air blowing into your cabin is not humid. The receiver or accumulator also pushes the refrigerant to the evaporator.
  • Evaporator: Removes additional heat as air passes through it, allowing for cold air to enter your vehicle’s cabin.
