Should You Turn Off Your AC When Driving Up Mountains?

Navigating winding, uphill mountain roads can leave drivers wondering about the necessity of using air conditioning. A common belief suggests turning off the AC can improve engine performance, but is this truly necessary?

AC Use in Mountainous Areas: A Matter of Car Condition

According to Gunawan, owner of Premium 99 AC in Depok, the decision to use AC in mountainous areas hinges on the condition of your vehicle.

"If your car is in good shape and the engine isn't working too hard, there's no need to turn off the AC," he states. "Modern engines are designed to balance power use with fuel efficiency, even with the AC running."

Turning Off AC for Older or Smaller Engines

However, if your car boasts a smaller engine or is older, turning off the AC might prove beneficial in reducing the engine's workload, particularly when tackling steep inclines.

"In cars with small engines, turning off the AC can slightly lighten the load, allowing the engine to focus more on the vehicle's performance while climbing," Gunawan explains.

Comfort and Safety: Don't Sacrifice Them for Engine Power

It's crucial to remember that switching off the AC isn't always the optimal solution. Don't compromise comfort and safety to conserve a little engine power. Overheating within the cabin can lead to driver fatigue and impaired concentration.
