Keep Cool in the Mountains: AC Use While Driving Explained

The debate over whether or not to turn off your air conditioner (AC) when driving in the mountains is a common one among drivers. Some believe that turning off the AC can improve engine performance, especially on winding, uphill roads. But is this myth or fact?

According to Gunawan, owner of Premium 99 AC in Depok, the decision to turn off your AC in mountainous areas depends on your car's condition.

Modern Engines and AC Use

“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 says. “Modern engines are designed to balance power use with fuel efficiency, even with the AC running.”

Older Cars and Engine Load

However, if your car has a smaller engine or is older, turning off the AC might be beneficial.

“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.

Prioritize Comfort and Safety

It's important to remember that turning off the AC isn't always the best solution. Overheating in the cabin can lead to driver fatigue and loss of concentration, compromising safety.

Don't sacrifice comfort and safety to save a little engine power.

Ultimately, the Choice is Yours

The decision of whether or not to turn off the AC ultimately depends on your car's condition and your personal preferences. If you're unsure, it's always best to err on the side of caution and keep the AC running.
