- Don’t Precool. Your car air conditioning works much better when you’re actually driving because the faster the engine turns, the faster the AC compressor runs, which lets the system cool more effectively.
- Go Low. Setting to the lowest temp and adjusting the fan makes the car air conditioning more efficient, will dry out the air less, and can actually save some fuel.
- Don't Recirculate. If you have passengers in the back seat, consider turning off the recirculation mode. This takes air from the front of the cabin and pulls it back through the system, so even though everyone up front stays cool, the air in the back can get stale and hot.
- Turn Off Stop/Start. If you have a newer car that has an auto start/stop system, consider turning it off. This feature saves fuel, but for many cars it can keep the car’s air conditioning compressor from running when it shuts the engine off.

Most experts agree that choosing the lowest temperature for your air conditioner is more efficient for the car’s cooling system and saves fuel. Why?
