How to get the best from a car’s AC
▪ Don’t bother to pre-cool. Air-conditioning works far better when a vehicle is in motion than when it’s still, because “the faster the engine turns, the faster the air compressor runs.” So jump in, start driving, crank up the fans, and open just the rear windows for 10 to 20 seconds. There’s no better way to vent out hot air.
▪ Dial it down. If you select any temperature above the AC’s coldest setting, the system has to warm air that it has already cooled. If you’re chilly, just lower the fan speed.
▪ Avoid recirculating. When you have passengers in the back seat, don’t use recirculation mode. It recirculates only the air up front, letting the air in back grow hot and stale.
▪ Turn off stop/start. The automatic stop/ start systems common in new cars save fuel, but they shut down both the engine and air compressor at stops, causing the cabin to heat up quickly.
