Modern car owners no longer need to worry about turning off their AC before killing the engine, according to a leading auto repairman. In a recent video, the mechanic debunked the widely believed myth, explaining that older vehicles, particularly those predating the 1990s, may have required such a practice due to outdated electronics. However, with the advent of computer-controlled HVAC and engine management systems in cars from the 1990s onwards, this precaution is no longer necessary.
The mechanic emphasized that newer cars are designed to automatically disengage the AC compressor before the engine comes to a full stop, preventing any potential damage. In fact, some modern vehicles are equipped with variable compressors that eliminate the need for a clutch altogether, further dispelling the long-held myth. Instead of manually turning off the AC, drivers are encouraged to make use of the auto AC mode in their vehicles, which includes built-in logic for post-drive drying cycles to prevent moisture buildup and potential issues like odors or leaks over time.
