Does idling with the air conditioning on harm the car?
2 Answers
It can cause some damage. Idling with the air conditioning on without turning off the engine will increase carbon buildup in the engine. Below is more information about car air conditioning: Introduction: The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. It provides a comfortable environment for passengers, reducing travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. Components: Generally includes a refrigeration unit, heating unit, and ventilation system. This combined system makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.
As an old-timer who's been driving for over 20 years, I think idling with AC on requires caution. If you keep the AC running while parked for extended periods, the engine has to idle to power it, which causes fuel consumption to skyrocket. It's fine occasionally, but frequent idling can lead to carbon buildup inside the engine, increased wear, and even affect spark plugs and the exhaust system. Especially during summer in garages - if it's an enclosed space, carbon monoxide from exhaust can accumulate rapidly, posing extreme danger. My advice is to crack windows for ventilation when necessary, or schedule regular maintenance checks on engine condition. Bottom line: for your vehicle's longevity and safety, don't make idling with AC a habit - shut it off after 30 minutes max.
