Is it harmful to leave the car running with the AC on overnight?
1 Answers
Leaving the car running with the AC on while parked can have negative effects. Here is a relevant introduction about the impacts of leaving the car running with the AC on while parked: Reasons: When the car is idling, the engine speed is relatively low. Running the AC can cause incomplete combustion of fuel in the engine, which may lead to carbon deposits in the cylinders and on the throttle valve. Additionally, leaving the engine running with the AC on increases fuel consumption. Disadvantages: When the engine is idling, due to incomplete combustion of fuel, the exhaust often contains a high concentration of carbon monoxide. The carbon monoxide emitted with the exhaust can accumulate around the vehicle and enter the interior through the AC system. Moreover, with the AC on and the windows closed, the air does not circulate. Over time, the concentration of carbon monoxide inside the car can become increasingly high, posing a risk to human health.
