Let’s see what is the truth! Is it necessary to turn off the air conditioner before parking?

Does turning off the A/C before turning off the engine really help protect the engine?

Car air conditioning is a system that cools the interior of the car, making your journey more comfortable. It is considered highly desirable in a hot city where everyone craves the cold air.

However, when talking about maintaining the service life of the car, many people often wonder whether turning off the air conditioner before turning off the engine will negatively affect anything. What is actually the right thing to do? Today, PTT Lubricants has the answer for you!

Some people believe that the air conditioner in the car should be turned off every time before turning off the engine. They think turning off the engine without turning off the A/C first will increase the work on the battery, causing it to run out quicker and may result in starting difficulty as the electricity in the battery starts to weaken. People also think that doing so can shorten the service life of the air compressor as well. 

Such belief is actually TRUE for all cars that do not have a delay system for turning on the air conditioner. When you start the engine, the starter will exert to start the engine and the air compressor will be driven simultaneously through a belt. Therefore, if the air conditioning system starts working as soon as the engine starts, it will put too many loads on the battery from having to handle both the engine and the cooling system. When having this many loads, if the electricity in the battery is low, it will take longer to start or you may not be able to start the car at all.

Then, turning off the A/C button before parking is still necessary? 

Because turning off the air conditioner before shutting off the engine is still necessary, turning off the A/C button 2-3 minutes before reaching the destination is still a good thing to do. When you turn off the A/C button, it will cut off the operation of the air compressor without shutting off the fan. With the fan still running, it can remove moisture from the evaporator coil of the air conditioning system and will reduce unwanted damp odors as well as the occurrence of mold, dust and bacteria inside the air vent.

Hope this information will help you understand more about how to properly take care of your cooling system. Lastly, don’t forget to regularly check the condition of the car, especially the air conditioning system. It is important to always check the condition of the air filter, refrigerant as well as look out for any leak so that the problems can be solved before it is too late! With care from PTT Lubricants
