Many drivers often have to park their cars for a long time to wait for customers or rest and still maintain air conditioning operation. According to a technician at Ninety Eight Auto Motorcycle Repair, Maintenance and Care Center (Cat Lai ward, Ho Chi Minh City), using air conditioning when the car is still there does not cause damage to the air conditioning system, as long as the engine still operates and operates stably.
When the engine is working, the air conditioner compressor is still driven normally, so the cooling system continues to cool as when the car moves. Therefore, parking for one to two hours and turning on the air conditioner is not a direct cause of damage to the cooling system or related parts.
However, to reduce the load on the system, users should not set the temperature too low for a long time when not necessary. Maintaining a reasonable temperature level helps reduce the load on the air conditioning system, especially the compressor, while saving fuel.
An important note is not to turn off the engine but still let the air conditioner and electrical appliances operate for a long time. Because this will cause all the electricity to be taken from the battery, causing the battery to quickly run out of power and may not have enough energy to start the car later.
For the air conditioning system to operate sustainably, car owners should clean the air conditioning system, check the air conditioning filter, check the amount of refrigerant and maintain it according to the manufacturer's recommendations.
If a lack of refrigerant is detected, it is necessary to supplement with the correct type and amount according to technical specifications, instead of just recharging gas periodically. Recharging gas when the system still has enough refrigerant does not bring benefits, and may even affect the cooling effect if overloaded.
In addition, some car owners experience the phenomenon of the air conditioner on the passenger seat but the driver's seat cools poorly when the car is unloaded, while the car moves normally cold. According to Ninety Eight Auto, this may be a sign that the system lacks cold environment, causing the cooling ability to decrease when the rotation speed of the compressor is low.
In addition, the cause may also come from air mixing doors, air distribution doors or inaccurate air vent control motors.
When uneven cooling appears, the car owner should take the car to a reputable repair facility to check the pressure of the refrigerant, the operating capacity of the compressor as well as the entire air distribution system.
Identifying the correct cause will help with effective repair, avoid unnecessary component replacement, and maintain stable cooling performance.
