In winter, how to use car air conditioner properly?

Even though it's cold, you should still turn on the car's air conditioner.

According to car experts, in cold weather, you should use the air conditioner at least once a few weeks (about 10 minutes each time) to ensure that the coolant is still circulating in the system. This will help lubricate the rubber linings through the coolant's components, ensuring that the pipes operate properly.

On the contrary, when the air conditioner is not used for a long time, the rubber parts will not be lubricated, leading to leakage and depletion of coolant. This causes the car to suffer more changes in air pressure; sometimes the rubber pads will have to be replaced because they lose their ability to seal and retain air.

In addition, car air vents are susceptible to moisture, mold, and bacteria when the air conditioner is not used regularly; when the air conditioner is turned back on, "dirty" air will be blown into the car.

In addition, car air conditioners also have a drying function, removing moisture in the environment, so they are very useful in winter. When used, the air conditioner system helps prevent car windows from fogging up, condensing, and keeps the environment in the car from becoming humid.

Turn on the air conditioner at a reasonable temperature

Many drivers wonder what temperature they should set in the car in the winter when it is very cold? To warm up or cool down? According to car experts, the temperature should be set to a temperature that the body feels comfortable; it does not need to be warmer than outside, just not cold.

The driver needs to switch the car's air conditioner to heating mode, keeping the air conditioner running, dehumidifying the car, lubricating the system and keeping the person warm.

Like winter in the North, the suitable temperature range is about 20 - 26 degrees Celsius. Before getting out of the car, you should turn off the air conditioner or reduce the temperature to help your body adapt, avoiding heat shock when going outside, especially for children and the elderly.

Why do glasses fog up when the air conditioner is on in winter?

This phenomenon occurs because the air conditioning system has not been operated for a period of time, so moisture has accumulated. When starting up, the air conditioner blows moisture into the car, fogging up the windows.

If the glass fogs up for more than 1 minute, the cause may be that the car owner has the air conditioner on “recirculation” mode, taking in air from the cabin. The breath of passengers in the car contains moisture and the car’s air drying system cannot dry it fast enough, resulting in the car’s environment remaining humid and the car’s glass fogging up.

Accordingly, turning off the “recirculation” mode will solve the problem of foggy windows. If the windows are still foggy, it means that the air conditioner or cooling system of the car is malfunctioning, the car needs to be checked.
