It's hard to imagine a car trip without air conditioning, especially in the summer. To avoid its failure, it's worth following a straightforward rule. Check how to use air conditioning properly.

When the temperature outside exceeds 30 degrees Celsius, entering a pleasantly cooled car is a natural relief. However, sometimes the air conditioning can fail. To avoid this, it's worth following the so-called 5-minute rule.

How to use car air conditioning smartly?

Most cars, including older models, are equipped with air conditioning. It allows for a comfortable ride regardless of weather conditions. Unfortunately, air conditioning is a vehicle's most frequently failing part. However, you can reduce this by following the 5-minute rule. What does it involve?

Five minutes before your planned arrival, turn off the cooling but leave the blower on. This will let the cooler adjust to the prevailing temperature, and the fan will "absorb" the already accumulated cold and moisture. Doing so will reduce the humidity in the air conditioning system, preventing the growth of fungi and mould. These microorganisms can cause throat infections and colds. You should use this method every time you use your car.

Do you remember to disinfect your air conditioning?

As mentioned, reducing the air conditioning system's humidity limits mould and fungi growth. However, this is not a complete solution to the problem. To safely use the air conditioning, disinfect its ducts once a year. You can assign this task to a mechanic or do it yourself.

For this purpose, purchase a disinfectant foam available at car accessory stores and gas stations. The foam kit should include a long tube that you will connect to the foam and insert into the air conditioning duct.

Self-disinfection has some drawbacks, such as the difficulty of checking how far the product has spread. If you decide to disinfect yourself, do it in the spring, as the temperature does not favour the growth of fungi and mould.
