How and when you should charge your car's air conditioning

With summer just around the corner, more than one driver has started to service their vehicle to ensure trouble-free driving on their holidays.

Air conditioning charging is one of the most important tasks to check if we don't want our car to turn into a four-wheeled oven.

First of all, you need to know that the pollen filter is what affects the air conditioning, as it gets dirty with use and filters worse. Furthermore, if it is very clogged, it does not allow sufficient air flow to pass through, which damages the cooling capacity. But how is the air conditioning charged? "Charging is carried out using an air conditioning charging station", says León, "this station is programmed according to the car model, as the charge varies depending on the amount of refrigerant and oil in each vehicle, among other things". This device is responsible for recovering the refrigerant fluid from the vehicle (fluorinated gas), cleaning and dehydrating it, as moisture is the first enemy of air conditioning. "In vehicles of a certain age, the gases that come standard (R12) do not comply with current regulations, so it is necessary to dispose of them according to the European protocol and charge a gas compatible with legislation", adds León. Although the charging procedure has not changed over the years, technology has evolved to adapt to the charging needs of the new gases used today. "We work with gases at higher pressure.

In summary, these would be the steps to charge the air conditioning with the charging station: First, the high and low pressure hoses are connected to the vehicle's circuit. The machine begins to operate with cleaning and recovery of old gas and oil. When finished, a vacuum check is carried out to see if there are any leaks in the circuit. Finally, if there are no leaks, the gas and oil are charged. Once the process is completed, a check is made to ensure the air conditioning is working correctly. Below is a video explaining how one of these charging stations works.
