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

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

Charging the air conditioning is one of the most important tasks to check if we do not want our car to turn into a four-wheeled oven.

. Firstly, it is important 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 air conditioning capacity. But then, how is the air conditioning charged? "The charging is carried out using an air conditioning charging station", points out 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, amongst other things". This device is responsible for recovering the refrigerant fluid from the vehicle (fluorinated gas), cleaning it and dehydrating it, as moisture is the first enemy of air conditioning. "In vehicles of a certain age, the gases they come with as 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 currently used. "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 circuit. The machine starts to operate with the cleaning and recovery of the 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 charge is carried out. Once the process is completed, a check is made to ensure the air conditioning is working correctly. Below we provide a video explaining how one of these charging stations works.
