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

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

Air conditioning charging is one of the most important tasks to check if we don't want our car to turn into a furnace on wheels.

. First of all, it's important to know that the pollen filter is what affects the air conditioning, as it gets dirtier with use and filters worse. Furthermore, if it becomes very clogged, it doesn't allow sufficient airflow to pass through, which impairs the climate control capacity. Now then, how is 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 quantity 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 it and dehydrating it, as moisture is the first enemy of air conditioning. "In vehicles of a certain age, the gases they carry as standard (R12) do not comply with current regulations, so it is necessary to dispose of them according to European protocol and charge a gas compatible with legislation", León adds. Although the charging procedure has not changed over the years, technology has evolved to adapt to the charging needs of the new gases currently in use. "We work with gases at higher pressure.

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