No air conditioning or only weak

Decreased efficiency or complete cooling failure is the most common condition of the air conditioning system and in most cases there is a lack of cooling medium. It is a compound of fluorine, carbon and hydrogen. Unlike the previously used R12 medium, it does not contain chlorine and does not damage the ozone layer. Since the system is operating at relatively high pressures of around 20 bar, the new car delivers little refrigerant leakage through hose material, seals and compressor (it can reach up to 30% per year on the new car), after years of operation microscopic cracks in the capacitor itself is evident. If there is no mechanical damage to the system (for example in an accident), it takes several years during which the air conditioner is operating normally, but with a significant refrigerant leak, the efficiency of the air conditioning is reduced, and when the pressure drops below a certain level, the control electronics will no longer allow the compressor to run so it becomes inoperative.

Label with data on the quantity and specification of the coolant and oil for the compressor

The cooling medium also carries vital lubricating oil for the compressor, which, in its absence, can withstand. Now you practically have nothing left to do but visit a service that will also advise on maintenance of air conditioning. They are equipped with so called fillers, which, after being connected to the air conditioning system of the car, first vacuum the remaining refrigerant, then a vacuum test are carried out, whereby greater leaks should be shown. If the system maintains a vacuum for a set period of time, the refill is filled with coolant, compressor oil and possibly a substance that reveals leaks under the UV light in the system. Each car has an exact amount of coolant and oil to be in the system.

Connector for filling the air conditioning system

Coolant refills and the associated service will most likely cost you from 500 to 1,000. Serious company will not charge you the entire amount of refrigerant contained in the system but only the missing part, as it is recyclable, and after the work is done it will also perform low pressure and high pressure diagnostics and air conditioning output measurement. As mentioned above, a defective compressor may also become a malfunctioning air conditioner. With a well functioning air conditioner, it can be heard quite clearly in older cars (up to the year of production in 2004) when the engine is started, how the compressor clutch clicks on when the engine is engaged, at the same time increasing the idling speed.

Air conditioning smells

As far as the ventilation system is concerned, when the air conditioner is turned on, it is a bacteria and fungus that is deposited in the evaporator. They will help you in the service and disinfect the entire system with a special spray. Cleaning can also be done by self help and goes out to several hundred. Due to the high dustiness that is on our roads, the workshop recommends to replace at least every two years the cabin (saw) filter that cleans the air coming into the ventilation system. Even this can be done by self help, and it is a matter of several hundred.
