Vehicle Needs To Be Recharged and Freon Leak
One of the most common reasons why your air conditioning system is not getting cold may be due to low freon and needs to be recharged. Your a/c needs recharging because it is suffering from a freon leak. Automotive air conditioning systems are kept under pressure and sealed. Different manufacturers contain freon in their own unique way. In essence, freon is measured by weight- in grams or ounces. The only way to measure the amount of freon in your air conditioning system is to remove it with a specialised machine and refill the system with the right amount. Freon leak may not be a major cause of concern as older a/c systems naturally leak freon over time. Some amount of leakage is expected over a period of a few years, but this problem should not persist for a few weeks or months. In the case that your a/c has been leaking for over a month, this issue needs to be resolved by a skilled auto mechanic. A vehicle’s air conditioning system is typically made of rubber and gaskets that experience failure or malfunction over time; hence it is commonplace to have them replaced when they start showing signs of failure.
Freon is a chemical whose function is to cool the air inside the cabin. The automotive industry has replaced R12 and R134 to T1234yf. The latest car models feature newer freon that are generally safer for the environment.
To resolve the issue of freon leak, you need to recharge your car’s refrigerant. If you aren’t too comfortable doing it yourself, you can always seek the expertise of experienced car mechanics for proper and efficient recharging.

The Air Conditioning Compression is Not Engaging
This specific issue is due to a number of reasons. Failure usually occurs when there is electrical fault in the circuit or clutch of your compression. Another reason is that of low freon levels, and lastly, the vehicle may overheat. As most cars are controlled by computers, one of the first signs that signify engine failure is that of the a/c system not turning on immediately. In this instance, the malfunctioning part needs to be replaced by a reliable car mechanic in Sydney.

The Blend Air Door is Stuck
The small hatch inside your vehicle’s ventilation system is called the blend air door. When you switch your a/c from heat to cold, the door is expected to change its position to draw in cold air. Even in the presence of a malfunction, your a/c will still be working property but draw heat from the engine. In this case, you may be experiencing mechanical issues with the blend door or the very motor that ensures its proper functioning. Whatever the reason for the malfunction, it is recommended to get your a/c checked regularly. If you do not have the expert knowledge to fix it by yourself, obtaining the services of an auto mechanic in Sydney is the best way to go.

You Can Feel Cold Air, But Not Blowing
Your a/c is not working because there may be air flow restrictions within the car dashboard. The resolution is as simple as changing one of its wires, a replacement of the fan unit, or a switch to a new evaporator core. These activities are something that should be left in the hands of professionals as it involves taking apart the dashboard area and access to various complex components of the car.
A vehicle’s air conditioning system is rather complicated. While there are quick fixes to its common issues, such as adding Freon, the other solutions require in-depth understanding and knowledge.
