Here are the most common causes of malfunctioning car A/C systems:

1. Insufficient refrigerant: This is often the main issue when the air blows hot. Low refrigerant levels are usually caused by a leak, which can be due to worn hoses or loose connections. You can refill the system with a recharge kit from an auto parts store. However, this approach has its drawbacks. It could lead to overcharging the system, affecting its performance, and it doesn't address the underlying leak causing the problem.

2.Defective compressor: If the compressor fails, the entire A/C system won't work. The compressor's clutch, which connects it to the pulley powering the system, can be the culprit in some cases. This is a relatively minor repair. In vehicles with belt-driven A/C units, the clutch allows you to turn the compressor on and off. (Note: Electric motor-driven A/C units in hybrids and EVs don't have a clutch.) Sometimes, the problem can be as simple as a blown fuse.

3.Faulty pressure switch: There are two pressure switches that monitor the refrigerant. If the pressure becomes too high or low, the compressor will shut off for safety reasons, resulting in a non-functional A/C system.

4.Damaged condenser: The condenser, located in front of the radiator, cools the A/C refrigerant. Debris striking it can cause clogs or damage. Aging and wear can also contribute to condenser failure. Typically, a car's A/C condenser needs replacement after about 10 years of regular use.

5. Malfunctioning condenser fan The condenser relies on a fan to cool the refrigerant in the A/C system. If the fan stops working, you may notice that the A/C doesn't cool the cabin as effectively at lower speeds. You might also hear unusual noises like banging or rattling, and the fan won't run when the car is parked.

6. Sensor malfunctions The climate control system in a vehicle relies on various sensors to accurately regulate the air temperature. If any of these sensors fail, it can affect the system's performance.

7. Blocked cabin air filter To keep dust, pollen, and other particles out of the cabin, a car's climate control system uses a filter. If this cabin air filter becomes clogged and is not regularly replaced, it can impact the cooling capabilities of the system.

8. Defective blend door actuator An air conditioning system has a blend door actuator that directs hot or cold air into the cabin. If you set the system for one temperature and get the opposite, it may be due to a malfunctioning actuator.

9. Faulty head unit If all other components of the system are functioning correctly, the central control unit (where the temperature controls are located) may be the issue. This could be caused by wiring problems or, in newer vehicles, a problem with the electronic signal that connects the computerized temperature controls to the mechanical A/C components under the hood.

Reasons why compressors are prone to failure in summer

Air conditioning compressors can fail in the summer due to a variety of reasons. One of the main factors is increased usage during hot weather. The compressor has to work harder to cool the air, putting more strain on its components and potentially leading to failure. Additionally, the increased heat can cause the refrigerant to expand and put extra pressure on the compressor, leading to potential damage.

Another reason for compressor failure in the summer is lack of maintenance. If the compressor is not regularly serviced and maintained, it can become dirty or clogged, affecting its efficiency and eventually causing it to fail. It is important to clean or replace filters, check refrigerant levels, and ensure proper lubrication to keep the compressor running smoothly.

Furthermore, running the air conditioning system improperly can also contribute to compressor failure. For example, if the system is not used regularly or only used at low settings, it can lead to the refrigerant not circulating properly, causing damage to the compressor.

To prevent compressor failure in the summer, it is recommended to have regular air conditioning maintenance performed, including cleaning or replacing filters, checking refrigerant levels, and ensuring proper lubrication. It is also advisable to use the air conditioning system regularly and at the recommended settings to maintain its efficiency and prevent potential damage.
