THE ROLE OF EACH AC COMPONENT 

The refrigerant that cools the air and transports it to the condenser is pressurized by the compressor. The condenser then sends the cooled liquid to the accumulator after lowering the temperature and pressure of any hot gas that may flow from the refrigerant. The accumulator is only there if there is also a thermal expansion valve, hence its presence depends on the type of vehicle being driven. The accumulator monitors and regulates the quantity of refrigerant that enters the evaporator, which stores any extra refrigerant, obstructs debris, and eliminates undesired moisture. This particular component separates the gas from the liquid. The thermal valve, which functions in tandem with the accumulator to manage pressure and temperature, decides how much refrigerant should be injected into the evaporator. The evaporator, the system’s last component, controls how cold the air is by interacting with the refrigerant before directing it through the vents of the car.

MAIN CAUSES FOR REPAIR 

In order to make each journey comfortable, the AC system goes through a detailed process of taking heated air, cooling it using refrigerant, and forcing that cooled air into the vents. Multiple indicators show that one of the functions is malfunctioning, allowing the user to spend money on AC repair. Several of the main reasons why an AC system fails include:

• Refrigerant leaks
  
• Inadequate compressor
  
• Accumulation of mold or mildew on the evaporator core

These malfunctions may contribute to some of the warning signs that a car may display when it’s time for AC repairs. Each car uses a liquid refrigerant called freon to cool the hot air. Freon leakage from the cooling system may indicate that the AC system needs to be repaired, according to drivers. Any tiny fracture or hole that permits leaking might stop the air from cooling. Strange noises, unpleasant smells, a moist floor, or temperature changes while you are driving your car are additional indications that your AC system needs to be repaired. Noises like rattling, pounding, or buzzing may be caused by a failing compressor clutch or another serious problem. The most common cause of musty, moldy, and mildewy odours is dirt, debris, or a combination of all three accumulating inside the AC vents. During operation, the AC evaporator unit sucks in warm air and allows water vapor to escape onto the road. The water has nowhere else to go if the evaporator unit becomes blocked with debris. In turn, moldy scents are produced when water drips onto the vehicle’s floor. Because a little refrigerant leak will eventually result in less chilled air or a blown fuse inside the actual unit, a motorist may also notice that the air runs cold and then warm.

WHAT CAN THE DRIVER DO? 

Three precautionary measures are advised by experts to avoid an AC unit from malfunctioning. The first step is to regularly inspect the air filter for any material that might clog the system in order to ensure it is clear. Second, operate the air conditioner for 10 minutes once a week to keep the compressor stimulated and active. Get a complete AC service, third. Regular maintenance ensures that the car keeps on top of little problems that, if ignored, might lead to leaks and expensive repairs. Bring the car to a trained specialist who can perform any necessary AC repairs or fluid refills if any of the aforementioned symptoms occur.
