What Are the Reasons for the Failing Car’s Air Conditioning System?

Car Air Conditioning

Although it is necessary for your comfort, you may still drive safely even without the air conditioning system on. Systems for air conditioning remove odors and contaminants from the air. They maintain clean air and provide health advantages, particularly for those who have respiratory sensitivities. Because of this, the auto air conditioning system must be in good operating order. Failures can happen, just like with any mechanical component. Your car’s feature is in charge of a comfy and leisurely ride.  The air conditioning system in your car may gradually start to leak refrigerant over time, but recharging the car air conditioning to get it to start blowing cold air again is a simple do-it-yourself project that only takes about 15 minutes.

Although one can drive now without, we can only imagine how uncomfortable and perspiration-filled the cabin must be. All cars now come with it as standard equipment; in fact, it is required. The air conditioner is your haven from the oppressive heat and humidity. But does something always function well and as it should? Your car’s air conditioning system is also susceptible to faults and failure. Experts list the top causes of AC system failure in cars in this blog post. Due to complicated mechanical and electrical challenges, there might be a wide range of problems with the Air conditioning system.

Depleted or Leaking Refrigerant

Every air conditioning unit requires refrigerant. The most prevalent and commonly utilized is CFC-12, often known as R-22 or Freon. Chlorofluorocarbon (CFC) Freon has been connected to ozone depletion. Safer compressed gases have been developed because of the effects they have on the environment and human health, including HFC-134a. Heat is absorbed by refrigerants, which then create cool air. There are coils and compressors in your air conditioner. The compressor increases the refrigerant’s pressure. The refrigerant condenses to a liquid condition as it moves through the condenser or coils. After that, it transforms the heat from the outside air into cool air by absorbing it.

The numbing sensation in your car is caused by this cycle. A functioning air conditioner needs refrigerant to operate effectively. The air conditioner ceases to function properly when there is a refrigerant-related problem or leak. The heat pump may corrode or there may be a loose connection, which might result in refrigerant leakage. Over a year, your air conditioner may lose 10 to 15 percent of its refrigerant. That represents a loss of refrigerant of at least 50% over five years.

Compressor and Coil Failure

The condenser’s job is to condense the compressor-produced, pressurized water refrigerant water vapor. A network of fans and coils make up the condenser. Dust or dirt buildup could obstruct the condensing system or air conditioner coils. Additionally, they could rust and leak. As a result of continuously trying to vent hot air, the air conditioning system overheats.

Ineffective Blower or Fan System

The air is circulated via the coils of the condenser system fan. The airflow will continue to be warm even if the condensing system fan fails.

An evaporator that is faulty or frozen

Failure may occur if the air conditioning system begins to blast warm or hot air before abruptly switching to cold air. Your air conditioner will frequently alternate between the hot and cold settings if the evaporator is broken. The evaporator will produce warm air, just as condensation does with cool air. For a deeper understanding of this section, please read our article on how a car’s air conditioner operates. The evaporator might also freeze because it comes into touch with the refrigerant. Evaporation cannot effectively cool air if it is covered in ice. Before the system can distribute cold air once more, it must wait until the ice melts.

Bad Orifice Tubes and Expansion Valves

The orifice tubes and expansion valves are the main elements of an automobile’s air conditioning system. The evaporation can overheat if there is insufficient refrigerant flowing, and it can freeze if there is too much. Ice-cold air emerging from the air vent is a glaring indicator of this.

The Compressor, the AC’s Brains

One of the most important parts of a car’s air conditioning system is the AC compressor. For the AC system to operate correctly, it must be pressurized and kept refrigerant flowing. Every moment the Aircon is turned on, it is susceptible to wear since it runs in a constant cycle of on and off. It will ultimately break down and require replacement, similar to any other part of a car. The refrigerant is pressurized and distributed by the compressor. The remainder of the Air conditioning system will be impacted if there is a compressor issue.

Final Words

If your air conditioner seems to have a problem, this part may be broken. As according to Brainerd Compressor Inc., the two most common reasons for compressor failure include loss of oil and slugging.
