Why is my car air conditionern’t cooling? Why is the car air conditioner not cooling? What causes car air conditioner problems?
A large portion of the country experiences extreme heat in summer. Air conditioning systems are standard equipment in vehicles to combat this heat. To ensure proper operation of your air conditioning system (A/C), you must regularly check and maintain it. Even though air conditioning systems have seen significant improvements in design, it is still possible to experience problems.
Your vehicle’s air conditioning system can be complicated because of where the lines and hoses are located. Your vehicle’s air conditioner compresses and presses the gas. Then, it releases pressure which causes it to lose heat quickly and cool down. This heat is absorbed from your vehicle’s interior and repeated repeatedly until you achieve your desired temperature.
Why does the car air conditioner not blow cold air?
There are many reasons that your car’s air conditioner is not cooling properly when you need it. These are the top reasons your car’s air conditioner doesn’t cool properly.
1. Low Levels of A/C Gas/Leaks
Low refrigerant levels are the leading cause of an air conditioner not cooling correctly. The most common reason for the air conditioner not cooling properly is a low level of refrigerant. It could be caused by a damaged or loose hose, or even a loose connection. It is important to locate and repair the leakage before refrigerant is reintroduced.
Over time, even the most powerful air conditioners may lose some of their effectiveness. This happens slowly, and the cooling effect can be decreased by several degrees. Refrigerant should always be checked and replenished if your car isn’t cooling properly.
2. Overfilling A/C Gas
Excessive pressure, just like low refrigerant levels, can cause the A/C to stop cooling. High pressure can lead to system suffocation if the refrigerant is not filled to its full capacity.
3. Restrictions in the Pollen Filter / Air Conditioning System
Air conditioning system problems can also lead to insufficient cooling. Blockages in the system piping cause changes in the system pressure and block the flow of refrigerant.
The cabin air filter (also known as the pollen filter) cleans out dirt, dust, pollen and other contaminants from the air entering the passenger compartment. It keeps the air conditioner evaporator clean. This ensures that the air conditioner evaporator cools at maximum efficiency and helps to prevent the growth of bacteria which can lead to musty odors. If you notice a decrease in air flow through the ventilation channels or bad odors when your air conditioner turns on, it is possible that the pollen filter may be clogged.
4. Air/Moisture Pollution
To ensure that the vehicle’s air conditioner system operates at its peak efficiency, it must not be polluted by moisture or air. Even the smallest amount can cause uneven pressures within the air conditioning system. Air is often accidentally introduced to the system by using a charging device. The system’s dryer and accumulator can be damaged by excess moisture.
5. Defective A/C Fan
Faulty fan motors could be another reason your air conditioner stops cooling. A malfunctioning fan motor can cause a reduction in cooling efficiency. To maintain system pressure under control, the condenser needs to have sufficient airflow. A cooling fan failure could be the reason your vehicle isn’t blowing cold air while idling but returning to normal at acceleration.
6. Defective Heating Valve
The heater heats up and hot engine heat enters your car when you turn it on. If you want to cool your car by turning on the air conditioner, there is an element in the ventilation system called “The”. “heater flap” Turn off the hot air coming in to the cabin, and switch on the cold air from the air conditioner system. If the heater flap is damaged or stuck, problems with the hot or cold air system could occur.
7. Damaged or Clogged Capacitor
Condenser functions to convert air conditioner gas to liquid. If the condenser gets clogged, or is damaged, then the refrigerant flow is limited. The air conditioner system will stop blowing cold air and can’t cool the vehicle as needed. Most vehicles have the capacitor located at the front. If anything is blocking it, it should be visually checked. It may be broken completely if there is nothing blocking it.
Sometimes, air conditioner malfunctions are inevitable. Simple maintenance can help to avoid such problems. Air conditioning systems of many makes and models typically last 150,000km. is approximately.
