Why is my Subaru Impreza AC blowing hot air?

Possible Causes of Subaru Impreza AC Blowing Hot Air
There can be several reasons why your Subaru Impreza’s AC is blowing hot air. Here are some possible causes:
1. Low or Overcharged Refrigerant: Insufficient or excessive refrigerant levels can cause the AC to blow hot air. This can be due to leaks or improper charging.
2. Compressor Malfunction: The compressor is responsible for pumping refrigerant throughout the AC system and converting it from a gaseous state to a liquid. If the compressor is not functioning properly, it can result in hot air blowing from the AC vents.
3. Dirty Condenser or Evaporator Coils: Accumulation of dirt and debris on the condenser or evaporator coils can restrict airflow and hinder the cooling process, leading to hot air blowing from the AC.
4. Faulty Blend Door Actuator: The blend door actuator controls the flow of hot and cold air into the cabin. If it malfunctions, it may not properly regulate the temperature, causing hot air to blow from the AC vents.
5. Defective Evaporator Temperature Sensor: The evaporator temperature sensor helps regulate the temperature of the evaporator coils. If it is faulty, it may not accurately detect the temperature, resulting in hot air blowing from the AC.
6. Bad AC Pressure Sensor: The AC pressure sensor monitors the pressure of the refrigerant in the system. If it is malfunctioning, it may not provide accurate readings, leading to improper cooling and hot air blowing from the AC.
7. Electrical Issues: Electrical problems, such as blown fuses or deeper electrical issues, can also cause the AC to blow hot air.
How to Fix Subaru Impreza AC Blowing Hot Air
To fix the issue of your Subaru Impreza’s AC blowing hot air, it is recommended to have the AC system evaluated by a professional technician. They will be able to diagnose the specific cause of the problem and perform the necessary repairs or replacements. It is important to note that working on the AC system may require specialized knowledge and equipment, so it is not recommended as a DIY repair.
If you suspect that the issue may be due to a clogged cabin air filter, you can try replacing the filter yourself. However, if the problem persists or if you suspect deeper electrical issues, it is best to seek professional assistance.
Remember, regular maintenance and servicing of your Subaru Impreza’s AC system can help prevent issues and ensure optimal performance.

Why is my AC running but not blowing cold air?

There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.

How do you diagnose a car AC problem?

Start your vehicle and turn on the AC with the fan on high. Then, cycle through the selector options on your HVAC control, feeling for cold air from each position. Positions that don’t blow cold air may have a temperature sensor issue, while positions that don’t blow any air might have a blend door actuator problem.

Why is my AC in my car suddenly blowing hot air?

Your system, as the amount of refrigerant gas decreases through the leaks, will slowly start to feel warmer. You may not even notice the change. However, one day the system will have lost enough gas, that it no longer functions. That’s when you notice that the fan is blowing warm air.

How do I fix my AC blowing hot air?
