Why is my Subaru air conditioning not working?
If your Subaru's air conditioning (A/C) system is not functioning properly, there could be several potential causes. In this article, we'll explore the common reasons why a Subaru's A/C may stop working and provide guidance on troubleshooting and resolving the issue.
Refrigerant Leak
One of the most common reasons for a Subaru's A/C system to stop working is a refrigerant leak. The A/C system relies on a specific amount of refrigerant to function correctly. If there is a leak in the system, the refrigerant level will drop, and the A/C will not be able to cool the air effectively. Refrigerant leaks can occur in various components, such as the compressor, condenser, or hoses.
Compressor Failure
The compressor is the heart of the A/C system, and if it fails, the entire system will stop working. Compressor failure can be caused by a variety of factors, including lack of lubrication, electrical issues, or physical damage. If the compressor is not functioning, the A/C system will not be able to circulate the refrigerant and cool the air.
Electrical Issues
The A/C system in a Subaru is controlled by an electrical system, and any problems with the wiring, fuses, or relays can cause the system to malfunction. Electrical issues can prevent the compressor from turning on or cause other components to fail, resulting in a non-functioning A/C system.
Clogged or Blocked Components
Over time, the A/C system can become clogged or blocked, preventing the proper flow of refrigerant and air. This can be caused by debris, dirt, or even ice buildup in the system. A clogged condenser, evaporator, or expansion valve can all contribute to a non-functioning A/C system.
Troubleshooting and Repair
If your Subaru's A/C system is not working, the first step is to have a professional technician diagnose the issue. They will be able to identify the root cause of the problem and recommend the appropriate repairs. Common repairs may include recharging the refrigerant, replacing the compressor, or addressing any electrical or component-related issues.
By understanding the potential causes of a non-functioning A/C system in your Subaru, you can better prepare for any necessary repairs and ensure your vehicle's climate control system is working efficiently.
How much does it cost to fix AC in a car?
On average, car AC repair costs run between about $430 and $520. However, if you need a new compressor, you can expect to spend $1,300 to $2,500 or more. Here's a breakdown of some of the most common car AC repairs and their average cost.
What to do if AC is not cooling in car?
How to Check Your Car AC
- Check to see if the cabin filter is clear; if not, replace it.
- Figure out the last time the condenser was replaced.
- When the AC is on, listen to hear the condenser hum as it spins.
- Make sure the condenser is free from leaves, bugs, or other debris.
- Check for leaks in the system.
What is the most common cause of car AC not working?
- Low Refrigerant Levels: - Cause: Refrigerant can leak over time due to wear and tear on hoses or seals.
- Faulty Compressor: - Cause: The compressor is responsible for circulating refrigerant.
- Electrical Issues:
- Clogged Condenser or Evaporator:
- Faulty Blower Motor:
- Thermostat Issues:
- Blocked Cabin Air Filter:
What is the first thing to check when the AC stops working?
the thermostat
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
How do I fix my car AC blowing out hot air?
DIY Diagnosis and Quick Fixes
- First, check the cabin air filter condition and replace it if it's dirty or clogged.
- Check that the heater fan is blowing.
- Clean off the radiator.
- Check all the wiring connections for the AC system that you can access.
- Check the refrigerant level and top it up.
Why is my AC on but blowing hot air?
Common Causes of an Air Conditioner Blowing Warm or Hot Air
These can be due to clogging issues, electrical problems, low refrigerant, evaporator coil malfunctions, or compressor problems. If you've ever had the ac system in your car stop functioning, it's often due to a refrigerant leak or dirty coil.
How to make car AC cold again?
3 Ways to Make Your Car's Air Conditioner Colder
- Clean or Replace the Cabin Air Filter. Your car's cabin air filter is responsible for keeping dust, pollen, dirt, and other pollutants out of your AC and heating vents.
- Check the Refrigerant Level.
- Inspect the Compressor.

Why is my AC running but not cooling?
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 I know if my Subaru AC compressor is bad?
Common Signs of a Failing Subaru AC Air Compressor
- High Cabin Temperatures. One of the very first signs of a failing compressor is the failure of the air conditioner to blow cold air as it used to do.
- Loud Noise.
- Compressor Clutch Not Moving.
Why is my Subaru AC blowing hot air?
Leaking Refrigerant: AC systems are sealed, but over time, they can develop leaks. Leaks can cause a gradual loss of refrigerant, which ultimately results in warmer air blowing from the vents.
