Why is my AC blowing hot air Subaru?

Possible Reasons for AC Blowing Hot Air in a Subaru
There can be several reasons why your AC in your Subaru is blowing hot air. Here are some possible causes based on the search results:
1. Low Refrigerant Charge: One common reason for the AC blowing hot air is a low refrigerant charge. As the refrigerant level decreases, the AC system may not be able to cool the air effectively.
2. Leaking Evaporator Coil: Another possible cause is a leaking evaporator coil. If the evaporator coil is leaking, it can prevent the AC compressor from receiving the necessary oil to function properly, resulting in warm air blowing from the vents.
3. Faulty AC Compressor Clutch: A faulty AC compressor clutch can also cause the AC to blow hot air. If the clutch gap is out of specifications, it may not engage properly, leading to warm air instead of cold air.
4. Mix Door Stuck Open: The mix door, which controls the blend of hot and cold air, may get stuck in the open position. This can result in warm air being blown into the cabin even when the AC is turned on.
What to Do if Your Subaru AC is Blowing Hot Air
If your Subaru’s AC is blowing hot air, here are some steps you can take:
1. Check Refrigerant Level: Have a professional check the refrigerant level in your AC system. If it is low, they can recharge it to the appropriate level.
2. Inspect for Leaks: It’s important to check for any leaks in the AC system, particularly in the evaporator coil. If a leak is detected, it should be repaired to prevent further issues.
3. Have the AC Compressor Clutch Checked: If the AC compressor clutch is suspected to be faulty, it should be inspected and, if necessary, replaced by a qualified technician.
4. Address Mix Door Issues: If the mix door is stuck open, it may need to be repaired or replaced. A professional can diagnose and fix this issue.
It’s recommended to take your Subaru to a certified Subaru dealership or a trusted automotive service center to diagnose and address the specific issue with your AC system.
Remember, these are just possible causes based on the search results. It’s always best to consult with a professional to accurately diagnose and resolve the issue with your Subaru’s AC system.

Why is my AC not blowing cold air in my Subaru?

The first possibility is that there is a refrigerant leak. The leak may be found in the evaporator, condenser or hose in which case you should bring your car to a mechanic to be repaired. Another reason that your air conditioner may not be blowing cool air is because the compressor has gone bad.

Why did my Subaru AC suddenly stop working?

The air conditioner will likely stop working altogether if it has a refrigerant leak. Leaks can impact the air conditioner’s cooling ability over time. A Subaru’s engine relies on refrigerant, which absorbs heat, converts it into a gas, and then releases it as a liquid as it transforms back into a gas again.

Why is hot air coming out of AC in car?

One of the most common reasons your car AC is blowing hot air is because of a refrigerant issue—specifically, a loss of refrigerant. This loss of refrigerant can occur either due to a leak or because your car’s refrigerant levels are too low.

Why is my car AC blowing air but not cold?

The most likely reason your air-conditioner isn’t cooling is the car’s air-conditioner is leaking. The car’s AC system needs freon to lower the ambient air temperature and creates some needed cold air. Whenever there is a freon leak on your car there is no way to cool the air.

How do I fix my car AC blowing hot air?

The most common culprits are low refrigerant levels or blocked vents. Low refrigerant can be due to a leak in the system that needs to be repaired, or the system simply not being charged properly. Blocked vents can be caused by debris blocking the flow of air through the vents, and should be checked for obstructions.

How do you fix an AC that is blowing but not cold?

What to Do When Your Air Conditioner Isn’t Blowing Cold Air

1. Check the Thermostat Fan Setting. Is your air conditioner blowing cold sometimes but warm at other times?
2. Replace Your Filter.
3. Inspect the Outside Unit.
4. Check Your Thermostat.
5. Check Your Air Filter.
6. Make Sure There is Electricity Going to Your AC.

How much does it cost to recharge a car AC?

A professional AC recharge cost ranges from $150 – $300 on average depending on the make and model of your vehicle.

Why is my car AC running but not getting cold?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Why did my car AC stop blowing cold air suddenly?

So what caused your air conditioner to stop working? Most likely, your AC system lost its charge of refrigerant. Or, due to an electrical fault, its compressor is not engaging when you turn on the system. Another possibility is that an internal obstruction is blocking the circulation of refrigerant.

Why is my AC suddenly 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.
