Why is my Subaru Legacy AC not blowing cold?

Possible Reasons for Subaru Legacy AC Not Blowing Cold
When the AC in your Subaru Legacy isn’t blowing cold air, there could be several reasons for this issue. Here are some possible causes based on the information from various sources:
Low Refrigerant Level: One of the most common reasons for the air conditioner not blowing cold air is a low refrigerant level. Insufficient refrigerant can hinder the proper functioning of the AC system.
Electrical Problems: An electrical problem, such as a blown A/C fuse or deeper electrical issues, could also be the cause of the AC not working properly. If the A/C fuse blows again soon after replacement or if replacing the fuse does nothing, it may indicate deeper electrical issues that need to be diagnosed by expert technicians.
Compressor Malfunction: A malfunctioning compressor could be another potential cause for the AC not blowing cold air. If the compressor is not functioning properly, it can lead to the air conditioner blowing hot air.
Clogged Components: Clogged components such as the cabin air filter, condenser, or evaporator coils can also hinder the normal operation of the air conditioning system in your Subaru Legacy. These components need to be clean and free from obstructions for the AC to function effectively.
Blower Motor Issues: A defective or sluggish blower motor can also lead to reduced or no air flow from the vents, resulting in the AC not blowing cold air. If the blower motor fails, it may need to be replaced with a new one.
Other Potential Causes: Other less common causes for the AC not blowing cold air in a Subaru Legacy include a clogged expansion valve or orifice tube, overcharged oil, a faulty blend door actuator, or a defect in the climate control unit.
It’s important to have these potential causes thoroughly diagnosed by a qualified technician to accurately identify and address the specific issue with your Subaru Legacy’s AC system.

What does a refrigerant leak look like?

Perhaps you’ve noticed warm air or lower than normal airflow coming out of your system’s registers or you’ve heard a hissing sound. Maybe you’ve observed water on the floor by your HVAC unit or seen ice forming on your evaporator coils. These are all telltale signs of an AC refrigerant leak.

How much does it cost to recharge AC in car?

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 is the AC in my Subaru not working?

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 is my Subaru Legacy AC not blowing cold air?

The most common reasons a Subaru Legacy ac isn’t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

Why is my Subaru AC only cold when driving?

FAULTY CONDENSER FANS
Defected condenser fans can be among the major causes when air conditioning only works when driving. Condenser fans help reduce the refrigerant’s temperature to ensure it condenses. Malfunctions in condenser fans can prevent this from happening.

How do I fix my AC not getting cold?

First, check your filters and coils for dirt and debris that may be impeding airflow. Once you’ve cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn’t blow cold air, it could be that refrigerant levels are too low.

Should I turn my AC off if it’s not cooling?

If your AC isn’t cooling (but is on and blowing warm air), it’s best to turn it off and take the time to troubleshoot what’s causing the problem. Refrigerant leaks (also called Freon leaks) can cause an air conditioner to not cool properly and can be hazardous to your health or cause refrigerant poisoning.

How do I fix my AC blowing warm air?

AC Blowing Warm Air? Try These 3 Solutions First

1. Step 1: Check Your Thermostat. Switch thermostat mode to “Cool” Is the AC fan set to “Auto” or “On”?
2. Step 2: Check Your Breaker/Fuse Box. Locate HVAC Breaker or fuse. Ensure HVAC breaker or fuse has not been tripped or blown.
3. Step 3: Check Filter. Unplug AC Unit.

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.
