The hot and humid summers in South Jersey can be unbearable, but nothing’s worse than when your car’s air conditioning system starts blowing hot air. This situation unfortunately happens more often than we’d like. So why is your car’s AC blowing hot air?

There are a number of reasons why the AC unit in your vehicle is blowing hot air, and Prestige Subaru is here to help you understand each one. We’ve compiled a list of some common AC issues that could cause the system to blow hot air and a few tips on how you can fix them.

Old Compressor

The compressor is a critical component of your vehicle’s air conditioning system. It allows the refrigerant to flow through the system to cool down the interior of your car. With time, the part will start to wear out and even stop working all together, which can cause the system to start blowing hot air.

Having a professional inspect and repair the part is the most effective way to fix this issue. On top of that, there are also a few ways that can help you extend the longevity of your compressor. For example, running your air conditioning for about 10 minutes once a month can keep the part running in tip-top shape.

Low Levels of Refrigerant

Your car’s air conditioning system needs refrigerant to work properly. When there’s too little, the system can’t produce cold air. Low levels of refrigerant stem from excessive use. A leak within the system can also cause low levels. To determine if your car is suffering from a leak, check the areas around the system’s hose and connections. If there’s oil residue around them, then refrigerant is leaking.

Replacing refrigerant in your vehicle isn’t a DIY kind of job. Only those with a specific license can purchase and handle refrigerant and add more to your car. So your best bet is to schedule an air conditioner service appointment to remedy this issue.

Clogged Systems

With time, some parts of your system can get clogged with dust, debris and other particles. This blocks overall airflow as well as the flow of refrigerant resulting in the system blowing hot air.

The most troublesome clogs happen in the expansion valve and hose. The expansion valve allows the refrigerant to flow to the evaporator to produce cold air. If it’s clogged, the fluid won’t be able to reach the evaporator, so the system starts to blow hot air.
