Reasons Why Vehicle AC May Not be Working - information from the the pros at Shingle Springs Subaru serving Sacramento, CA

When you turn on the A/C in your Subaru, it should blow cold air. If it doesn't, there's a problem. Sure, it's especially important in the summertime, but it can be useful year-round. Even if it's just 70 degrees outside, leaving your Subaru in the sun for half an hour can make the interior temperature climb to 100 and beyond.

That's why we recommend scheduling a service appointment for your Subaru if the A/C isn't working. But before you can come in, it may be helpful to know more about what may have caused the system to fail. So, we look at five reasons you may be having problems with the air conditioning in your car. If you have any questions, please contact us at Shingle Springs Subaru.

5. Refrigerant Leak

Refrigerant is the heart of your vehicle's A/C system, and the way it works is unusual. It starts out as a liquid and turns into a gas when it absorbs heat. As the heat dissipates, the refrigerant turns back into a liquid, and the process begins again. If the refrigerant is leaking, your A/C system won't have what it needs to run well. And while a refrigerant leak may be hard for you to find, it's easier for our expert technicians. Typically, they'll perform a dye test to pinpoint exactly where the leak is coming from.

4. Compressor Problems

The compressor is the part of the A/C system that pressurizes the refrigerant, allowing it to circulate through the system. If the compressor isn't working as it should, the refrigerant won't be able to go through the cycles necessary to cool things down. If the compressor has gone bad, you'll most likely need a new one to set things right.

3. Condenser Problems

The condenser is the component that cools down the gaseous refrigerant, turning it into a liquid once more. If the condenser is damaged, it may not function well (or at all). The condenser may simply be blocked rather than physically damaged; if this is so, then there's a chance it can be unblocked. However, if it's sustained actual damage, it will need to be replaced.

2. Electrical Issues

It's possible that an electrical problem may also be the cause of A/C issues. To start, try replacing the A/C fuse. If this solves the issue, great! However, if the fuse blows again soon, or if replacing the fuse does nothing, then your Subaru likely has deeper electrical issues that need to be diagnosed by expert technicians.

1. Clogged Cabin Air Filter

Of course, the problem could be something as simple as a clogged cabin air filter. If this is what's causing the problem, then replacing the filter will let the cool air start flowing once again.
