This Is What Might Be Happening When Your AC Isn’t Blowing Cool Air

Air conditioner are designed to blow air. There’s nothing very difficult about understanding that.

But if an air conditioner suddenly stops blowing air—or if the airflow is severely reduced—then it can be much more difficult to interpret.

Unless you have an expert of air conditioning repair in Hammond, LAdrive down to investigate the system, the cause for your airflow issues are as good as any guess.

If that guess were up to us, however, we assume it could possibly be due to one of the following issues:

The Air Filter is Clogged With Dirt

There are some things that we constantly need to be reminded of. It’s not because any of us are incapable of remembering, but simply because these tasks seem so inconsequential that it’s easy to forget about. We need to be reminded when it comes to tasks like changing the smoke detector batteries, cleaning out the dryer vents—and in the case of air conditioners—changing out the dirty air filter.

The dirty air filter is particularly bad because it can cause a range of serious issues, including a loss of airflow. That filter might imitate the symptoms of the other causes on this list but, upon changing the filter out for a new one, the problem almost immediately goes away.

Moral of the story: change the air filter every three months, and if you’re experiencing any airflow issues, try changing it before doing anything else!

The Evaporator Coil Is Frozen

Surprise, surprise—this is a problem that can be caused by a dirty air filter. However, it can also be caused by a refrigerant leak.

Either way, you’ll know this problem when you see it. Check inside the AC’s indoor unit, where this coil is located. If it appears to be caked in a layer of ice and frost, that’s not because it’s cooling so well—quite the opposite. A frozen coil means that the coil is having a hard time absorbing heat properly, and until it’s fixed, it will block airflow.

The Compressor is Failing

We just talked about the evaporator coil. On the other end of the machine is the condenser coil, and that one sits in the AC’s outdoor unit.

And then there’s the compressor. The compressor helps transfer the chemical refrigerant change phases between the two coils. This is what’s responsible for creating cooled air inside your home.

If the compressor stops functioning, it’s going to prevent cool air from being created. It might not reduce airflow, but you’ll definitely notice that the AC is no longer blowing cool air like it should.

The Ducts Have Significant Leaks and Tears

And finally, we have the ducts.

Your AC might not have a single thing wrong with it, yet, there’s a serious lack of air coming out on the other side. Why?

Most likely, that would be because the air ducts are leaking.

If there are significant leaks and tears in the ducts, your cooled air will get sucked up before it can make it through the other side of the system. In this case, you’ll need some proper duct testing and sealing to fix the problem.
