Troubleshooting Common AC Issues

Most people don’t think about their air conditioner until it stops working, and by then, it’s often too late. You may be experiencing any number of issues, from a lack of airflow to an inability to create cool air.

If your AC is giving you problems, don’t worry – we’re here to help! In this blog, we will discuss the most common AC issues and what can be done to troubleshoot them. So if your AC is acting up, read on for tips on how to get it fixed!

Lack of Airflow

One of the most common AC issues is a lack of airflow. This can be caused by a variety of factors, from dirty air filters to blocked vents.

If your AC isn’t blowing enough air, one of the first things you should check is your air filter. If it’s been a while since you’ve replaced it, it may be time for a new one. A dirty air filter can block airflow and make your AC less effective.

If your air filter is clean but you’re still not getting enough airflow, it may be due to blocked vents. Make sure all your vents are clear of furniture or other objects that could be blocking the flow of air. A bad blower could also be the culprit, as air won't be circulating from your AC through your vents.

If none of these solutions solves the problem, you may have a more serious issue with your AC. In this case, it’s best to call a professional for help.

No Cool Air

Another common issue is that your AC isn’t blowing cool air, even though it’s turned on to a low setting.

If this is the case, one possible solution is to clean the coils. Dirty coils can prevent your AC from cooling properly, so it’s important to keep them clean.

You can clean the coils yourself with a brush or cloth. Just be careful not to damage them while you’re cleaning!

If cleaning the coils doesn’t solve the problem, it may be time to call a professional. They can help you troubleshoot other possible issues with your AC.

Weird Smells

Nobody wants their home to smell weird, but unfortunately, this is a common issue with ACs. If your AC is emitting strange smells, it could be due to mold or bacteria growth in the unit.

To get rid of mold or bacteria, you’ll need to clean your AC unit. This can be done by using a special AC cleaning solution or a DIY mixture of vinegar and water.

Once you’ve cleaned the unit, the smells should go away. If they don’t, there may be another issue at play. In this case, it’s best to call a professional for help.


If your AC is overheating, it could be due to a variety of factors. One possible cause is dirty coils. The coils in your AC unit can get clogged with dirt and dust over time, which can restrict airflow and cause the unit to overheat.

Another possible cause of overheating is low refrigerant levels. If your AC is low on refrigerant, it won’t be able to cool your home properly, which can cause the unit to overheat.

If your AC is overheating, the first thing you should do is clean the coils. If this doesn’t solve the problem, you may need to call a professional to check your refrigerant levels.
