Low Airflow from a Central AC: What Might Cause It

When your air conditioner has poor airflow, it cannot keep up with cooling your home the way it needs to. This can result in a downward spiral of AC problems that ultimately lead to a complete breakdown if left unaddressed. But you can prevent a breakdown simply by scheduling a service appointment to fix the airflow problem. 

Even if you don’t know exactly what is wrong, our team can help you figure it out. Then we can complete your central air conditioner repair in Sugar Land, TX, and get your AC back to working at its best again. Keep reading to learn more about why your air conditioner may have poor airflow and what to do about it.

Blocked Airflow

Sometimes your air conditioner has poor airflow because there is a blockage preventing air from coming in to the system. This can happen when you leave your air filter in place too long and it fills up with dust and dirt. Your air filter can only hold so much before it begins to block airflow going into your system. 

Without enough airflow coming in, there is no air to cool and blow back into your home. If you hold your hand up to an air vent and don’t feel a strong stream of cool air, check your air filter first. If it needs to be changed out, do so. Then wait and see if you notice a difference in how much airflow is coming from the system. If you notice a positive difference–great! If not, something else may be to blame.

Leaks in Ductwork

It’s also possible that you are losing airflow after it gets cooled. Your air conditioner attaches to a network of ducts that transfer cooled air into your home. However, these ducts are made of fragile material that can get damaged easily. Plus, all of the parts are connected together using seals that can wear down over time. 

Even just a few pinprick holes can add up to a lot of air loss. If air escapes before reaching your home, the result may be poor airflow coming from the vents. Our team can pressurize your ducts to identify any holes so that we can seal them off and ensure that all of the cold air your unit produces reaches the rooms of your home.

Frozen Coils

Other times, poor airflow happens because there are frozen coils inside of your air conditioner. While sometimes poor airflow coming into your system can cause frozen coils, there can also be other causes. For example, if you have a refrigerant leak then ice may develop on the coils. 

A refrigerant leak can increase the humidity levels around the coils and then when the remaining refrigerant cycles through, this humidity crystallizes into ice. It’s a cycle that continues until the ice is thick enough that it is blocking your air conditioner from being able to cool your home effectively. The result is poor airflow and lack of cooling.
