Reasons Why Your Air Conditioner Produces Weak Airflow

Wondering why your air conditioner’s airflow is weak? We bet you’re feeling frustrated because of your AC’s weak airflow, especially when the weather is scorching hot. Having inadequate airflow in your unit will make you super uncomfortable on days like these. 

So, let’s take a look at the possible reasons why your air conditioner’s airflow is weak so you can do something about it:

Reason #1: Your Unit May Have a Dirty Air Filter

One of the possible causes of weak airflow is the dirty air filter. Your unit’s air filter is tasked to trap airborne particles circulating through the system and keep them away from the delicate component inside the equipment. Since that is the case, it will definitely accumulate dirt and particles over time. As a result, it will become clogged and will no longer have the ability to remove any more particles from circulation. 

Once your unit’s air filter is completely clogged, your unit will have difficulty circulating air through your home correctly. That dirty air filter will block the airflow, making it difficult for your HVAC equipment to work properly. It has to work harder and use more energy in an effort to achieve air movement, resulting in increased electricity bills and possible damage to your unit.

The only thing you can do to resolve this problem is to replace your air filter. You should have your air filter replaced once a month or once per year to ensure that your HVAC equipment will provide you with optimum air quality. 

Reason #2: You May Have Leaky Ducts or Blocked Ducts

All units must have a sealed duct to carry cooled air from the air conditioner into the inside of a home. If you have leaky ducts, the air will escape before it even gets to your living area, which is why you’re experiencing weak airflow. Blockages can also be the cause of that as it restricts proper air movement. 

Check your ducts for any leakages or blockages, and contact an HVAC technician so they can help you with your unit’s issue. 

Reason #3: There Might Be Something Wrong with the Blower

The blower in an HVAC unit is there to distribute air through your home’s air ducts and vents. If there’s something wrong with it, it will not be able to circulate air properly, resulting in weak airflow. 

If you don’t call a technician right away to check if there is an issue with the blower, you may end up having a unit full of dust, dirt, and grime on fan blades, loose or broken motor belts, or even a short circuit or burned motor. 

Reason #4: There Might Be a Frozen Evaporator Coil

In some cases, the weak airflow may be because of a frozen evaporator coil. Just so you know, a well-functioning AC passes its air over the cold evaporator coil. If the evaporator coil is frozen, it will block the air from passing through smoothly into your air ducts. As a result, there will be weak airflow, or worse, there will be no airflow at all. 

Conclusion

Now that you know the possible reasons why your air conditioner produces weak airflow, it’s time to check your AC for any of these issues. Call an HVAC technician right away when you notice any of these issues. Don’t ignore them! The sooner you have them addressed, the better.
