Top Causes of HVAC Airflow Problems

One of the most prevalent problems associated with HVAC systems is airflow issues. If you notice that your system outputs too much, too little, or incorrectly heated or cooled air, it’s important to get to the bottom of the issue as soon as possible. By addressing the problem immediately, you can prevent future damage and get back to enjoying the benefits of a fully functioning HVAC system. To determine the source of the issue, check out this guide on some of the top causes of HVAC airflow problems. 

Clogged Filters

Clogged filters are one of the most common and easily resolvable causes of HVAC airflow issues. Over time, the filter in your HVAC system will collect a significant amount of dust and other debris in the air. If the filter accumulates too much debris, air won’t be able to flow through it. As a result, your system won’t be able to output an ample amount of temperature-controlled air. To prevent your filter from getting clogged, make sure to change it regularly according to the instructions in its owner’s manual.

A Blocked Condenser Unit

Another one of the top causes of HVAC airflow problems is a blocked condenser unit. Typically, condenser units are located outside of one’s home. As such, they may get blocked with leaves, twigs, and other debris, which will prevent air from being sucked into the unit and pumped into the house. Fortunately, you can easily rectify this airflow issue by simply removing the debris around the exterior unit.

Obstructed Vents

Are you sensing a pattern? Yet another way in which obstructions can cause airflow issues is when vents become blocked. To allow an ample amount of air to flow out of your HVAC system, make sure to clear the area around its vent. Ideally, you should avoid placing any objects or furniture within 18 inches of a vent for an HVAC system for optimum airflow. 

Dirty Condenser Coils

Dirty condenser coils are also a culprit for many HVAC airflow problems. For optimal performance, you should clean the coils on your HVAC system at least once or twice a year. Forgoing such maintenance will likely cause the coils to get so dirty that they aren’t able to release the heat they absorb from the air in your home. As a result, your HVAC system won’t work as effectively, and you will likely experience airflow issues, among other operational problems.
