5 Most Common HVAC Airflow Problems and How to Fix Them Airflow difficulties are one of the most common HVAC problems. It can be extremely inconvenient if your air conditioner isn’t cooling your home properly during the summer months. HVAC airflow difficulties can cause a system to temporarily collapse.

Airflow abnormalities usually cause problems with the air conditioning system at home or even in the workplace.

5 Most Common HVAC Airflow Problems

Poor circulation inside the air conditioning system can be caused by a variety of factors, including dirty air filters and leaky ductwork. Some of them are simple to fix, while others require the expertise of a professional.

Clogged air filters: HVAC air filters should be cleaned periodically or more frequently, depending on the activity. They remove mold, dirt, pollen, pet dander and other contaminants from the air. If you leave your filtration clogged for too long, your air conditioner may stop working properly.

Clogged ducts: Dust and dirt can clog your ductwork due to lack of management. It can also create holes or breaks through which air can escape. All of these concerns result in lower airflow for air conditioning systems.

The vents are clogged: Inspect your ventilation if you find that the system is not effectively cooling your room. Sometimes you might be unintentionally blocking your air vents. This process reduces HVAC airflow, making you stuffy and unpleasant in the hot summer.

Thermostat error: HVAC airflow problems can be caused by something as simple as a broken thermostat or perhaps even faulty equipment. However, if your thermostat has stopped working or is not properly calibrated, it can affect your HVAC airflow.

Old HVAC system: The device becomes sluggish as it ages and cannot maintain optimal airflow. If you notice a significant decrease in the airflow of your air conditioning system, your unit may be at the end of its life.

How to Fix Common HVAC Airflow Problems

We’ve combined a list of the most common solutions to prevent and fix airflow problems with HVAC systems:

  • Blocked air filters can cause airflow problems in your HVAC. To resolve this HVAC airflow problem, replace the air filters with new filters from Custom Filters Direct. Keep in mind that your air filters should be changed at least once every 2-3 months.
  • Leaks are primarily to blame for low refrigerant levels in your air conditioning unit. In this case, contact an HVAC professional to replace the coolant; the levels should match the levels listed by your AC manufacturers.
  • A faulty thermostat can affect the airflow in your HVAC system. If you have a battery-operated thermostat, inspect the batteries first. If the batteries seem fine, open the cover and inspect for dust and dirt. Items inside can bend causing problems.


Improper and inappropriate airflow can lead to long term difficulties. This results in an unpleasant feeling with poor air quality, which can potentially harm your health. If you find that the HVAC system isn’t working as well as it used to, you may need the services of an HVAC professional to examine, diagnose, and repair the problem.
