Common Causes of Weak or Uneven HVAC Airflow

If your Skokie, IL home’s HVAC system can’t properly distribute conditioned air, both your comfort and your wallet are bound to suffer. Weak or uneven airflow is a frustrating problem for many homeowners, but understanding the most common causes can help you respond effectively.

External Airflow Obstructions

If you’re lucky, airflow issues may not indicate a problem with your HVAC system at all. Instead, it could be as simple as a vent that’s been closed or blocked off by furniture. Even a single obstructed vent can throw off the balance of airflow in your system. The same is true of your outdoor condenser unit, which needs a steady flow of air to function correctly. Check around the unit and clear away any dirt, vegetation, or other debris that could be restricting air intake.

Clogged Air Filters

Regularly changing your HVAC filter is one of the easiest and most effective energy-saving measures you can take at home. Unfortunately, many people still don’t do it often enough. Since they’re specifically designed to catch dust and dirt, HVAC filters can become soiled rather quickly. This makes it harder for air to pass through them, which can disrupt airflow throughout your entire system.

Blower Fan Malfunctions

As the name suggests, the blower fan is the component responsible for circulating air through your HVAC system. Over time, normal wear and tear can cause parts of the blower to start breaking down. This may become even more likely if your system is overdue for a professional maintenance visit. In addition to weak or uneven airflow, a failing blower motor often produces other telltale signs as well. This may include loud grinding or squealing noises, excessively high energy bills, and burning odors when your system is running.
