3 Common Causes of Airflow Issues in Your HVAC System and Home

June 15, 2020

Air ducts and vents play a critical role in the comfort and indoor air quality of your Wadsworth, OH, home. The ducts and vents deliver the warmed or cooled air from your heating and cooling system. Low airflow negatively impacts the indoor air quality, too. Here are three common causes of airflow issues in your HVAC system and what you should do about them:

Dirty Air Filter

Clogged air filters significantly lower airflow from your HVAC system. The pores of the air filter trap dust, dirt and other debris. Once those pores are full, the air can’t pass through the filter. Dirty filters cause your HVAC system to work harder, and your electricity bills will increase. Replacing a dirty air filter with a clean one every one to three months restores airflow and lowers your HVAC system’s energy use by 15 percent.

Duct Problems

Low airflow could be related to duct damage. A small hole or crack in a duct allows some of the cooled or heated air to leak into your crawlspace or the void between walls. This reduces the flow of cooled or heated air into your living spaces.

Gaps between duct sections and broken seals between the duct and vent also let the air leak before it reaches your rooms. Dust or dirt in the duct impedes airflow, too.

Air Handler Issues

The air handler blows the cooled air from your HVAC system into the ducts. A problem with the air handler’s motor or fan could hinder airflow. A dirty coil, loose wire or sensor issue could result in reduced airflow. These require professional HVAC repairs.
