Airflow issues are some of the telltale signs that your HVAC system has a problem. Restricted movement of air causes hot and cold spots in your home and pressure imbalance, which reduces your comfort level and limits the energy efficiency of your HVAC system. Read on to learn four of the causes of poor airflow in your Azusa, CA, home and how you can fix them.

Clogged Air Filters

The air filters in your HVAC system trap dust, dirt and other pollutants, thus preventing them from circulating through your home. Leaving the air filters dirty and failing to replace them regularly will cause clogging, which restricts the flow of air.

To prevent the clogging of the air filters, check them regularly and clean them when needed. We recommend changing the air filters every three months.

Leaking Ductwork

The ductwork in your home delivers cool or warm air to every part of the home. However, the ducts can develop cracks and leaks that cause cool or warm air to escape. These leaks affect the quality and amount of air delivered in your indoor space.

Besides leaks and cracks, pollutants such as dust and pollen can cause buildup in the ductwork, which restricts airflow. We can inspect the ductwork during a preventive maintenance visit to determine whether there are leaks or cracks. However, simply cleaning the ducts can resolve these problems.

Blocked Vents or Registers

Blocked registers or vents can cause restricted flow of air in the home. You need to move any furniture or other items blocking the vents or registers, which should be fully open. We recommend leaving at least 8 to 12 inches of space around the vents and registers to increase airflow.

Reduced Refrigerant Levels

Any refrigerant leak in your HVAC system can reduce the its performance, causing restricted airflow. You can solve this problem by scheduling regular maintenance on your HVAC unit and replacing old and outdated systems.
