HVAC systems can be susceptible to a number of problems including reduced airflow. Restricted airflow is a huge problem that can plague your HVAC system, but it isn’t talked about very often. If the airflow through your system is restricted, your equipment can become overheated or stressed. This can force your system to use an extraordinarily high amount of energy, resulting in high utility bills. You also may not be comfortable, as your system may not be heating or cooling your home properly.

Performing some basic HVAC maintenance each month can ensure that the air flow through your system is at maximum capacity. Proper airflow through your system will keep your energy consumption and bills low and will keep you and your family comfortable.

Here’s what you can do to improve your HVAC airflow-

1. Inspect your air filter each month and change it if necessary. Your filter should be changed every 3 months at minimum, but during the summer and winter months when your system is running more, you may need to change your filter more often. When you look at your filter, check to see if its covered in gray material. If its covered in gray, change your filter. The MERV rating of your filter is also important. Using a filter with a MERV rating higher than 13 (such as a HEPA filter) can actually restrict airflow in a residential unit. A filter with a MERV rating between 8 and 12 is ideal for a residential HVAC system.

2. Check all your vents and grills each month. Make sure they aren’t blocked by furniture, rugs or any other household items. Also, make sure all vents and grills are open. If you have multiple areas in your home that you don’t want to heat or cool along with the rest of your home, you may want to consider installing a zoning system. Closing multiple vents and grills can cause air to back up inside the system, which can damage certain components.

3. During the summer, check your exterior condenser to make sure it hasn’t become clogged. Grass clippings can easily blow up against the fins of the unit, which prevents air from moving through it. Summer is also a time when you may see a lot of vegetation growth that can grow up around your unit, restricting your air flow. Also, don’t store outside equipment such as lawn furniture or toys around your outside HVAC system components.
