How to Change Your Commercial Air Filters

Dirty filters are the number one cause of avoidable HVAC problems in commercial buildings. They restrict airflow, drive up energy costs, and shorten equipment life. The good news is that routine filter changes are something most facility teams can handle in-house.

Start by identifying the filter size and type for each unit — commercial systems often use multiple filters of different dimensions. Keep a stocked inventory so you are never scrambling. Always power down the unit before opening the filter access panel.

Note the airflow direction arrow printed on the filter frame and install the new filter facing the same way. A backwards filter dramatically reduces efficiency. Log the date so you can track replacement intervals.

High-traffic facilities may need monthly changes, while others can stretch to quarterly. If you are unsure of the right cadence for your building, we can set up a schedule as part of a maintenance plan.
