Every HVAC unit needs filters to trap and filter harmful particles from the air and keep the indoor air healthy. Over time, the air filters in your home will become dirty and will require replacement otherwise they will become clogged and can damage your system. So, we will recommend you change your air filters every two to three months. Make sure you regularly check the air filters, and if required, change your HVAC air filters every month during summer and winter when the unit is used the most.
