The air filter for your HVAC system is a critical component for it to operate well. It isn’t there to clean your household air but to protect the interior of the cabinet from all the dust, lint, and other particles the blower fan draws in through the return air ducts.
Just as important as the job of the air filter is changing the filter regularly. The filter isn’t self-cleaning, so it has to be replaced with a new filter to prevent air blockage. Unfortunately, homeowners often forget to do this job, especially during the winter when the HVAC system won’t run as often in the mild Florida weather. But even during winter, regular filter changes are essential.
