Regular maintenance such as the replacement of air filters is necessary for HVAC systems.

⚙For the best preventive maintenance, your air filter should be replaced regularly to prolong the life of your HVAC system.

The following signs show if your air filters need to be changed:

🍃 - A reduction in air movement:

This is a sign that your air filter may be clogged and may need to be replaced. Airflow is very important for good indoor air quality.

Pressure drop: Two factors need to be taken into account:

a) If the system permits, filters can be run at the maximum pressure drop specified by the manufacturer for constant speed fans, but you will not benefit from energy savings.

b) If energy savings are possible using a VFD-controlled fan (variable frequency drive), filters should be replaced at twice the initial pressure drop at the same air flow speed during installation.

In normal installations, all filters should be checked every three months if pressure gauges are not available. When using pressure gauges, replacements should be based on the average life achieved with the first few change-outs. Visual inspection should be done quarterly at a minimum.

-Filters are deformed, collapsing, or ripping:

If you notice any of these conditions in normal installations, your filter has likely exceeded its life and must be replaced.
