If you fail to check and change the air filter regularly, it can lead to environmental problems. A dirty air filter means a straining HVAC system, something that uses more energy. That can lead to increased emission of carbon monoxide or greenhouse gases. A simple thing like changing an air filter when it’s necessary can go a long way toward reducing your carbon footprint.


Basically, you should change the air filter every 1 to 3 months depending on how heavily you are using the HVAC system and how quickly the filters are being clogged. This way, the filter – and the entire HVAC system – functions properly and efficiently.
