Clogged and dirty air filters are the single most common cause of HVAC failure. Many homeowners make the problem worse by installing the wrong grade of filter, which can lead to frozen coils and system breakdown.
It’s essential to change your air filter regularly to prevent dust, mold, and other particles from clogging the system and making you sick. But you must do it correctly to avoid damaging your system.
Dirty air filters have to blow harder to get the same amount of air through. This condition means they use more significant amounts of energy, costing you more money in the long run.
Don’t expect dirty air filters to work consistently. If you find that your home is too hot in one room and too cold in another, that could be due to a dirty air filter some-where in the system.
Letting air filters get clogged runs the risk of your HVAC system overheating or freezing. A dirty filter can damage the internal coils, resulting in costly repairs and even installing a completely new system.
Mold is one of the worst things to get stuck in an HVAC system. Since mold is alive, it can spread throughout the system. It is also dangerous for you and your family to breathe in moldy air from your HVAC system. Following the manufacturer’s recommended filter replacement schedule can prevent mold from expanding.
Optimally, you should change your air filter every two months. And, changing a filter is simple- you slide out the old one and slide in the new one. Make sure to identify the airflow direction printed on the filter and insert accordingly.
But you do need to make sure you put in exactly the right filter!
Did you know that there are many different grades of air filters? When upgrading your system, it’s not just the size of the filter that matters. Installing the wrong grade of filter could lead to frozen coils and damage to your HVAC system.
