HVAC filters are meant to keep the air clean. However, in some cases, the contaminants inside the filters can clog them. These substances include dust, mold spores, viruses, and bacteria. The debris in the filter can form an impenetrable barrier and cause multiple problems with the HVAC system. In these cases, the best solution is to change the filter. A common mistake is to ignore it, thinking that it will still work properly.
The best way to determine when it’s time to replace your air filter is to look at it closely. Look at the material of the filter, which should be visible through the dirt. A thick layer of dirt will obscure the material of the filter, which means that it’s time to replace it. A dirty air filter will mean that it’s been sitting in the same spot for a long time. When this happens, it’s probably time to replace the filter.
Another important factor in determining how often to change the air filter is the seasons. During the milder seasons, HVAC units won’t need to run as frequently. During these times, the filter won’t become dirty as quickly, which means that it will last longer. Conversely, during heating and cooling seasons, your HVAC system will work much harder to pump air into your home. So, changing the filter will help you keep the air quality in your home at a good level all year round.
