Air Filters and Your HVAC System: Debunking Three Common Myths

Posted on

The air filter, or filters, as some units have more than one, in your HVAC system play an important role in the function of your heating and cooling unit. Unfortunately though, there are many myths surrounding air filters and HVAC units. People make mistakes when it comes to their air filters because they believe these myths. Learning what these myths are and the truth surrounding these myths can help you avoid making these mistakes. Here are three common myths related to air filters and HVAC systems. 

Air Filters Only Need to Be Replaced One Time a Year

One of the biggest myths out there related to air filters and your HVAC system is that the air filters only need to be replaced one time per year. There are actually many factors that affect how frequently the filters need to be replaced. A filter with a higher MERV rating will need to be replaced more frequently than a filter with a lower MERV rating. A higher MERV rating means the filter can filter out smaller particles. This helps to keep your air cleaner. But it also causes the filter to fill up faster. Also, for those with pets, those who naturally have more dusty homes, and those who live in more country-like settings may need to replace their filter more frequently. An HVAC maintenance service can tell you how often your filter should be replaced based on your situation. 

Nothing Happens if You Don't Change the Air Filter

Another common myth related to HVAC systems and air filters is that nothing will really happen if you do not change the filters in your HVAC unit. If you fail to change the air filter in your unit, the air in your home will become dirtier. This is because the filter is not able to work as it should. In addition to this, less air may be able to enter your HVAC unit to be heated or cooled, because it cannot pass through the dirty filter. As such, your unit has to work harder and longer to heat or cool air. This shortens the lifespan of your unit and increases your energy costs. 

You Can Replace the Air Filter Yourself

The last myth related to HVAC systems and air filters is that you can replace an air filter yourself. Many air filters are located behind other parts in the HVAC unit. As such, you may not be able to access the filter yourself and replace it. Fortunately, HVAC maintenance services can help you, replacing the filter or filters in your unit when needed.
