Why Air Filters Are So Important


Air conditioners are an expensive but necessary piece of equipment in our Gainesville area homes. They cost even more to operate if they aren't running at 100% efficiency. As a homeowner it is very important to protect your investment and minimize costs by making sure you keep up on your HVAC maintenance. The first and easiest thing to do is to make sure your air filters get changed regularly.


Keep Filters Clean

Filters can help reduce your air conditioner's energy consumption by as much as 15% if they are kept clean according to the Department of Energy's Energy Savers website. Why do they effect this so much? Consider the nature of an air filter.


All of the air your HVAC unit uses to condition your home is pulled through your system. This includes, dust, debris, sediment and allergens that are being pulled through the air. In order to protect the workings of your system, it was designed to pull the air through a filter so that these bits of debris do not end up clogging the machinery. Not only would this debris effect the workings of the machine itself, it would also reduce your air quality within your home if your machine did not have a filter.


That being said, filters can only do their jobs if they are kept clean. A clogged filter makes an HVAC system work much harder to pull air through which in turn makes the motor turn faster and increases your electricity usage. Filters get clogged easily so it is very important to check your filters at least once every 30 days regardless of what type of filter your system uses.


Which Filters To Check

Most HVAC systems have one main filter that needs to be checked, but some systems may have additional filters installed within the system. If you have any questions about how to change your filters or where they are located, you might consider having a technician check over your system. They can assess the state of your unit and walk you through how to change your filters.


Another thing to consider is the condition of your home and what the area around your condensing unit is like. If you have pets, lots of plants or you have excessive amounts of dust around your condenser, you may need to do regular checks on your filters even more frequently.


Most filters are located along the return length of ductwork. Sometimes this will be in ceiling ducts or walls, but they may also be located in your system's air handler. If you have window units or mini splits, the filters are frequently in the unit.


Clean air filters are important for your health, your wallet and the longevity of your AC system. Stay on top of them and you will save money in more ways than you might expect.
