Keeping the air filter of your heating, ventilation and air conditioning unit clean is an important maintenance task that can be done by a homeowner. Dirty air filters are the primary reason that HVAC systems stop working. Filters prevent airborne particulates from entering the HVAC equipment and your living space. Cleaning the filter improves performance and saves energy.
Locating the Filter
Usually, filters are located in the return air duct. They may also be located in the furnace housing or air handler. Before removing the filter, turn off the power to the unit. Remove the filter and inspect it. Some can be cleaned and reused. Others must be replaced.
Replacing the Filter
Filters should be replaced or cleaned at least every three months. If you use your HVAC system continuously, live in an area with a lot of dust or have pets, change the filter more frequently. Once the filter is out, clean around the exposed area. If your filter is washable, follow the instructions printed on the side of the filter. Write the date of cleaning or replacement on the filter. Insert it into the space, making sure that the correct side faces the upstream flow of air.
Benefits of HVAC Air Filters
Standard HVAC filters are designed to keep particulates from entering the system, which helps keep coils, ducts and other components clean. If you would like to upgrade to a high-efficiency filter to improve indoor air quality, speak to your HVAC contractor. The contractor will know what types of air filters will work with your system. In addition, there are other accessories that work with HVAC systems that also improve the quality of your indoor air.
