You may have been told that it’s important to change the air filter in your HVAC system, but never really understood why. It’s always a good idea to have a basic understanding of why this simple task is so important, since this knowledge might persuade you to take the time and effort to inspect and change your filter more regularly.
Why Air Filters Should Be Changed
Simply speaking, if your filter gets clogged, it can’t properly do its job. There are several negative consequences of not changing your HVAC air filters, some of which include:
Reduced efficiency. As your air filter removes airborne dust and debris, it can become clogged with these particulates. When this happens, the fan in your forced-air heating or cooling system has to work harder to force air through the filter. Not only does this waste energy, but it also takes longer to heat or cool your home. Optimum airflow is mandatory for your furnace, A/C or heat pump to operate the way it’s designed to. Additionally sensitive HVAC components coated with dust, dirt or mold – such as the blower motor and A/C coils — can’t operate as smoothly and efficiently.
Shorter lifespan. Equipment that has to work harder than necessary, or with more friction between moving parts, obviously won’t last as long. This means you can expect more frequent breakdowns and a shorter life expectancy for your HVAC equipment.
Dirty air. If you rely on a high-efficiency HVAC filter to help clean indoor air, you’ll be disappointed to learn that a clogged filter will eventually begin letting contaminants blow past the filter and into your ductwork. Mold and bacteria can also coat A/C and heat pump coils. All of these issues can threaten the health of home occupants.
Get in the habit of inspecting your air filters monthly and changing them when they look dirty or clogged. For more information on proper HVAC maintenance, please contact Davis Air Conditioning in Southwest Oklahoma.
