If you don't change the air conditioning filter, it will start to fail. You will no longer be able to filter the air properly, allowing dust and contaminants to enter the air conditioning system. Dust clogs up moving parts of an air conditioner, such as motors and fan valves. Airflow is restricted, creating tension in the system.
Evaporative coils are responsible for removing heat to keep your home cool. If you don't replace the air filters for a long time, you will eventually experience a failure in the evaporator coils. While the primary function of filters isn't to increase indoor air quality, if they're not changed routinely, pollen and dander are more likely to enter your home or business. Not changing the filter can also cause moisture to build up in the structure, which can lead to bigger problems, such as mold.
If you notice that your energy consumption is unexpectedly higher, your air filters may be clogged. If you don't change your air filters for a while, they become clogged with contaminants. This means that air cannot easily or freely flow through the system. The consequences of not changing your air conditioner filter can be serious and far-reaching.
Not only will it reduce the efficiency of your air conditioner, but it can also lead to health problems due to poor indoor air quality. It can also cause damage to the system itself, leading to costly repairs or even replacement. It's important to remember that changing your air filter regularly is essential for keeping your air conditioner running efficiently and safely. It's recommended that you change your filter every three months or as needed depending on the type of filter you have.
If you're unsure how often you should change your filter, consult with a professional HVAC technician.
