When it comes to air conditioning units, air filters are essential components. Without a filter, the condensate drain will not be able to drain moisture from the air conditioning unit, leading to condensation building up in the Freon tube and dripping down the tray. This can cause significant damage to the system, as well as clog parts and restrict airflow. In addition, all the accumulation of dust and dirt can cause the air conditioner to overheat and turn off, potentially leading to permanent damage to your engine.
The price to fix this problem is higher than simply buying a new air filter every few months. That's why it's important to use an air filter and change it frequently. Keep reading to learn more about how air filters work in your HVAC system and what can happen when they aren't changed on a regular basis. Air filters are usually made of spun fiberglass or pleated paper framed with cardboard for added stability and rigidity.
They are designed to accommodate tiny elements, but the buildup creates a nearly impenetrable barrier so that air cannot fully flow, which can ultimately cause multiple problems for the entire HVAC system. If you don't use an air filter in your air conditioning unit, or if you go months without changing the dirt, you will no longer be able to filter the air properly, allowing dust and contaminants to enter the HVAC system. This means that the entire system has to work harder to distribute heat or air where it's needed, increasing your utility bills, as the air works longer. In addition, running your air conditioner without a filter for more than 6 to 8 hours can cause serious damage to your air conditioning system and significantly reduce the air quality in your home.
The long-term effects of not using an air filter could be respiratory disease, heart disease, or cancer. One way to avoid this is to keep the air filter clean and always make sure it is in place before operating the system.
