Some say you can run your AC system without a filter. While that is true, there are several reason why you should not give it a try. A clean filter is an essential part that ensures that your system runs properly. Below find a list of problems that will occur if you decide to run your unit without a filter:
A clean filer protects your system from dirt. Without a clean filter, dirt will get into the blower motor and the evaporator coils. If dirt gets into those parts of your system, it is more likely to breakdown.
If you want to prevent debris from collecting in your condensate drain, you will need a clean filter. Debris collecting in the condensate drain will clog up the drain and lead to water damage to your system. Fixing that can get very expensive.
Without a filter, dust in your home is sucked through the intake and then gets pumped back through your air vents. This means dirt, dust and debris will be constantly circulated through your living spaces until you and your family breathe it in or it clogs and breaks your unit.
The Freon tubes, the lines that carry the refrigerant between the evaporator and condenser coils, in your AC system are always wet. Without an air filter, dirty or dusty air gets blown over those tubes, then debris will stick to the condensate and coat the fins. When this happens, your system will operate inefficiently.
Without a filter debris, dust will start collecting in your ducts. When that happens, moisture will start to build up inside your ductwork, creating the perfect place for mold to grow.
