The Consequences of Running an Air Conditioner Without a Filter

Learn about what happens when you leave your AC without a filter: poor indoor air quality, water damage & health problems.

The Consequences of Running an Air Conditioner Without a Filter

Since air filters are designed to trap dirt, dust, hair, and other contaminants, running the air conditioner without a filter will cause these particles to be recirculated throughout the house. This can lead to poor indoor air quality and can aggravate allergies or affect your health and that of your family. The longer you leave your air conditioner running without a filter, the more likely you are to experience an increase in allergy symptoms, respiratory problems, eye irritation, or nose and throat irritation. Another issue caused by operating the air conditioner without a filter is water damage.

The lack of a filter to capture debris causes the condensate drain to become blocked. In addition, the lack of filters in the air conditioner can cause health problems, such as asthma and allergies, caused by dirt, dust or debris particles. After all, running the air conditioner for more than a day without a filter could affect the system enough to warrant immediate repair of the air conditioner. The air filter is located in front of the air conditioner's return vent (the vent that draws air into the system). While some homeowners can clean or replace their air conditioning filters on their own, it is best to let a professional do the work for you.

By trapping these particles inside your fibers, the filter keeps them away from the air conditioning system, helping to protect your family and your air conditioning equipment. When you run the air conditioner without an air filter in place, the air conditioner draws in “dirty air” and circulates it back to your home. Common air conditioning problems include rising electricity bills, inefficient cooling of the house, or even complete failure of cooling. One way to prevent these issues is to keep the air filter clean and always make sure it's in place before putting the system into operation. This is perhaps a little more obvious, but without the air filter to filter dust, the air conditioner will now shed dust all over the house.

That said, running your air conditioner without a filter for more than 6 to 8 hours can cause serious damage to the air conditioning system and significantly reduce your home's air quality. You can choose to change the filter later at night or on a day when local stores that sell filters aren't open. The air conditioner draws air from your house, strips it of heat and returns it to your house. The freezing winter days or the hot summer seasons will also be unbearable if you run the air conditioner without a filter. Next, let's look at how an AC filter works and what negative effects can occur when running an AC without one. The primary purpose of an AC filter is to trap dirt, dust, hair and other contaminants before they enter your home's ventilation system.

This helps maintain good indoor air quality and prevents these particles from being recirculated throughout your home. Without an AC filter in place, these particles will be drawn into your AC unit and circulated back into your home. In addition to poor indoor air quality, running an AC without a filter can cause water damage due to clogged condensate drains. This is because debris will accumulate in these drains and prevent them from draining properly. Furthermore, running an AC without a filter can cause health problems such as asthma and allergies due to dirt and dust particles being circulated throughout your home. Finally, running an AC without a filter can cause serious damage to your AC unit itself.

This is because debris will accumulate on vital components such as coils and fans which can lead to decreased efficiency or even complete failure of these components. Therefore it is important to always make sure that you have an AC filter in place before turning on your AC unit.
