What Are the Consequences of Running an Air Conditioner Without a Filter?
Running AC without filter can have some pretty serious consequences. Before we talk about the damage to the HVAC system itself, let’s discuss the more serious health impacts that running your AC without a filter could have. AC filters are designed to trap dirt, allergens, dust, and other debris including bacteria.
Running your AC without a filter will, undoubtedly, result in more of those pathogens and debri floating around in the air your family breathes. This can result in respiratory irritation, allergies, and other health issues. In addition to health concerns related to running your AC without a filter, the same dirt, dust, and debri can clog up crucial elements to your HVAC system. Over time, this accumulation can end up costing you a good amount of money to fix.
Can Running an Air Conditioner Without a Filter Cause Mechanical Damage?
To further elaborate on the type of damage that running an air conditioner without a filter could cause, let’s break it down into parts.
-
Ductwork: Accumulation of particles in the ductwork itself could prevent air from flowing freely. This causes stress on the system, reduced functionality, and poor air quality in your home.
-
Condensation drain: The condensation drain functions to remove excess moisture in the dehumidifying process. When this becomes clogged, it could result in water damage to your system and home.
-
Freon tube: When debri covers the tubes that hold the cooling agent Freon, those tubes are prevented from cooling properly.
How Does the Absence of a Filter Impact Indoor Air Quality?
When there is no filter to catch pet dander, pollen, dirt, and other pollutants, those things have nowhere to go but to be blown all over your home. Additionally, accumulation of these irritants in your HVAC system make an ideal breeding ground for mold and bacteria - worsening the quality of air in your home and putting you and your family at risk for respiratory and other health related issues.
Is It Safe to Operate an Air Conditioner Without a Filter Temporarily?
You may be tempted to operate your air conditioner without a filter temporarily, but it is not recommended. It’s much safer for your system and your health to halt operation until you acquire a new air filter.
What Are the Best Practices for Maintaining Air Conditioner Filters?
Your air conditioner filter should be replaced every 30-90 days depending on your AC usage, whether or not you have pets, and the quality of your AC filter. Always use the correct sized filter so that debri does not get past it and into your HVAC system. Regular HVAC system check-ups should be done by a licensed technician to identify any issues that your filter or system may have before they worsen.
Does Operating an Air Conditioner Without a Filter Affect Energy Efficiency?
Yes. To put it simply, when the internal HVAC components are suffering from reduced function due to an accumulation of debri, your system has to work harder. This increased work force means a higher electric bill for you.

Excessive amounts of dirt and dust floating around your home

Strange noises coming from your system
