Can You Run an AC with a Dirty Filter?

Learn how a dirty air conditioner filter can wreak havoc on your HVAC system and lead to costly repairs or a complete breakdown when you need your AC most.

Can You Run an AC with a Dirty Filter?

An overheated air conditioner can be a sign that the AC filter is clogged. When the filter is dirty, the air conditioning unit has to work harder to keep the room cool, putting more pressure on the system and causing it to produce a lot of heat. Not only will a dirty air filter make the air conditioner inefficient and improperly functioning, it can also damage your oven. It's important to remember that a blocked air filter is the main cause of equipment failure. The overworked blower can fail completely, leading to a costly repair or replacement of the entire HVAC system.

If the filter is heavily soiled, you may feel warm air coming out from the back of the unit. A clogged filter forces the air conditioner to work harder than usual to keep the house cool. This will lead to more frequent repairs and reduce the life of the unit. To reduce this load, it's important to change the AC filter regularly.

A dirty filter makes it difficult for the HVAC unit to draw in air, causing it to work harder than normal and consume more energy. This can lead to an early breakdown. The air conditioner evaporator coils absorb heat from the house as air blows over them. If the air filter becomes clogged, it can slow down airflow and leave the refrigerant in the evaporator coils colder than usual. This can cause the coils to freeze and shut down the system. It's extremely inefficient for your system to turn on and off when coils freeze and thaw.

To avoid this problem, make sure you have a fresh air filter. If your air conditioner's filter becomes clogged during summer cooling season, cold air buildup can cause icing on the AC coils or evaporator. To clean a reusable air filter, simply remove it from your oven and rinse it in warm water. There are many ways to keep your air conditioner well cared for and running efficiently for longer. If you notice that your AC doesn't cool down as it normally does or blows hot air, check if the filter is clogged. Dirty filters make your air conditioner run at a lower efficiency, which means it doesn't cool your home as well as it should and can end up costing you more money in the long run.

If your AC continues to work, licensed technicians can take a look at your filter and clean or replace it if necessary. Although clogged filters are one of the most common problems affecting an AC's functionality, they are often overlooked and need attention most. If you leave a clogged filter for too long, you may experience a system-wide failure. To keep your HVAC system running efficiently for longer, make sure you clean or replace your air filter regularly. Doing so will prevent costly repairs or a complete breakdown when you need your AC most.
