The Impact of a Clogged Cabin Filter on Your AC System

Believe it or not, the cabin filter can have a significant effect on your air conditioning system and, in turn, the power of your entire vehicle. When the filter is clogged, you may need to turn on the air conditioner more often. The harder your air conditioner works, the more the engine will run. This can lead to a variety of issues, such as feeling too hot or too cold. If you own a vehicle manufactured in the last decade, your on-board computer will try to compensate for the lack of an air filter by altering the power supplied to the fans.

However, this can reduce the lifespan of the entire climate control system. Your car was built to last longer with all its components in place, including the cabin air filter. If the air conditioner is used long enough without a cabin filter, the fan will clog with dirt and dust much faster. This can cause problems related to low airflow, such as lack of cooling, a frozen evaporator, and a frozen expansion valve. A cabin air filter whose pores are blocked can cause a strain on the air conditioning system.

In addition to increasing energy consumption, voltage can cause motor damage due to overloads. The cabin air filter has nothing to do with the operation of the vehicle itself. Rather, it works to improve indoor air quality by filtering pollutants. If the cabin filter is clogged, it can reduce the air flow of the air conditioner and make the cabin feel warmer. The air conditioner has to work harder as a result of reduced airflow.

This puts a strain on the system that can eventually cause the fan motor to fail completely. A faulty filter can mean inadequate cabin air, affect air quality, and cause the AC system to consume more energy, among other effects. One of the first and surest signs that a cabin air filter needs to be replaced is reduced airflow in the ventilation grilles. However, the cabin filter also restricts the flow of air through the condenser and the heating coil into the passenger compartment. Simply changing the cabin air filter will dramatically improve your vehicle's air quality. Of all the many parts of the car that work together to make your vehicle work, the cabin air filter may be one of the most mysterious and least understood components.

But what about hazards that can't be seen and effects that are only noticed gradually or during certain modes of operation?The reality is that a foul-smelling cab isn't the most pressing problem drivers will face if they never change their cabin air filter or don't change it often enough. If you don't change your cabin air filter regularly, it will become more clogged with dirt and debris and this will reduce efficiency in your car's filter and HVAC system. Many brands today sell cabin air filters with the idea that no one wants to spend time in a smelly car if they can help it. With a clogged cabin air filter, lack of airflow can be felt in dashboard grilles and this will result in lackluster defrost and defrost performance as well as reduced air conditioning and heating functionality. Unfortunately, many people do not follow this recommendation and neglect their cabin air filters for much longer than they should. This is likely because they do not understand all of the real dangers associated with not changing their filters regularly, partly because of how these filters have been marketed. In extreme cases, a clogged filter can completely obstruct airflow either by causing fan motor failure or by sucking out all of its debris along with it.

To avoid these issues and ensure your car runs smoothly for years to come, it is important to learn more about quality cabin air filters and replace them regularly. Find out more about quality cabin air filters, find your car part or find where to buy your auto part today.
