Understanding the Major Impact of a Dirty AC Filter

Do air conditioning units have filters? The answer is yes, and these filters are vital to the basic operations of your AC and HVAC system. In particular, dirty AC filters that are not changed or cleaned regularly can have several negative effects that should be avoided.

At Thompson’s Comfort Connection, we’re happy to offer a huge range of air conditioning installation, AC repair and related services for clients around Sandy, Midvale, Cottonwood Heights, Draper, Riverton and nearby areas. Here’s a primer on the basic but vital roles that air filters play in your AC and HVAC system throughout the year, plus the key risks of dirty filters and why you should always stay on top of periodic changes.

Roles Played by HVAC Air Filters

Firstly, what are the main roles played by air conditioning filters within your home’s HVAC system? Here are the primary functions:

• Air quality: The most well-known function of AC filters is to help keep clean, fresh air circulating throughout your home. These filters trap dust, pollen, pet dander, and other particles that can cause allergies or aggravate respiratory conditions.
• System protection: Another key role of AC filters is to protect your HVAC system from damage caused by debris and contaminants. Without a filter, these particles can clog up various components and reduce the efficiency of your system over time.
• Energy efficiency: By trapping particles and keeping them from circulating in your home, AC filters also contribute to energy efficiency. When your system doesn’t have to work as hard to control air quality, it uses less energy and can save you money on utility bills.

Now that we’ve discussed the roles played by AC filters, let’s dive into the risks of not changing or cleaning them regularly. Some common issues caused by dirty filters include both system and personal concerns.

Dirty Air and Health Issues

Some of the most notable risks of not changing your AC filters include:

• Allergies: If you or anyone in your household suffers from allergies, dirty filters can exacerbate symptoms. As mentioned earlier, these filters trap allergens and prevent them from circulating in the air. When they are dirty and clogged, these particles have a higher chance of sneaking through.
• Respiratory issues: Along with allergies, dirty filters can also aggravate respiratory conditions such as asthma or bronchitis. This is because the trapped particles can irritate the airways and cause breathing difficulties.
• Stagnant air: When filters are dirty, they can restrict airflow and cause air to become stagnant. This can lead to a musty or stale smell in your home and can make it uncomfortable to live in.

System Problems Caused by Dirty Filters

In addition to health concerns, not changing AC filters regularly can also have negative effects on your HVAC system itself:

• Reduced efficiency: As mentioned earlier, clogged filters can reduce the efficiency of your system. This means that it will have to work harder and use more energy to maintain the desired temperature in your home.
• Frozen coils: When air cannot flow freely through the filter, it can cause the evaporator coils in your system to freeze. This restricts cooling and can eventually lead to a breakdown.
• Overheating: Similarly, dirty filters can also cause the system’s motor to overheat due to restricted airflow. This can result in damage and costly repairs.

Comfort Issues Caused by Dirty Filters

On top of health and system concerns, dirty filters can also affect your overall comfort at home:

• Uneven temperatures: When airflow is restricted due to dirty filters, some areas of your home may be colder or warmer than others. This can create an uncomfortable living environment and lead to disagreements among household members.
• Increased humidity: Dirty filters can also contribute to higher levels of humidity in your home. This not only makes the air feel heavier and more uncomfortable but also promotes the growth of mold and mildew.
• Noisy operation: A clogged filter can cause your HVAC system to make loud noises as it struggles to function properly. This can be disruptive and annoying for you and your family.

Knowing Filter Changing or Cleaning Frequency

Depending on the type of filter you use and your home’s air quality, the frequency at which you should change or clean your AC filters may vary. It’s best to consult with a professional HVAC technician who can assess your specific needs and make recommendations. As a general rule, it’s recommended to change or clean your filters every 1-3 months.

Air conditioning units do indeed have filters that play crucial roles in maintaining air quality, protecting the system, and promoting energy efficiency. Neglecting regular changes or cleaning of these filters can lead to various issues, including health concerns, system problems, and discomfort. Be sure to stay on top of periodic filter changes to keep your AC functioning properly and efficiently.
