What Happens When You Don't Change The AC Filter?

When was the last time you checked or changed your AC filter? If you have to think about it, it's probably been too long. Keeping your HVAC system running optimally isn't just about regular check-ups. Something as simple as changing the AC filter can significantly impact its efficiency and longevity.

In our busy lives, maintaining our AC systems can easily be overlooked. However, the consequences of neglecting simple maintenance tasks like changing your AC filter can lead to costly repairs and uncomfortable living conditions. This blog post aims to provide an understanding of the air filter's function, signs indicating the need for replacement, and the repercussions of not changing the AC filter regularly.

What is an Air Filter & How Does it Work?

Air filters play a crucial role in maintaining the air quality within your home and the efficiency of your HVAC system. Essentially, these filters trap and hold various airborne particles such as dust, pollen, mold spores, and other contaminants that could harm your HVAC system and your health. Clean filters ensure your AC system can operate efficiently and maintain better indoor air quality.

How Often Should You Change The AC Filter?

On average, for homes without pets or individuals with allergies, it is recommended to replace your HVAC filter every 90 days. However, this can vary based on several factors, including the size of your home, the filter type, and the dust in your surroundings. If you have pets or someone in the household has allergies, changing the filter every 30-60 days may be advisable.

5 Things That Happen When You Don't Change Your Air Filter

1. Decreased Efficiency: A clogged air filter makes your AC unit work harder to cool your home, decreasing its overall efficiency.
2. Increased Energy Bills: When your AC has to work harder due to a dirty filter, it consumes more energy, leading to higher utility bills.
3. Poor Indoor Air Quality: A dirty filter cannot effectively remove airborne particles, compromising indoor air quality and potentially triggering allergies and respiratory issues.
4. Wear and Tear: The additional strain on the AC unit can lead to faster wear and tear and potentially costly repairs down the line.
5. Shortened Lifespan of the Unit: Regular maintenance, including timely filter changes, is essential for the longevity of your HVAC system. Neglect can result in a shortened lifespan.

Top Signs That Your HVAC Filter Needs Replacement

• Warm air coming out of the unit could indicate that the airflow is restricted due to a dirty filter.
• Unit is not cooling the home: If your AC is running, but your home isn't cooling down, it might be due to a clogged filter.
• High energy bills: A significant increase in your energy bill could mean your HVAC system is working harder due to a dirty filter.
• Physical signs of dust: If you notice more dust around your home, it might be time to check your filter.
• Allergies: A rise in allergy symptoms could indicate that your filter is not effectively removing allergens from the air.

What Happens if You Don’t Change HVAC Filters?

1. Furnace Damage: A dirty air filter can cause the heat exchanger to overheat and shut off too quickly, leading to potential damage and reduced comfort.
2. Evaporator Coils Damage: The dirt from a clogged filter can find its way to the evaporator coils, causing them to frost over and potentially lead to more serious issues.
3. Regular Breakdown: A dirty filter can cause various HVAC system components to work harder and increase the likelihood of regular breakdowns.

Do You Need To Call A Technician for An HVAC Filter Change?

While changing an air filter is a task most homeowners can do themselves, many may prefer to have a professional handle it. This can be beneficial as HVAC technicians can inspect and identify potential issues before they become costly.
