To replace your AC filter, turn off the unit, locate and remove the old filter, insert a new one in the correct direction, and restart the system. This simple task improves airflow, lowers energy bills, and protects your HVAC from unnecessary wear.
Many Coachella Valley homeowners forget to change their AC filters until airflow weakens or energy bills spike. Dirty filters lead to poor indoor air quality, higher cooling costs, and long-term system damage.
In this guide, you’ll learn when and how to replace your filter safely, what type of filter works best for your home, the risks of neglecting filter changes, and the benefits of routine maintenance.

Steps To Change Your AC Filter Safely
- Turn off the AC unit: Turn off the air conditioning system to ensure your safety and prevent any potential damage.
- Locate the air filter: The air filter is located near the return air duct or inside the air handler unit. It may be in a slot on the wall, ceiling, or within the HVAC system itself.
- Determine the correct filter size: Check the dimensions of your current filter or consult the owner’s manual to determine the correct size and type of filter needed for your AC unit. Filters come in various sizes and ratings, so make sure to get the correct one.
- Remove the old filter: Carefully slide out the old filter from its slot. Take note of how the filter was positioned, making a mental note of the airflow direction, which is usually indicated by arrows on the filter frame.
- Clean the filter slot (optional): If you notice any dirt or debris accumulated around the filter slot, clean it with a soft brush or vacuum cleaner attachment.
- Insert the new filter: Take the new filter and align it correctly with the arrows or indicators on the frame. Make sure it matches the airflow direction you noted earlier. Slide the filter into the slot until it fits firmly.
- Secure the filter: If your AC unit has a filter cover or door, make sure to close and latch it securely. This helps to maintain proper airflow and prevent the filter from being dislodged.
- Turn on the AC unit: Turn on the air conditioning system once the new filter is in place and the filter cover is secured. Check that the system is running properly and that the new filter is correctly installed.
- Schedule regular maintenance: It’s recommended to change your AC filter every one to three months, depending on filter type, indoor air quality, and usage. Regularly inspect and replace the filter as needed to maintain optimal performance and air quality.
How Often Should the AC Air Filter Be Changed?
We recommend changing the air filter every three months. However, you can increase the frequency depending on the type of air filter you have, your household conditions, and how often your HVAC system runs. Homes with pets, smokers, or allergy sufferers may need to change filters every 30 to 60 days for best performance.
Consequences of Neglecting Your AC Filter
A neglected filter strains the system and reduces efficiency – an avoidable expense. Skipping filter changes can make both your comfort and finances more challenging. From poor cooling performance to increased wear on mechanical parts, the problems can be resolved easily by a filter change. In fact, a simple change can save up to 15% on energy bills.
Effects on Blower Fans and Ductwork
When filters are clogged, dust and dirt accumulate inside the system, blocking airflow. This buildup clogs fan motors and valves, forcing your system to work harder. Similar to breathing through a thick cloth. Over time, this leads to premature failure of critical components.
Moisture Accumulation and Mold Risk
Dust and moisture trapped in the system can create a breeding ground for mold and allergens. As your AC circulates air, it can spread mold spores, pollen, and pet dander throughout your home. This worsens indoor air quality and triggers allergies.
Increased Wear and Tear
The more your system struggles to breathe through a clogged filter, the harder it has to work. This leads to inefficient energy use and shortens the lifespan of your unit. Neglected filters often result in expensive repairs – or full system replacement – years ahead of schedule.
What Type of AC Air Filter Should I Use?
With several types of air filters available on the market, it can be challenging to determine which one is best for your AC system. The most important thing to consider is the size of the filter and the specific needs of your HVAC system. The general environmental conditions of your area also help decide the best type of air filter to use.
Below are some of the most common types of air filters, especially recommended for Coachella homes:
Pleated Air Filters
Pleated air filters are a good choice for homeowners wanting a high level of filtration. They are also a good choice for people with allergies, as they remove a wide range of allergens from the air. However, pleated air filters need to be changed more frequently than other filters, so they may not be ideal for everyone.
HEPA Filters
HEPA filters remove tiny particles from the air, making them an excellent choice for people with allergies or asthma. They remove up to 99.97% of air pollutants. However, HEPA filters can be more expensive than other types of filters and may need to be replaced more frequently.
Activated Carbon Filters
Activated carbon filters remove odors and chemicals from the air. They are a good choice for people concerned about indoor air quality. As with HEPA filters, these need to be replaced more frequently and are much more expensive.
Fiberglass Filters
Fiberglass filters are a good choice for homeowners who want a low level of filtration. They are also a good choice for people without allergies or asthma. However, fiberglass filters can be more challenging to clean than other filters and may need to be replaced more frequently.
Benefits of Replacing the Air Filter
New filters provide clean indoor air. The air coming from the vents contains all types of dirt and dust that affect indoor air quality (IAQ). Changing air filters regularly keeps the air safe to breathe, especially for people with asthma, allergies, and other respiratory problems.
Additionally, a dirty air filter restricts airflow. This causes your AC to work harder and leads to higher energy bills. It also leads to ice buildup on the coils, reducing efficiency.
Replacing the air filter on schedule helps:
- Maintain steady airflow and even cooling
- Lower strain on system components
- Reduce the risk of breakdowns and costly repairs
- Extend the lifespan of your HVAC system
Protect Your System with Regular AC Filter Changes
Changing your AC filter keeps your system efficient and your indoor air clean. A clogged filter strains the unit, raises energy costs, and increases the risk of moisture buildup, mold, and system damage. Regular filter replacement helps avoid expensive repairs, extends your AC’s lifespan, and supports healthier air, especially important for homes with allergies or asthma.
At Anthem, we make it easy to stay on top of routine AC maintenance.
