Why Summer Is the Toughest Season for Your Air Conditioner

As the temperature outside starts to rise, it is almost impossible to get through the day with constant functioning of the cooling systems such as fans and air conditioners in the background. They are running a lot longer and more frequently making summer the most demanding season for it. Unlike other seasons like spring or fall, wherein air conditioners don't need to be used  round the clock, summers require continuous operations even if the day is moderately hot.

Thanks to this constant and non-stop functioning, air conditioners are subject to increased workload, additional strain on all the essential components such as the compressor, the coils, the motor and the most important component being the air conditioner filter. What makes this strain worse is unnoticed maintenance issues that are overlooked over a long period of time especially during cooler months when the air conditioner isn't used that often. All these factors can quickly take a toll on the systems, for example, a dirty air conditioner filter can reduce the overall cooling performance when the airflow gets restricted and the unit is forced to work overtime and twice as hard to circulate the same amount of cool air throughout the day and during peak summers, it needs to function even throughout the night which means its working round the clock.

This will automatically lead to higher electricity bills from AC, longer unexpected cooling cycles, uneven temperatures during the day and night, and increased wear on  the system’s other essential components.

For these reasons, summer air conditioner maintenance should be a big priority for most homeowners. By following a regular and routine AC maintenance checklist and carrying out the essential routine tasks such as air conditioner filter cleaning, coil inspection, and regular airflow checks, one can ensure  efficiency is steady and stable. This will also help maintain comfort indoors and reduce the chance of an unexpected breakdown during peak cooling season which is summer.

Why Cleaning Your Air Conditioner Filter Matters

While the air conditioner isn’t a small device, the filters are and they play a significant role in ensuring the device continues to perform well. The primary job of these filters is to capture external particles like dust, pollen, pet dander and other particles that could be airborne. It prevents these from entering the system and circulating everywhere. If this important process is ignored and neglected, the external particles will collect and accumulate on the filter, restricting the airflow and forcing the unit to work twice as harder than usual to maintain the desired normal room temperature throughout the day.

Regular maintenance starts with cleaning the filter. Let’s take a look at the noticeable impact it has on the filters and the air conditioners’ overall cooling performance. 

Improves Overall Air Conditioner Efficiency

One of the biggest reasons why cleaning the filter matters the most is because it  improves the overall quality of the airflow.  Clean airflow is very important and for this a clean filter is needed. It allows the air to move more freely through the system and this will help cool the home throughout the day and night. If this is not looked into, the airflow gets restricted and the unit is under pressure to deliver the same results.

Reduces Unnecessary Energy Consumption

A dirty or clogged up filter can impact your overall energy usage. For example, if it hasn't been cleaned for a really long time, the air conditioner will run for a longer period of time to generate the cooling the space needs. This is a heavy obstruction on its overall functioning as it leads to heavy energy consumption. Regular cleaning and maintenance is one of the easiest ways to reduce energy consumption and for homeowners who are looking for ways to reduce overall cooling costs during the summer, routine cleaning offers one of the best and highest returns with the least amount of effort being involved.

Improves Indoor Air Quality

The condition and the current state of your air conditioner  has a profound effect on the air you breathe. So to ensure you are breathing clean air everyday, your filter needs to be clean. A clean filter helps to trap allergens, dust especially in households with furry pets, young kids, or with individuals who suffer from dust allergies and respirator issues. Cleaning the air filter helps to create a healthier living environment.

Longer Lifespan

When operating systems like an air conditioner are constantly functioning and operating in work mode, the wear and tear of it becomes vulnerable and exposed to damage. Without regular maintenance and cleaning, the overall lifespan of the system gets cut short and  while it's still working, you will have to deal with reduced cooling performance and frequent repair work. Cleaning the system from time to time, reduces the unnecessary stress on the equipment and supports long-term reliability which increases the overall lifespan.

Consistent Cooling Performance

When the filter in an air conditioner is kept clean, it eliminates hot spots, maintains temperature consistency and allows the system to maintain its performance especially during  extreme summer heat periods. Hence, regular filter cleaning is one of the simplest  yet effective ways to keep your  air conditioner operating efficiently.

Major Signs Your Air Conditioner Filter Needs Regular Cleaning

The air conditioner not cooling properly or when your air conditioner filter gets clogged with various forms of external particles, it becomes difficult for it to generate the regular cooling performance and ultimately, it forces the system to work harder than normal. Recognizing these early signs and dirty air conditioner filter symptoms that affect your device can help  you prevent major maintenance expenses.

Weak Airflow:

One of the most common signs to look out for is weak airflow from the vents. When you start to notice weak or low airflow , that's the first and foremost warning  that your system is dealing with restricted airflow and is unable to distribute cool air evenly throughout the space.

Dust Accumulation:

When you pay close attention and start to notice excessive dust  that’s collected around the vents, on the furniture, or even on the floors, that’s your sign that the filter is no longer trapping airborne particles properly. This can easily contribute to poor indoor air being circulated indoors and will also reduce the quality of it.

Longer Cooling Cycles:

If your air conditioner is not cooling normally  wherein it seems to be taking longer than usual or running continuously, the filter may be clogged. This is because longer cooling cycles increase the wear on the system and reduce its cooling efficiency.

Higher Energy Bills:

This is the result of the above signs and it's also a sign in itself. A dirty filter tends to force the air conditioner to run longer for a longer period of time  to maintain the desired temperature, which  generates higher electricity bills due to increased energy consumption.This is unavoidable if the device is running nonstop.

Thus, regular air conditioner maintenance is non-negiotable and timely filter cleaning helps to maintain cooling performance during the summer while simultaneously reducing the unnecessary strain on the system. If you notice any of the warning signs above, the next  critical step is to clean the air conditioner filter before the overall system performance is completely affected.

How to Clean an Air Conditioner Filter Step by Step

If you notice weak airflow, rising energy bills, or longer cooling cycles, cleaning the air conditioner filter should be one of the first maintenance steps to take. Fortunately, this is a simple DIY air conditioner filter cleaning task that most homeowners can complete in just a few minutes. So here’s how to clean air conditioner filter, step by step:

Step 1: Turn Off Your Device

Before you embark on cleaning or doing any work, make sure you switch off the air conditioner and disconnect the power supply if that's a possible option. This way, you are taking safety precaution steps to help prevent any room for accidental operation during cleaning.

Step 2: Remove the Filter

First and foremost, you need to locate the air conditioner filter, this is usually found behind the front grille, inside the return vent, and in some cases, it is found near the air intake section. Once you have found it, carefully remove the filter from the device and inspect it properly for dust buildup and debris.

Step 3: Vacuum Loose Dust and Dirt

To remove any form of loose dust from both sides of the filter , you need to use a good vacuum cleaner or soft brush if available. This step will help make the washing process a lot more effective.

Step 4: Wash the Filter

For washing the filter, you need to rinse the filter properly and carefully with room temperature or lukewarm water. If needed, use a mild soap to remove any form of stubborn dirt. Avoid using strong chemicals or high-pressure water, as they can damage the filter material.

Step 5: Allow the Filter to Dry Completely

Once the cleaning and washing steps are done, keep the filter in a shaded, well-ventilated area and allow it to dry completely before reinstalling it back into the device. Reinstalling a damp filter can sometimes lead to mold growth inside the system and will also lead to poor indoor air quality.

Step 6: Reinstall the Filter

Once it's completely dry, you can place the clean reusable air filter back into the device and secure all the covers and panels. Then, you can turn the system back on and inspect it for improved airflow and check its cooling performance.

Following these simple yet effective steps will give you a routine for air conditioner maintenance and it will significantly help improve  the overall air conditioner efficiency, help maintain indoor comfort, and reduce the cooling costs during  peak summer.
