In this article, we’ll provide detailed instructions on how to clean air conditioner filters, and offer additional maintenance tips to ensure your system operates smoothly. Discover how to keep your air cool and your unit running efficiently now!

Why should you clean air conditioner filter?

Before learning how to clean air conditioner filter, let’s explore why it is essential. Firstly, it significantly improves the air quality in your home. A clean filter effectively traps and removes dust, pollen, and other airborne particles, ensuring cleaner, healthier air circulation. Moreover, it enhances the efficiency of your air conditioner. A clogged filter forces the unit to work harder to circulate air, which can lead to increased energy consumption and higher utility bills. Additionally, regular cleaning helps to extend the life of your air conditioning unit by preventing dust and dirt from building up in the system, which can cause costly malfunctions and breakdowns. 

How do I clean air conditioner filter? 

Keeping your air conditioner filter clean contributes to the efficiency and longevity of your unit. Here's a detailed, logical guide to cleaning your air conditioner filter:

Turn off the unit

Always start by ensuring your safety; switch off your air conditioner. This step prevents the unit from accidentally turning on while you're working, which could lead to injuries or damage to the system.

Remove air conditioner filter

Find the filter, usually located behind the front panel of the unit or in a designated slot along the side, bottom, or top. Slide the filter out carefully, taking care not to damage it if it’s reusable or preparing it for disposal if it’s meant to be replaced.

Vacuum the filter

Use the brush attachment on your vacuum to gently clean the filter. This step is effective for removing loose dust and larger particles and is ideal for filters that aren't excessively dirty.

Wash the filter

If your filter is designed to be washed, hold it under lukewarm running water to rinse away residual dust. For a deeper clean, soak the filter in a basin with warm water and a mild detergent for about 10-15 minutes. Agitate the water gently to release any embedded dirt.

Dry the filter thoroughly

Allow the filter to air dry completely in a well-ventilated area. It’s important to ensure the filter is fully dry to prevent mold or mildew from developing, which can spread through your home when the unit is used.

Reinstall the filter

Once the filter is completely dry, reinsert it into the air conditioner. Make sure it fits securely and that all edges are properly aligned. Replace any covers or panels that were removed during the process.

Turn the unit on

Reactivate your air conditioner. And now you can notice that it runs more smoothly and efficiently with a clean filter.

Other maintenance tips for your air conditioner filter

After knowing how to clean AC filter step by step, we will continue to show some useful tips to maintain your air conditioner filter.

Changing air filters

Replace disposable air filters or upgrade reusable ones as recommended by the manufacturer, typically every 90-180 days. New filters improve airflow and air quality, reducing strain on the air conditioner and lowering energy costs by maintaining optimal air flow.

Clearing debris around the outdoor unit

Keep the area around your air conditioner's outdoor unit clear of leaves, dirt, and other debris. This clearance helps maintain adequate airflow around the condenser coils and prevents overheating. Regularly removing any obstacles can also reduce wear and tear on the unit.

Scheduling professional HVAC inspections

Arrange for an HVAC professional to inspect your air conditioning system annually. These inspections help catch issues before they become major problems, ensuring the system operates at peak efficiency. Professionals can check coolant levels, electrical connections, and overall system health, adjustments that typically require specialized knowledge and tools.

How often to clean air conditioner filter?

The frequency of cleaning your air conditioner filter depends largely on your usage, environment, and specific household needs. As a general guideline, you should inspect and potentially clean your air conditioner filter every month during peak usage seasons, such as summer and winter. If you live in a dustier environment or have pets, you might need to check and clean it more frequently. 

It is worth noting that now most conditioners are smart enough to inform you of filter cleanliness. For example, BreezeIN Air Conditioner featuring filter blockage reminder will show “CL” if the filter is full and send you a reminder via TCL Home app. That means that staying on top of maintenance can be more straightforward and with less guesswork.

Professional service vs. DIY cleaning: Which is best for your air conditioner filter?

Deciding between professional service and DIY cleaning for your air conditioner filter depends on several factors, including your comfort level with maintenance tasks, the complexity of your AC system, and your budget.

DIY Cleaning:

Pros:

• Cost-Effective: DIY cleaning primarily costs you time, not money. There are no service fees, and you only need basic tools.
• Immediate Attention: You can clean the filter as soon as you notice it's dirty, without waiting for a professional.
• Frequent Maintenance: Easy access allows for more regular cleaning, which can maintain efficiency and air quality.

Cons:

• Risk of Damage: Incorrect handling during cleaning can damage the filter or the AC unit.
• Less Thorough: Without the tools and expertise of a professional, you might not clean the filter as deeply or thoroughly.

Professional Service:

Pros:

• Expertise and Efficiency: Professionals have the tools and knowledge to thoroughly clean and inspect the filter and unit, ensuring optimal performance.
• Comprehensive Maintenance: Service often includes checks and maintenance beyond just cleaning the filter, which can prevent future issues.
• Safety: Professionals are trained to handle various AC systems safely, reducing the risk of injury or damage.

Cons:

• Cost: Professional services can be expensive, especially if conducted regularly.
• Scheduling: You must work around the availability of technicians, which may delay service.

Ultimately, if your air conditioner has a simple, easy-to-access filter and you are comfortable with routine tasks, DIY cleaning can be sufficient and cost-effective. However, for complex systems or if you prefer a thorough check-up, professional service is advisable to ensure deep cleaning and to maintain the unit's longevity and efficiency. Regular professional check-ups, perhaps annually, complemented by your own routine cleaning, can be an optimal approach.
