How To Clean Your Air Conditioner Filter (DIY Guide)

As the scorching summer heat rolls in, there’s nothing quite like the cool, refreshing breeze from your trusty air conditioner (AC) to keep you comfortable. However, for your AC to function effectively and efficiently, it’s essential to pay attention to one often overlooked component – the AC filter.

Today, we’ll delve into:

  • What an AC filter is
  • Why it’s crucial to keep it clean
  • Signs indicating it’s time for a cleaning
  • The step-by-step process of how to clean ac filter
  • Reasons to consider professional help

By the end, you’ll be equipped with the knowledge to ensure your AC runs smoothly, providing you with clean, cool air throughout the hot summer months.

What is an AC Filter?

Before diving into the cleaning process, let’s understand the role of an AC filter. An AC filter is a component within your air conditioning system designed to trap dust, dirt, pollen, and other airborne particles as air passes through. Essentially, it acts as the first line of defense, preventing these contaminants from circulating throughout your home and improving indoor air quality.

Why is it Important to Keep Your AC Filter Clean?

Maintaining a clean AC filter is vital for several reasons:

  • Efficiency: A clean filter allows air to flow freely, ensuring your AC operates efficiently. When the filter becomes clogged with dirt and debris, it restricts airflow, forcing the system to work harder to maintain the desired temperature, leading to increased energy consumption and higher utility bills.
  • Improved Air Quality: As the filter captures airborne particles, it helps purify the air circulating in your home. A dirty filter compromises this function, allowing contaminants to recirculate, potentially exacerbating allergies and respiratory issues.
  • Extended Lifespan: Regularly cleaning or replacing your AC filter can prolong the lifespan of your air conditioning system. By reducing strain on the unit and preventing dirt buildup, you can minimize the risk of costly repairs or premature failure.
  • Cost Savings: A clean filter translates to lower energy bills. By maintaining optimal airflow, your AC operates more efficiently, reducing the amount of energy it consumes to cool your home.

Signs You Need to Clean Your AC Filter

Recognizing when your AC filter requires cleaning is essential for maintaining indoor comfort and system efficiency. Look out for these telltale signs:

Reduced Airflow:

If you notice weaker airflow from your vents, it could indicate a clogged filter obstructing the passage of air.

Increased Energy Bills:

A spike in your energy bills without a corresponding increase in usage may signal that your AC is working harder than usual, often due to a dirty filter.

Visible Dirt and Debris:

Inspect the filter regularly. If you observe a buildup of dirt, dust, or debris, it’s time for a cleaning.

Uneven Cooling:

Rooms in your home experiencing inconsistent cooling may be a result of restricted airflow caused by a dirty filter.

Musty Odors:

A foul or musty odor emanating from your vents could indicate mold or mildew growth, often due to a dirty filter retaining moisture.

How to Clean Your AC Filter in 9 Steps

Cleaning your AC filter is a relatively straightforward process that can be done with minimal tools and effort. Here’s a step-by-step guide:

1) Turn Off the Power:

Before beginning any maintenance on your AC unit, switch off the power at the circuit breaker to ensure your safety.

2) Locate the Filter:

Depending on your AC system, the filter may be located in different places, such as within the air handler unit, in a slot behind the return air grille, or within the ductwork. Consult your owner’s manual for guidance.

3) Remove the Filter:

Carefully remove the filter from its housing. Take note of its orientation to ensure you reinstall it correctly.

4) Inspect the Filter:

Examine the filter for dirt, dust, and debris. If it’s heavily soiled or damaged, consider replacing it rather than cleaning.

5) Vacuum or Wash the Filter:

For reusable filters, gently vacuum both sides using a soft brush attachment to remove loose dirt and debris. Alternatively, rinse the filter with water, using mild detergent if necessary. Avoid using excessive force or hot water, as this could damage the filter.

6) Allow to Dry:

If you’ve washed the filter, allow it to air dry completely before reinstalling it. Avoid reinstalling a damp filter, as this can promote mold growth.

7) Reinstall the Filter:

Once dry, carefully place the filter back into its housing, ensuring it’s properly seated and aligned according to the manufacturer’s instructions.

8) Restore Power:

After reinstalling the filter, switch the power back on at the circuit breaker to reactivate your AC unit.

9) Regular Maintenance:

Make it a habit to check and clean or replace your AC filter regularly, ideally every 1-3 months, depending on factors such as usage, indoor air quality, and the presence of pets.

Why You May Want to Call a Professional

While cleaning your AC filter is a DIY task for many homeowners, there are instances where professional assistance may be warranted:

  • Complex Systems: If your AC system is complex or you’re unfamiliar with its components, it’s best to leave the task to a qualified HVAC technician to avoid damaging sensitive parts.
  • Limited Accessibility: Some AC units are located in hard-to-reach areas, making filter removal and cleaning challenging for homeowners without the necessary equipment or expertise.
  • Time Constraints: If you have a busy schedule or prefer to leave maintenance tasks to professionals, hiring a technician can save you time and effort.
  • Comprehensive Service: HVAC professionals can perform thorough inspections and maintenance beyond just cleaning the filter, ensuring your entire system is in optimal condition.

Cost for Professional AC Filter Cleaning

The cost of professional AC filter cleaning can vary depending on factors such as your location, the complexity of the system, and any additional services provided. On average, expect to pay between $50 to $150 for a single service visit, which may include filter cleaning or replacement, inspection, and basic maintenance tasks.

While this cost may seem higher than DIY cleaning, professional service offers the assurance of thorough maintenance by trained professionals, potentially saving you money in the long run by preventing costly repairs or premature system failure.

How Often Should You Clean Your AC Filter?

Determining the ideal frequency for cleaning your AC filter depends on several factors:

  • Usage: If you run your AC frequently, especially during peak summer months, you’ll likely need to clean or replace the filter more often to maintain optimal airflow and efficiency.
  • Indoor Air Quality: Homes with pets, smokers, or occupants with allergies may require more frequent filter cleaning to remove pet dander, smoke particles, and other allergens from the air.
  • Filter Type: Disposable filters typically need replacement every 1-3 months, while reusable filters can be cleaned and reused for several years with proper maintenance.
  • Manufacturer Recommendations: Refer to your AC unit’s owner’s manual for specific guidelines on filter maintenance and replacement intervals recommended by the manufacturer.

In general, aim to inspect your AC filter monthly and clean or replace it as needed to ensure peak performance and indoor air quality.

After months of high water bills and feeling itchy, the Aquarius team came to the rescue. My 25 year old kinetico softener finally gave up and was constantly cycling. At the end of the service call we realized the old unit wasn't worth repairing. They sent out a salesperson the same day, providing a great range of options to fit my price point. My new softener arrived early so we were able to move up the install date. Install was flawless and we're back to having the softest water ever. I'm super happy with every interaction I've had with the Aquarius team. They are all super friendly, knowledgeable, and professional. I rarely leave reviews and only leave them when I'm really impressed. That's definitely the case with this company.

First, Aquarius responded to my interest in an RO system promptly. After deciding to commit to their solution, the installation, Including a water softner solution, it was scheduled the same week. Michael was the installer and he called when in transit and arrived right on schedule. We went over the work to be done and the placement of the equipment with only one issue that arose. The RO and water softener installation would not be a problem, but plumbing for the outdoor outlets would require additional material and labor, not included in the quote. I was looking forward to using the outdoor faucets without switching the system over. We elected to continue with the installation and Michael kept us informed throughout the day of his progress and completion time. He had everything cleaned up and provided us with a review of the system. To date, we are very pleased with the system and want to thank Michael for a great install. My only recommendation to Aquarius would be to take an additional step, during the initial meeting possibly, and physically look at the plumbing to ensure the quote covers all the materials to meet the customer request.

We have had our Aquarius services longer than a decade. During this time, the equipment has never failed us, but more importantly we have received absolutely outstanding customer service anytime we have needed anything. Today was no different, Wyatt came to our house to do our periodic inspection and was able to help troubleshoot a problem and find a solution the very same day. The entire time he was here, he kept his workspace, clean and orderly, and he was very polite and respectful of our home. The shocker came when he was about to leave and told me this was his fifth day On his own! Very impressed, not only with him as a person, but the quality of employees that come out out of Aquarius. Highly recommend this company.

I had an old furnace that was on its last legs and needed to be replaced ASAP.Day one: Service Tech arrived 2 hours after initial contact with Aquarius. Sales Rep arrived within an hour of the request. Deal was made and installation appointment scheduled for the NEXT DAY!Day two: Contacted by the installation team at 7:00 am. Arrived at 7:30. Finished up by 2:30.All of the staff that I dealt with were friendly, professional and great to work with. They explained everything very well. I was expecting to wait 2-3 weeks for a new furnace and A/C. This was all done inside of two days. I would 100% recommend Aquarius to anyone needing any type of home service.Tall Mike, Mike Sippel, Chris Oigard, Dave and Luke it was great to work with you. Thanks for everything!Oh, they like dogs too.
