Maintaining a Healthy Climate Control: Cleaning Air Conditioner Filters

June 21, 2023

To ensure optimal performance, it's important to clean your air conditioner filters regularly. The specific instructions for your system can be found in the manufacturer's instruction manual. If you no longer have the manual, you can visit the manufacturer's website to access a copy.


Here's what you'll need for the cleaning process:


Vacuum cleaner

Gloves

Face mask

Safety glasses

Cleaning cloth

Soap/detergent

Warm water

Step ladder (if necessary)


Before you begin, make sure to switch off the power at the wall!


Step 1: Removing the Filters


The process of accessing the air filters may vary depending on the type of system, but the cleaning method remains the same.


For split systems and window air conditioners, lift the front panel from the bottom and slide out the filters.


In the case of ducted air conditioning, the filters are usually located at the return vent, which can be found within a wall or the roof. You might need a step ladder to reach them. Unscrew or slide open the panel and lift the filter out. Be cautious of falling dust and wear a mask and goggles for protection.


Step 2: Vacuuming Dust Buildup


Cleaning the clogged air filters can be done in various ways, but using a vacuum is the easiest and least messy option. Gently run the vacuum over the filter, ensuring that you suction all the surface material. Remember to handle the reusable filters delicately to avoid any damage.


Alternatively, you can take the filters outside and brush off the dust over a waste bin.


Step 3: Rinsing in Warm Soapy Water


Fill a sink or tub with warm, soapy water and wash the filters. A mild detergent will suffice for this task.


Since filters can be fragile, it's recommended to use a cleaning cloth instead of a coarse brush or scouring pad. Once cleaned, allow the filters to dry completely in a safe area.


Replacement air filters can be obtained from the manufacturer when needed.


Step 4: Cleaning the AC Unit


Gently vacuum around the filter area to remove any residual dust. Wipe the surroundings with a damp cloth as necessary. After ensuring that both the filters and AC unit are completely dry, slide the filters back in, close the cover, and switch the power back on.


Cleaning the Outdoor Unit


The outdoor unit also requires attention. Begin by sweeping or blowing away any leaves or debris surrounding it, as they can obstruct airflow around the internal coils. Next, wipe down the unit to remove dirt buildup and excessive grime.


Using a vacuum or dustbuster, clear any dust that may have entered through the air intake. However, it's important to note that removing the covers yourself is not advised, as it could potentially damage the unit and void the warranty. Instead, it's best to leave the cleaning of the internal components to a professional during an annual service.


By following these steps, you'll be able to maintain your air conditioning unit and extend its lifespan while ensuring a constant supply of fresh, clean air for healthier breathing. Regular maintenance and cleaning are essential for both your comfort and energy savings in the long run.

Most HVAC problems don’t start with a breakdown. They start quietly—months or even years earlier—because of one simple habit almost every homeowner has. They wait until something stops working to think about their HVAC system.  HVAC Systems Don’t Fail Suddenly—They Wear Out Your furnace or air conditioner doesn’t usually “just die.” It wears down gradually through: Longer run times Higher electrical draw Rising internal temperatures Increased vibration and stress By the time a system shuts off or trips a safety, the damage has often been happening for a long time. That’s why emergency breakdowns almost always come with higher repair costs. What Actually Causes Premature HVAC Failure Contrary to popular belief, age alone isn’t the biggest killer of HVAC equipment. The most common causes are: 1. Small Issues Left Unchecked A weak capacitor, dirty flame sensor, or failing blower motor doesn’t always stop the system—but it forces other components to work harder. That added strain shortens the life of the entire system. 2. “It’s Still Working” Syndrome Homeowners often delay service because: The house still heats or cools The system hasn’t locked out There’s no obvious warning light Unfortunately, HVAC systems can operate while slowly damaging themselves. 3. Deferred Maintenance Costs More Than Repairs Skipping routine service doesn’t save money—it shifts the cost to: Larger repair bills Emergency service calls Shortened system lifespan A simple maintenance visit can prevent a $1,500 breakdown. Why Breakdowns Always Happen at the Worst Time There’s a reason furnaces fail during cold snaps and ACs quit during heat waves. Extreme weather forces systems to: Run longer Start more frequently Operate at peak capacity If a component is already weakened, that’s when it finally gives up. What “Normal Operation” Should Actually Look Like A healthy HVAC system should: Start smoothly Run consistently (not constantly) Shut off cleanly Maintain temperature without drastic swings Sound the same month to month Changes in sound, runtime, or performance are early warning signs—not inconveniences. The Smarter Way to Think About HVAC Ownership Instead of asking: “Is it broken?” A better question is: “Is it operating the way it should?” That mindset shift alone prevents many major HVAC failures. Final Thought Your HVAC system is one of the most expensive mechanical systems in your home. Treating it as something to react to—rather than maintain—almost guarantees higher costs and shorter lifespan. The homeowners who get the longest life and lowest total cost aren’t lucky. They’re proactive. Serving Wooster, OH, and surrounding communities since 1993, we are a locally owned and operated HVAC contractor working with a variety of heating and cooling systems.
