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.
