Quick And Easy Steps In Cleaning A Mini Split Ductless Air Conditioner

Cleaning a ductless mini-split air conditioner is essential for maintaining its efficiency and prolonging its lifespan. If you’re wondering about the steps to clean this type of AC, we have thoroughly researched and gathered expert advice to provide you with a comprehensive solution.

Below are the procedures to effectively clean a ductless mini-split air conditioner:

1. Begin by opening the cover of the indoor air handler and removing the filters.
2. Rinse the filters using warm or room temperature water.
3. Lift and take out the front panel and louvers.
4. Unscrew and remove the bodyshell.
5. Install an air conditioner cleaning cover kit and apply an evaporator coil cleaner to eliminate dirt and grime.
6. Use a pressure washer with a pressure of around 125 PSI on the air handler.
7. Clean the bodyshell and louvers outside using the pressure washer.

Please note that these steps specifically address the cleaning of the inside air handler of a ductless mini-split system. Additionally, we will discuss how to clean the outside condenser unit and provide information about the location of filters in a mini-split air conditioner.

Is It Necessary To Clean Ductless Air Conditioners?

Regular cleaning is crucial for maintaining the efficiency of ductless mini-split AC units. It is recommended to clean these cooling systems at least once every quarter. However, the cleaning frequency may vary depending on factors such as the location of the property and living conditions.

For instance, if the house is located in a dusty area, it is advisable to clean the filters of the ductless air conditioner at least once a month. Similarly, households with pets may require more frequent cleaning to remove pet hair and dander.

Taking preventive measures can also help minimize the accumulation of dirt and debris in the mini-split system. One such measure is using a mini-split line cover to protect the connections between the outside condenser and the indoor air handler, preventing the entry of dust and small particles.

Where Can You Find The Filters In A Mini-split Air Conditioner?

The location of filters in a mini-split air conditioner varies depending on the specific model of the unit. Generally, you can access the filters by opening or removing the front panel cover.

However, when opening the air conditioner to locate the filters, it is crucial to ensure that the appliance is turned off to minimize the risk of electric shock.

Alternatively, you can refer to the appliance’s owner’s manual or contact the manufacturer’s customer service hotline for assistance. The contact information should be available on the air conditioner’s packaging or a sticker on the unit.

How Do You Clean A Ductless Air Conditioner?

Prioritize safety and caution throughout the cleaning process. For instance, if you are using a stepladder, make sure not to put your weight on the last step to prevent accidents. It is also helpful to have someone assist you by holding the ladder securely.

Once again, ensure that the ductless mini-split air conditioner is switched off to avoid potential hazards. You can either disconnect it from the power source or turn off the unit’s switch from the circuit breaker panel.

It is recommended to wear a mask or respirator during the cleaning process to protect yourself from airborne dirt and dust particles. This safety gear will help prevent respiratory issues.

After completing the necessary preparations, follow the step-by-step guide below to clean the air conditioner:

Required Tools

• Screwdriver
• Cleaning cover kit
• Evaporator coil cleaner
• Pressure washer

Step-By-Step Guide

1. Open the front cover of the air conditioner and remove the filters.
2. Rinse the filters in a sink using warm or room temperature water.
3. Carefully lift the front panel and set it aside.
4. Remove the louvers, which are responsible for assisting the airflow.
5. Unscrew the screws securing the bodyshell. Remove the air handler’s cover and keep it aside.
6. Install the cleaning cover kit and use the evaporator coil cleaner on the coils. Allow the foam to sit for a few minutes to remove dirt and grime from the coils.
7. Use a pressure washer with a pressure of approximately 125 PSI on the air handler. Avoid using a higher setting to prevent damage to the appliance.
8. Take the bodyshell and louvers outside and rinse them thoroughly with the pressure washer.
9. Reinstall the removed parts and test the unit to ensure its efficiency.

Please note that the above steps focus solely on cleaning the indoor air handler. Cleaning procedures for the outside condenser unit will be discussed in a later section of this post.

How To Clean Outside Condensers?

Before attempting to clean the outside condenser, locate the disconnect switch and ensure that the unit is not receiving power. Operate the switch to turn off the power supply.

Avoid using a power washer on the condenser unit, as the high water pressure can damage the coil fins.

For cleaning the outside condenser, you generally don’t need any special tools. Follow these steps using a regular garden hose:

Step-By-Step Guide:

1. Spray water from the garden hose onto the outside condenser. Direct the spray downward to collect dirty water at the base of the unit.
2. If necessary, partially block the hose’s output with your finger to increase pressure for stubborn dirt.
3. Allow the condenser to air dry or use a wet/dry vacuum cleaner to remove excess moisture, preventing additional dirt and dust from accumulating on the unit.

How To Clean Mold Out Of A Mini-split Air Conditioner?

When cleaning mold from a mini-split air conditioner, it is vital to prioritize safety. Wear protective equipment, including a respirator, long-sleeved clothing, and rubber gloves, to prevent inhalation of mold spores and skin contact.

Follow these steps for cleaning mold:

Required Tools

• Mold control spray
• Paper towels

Step-By-Step Guide

1. Remove the plastic cover of the air handler.
2. Use mold control spray on paper towels and wipe the indoor unit.
3. Clean the air handler’s surfaces thoroughly using additional paper towels or a clean cloth.
4. Repeat steps 2 and 3 as needed.
5. Reinstall the plastic cover once the cleaning process is complete.

Please note that it is nearly impossible to completely eliminate mold spores as they naturally exist. However, regular maintenance and checkups can help reduce excess moisture and minimize mold and mildew growth in air conditioners.

Conclusion

Removing dirt and debris from a ductless mini-split air conditioner can be a DIY task. By utilizing the appropriate equipment, such as an evaporator coil cleaner and an air conditioner cleaning cover kit, and following safety precautions, you can effectively clean your air conditioner. Remember to turn off the unit before cleaning and seek professional assistance or refer to the manufacturer’s guidelines if needed.
