In addition to their size, Mitsubishi mini-split air conditioners are renowned for their ability to zone and chill specific rooms. The Mitsubishi mini-split air conditioner has two primary components, like the majority of central systems. It has an outdoor compressor/condenser in addition to an internal air-handling unit.
A bucket, flathead and Phillips screwdrivers, some clean cloths, evaporator coil cleaner, vacuum, and mild detergent are all required.
Don’t forget to use a metal ladder. You can also use an aircon cleaning cover to wash the main body of the unit, although that is optional. Be aware that you must unplug the power supply, turn off the breaker, and avoid touching the metal components with your hands before beginning the task.

Step 1. Remove the front panel and louvers
Simply lift the front panel until you hear a “click” sound to remove it. Holding the hinges firmly, take them off. Now, gently slide the centre and left side clips to the right to remove the horizontal louvers. To prevent breaking or cracks, take care not to use excessive force when removing the louvers.
Step 2. Remove filters and cover
Slide the filters down to release them from the hinges slowly. Now, using a flathead screwdriver, release the tabs on the side borders of the unit’s lid.
The louvers’ former location at the bottom is where the tabs are placed. Screws are located behind those tabs; remove them all with a Phillips head screwdriver.
Step 3. Loosen screw inside the blower wheel
You can see a screw on the innermost part of the blower wheel opening on the right. Use a Phillips head screwdriver to simply loosen it rather than remove it entirely.
Step 4. Unfasten other screws and remove the blower wheel
Remove the three screws that are now fastened to the left side of the unit’s body. Pull the drain pan beneath the evaporator slowly next. In the event that the pan is dripping with water, use a towel. The blower wheel can then be removed by pulling the evaporator.
Step 5. Clean the front panel, filters, and blower wheel
Avoid using any scrubbing brush or rough sponge when cleaning the front panel, filters, and blower wheel. Avoid using cleaning products that contain benzene, thinner, pesticides, or polishing powder. Use diluted mild detergents exclusively, if at all possible.
Use a clean, moist towel to wipe the louvers and front panel of any dirt. The horizontal louvers shouldn’t be rinsed or soaked.
Every two weeks, the Nano Platinum filter needs to be cleaned. To get rid of the filth, either use a vacuum or a water rinse. If you decide to rinse it, be careful to dry it thoroughly in the shade as opposed to in the sunshine.
The blue filter is the air-cleaning filter, and it needs to be cleaned every three months. With a vacuum cleaner, you can first clean it. However, if vacuuming alone is unable to get rid of the filth, you must first soak the itemalong with its framein lukewarm water before rinsing. When finished, dry it in the shade rather than in the sun.
Regularly changing the filters in your air conditioner is one method to guarantee the quality of the air it produces. For the Mitsubishi mini-split, the air-cleaning filter needs to be changed every year, especially once washing it is no longer sufficient to get rid of the odor and debris.
The air that your air conditioner produces is purified with the aid of the deodorizing filter. To regain its deodorizing function, your Mitsubishi mini-black split’s filter needs to be cleaned frequently. It should be vacuumed or given a 15-minute soak in lukewarm water to clean it and its frame every three months as advised.
Because filthy filters would lead to condensation in the air conditioner, you should always clean your filters. Condensation aids in the development of fungus and mold. For you and your family, fungi can be extremely dangerous to your health.
Cold air cannot get through the evaporator if dirt and dust are clogging your filters. As a result, the machine must work harder merely to attain the desired temperature, which increases energy consumption.
The blower wheel needs to be cleaned by pouring some diluted mild detergent on it once you’ve done cleaning the filters. Rinse the detergent after allowing it to rest for 5 to 10 minutes. After drying it one again in the shade.
Step 6. Clean main body
Install the cleaning cover on the main body and then clean it. This will prevent any water from spilling or splashing out while you are cleaning the appliance. Don’t forget to place the cleaning cover’s included hose inside a bucket.
Spray an evaporator coil cleaning on the coils right now, and then wait a few minutes for the foam to go away. Spray water on the coils to rinse them. Dry off the coils.
A mini split can you clean it yourself?
Two main parts make up a mini-split HVAC system: an indoor unit and an outside unit. To prevent the consequences we previously described, you should clean both units on a regular basis. Mini-split units should typically be cleaned once every four to six weeks for best results. However, for more detailed information and directions on how frequently the system has to be cleaned, go to the owner’s manual for your particular system.
Turn off the system and unplug it from the power source before cleaning either device. By doing this, you can keep yourself safe and prevent getting electrocuted while cleaning near the electrical parts of the system. We advise entirely removing the power cable from the socket or main electrical panel for the sake of safety.
The next step in preparing to clean the interior or exterior unit of your mini-split is to gather the required supplies after turning off the system’s power source. Fortunately, you can clean your mini-split efficiently without using a lot of fancy or expensive cleaning equipment. Usually, you only need the following things:
- a fresh, moist cloth
- a dry, spotless cloth
- Household cleaners (refer to your owner’s manual for a list of recommended cleaners)
- an attachment for a brush nozzle on a vacuum
You will require the following items for a thorough clean:
- Coil cleaning equipment
- Treatment for condensate drain pumps
- drain cleaner for condensation
The time has come to begin cleaning your interior and exterior units once you have acquired the required tools.
Cleaning the Indoor Unit of Your Mini-Split
Start by simply washing down the unit’s outside surface with a moist cloth and then drying it with a dry cloth to clean the indoor unit of your mini-split. The mini-split filter should then be located, removed, and cleaned with water and a mild detergent. You’ll need to take the system’s front panel off to accomplish this. Place the filter back into the system where you found it after thoroughly cleaning it and allowing it to completely dry by air.
It’s time to move on to the evaporator coil once you’ve cleaned the filter. Remove the unit’s cabinet to get to the coil. To remove any dirt, mold, or other debris that has developed on the coils, use a clean, dry cloth or a cloth that has coil cleaner on it. Put the cabinet and front panel back on the unit once you’ve finished cleaning the coils.
Last but not least, you should clean the drain and condensate pan. If you see any mold growth or an accumulation of other difficult-to-remove debris, you might want to clean the pan and drain with bleach or soapy water.
Cleaning the Outdoor Unit of Your Mini-Split
Start by removing any debris from within, on, or around your mini-exterior split’s unit, such as twigs, leaves, or grass. The exterior of the outdoor unit should then be sprayed down using a garden hose or coil cleaning apparatus. After that, wipe off the housing of the unit of any dirt or grime that has gathered there with a cloth. After cleaning the housing, be careful to wipe it down with a cloth to dry it.
Next, spray and scrub the exterior unit’s grille and fan cage with your hose and a cloth or cleaning brush. If you can, remove the grille once it has been thoroughly cleaned, then carefully clean the fan blades with a damp cloth and soap. Use cautious to prevent bending or other damage to the metal blades since they are delicate. To avoid rusting, after cleaning the blades, rinse them with water and dry them with a fresh cloth.
Use a dry towel to wipe down the interior of the appliance and a vacuum attachment to easily suck up any dust or other dirt. Use a hose and a coil cleaner to clean the external unit’s coils.
Check the condensate pan after cleaning the interior, just as you did with the indoor unit. Consider using a bleach solution to get rid of any mold development before giving the pan a good water cleaning. The drain hose should then be cleaned with soap and water to get rid of any dirt or debris that might be obstructing the water’s flow.

How do I clean the filters in my air conditioner and how often should I do this?
Cleaning the filters on the indoor unit of your air conditioner is typically a quick and easy task for wall-mounted systems. You must routinely inspect and clean the filters if you often use your air conditioner. If your air conditioner is used every day, we advise doing this at least once every several months. At the beginning of the heating and cooling season, you should clean your filters if you don’t use your air conditioner frequently. The filters’ design makes it simple to wash them with soap and water.
