Most housing societies today have compact building structures which makes it very difficult to install air-conditioners with ducts. House owners living in such societies prefer to choose a ductless HVAC system as it provides the required air-conditioning and also relieves them from the constant issues of cleaning or air leaks. But, if you have installed one such system in your home, you need to clean it to maintain it. If you are wondering how to clean a ductless HVAC system, then read on further.
Why do you Need to Clean a Ductless HVAC System Regularly?
- It is not enough to wipe the exteriors to these units as they get very dirty from inside as well.
- Proper cleaning is necessary for the smooth running of the AC, else it will not be able to provide the optimum cooling or heating you require.
- As the dust filters get clogged with dirt and dust, they will prevent the AC from providing good cooling. Furthermore, the air thrown from the AV will also be full of dust, making you breathe dirt and dust and catch respiratory diseases.
- If you live in humid weather, mold and mildew may easily develop inside your AC unit indoors as well as outdoors. These also lead to respiratory tract infections.
- If your HVAC is working harder than normal to provide cool air, then it may increase your EB bills too.

Cleaning the Outdoor Mini Split System:
Cleaning a mini-split system is no rocket-science. You can easily do this yourself without much time or effort. The modern ducts in heating and cooling systems are simpler to clean, as opposed to the traditional systems with ducts that required professionals to clean. Here is how you can clean a mini-split system yourself:
- Gather a water hose with sprayer, vacuum cleaner, fin comb, waste, dry rags, water, cleaning products.
- Next, disconnect your mini split system from the power supply.
- Clear away all the debris, pine needles and leaves that you may find sticking to the unit. Then, using a damp cloth with soap and water, clean the outdoor cabinet, rinse and dry properly.
- Now connect your water hose and spray nozzle and then scrub with a brush, removing all the dirt from the grill or fan cage. If the grill is removable, clean fan blades using a damp cloth with soap. Rinse and wipe the unit dry.
- Also look for any mold in the condensate pan and clean it with a bleaching solution or soap. Rinse well.
- Now let the water flow freely and check the drain hose for any objects that may be blocking the flow of air.
Cleaning the Indoor Mini Split System:
- Using an air handler, clean the exteriors with a damp cloth. Dry it again with a dry and clean rag.
- Remove the air filters and wash them thoroughly to clear the dirt, debris and dust. You must make it a point to clean the dust filters regularly.
- Also, clean the evaporator coil. This coil can be accessed by removing the cabinet from the unit. Remember, this one can be a messy job. You can also buy an AC cleaning kit to help you clean ductless systems. Such a kit contains all the chemicals and materials you need, including a disposable bag to collect all the dust. You can also use plastic or towels to protect the area while rinsing the unit. After all the coils are dry and clean, you can use a fungicide to prevent growth of mold.
