Mini-split HVAC systems, like Daikin, Mitsubishi, Fujitsu and Hitachi mini-split’s, are popular for their high efficiency and ease of use. However, like all appliances we have at home, mini-split’s require regular maintenance to keep them running smoothly. Giving your mini-split a good clean and wipe down is an essential part of that upkeep.
If you’re unsure how to clean a mini-split or feel overwhelmed by the process, our guide will take you step-by-step through the process!
Why Cleaning Your Mini-Split Is Crucial
Keeping your mini-split clean offers numerous benefits:
1. Maximized Efficiency
Dust, dirt, and grime can build up over time, reducing your mini-split’s ability to cool or heat your home effectively. A clean mini-split works at its best without any blockage to slow it down.
2. Prevent Premature Wear
Regular cleaning helps avoid premature wear on your mini-split’s internal components, potentially saving you from expensive repairs down the line.
3. Improved Air Quality
Dirty mini-split units can circulate dust, mold spores, and other pollutants throughout your home, which can be harmful to your health, as well as those living in your house too.
4. Lower Energy Bills
If your mini-split is clogged with debris, dirt and dust, it has to work harder to maintain the desired temperature, which increases energy consumption and your monthly A/C bills. We want our mini-split’s to work smarter, not harder!
Maintaining a regular cleaning schedule for your mini-split’s indoor and outdoor unit will not only extend the life of your mini-split but also save you money over time.
How Often Should You Clean Your Mini-Split?
So the big question - How often should I clean my mini-split?
As a general rule, both the indoor and outdoor components of a mini-split system should be cleaned every four to six weeks to maintain optimal performance.
However, it’s always a good idea to refer to your owner’s manual for any specific guidelines or recommendations for your mini-split brand.
Before starting the cleaning process, turn off the power to your mini-split system. Disconnect your mini-split from the power supply to eliminate any risk of electrocution while working on the electrical components. Either unplug the unit or switch it off at the main electrical panel.
Essential Tools for Cleaning Your Mini-Split
Cleaning your mini-split doesn’t require a lot of tools, you will need a few basic supplies you can find at home:
- Clean, damp cloth.
- Clean, dry cloth.
- Household cleaners (consult your specific mini-split owner’s manual for recommended types).
- Garden hose.
- Vacuum with a brush nozzle attachment.
For deeper cleaning, you may also need:
- Coil cleaning tool.
- Cleaning brush.
- Spray bottle.
- Condensate drain pump treatment.
- Condensate drain cleaner.
With these tools in hand, you’ll be ready to begin cleaning both the indoor and outdoor units!
Cleaning the Indoor Unit of Your Mini-Split
1. Wipe Down the Exterior
Start by cleaning the exterior surface of your mini-split’s indoor unit. Use a damp cloth to wipe it down, removing dust or grime, and follow up by drying it with a clean, dry cloth.
2. Clean the Filters
Next, locate and remove your mini-split’s air filters from the front of the indoor unit. These filters trap dust and debris, so they need regular cleaning to prevent clogging.
Wash your air filters with mild detergent and warm water, then allow them to air-dry completely before reinstalling them.
Cleaning these filters ensures that air flows smoothly through the system and helps maintain clean air in your home.
3. Clean the Indoor Evaporator Coil
The evaporator coil inside your mini-split’s indoor unit can collect dirt and dust over time. To access it, remove your mini-split’s cabinet or front panel.
Wipe the coil clean using a cloth - either dry or dampened with a coil cleaning solution. Be careful not to bend or damage the coil fins. Once clean, reattach the cabinet and front panel.
4. Clean the Condensate Pan and Drain
Your mini-split’s condensate pan collects water from the air as it cools. If not cleaned regularly, it can become a breeding ground for mold and bacteria.
Use soapy water or a bleach solution to clean the pan, especially if you notice any signs of mold. Also, check your mini-split’s drain to ensure it isn’t clogged, as a blocked drain can lead to water damage or mold growth in the system.
Cleaning the Outdoor Unit of Your Mini-Split
1. Remove Debris
Outdoor mini-split units are exposed to the elements and can accumulate debris like leaves, grass, and dirt.
Clear any debris around the unit to ensure proper airflow. This simple step can have a significant impact on the efficiency of your mini-split system.
2. Clean the Exterior and Grille
Use a garden hose to gently spray down the outside of your mini-split unit.
After rinsing, wipe the unit’s housing with a clean cloth to remove any leftover dirt. Make sure the exterior is dry to prevent rusting.
3. Clean the Fan Blades
If your mini-split’s outdoor grille is removable, take it off to access the fan blades.
Use a damp cloth and mild soap to clean the blades, being gentle to avoid bending or damaging them.
Once clean, rinse the blades with water and dry them thoroughly with a cloth. Properly cleaning your outdoor mini-split fan helps the unit run smoothly and prevents strain on the motor.
4. Clean Your Mini-Split’s Outdoor Coils
Your mini-split’s outdoor coils are an essential part of your mini-split’s cooling system.
To clean them, use a coil cleaner and hose to spray away any dirt or debris. This will improve heat transfer and ensure your system operates efficiently.
5. Inspect the Condensate Pan and Drain
As with your mini-split’s indoor unit, check the condensate pan for signs of mold or buildup.
Clean it with a bleach solution if necessary. Additionally, wash the drain hose with soap and water to prevent clogs and ensure that water drains freely.
