The Ultimate Step-by-Step Guide to Mastering Ceiling-Mounted Air Conditioner Cleaning

1 Why Clean Ceiling-Mounted Air Conditioners?

• Improve cooling efficiency, increase lifespan, stabilize operation, and optimize energy savings.
• Provide clean, dust-free air, preventing skin and respiratory problems.
• Maintain the unit’s new condition, promptly fixing potential faults. Detect and address any incidents or risks timely and efficiently.

• Always unplug the ceiling-mounted air conditioner from the electrical outlet before cleaning.
• Avoid using flammable cleaning agents or toxic solutions. Opt for dish soap, diluted vinegar, or specialized cleaning products instead.
• Refrain from using harsh chemicals, such as bleach, or substances like gasoline, as they may damage the paint on the air conditioner.
• Use a soft cloth or dry sponge to wipe away moisture, preventing liquids from seeping into electrical components and causing short circuits.

2 Simple Steps to Clean a Ceiling-Mounted Air Conditioner at Home

Step 1: Clean the Outdoor Unit of the Ceiling-Mounted Air Conditioner

The first step is to disconnect the power by unplugging the unit before cleaning to ensure your safety.

First, remove the front grille to access the internal components. Then, use a spray bottle to rinse the condenser, outdoor fan, and grille, removing any accumulated dust. Reassemble the parts in the reverse order.

Step 2: Clean the Air Filter

The air filter can be cleaned using a vacuum cleaner or by washing it with warm water and a mild detergent. Afterward, dry it thoroughly and place it in a sunlight-free area.

Cleaning the air filter ensures that the unit can effectively remove dust, providing clean air.

Step 3: Clean or Replace the Plasma Filters

The plasma filter, located behind the air filter, can be cleaned by soaking it in water with a mild detergent to remove dust and mold. This helps protect your health and skin while preventing respiratory problems.

Step 4: Check for Unnecessary Leaks and Noises

After cleaning the outdoor and indoor units, perform a test run to check for electrical leaks or water dripping. If the unit emits an unusual noise, turn it off and contact the nearest service center for assistance.

3 Signs That Your Ceiling-Mounted Air Conditioner Needs Cleaning

The most obvious sign is a decrease in cooling efficiency, indicated by warm air and reduced cooling capacity. This signifies that the unit requires cleaning after prolonged use.

Another sign is a higher electricity bill, indicating that dust and dirt have accumulated in the unit, causing blockages. As a result, the air conditioner has to work harder to produce cool air.

Additionally, a musty odor emanating from the air conditioner is a sign that it needs cleaning.

Ceiling-mounted air conditioners should be cleaned regularly, at least once every six months, to maintain optimal cooling performance and prolong their lifespan.
