Maintaining your Reiwa window portable AC by yourself is simple and can save you from spending on technician fees. After seven months of heavy use, your AC likely needs thorough cleaning to function optimally again.
Routine cleaning every three months is recommended to avoid severe dirt buildup and ensure efficient cooling. Start by unplugging the unit for safety and prepare your space by moving items below the AC, as water might drip during the process.
Preparation for Disassembly
First, remove the lock if any, then carefully take out the AC unit from the wall. The unit weighs about 19 kilograms, so handling it with caution is vital. Avoid installing the AC too high to make future maintenance easier and safer by using a sturdy chair to reach it.
Opening the Casing
Unscrew the left side of the front cover cautiously to access the internal components. Be aware that opening the casing might void the warranty label, but the savings on maintenance costs make it worthwhile. Detach the cover slowly from the bottom until it clicks free; avoid forcing it to prevent damages.
Removing Internal Components
Next, remove all screws from the side casings—three on the left, two at the right-bottom, and two at the top—to release the metal casing inside. Carefully take out the styrofoam packing; be gentle to prevent breakage. The inside tends to accumulate significant dirt after months without cleaning, requiring thorough attention.
Protecting Sensitive Parts
Use plastic wraps to tightly cover the PCB module and monitor PCB to prevent water damage during cleaning. Secure the plastic with tape or rubber bands to prevent leaks. The thermal sensor cables wrapped in plastic can get wet but usually remain safe. Avoid touching the thin copper pipe on the left as it is fragile and prone to breaking.
Proper Cleaning Method
For cleaning, use a mild spray from a jet cleaner, watering can, or gentle hose spray to wash the evaporator and metal fins. Avoid hard sprays that can bend the fins and block airflow, reducing cooling effectiveness. Soft brushes or old toothbrushes are ideal for hard-to-reach spots. Adding a gentle detergent like dishwashing liquid enhances the cleaning process.
Advantages of Self-Maintained Reiwa AC
Reiwa window portable AC allows easy DIY upkeep without professional help, saving technician costs entirely, which typically could be around $0 every quarter. Its compact design and weight make it manageable for individuals to clean similarly to household fans. The unit can cool rooms up to 3×3 meters down to around 16 degrees Celsius, making it perfect for small bedrooms or rental spaces.
Electrical Power Efficiency
Despite its powerful cooling, the AC consumes roughly 350 watts with a startup power of 650 watts, compatible with typical household power limits like 900 watts. This energy efficiency ensures you can run several other appliances like refrigerators and televisions without electrical issues.
Owning a Reiwa window portable AC means a low initial investment of about $140 (converted from Rp2 million) and minimal ongoing costs. Its maintenance routine is straightforward and safe when following these guidelines, keeping the unit durable and performance optimal. This approach provides long-term savings and efficiency without recurring technician fees.
