An air conditioner is an essential appliance in our homes, especially during hot summers or humid spring and autumn seasons. However, over time, the interior of the air conditioner accumulates dust, mold, bacteria, and odors. This not only affects the efficiency of the air conditioner but can also lead to respiratory discomfort, allergies, or skin issues.

Regularly cleaning your air conditioner offers several benefits:

• Improve air conditioner efficiency: Removing dust and dirt allows the air conditioner to cool down faster.
• Save on electricity bills: A clean air conditioner operates more efficiently and consumes less power.
• Extend lifespan: Regular maintenance helps reduce the chances of malfunctions.
• Maintain health: Reduce dust mites and mold in the air, improving air quality.

It's not necessary to wait until your air conditioner "breaks" to clean it. The following signs indicate when it's time to clean your air conditioner:

• Odor development: If there is a musty or unusual smell when the air conditioner is turned on, it indicates mold growth inside.
• Reduced cooling or weakened airflow: It could be due to clogged filters or a dirty evaporator coil.
• Dripping or leaking water: Blocked drainage pipes or excessive condensate inside.
• Regular maintenance: It is recommended to clean your air conditioner annually, or every six months if used frequently (such as running all day).

The best time to clean your air conditioner is before the transition between spring/summer or autumn/winter seasons, ensuring optimal performance before the peak usage season.

Used to dismantle the air conditioner casing.

For wiping dust and preventing water stains from dripping.

To brush away dust from intricate parts of the air conditioner.

Designed for use on the evaporator coil and fan, safe and effective.

For spraying clean water to rinse.

To place under the air conditioner to prevent water drips from dirtying the walls or floor.

To avoid inhaling dust or coming into contact with cleaning agents.

To collect drained dirty water.

It is also recommended to wear old clothes during the cleaning process to avoid getting wet or stained by cleaning agents.

• Ensure to unplug the power cord or switch off the main power to avoid the risk of electric shock.
• Lay down a waterproof cloth or garbage bag beneath the air conditioner to prevent water from flowing onto the walls or furniture.

• Use a screwdriver to open the air conditioner casing, being careful not to damage the fasteners.
• Take out the filter; you can use a vacuum cleaner to remove loose dust before cleaning it.

• Rinse the filter with clean water; if it's too dirty, lightly scrub it with a mild detergent.
• Wipe the casing clean with a cloth, especially around the air outlet blades.
• When drying, avoid direct sunlight to prevent deformation or aging.

• Evenly spray the air conditioner-specific cleaning agent on the evaporator coil (usually the metal fin part).
• Let it sit for about 10 minutes, then use the spray bottle to rinse off the dirt with clean water.
• If the air conditioner fan is visible, carefully clean the fan blades with a brush.

• After all parts are completely dry, reassemble them.
• Plug in the unit, run it in fan mode for 30 minutes; this will help dry the interior and remove any cleaning agent residue.
• Finally, switch to cooling mode to ensure normal operation, cool airflow, and no odors.

In addition to regular deep cleaning, you can also perform the following simple maintenance tasks monthly:

• Clean the filter every 2-4 weeks, especially during frequent summer use.
• Avoid leaving the air conditioner on for extended periods without turning it off; set automatic shutdown timers to prolong its lifespan.
• After use, run the fan or electric fan for 10 minutes to dry the interior, helping prevent mold growth.
• Maintain cleanliness indoors to reduce dust sources and prevent rapid dust accumulation on the filter.

• Avoid using cleaning agents containing corrosive ingredients, as they may damage the evaporator coil and plastic parts.
• If unfamiliar with disassembly or construction during cleaning, be sure to refer to the user manual.
• If there is significant dirt buildup inside the air conditioner, unusual sounds, continuous leakage, or extremely weak airflow, it is advisable to seek professional technicians for home cleaning.
• Do not attempt to dismantle the internal circuit boards or refrigerant-related components of the air conditioner to avoid safety issues.

It is recommended for households to clean their air conditioner at least once a year. If the air conditioner is used for long hours daily (e.g., more than 8 hours per day), cleaning every six months is ideal. The filter should be cleaned every 2-4 weeks to prevent dust buildup.

As long as the correct steps are followed, DIY cleaning will not damage the air conditioner. The key is to first disconnect the power, operate safely, avoid excessive force, and refrain from using strong acidic or alkaline cleaning agents. If unsure about disassembly, it is recommended to clean only the filter and external parts.

It is advisable to use a specialized air conditioner cleaning agent. These products have milder ingredients that do not harm metal or plastic components, effectively removing oil stains and mold from the evaporator coil. Avoid using bathroom cleaners or products containing bleach, as they can corrode parts.

Yes, in most cases, a musty smell indicates mold growth due to accumulated moisture or dust on the fan blades. Deep cleaning, including the evaporator coil and air outlet blades, is necessary in such situations. If the odor persists after cleaning, professional inspection is recommended.

Yes, the outdoor unit also requires regular cleaning. Dust or fallen leaves blocking the heat exchanger fins can affect the overall efficiency of the air conditioner. Use a brush or vacuum cleaner to clean dust around the casing and heat exchanger fins to maintain proper ventilation.

冷氣是家中不可或缺的電器，特別是在炎熱的夏天或濕悶的春秋季節。然而，長期使用冷氣機後，內部會累積灰塵、霉菌、細菌與異味，這不僅影響冷氣的運作效率，還可能造成呼吸道不適，甚至引發過敏或皮膚問題。

定期清潔冷氣可以帶來以下幾個好處：

• 提升冷氣效能：清除灰塵與污垢能讓冷氣更快速降溫。
• 節省電費：乾淨的冷氣更有效率，運轉更省電。
• 延長使用壽命：定期保養有助於減少故障機率。
• 維護健康：降低空氣中塵蟎與霉菌的數量，改善空氣品質。

並不是等冷氣「壞了」才要清洗。以下情況都是提醒你該清洗冷氣的訊號：

• 異味產生：開冷氣時有霉味或怪味，表示冷氣內部發霉。
• 冷氣不冷或變弱：可能是過濾網堵塞或冷排太髒。
• 滴水或漏水：排水管阻塞或內部冷凝水過多。
• 定期保養：建議每年清洗一次，若常用（如開整天）則每半年清洗一次。

最佳清洗時機：在春夏交接或秋冬換季前清洗冷氣最合適，這樣能在使用旺季前確保冷氣最佳效能。

用來拆卸冷氣外殼。

擦拭灰塵與防止水漬滴落。

刷除冷氣細部灰塵。

針對冷排與風扇使用，安全又有效。

噴灑清水沖洗。

鋪在冷氣下方，避免水滴弄髒牆面與地板。

避免吸入灰塵或接觸清潔劑。

收集排出的污水。

另外建議在清潔過程中穿著舊衣服，以免沾濕或沾染清潔劑。

• 確保拔掉電源插頭或關閉電源總開關，避免觸電危險。
• 將防水布或垃圾袋鋪好，固定於冷氣下方，避免水流到牆上或家具。

• 使用螺絲批打開冷氣外殼，小心不要弄壞扣件。
• 將濾網取出，可用吸塵器先吸去浮塵，再進行清洗。

• 用清水沖洗濾網，若太髒可用中性洗潔精輕刷。
• 外殼也可以用抹布擦拭乾淨，尤其是出風口的葉片位置。
• 晾乾時避免太陽直曬，以防變形或老化。

• 將冷氣專用清潔劑均勻噴在冷排（通常為金屬鰭片部分）。
• 靜置約10分鐘後，使用噴水瓶補噴清水沖掉污垢。
• 若冷氣風輪可見，也可使用毛刷小心清潔風扇葉。

• 等所有部分徹底乾燥後再裝回。
• 裝好後插電，先用送風模式運轉30分鐘，可幫助內部乾燥、去除清潔劑殘留。
• 最後轉為冷房模式，確認是否恢復正常運作、出風清涼無異味。

除了定期深層清潔，每月也可以做以下簡單保養：

• 每2～4週清洗一次濾網，尤其是夏天使用頻繁時。
• 避免長時間開冷氣不關機，可設時段自動關閉，延長壽命。
• 使用完畢後，開送風或電風扇10分鐘讓內部乾燥，有助防霉。
• 保持室內整潔減少灰塵來源，避免濾網過快堆積灰塵。

• 避免使用含腐蝕性成分的清潔劑，可能損壞冷排與塑膠零件。
• 清潔時若不熟悉拆卸或構造，務必參考使用說明書。
• 若冷氣內部積垢嚴重、有異聲、持續漏水或風量極弱，建議請專業技師到府清洗。
• 嚴禁自行拆卸冷氣內部電路板或冷媒相關部分，以免造成安全問題。

建議一般家庭至少每年清洗一次冷氣，如果冷氣長時間使用（如每日開超過 8 小時），則每半年清洗一次較理想。濾網部分建議每 2～4 週清洗一次，避免灰塵堆積。

只要按照正確的步驟進行，不會對冷氣造成損壞。重點是先切斷電源、安全操作，避免用力過猛或使用強酸強鹼清潔劑。若不確定如何拆機，建議只清潔濾網與外部。

建議使用冷氣專用清潔劑，這類產品成分較溫和、不傷金屬與塑膠，且能有效清除冷排上的油污與霉菌。千萬不要使用浴室清潔劑或含漂白水的產品，否則容易腐蝕零件。

是的，多數異味是因為冷氣內部積水發霉或風輪堆積塵垢。這時需進行深層清洗，包含冷排與出風口葉片等部位。若清洗後仍有異味，建議請專業人員檢查。

是的，外機也需要定期清理。外機吸入空氣時若灰塵或落葉卡住散熱片，會影響冷氣整體效率。可以用刷子或吸塵器清潔外殼與散熱片周圍灰塵，保持良好通風。
