Protect household hygiene and prevent AC mould
Contents
Summer in Hong Kong is hot and humid, and the temperature difference between indoors and outdoors is large. Long hours of AC use can cause condensation to build up inside the unit. Without regular maintenance, mould can easily form inside and affect the indoor environment.
The rainy season in June and its impact on the inside of AC units
High humidity around June triggers mold growth in AC units.
- Moisture in the air turns into large amounts of condensate when the AC is operating.
- Hot and humid weather creates a sealed, damp and dark space inside the casing.
- This environment is extremely suitable for mould spores to multiply exponentially in a very short time.
- If there is a strong sour, musty smell as soon as the unit is turned on, it means mould has already taken over the inside.
Health risks to family members from a dirty air conditioner.
If an air conditioner is not cleaned for a long time, it may produce odours during operation, affecting indoor comfort.
- Mould drifting in the air can directly irritate the respiratory mucosa and cause persistent coughing.
- For family members with nasal allergies or respiratory sensitivity, symptoms may worsen in June.
- Even a small amount of allergen contact on the skin can easily trigger eczema and itching.
- Keeping the air outlet clean is the first line of defence for home hygiene in summer.
June must-know anti-mold tip: run fan mode before switching off
In view of the extremely humid weather around June, it is necessary to establish proper shutdown habits.
- It is recommended to switch to fan-only mode for the last thirty minutes before turning off the air conditioner each day.
- In fan mode, the compressor stops operating, but the fan continues to run.
- Continuous airflow can effectively dry the water accumulated on the cooling fins and drip tray.
- Keeping the inside of the unit dry can directly cut off the moisture source that mould relies on to survive in summer.
Simple daily AC care and dehumidifying in summer
Coordinating with other home cleaning methods can make mould prevention more effective.
- In June, when air conditioners are used frequently, the dust filter must be cleaned every two weeks.
- After washing, the filter should be left in a cool place to dry completely before reinstalling.
- If dehumidification is needed, first check the actual humidity and model functions; do not ask every household to run the air conditioner and dehumidifier at the same time just because it is raining heavily. Use equipment according to its own power supply and safety requirements. If there is flooding or suspected water ingress, do not risk switching it on just for dehumidification.
Find professional help
Although routine care can help prevent mould, during the hot and rainy month of June, dirt often penetrates deep into the squirrel-cage fan and heat sink fins, where ordinary household tools cannot remove it completely.
Seeking help from a professional team is a wise choice for restoring a healthy living environment. Professional AC cleaning companies are equipped with high-pressure washers and specialized disinfecting agents. Their technicians are strictly trained and can safely dismantle components and reach into gaps to break down deep mold without damaging parts. Entrusting deep cleaning to a professional team can extend appliance life and ensure clean airflow.
