[Home AC Temperature Guide] Older people feel cold, but younger people feel hot
Contents
When autumn arrives, it should be the most comfortable season for the whole family, but in Hong Kong homes the living room often becomes a battlefield over temperature. Younger family members return home sweaty after work or walking during the day and want the AC set to a cool 22°C; older family members, however, tend to feel the cold and may start aching after sitting for a while, even needing a blanket. This difference in how family members feel is especially noticeable when autumn weather swings between hot and cold. Many people think that simply turning the AC on and off during the season change is enough, but they overlook the fact that long-term uneven operation not only makes moisture and mould more likely to build up, but also worsens health issues and family friction.
Why does the AC make older people feel cold and younger people feel hot in autumn? The hidden conflict of different family perceptions
When the weather turns cool in autumn, Hong Kong families often face a classic problem: older people feel that the cool breeze makes their bones ache, while younger family members feel the room is too stuffy and want the temperature lowered again. This huge difference in how the family feels is actually due to differences in metabolism and blood circulation across age groups. Older people have a slower metabolism and are especially sensitive to changes in ambient temperature; direct cold air can easily trigger joint pain or respiratory discomfort. By contrast, younger people are more energetic, and after being affected by the humid and stuffy weather outdoors, they want strong air conditioning to cool down as soon as they get home.
If the home AC has long lacked proper maintenance, uneven airflow at the outlet can cause the living room to feel like two extremes at once — one corner freezing cold, while another remains unbearably stuffy. This can directly intensify daily friction among family members and affect the harmony of the home.
Always giving in by setting the temperature too high or running full blast? The dual harm of temperature imbalance to AC components and health
When dealing with different family needs, many households tend to compromise blindly, such as setting the AC temperature very high to accommodate the elderly, or running strong airflow all the time to suit younger family members. However, this often only treats the symptoms, not the root cause, and places a heavy burden on the AC unit. In Hong Kong's highly humid autumn climate, if the temperature is raised blindly while operating time is reduced, residual condensed water inside the unit cannot evaporate effectively, allowing mould and bacteria to grow quickly.
At the same time, if dust builds up in the air conditioner's filters and heat exchange fins for a long time, airflow circulation will be seriously obstructed and cooling efficiency will drop sharply. This will not only quietly increase electricity bills, but also allow mould spores to be blown throughout the home through the air supply system, creating an unseen health risk for elderly people and children with weaker immunity, and may trigger nasal allergies or coughing.
A family comfort showdown: how can air-conditioning adjustment and maintenance resolve household hot-and-cold conflicts?
To meet the very different comfort needs of family members of all ages, simply adjusting the temperature blindly is not enough. You need both scientific temperature setting and daily maintenance. To help vehicle owners and home users clearly understand how to balance the needs of the whole family, we have organised the key comparisons and response strategies into the following practical table:

Temperature setting range 🌡️
Keep the room temperature at 25 to 26°C to avoid feeling chilled to the bone
Use a circulating fan to help cool the room and improve comfort locally
Clean the filter and fan wheel regularly to ensure even airflow and no odours
Air direction and discharge angle 💨
Adjust the air deflector upward to avoid cold air blowing directly on the body
Turn on left-right wide-angle swing to speed up indoor air circulation
Check whether the swing motor and air guide vane operate smoothly
Humidity and air quality 💧
Reduce respiratory sensitivity triggered by dry, cold airflow
Reduce stuffiness and maintain a dry, cool environment
Carry out a deep autumn AC cleaning to remove mould and musty odours
Is adjusting the airflow yourself comprehensive enough? Identify the safe DIY fine-tuning range and the line to deep maintenance
When you notice that the air from your home air conditioner is not evenly distributed, or family members start arguing over the temperature, many people try adjusting the remote control themselves, moving the air direction flap, or removing and washing the simple plastic dust filter. At this point, it becomes especially important to clearly define the boundaries between safe DIY work and tasks that require professional expertise. Your safe DIY scope is mainly limited to setting an appropriate temperature with the remote control, using a circulation fan to improve indoor air flow, and regularly cleaning removable dust filters. However, never blindly dismantle internal components or force-clean the deep evaporator without professional tools. When the fan wheel inside the unit is full of dirt, the drain pan is clogged, or a mouldy smell is blowing out, these structural problems must be handled by a professional.

Frequently asked questions
Q1: In autumn, how should I set the AC temperature to suit both older adults and younger people?
A: It is recommended to set the AC temperature between 25 and 26 degrees Celsius and use it together with an air circulation fan. This can reduce the stuffy feeling for younger people without making elderly family members feel too cold.
Q2: Why is the temperature so different in different parts of the home when the AC is on? Is the AC broken?
A: This is usually because heavy dirt has built up on the internal blower wheel or heat-exchange fins, affecting airflow efficiency and air distribution. Deep cleaning is recommended to restore even airflow.
Q3: During the autumn changeover, besides cleaning the dust filter, what else can help improve indoor air and comfort?
A: In addition to regular cleaning of the dust filter, booking a professional AC cleaning service periodically to remove internal mould and moisture can effectively improve air freshness and reduce respiratory sensitivity.
