Two-way air conditioners are widely used by many families for cooling in summer and heating in winter. However, many users still do not know how to use the air conditioner in heating mode correctly to ensure health safety and save energy. In addition to choosing a machine with suitable power for the room size, you also need to pay attention to the following issues.
1. Only set the temperature difference to 5-7 degrees Celsius
Many people who use air conditioners for heating have the habit of setting the highest temperature with the desire to warm up quickly. This significantly affects both the operation process and the health of the users in the room.
Specifically, when stepping from the cold outside into the room, if there is a large temperature difference, it will cause thermal shock, and even fainting. Therefore, you should only set the temperature of the air conditioner to a maximum of 5-7 degrees Celsius higher than the outside temperature, without setting it too different. This temperature range helps users feel comfortably warm without experiencing thermal shock when entering from outside.


The chilly weather makes many people reluctant to leave their rooms and keep the heater on 24/7. However, this habit is not advisable, and you should not overuse the air conditioner. Instead of keeping it on all day long, consider turning off the air conditioner and opening the room door when the sun is shining warmly.
Even for young children, lying under the heater all day is completely discouraged. According to health experts, the maximum time for children to use the air conditioner should not exceed 2 hours each time. After 2 hours, let the children spend normal temperature time outside for about 15-20 minutes. Before letting the children out, open the door wide for about 2-3 minutes to let them acclimate to the outside temperature.

4. Utilize a humidifier when using the air conditioner
When using the air conditioner in winter or summer, it's also advisable to use a humidifier to prevent the humidity from dropping too low. If you don't have a humidifier, you can place a tray of water with wet towels hanging indoors to maintain humidity above 50%.
Additionally, when using the heating function of the two-way air conditioner, you can also turn on a room fan to circulate the air. However, you should only turn on the fan occasionally because frequent use can lead to heat loss.

Above are 4 tips for using a two-way air conditioner in winter to ensure health safety and save electricity, reducing monthly electricity costs. Hope they will be useful for you!
