If the ceiling fan has been used for about one year, check whether all parts of the ceiling fan, such as the suspender, screws, wiring base, blades, etc., are loose or corroded, rusted, cracked, deformed, etc., whether the connection of all parts of the suspender and the hook are firm, and whether the force is good. If there are loose screws, tighten them in time, and replace the damaged parts in time. In addition, check the wear of screws and pin shafts every 2-3 years, and replace them in time in case of serious wear.

With the trend of global warming and environmental protection and energy conservation, the use of air conditioners, which are high power consuming appliances, is increasingly restricted. One air conditioner is equivalent to the power consumption of 20 ceiling fans. When the temperature is not more than 30 degrees, using fans can completely achieve the effect of cooling and heat removal. Among all fans, only ceiling fans produce the largest air volume at the same power, so ceiling fans are recommended in the United States.
