Industry data shows that 70% of air conditioning failures are caused by improper maintenance, and common misconceptions are concentrated in three aspects.
Industry data shows that 70% of air conditioning failures are caused by improper maintenance, and common misconceptions are concentrated in three aspects. One reason is that the filter screen is not cleaned in a timely manner. Household air conditioning filters need to be cleaned every 2-3 weeks. Long term lack of cleaning can lead to a 30% reduction in air intake, a 25% decrease in cooling efficiency, and the growth of mold, which can cause respiratory problems. Secondly, the maintenance of the external unit is neglected. Dust accumulation on the cooling fins of the external unit will increase the load on the compressor, and overheating protection is prone to occur during high temperatures in summer. It is necessary to use a high-pressure water gun to flush it every month (avoiding electrical components).
Thirdly, extreme temperature settings, such as setting the temperature below 24 ℃ in summer or above 26 ℃ in winter, can increase energy consumption by more than 50% and easily cause air conditioning problems. The correct maintenance practices include: replacing the filter screen and cleaning the evaporator before starting up each year; Run the machine for 30 minutes to prevent moisture when not in use for a long time; When used in conjunction with curtains to reduce sun exposure, energy consumption can be reduced by 10% -15%. In addition, the installation location also affects efficiency. Outdoor units should be kept away from heat sources, and indoor units should avoid direct blowing on the human body. These details can extend the lifespan of the equipment by 3-5 years.
