What's wrong with air conditioning and cooling

1.The air conditioner lacks freon. Under such circumstances, the air conditioner cooling effect will be poor. 2. If there is a lot of dust and dirt in the filter, it will affect the heat dissipation effect, which will affect the cooling. 3. The outdoor temperature is too high, and it is difficult to lower the temperature by turning on the air conditioner at home. 4. Voltage problem, the power supply voltage of normal air conditioner is 220V, but if it is lower than 220V, the cooling effect will be greatly affected. Summer is coming soon, and the weather is getting hotter. But if the cooling effect of the air conditioner is not good after turning on, what is going on? Is there any good solution? <img src="{{media url=&quot;magefan_blog/What_s_wrong_with_air_conditioning_and_cooling.jpg&quot;}}" alt="" />
