This is the reason that room conditions also function in air conditioner performance

When you use conditioner water at home, you must always clean and maintain it properly. Because, if not treated and cleaned with money, the air conditioner can not function properly. At http://www.airconservicing.org/ you can get the cleaning and repair of the water in your questionnaire.

However, when the air conditioner you have is not functioning properly, there must be a cause. One of them is the condition of the room. Because the condition of the room can also be one of the causes of the air conditioner is not cold. If your room is available for sunlight to come then that room will be hotter. Then, if the room is made by cement, then the air conditioner will not run smoothly.
If you feel that the room cannot be cool as you want, then try to lower the air conditioner temperature or replace the air conditioner you have with a larger cooling capacity.
