OUR TOP PICKS
The earth is gradually warming up as a consequence of global warming. The summers are unbearable, and even the winters are not so warm. Offices around the world don’t want employees who come in sweating to stay tired throughout the day.
Air conditioners are a good solution to the scorching weather in both households as well as public places like shopping malls or restaurants. In this article, we will discuss about the best air conditioners that can be fitted in windows.
Before we buy an air conditioner, the following factors should be taken into consideration.
Factors to Look for While Buying the Best Window ACs
1) Cooling Capacity
The capacity for cooling is normally measured in BTU (British Thermal Unit). While selecting an air conditioner, choose the one which fits in the space. If a large area is to be air-conditioned, then the cooling capacity should be higher. An AC with little BTU power for a larger space will end up consuming a lot of power and will thus lead to a waste of energy.
Similarly, if the air conditioner has too much power for a small space, the dehumidification process will be messed up. The air conditioner will give an uneven cooling effect. To measure this, the size of the room will be taken into consideration.
Other factors to be regarded are the amount of sunlight that enters the room, the number of people in the room, and ceiling height. The room in which the air conditioner is also installed matters. For example, a kitchen might need an air conditioner with more power when compared to a bedroom.
Though this article will discuss only window air conditioners, there is another option of air conditioners called wall air-conditioners. As their names suggest, a window AC can be fixed in a window and a wall air-conditioner in a wall. For a window AC, the width and height of the window must be examined before installation. Installation kits will be useful for both the type of air conditioners.
3) Electrical Requirements
Air conditioners consume a decent amount of electricity and a large amount of power. Depending on the cooling capacity of the air conditioner, the electricity need will also increase. For an AC with 15,000 BTU or below cooling capacity, the voltage required will be 125 volts. It would increase with the increase in cooling capacity.
Energy Conservation- Air conditioners with energy star rating will reduce consumption by at least ten percent. These products will have special features which ensure energy is saved that the AC is long lasting.
Maintenance- The parts of the system must be cleaned periodically for the long life of the product. Parts like dust filter and condenser must be cleaned regularly to avoid clogging. This, in turn, will increase the effectiveness of the product. Most of the air filters will be washable with soap and water. Instructions on how to clean each part will be specified in the manual.
