Toronto is characterized by cold winter but summer may be a bit warm. Besides, the rising global temperature has made Toronto and several other Canadian cities warmer than before. The year 2017 was designated the warmest year since the 1800. The extreme weather events in summer call for the use of adequate air conditioners to cool and maintain the room temperature to normal. But the question is: what size of air conditioner should you go for? Since you need to really cool your room during winter, is it advisable to go for a bigger sized air conditioner to cool faster? Or should you just go for a smaller sized air conditioner to save cost?
Go for Optimal Size
The two extremes will make things worse. You will end up spending more if you go for relatively bigger or smaller sized air conditioner with respect to your room size. The misconception that “the bigger is always the better” is wrong.
A bigger sized air conditioner will definitely cool your room faster but that’s not the entire story. An air conditioner is designed to serve two main purposes which include dehumidifying and cooling a space. A relatively bigger sized air conditioner only cools the space but will not remove moisture or dehumidify it. This makes the cool air damp and therefore making people within the space uncomfortable.
A relatively smaller sized air conditioner will not effectively cool the air in the space. It lags in one of the functions of an air conditioner and therefore not effective. In addition, a smaller sized air conditioner will cost more to run because it will consume higher amount of power.
To cut down cost, cool your rooms faster and also dehumidify the space appropriately, you need to go for the optimal sized air conditioner for your space.
Air conditioner size for your 900 square feet room
There are various charts to determine the appropriate size of air conditioner for your space. However, one of the ways to calculate the appropriate size of air conditioner for your space is to determine the area of your space in square feet and multiply the obtained area by 25 BTU.
Going by this calculating, the appropriate air conditioner size for your 900 square feet room will be 22500 BTU per hour. The result is a bit different (although close) from the value given in some available charts. The recommended air conditioner size for a 900 square feet room is 18,000 BTU per hour.
However, it is important to note that, in some cases, environmental issues affect the air conditioner size that will adequately cool a space or a room. Thus, it is recommended that the aforementioned air conditioner size should be increased by 10 percent in a very sunny room and decreased proportionally in a shady room. Also, the number of people living in the room determines the size of the air conditioner needed to cool the room. The air conditioner size should be increased if more than two people live in the room.
