It just might be time to buy an air conditioner. Your next question will be, which one? Which type? Don’t fret, because we expected such questions already.
There are two main types of air conditioners; central air conditioners, and window air conditioners. A central air conditioner will cool down your whole house, while a window one will cool just one room. For the sake of this review, we will consider window-mounted air conditioners.
BTU, energy efficiency rating, size, cost, and noise level are factors that will influence what you buy.
- 1,050 – 1,600 sq. ft: 18,500 – 25,000 BTU
- 550 – 1,050 sq. ft: 12,000 – 18,500 BTU
- 350 – 550 sq. ft: 8,000 – 12,000 BTU
- 150 – 350 sq. ft: 5,000 – 8,000 BTU
Above is the BTU rating most fit for the room sizes listed.
Note: The higher the BTU, the more energy consumed, and the better the air conditioner. BTU = British Thermal Unit.
