A correctly sized system isn’t just based on the size of the structure. Many factors go into determining the size of the system, including type of house and walls, type and size of windows, insulation, basement and attic conditions, house orientation etc.
When sizing air conditioners, be careful not to make the mistake of getting one that is too large. If the system is too large for the space, it will short cycle. In other words, the compressor will not run long enough to dehumidify the space and will limit your comfort. In addition, it will cycle on and off more frequently, increasing operating costs and reducing the system life. Proper air conditioner sizing is critical to optimize performance.
