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 get one that is too large. If the system is too large for the space, it will cycle on and off more frequently, increasing operating costs and reducing the system life. Also, the compressor will not run long enough to dehumidify the space and will limit your comfort. Experienced Evolved Mechanical technician will visit your house and take detailed measurements and notes while conducting the survey to suggest the A/C system that best fits your needs.
