The size of a mini split refers to its capacity or ability to condition a given area usually measured in BTUs.
Getting the wrong capacity can be a costly mistake. Even though mini splits use efficient inverter technology, you'll still need to make sure it will be able to handle the load requirements based on factors like: size and construction of your room, outdoor temperature range, etc.
If the system is too small, you'll find yourself wasting energy while your unit runs continuously, all the while failing to keep you comfortable in extreme conditions. This lack of performance will leave you on the hunt, yet again, for a better solution.
If the system is too large, you'll spend more on equipment and throw any energy savings out the window. Oversized equipment will also fail prematurely due to short cycling (turning on and off frequently).
