Choosing the Right Size

Choosing the right size for your Mitsubishi mini split is crucial for optimal performance and efficiency. A unit that's too small won't provide adequate temperatures, while an oversized system cycles on/off inefficiently.
You can use Mitsubishi's sizing calculator to match your room's dimensions, window area, climate, usage, and more. This calculator will give you an estimate of the size needed for your application.
For well-insulated residential homes, about 15-20 BTU per square foot is usually sufficient for a Mitsubishi mini split. For the top floor in a multi-story home, about 25-30 BTU per square foot is required.
Standard office spaces with an average number of occupants and office equipment will require around 35-40 BTU's per square foot for their Mitsubishi AC. This can be reduced by about 20% if there are no outside exposed exterior walls.
Mitsubishi's sizing calculator makes it easy to determine the right size for your space. It's worth noting that bedrooms need less capacity depending on occupancy and shading.
