How Do I Choose the Right Size for a Mini Split?

The size of the mini split depends on the room's dimensions and specific needs. For example: • A 400-square-foot room typically requires a 9000 BTU mini split. • A 550-square-foot room needs 12000 BTUs. • A 1000-square-foot room needs 18000 BTUs. • A 1500-square-foot room needs 23000 BTUs.

Can I get longer extensions for this installation kit?

Yes, you can purchase a longer lineset separately. Please note, if the extended lineset is longer than 25 feet, additional refrigerant will be required. Make sure to consult a professional HVAC technician for proper installation.
