A quick buying guide

What should you look at before choosing?

A 9,000 BTU mini split is often the first size people look at for a small room, cabin, tiny home, shop, or trailer. Sometimes it is exactly right. Sometimes windows, air leaks, high ceilings, harsh weather, or frequent door openings push the load higher. Compare the complete systems below after you know what the space actually needs. Pay attention to the included line set, electrical requirements, operating range, installation space, and current availability—not just the number on the box.

Choose the size

What does the space actually need?

Square footage is a useful clue, but it misses your windows, insulation, air leaks, climate, and ceiling height. A heating and cooling load calculation considers those details and helps you choose the right size.
