What should I compare between mini-splits?

SEER2 (cooling efficiency), HSPF2 (heating efficiency), cold-climate output at low temperatures, sound level, warranty, DIY-vs-pro install, and price. Matching BTU capacity to your room comes first - a bigger unit is not a better one if it is oversized for the space.

How do I pick between two mini-splits with the same BTU?

Look past capacity to efficiency and cold-climate performance, then weigh warranty, noise, and install path against price. If you heat in a cold climate, the low-temperature heating output is often the deciding factor. Our model pages score each of these so the trade-off is clear.

How to compare mini-splits the right way

Two mini-splits can look identical on price and BTU and still be very different systems. When you put them side by side, the numbers that actually separate them are cooling efficiency (SEER2), heating efficiency (HSPF2), how much heat they hold at low outdoor temperatures (cold-climate rating), sound level, warranty length, and whether they are DIY-friendly or professional-install only.

This tool lines up two to four systems on those quick facts so you are comparing what matters, not just the sticker. For the deeper story - our take on each, where it wins, and who it is for - open the model pages or our written head-to-head comparisons.
