MiniSplit Facts

Ductless mini-splits sold online, compared

Who really makes it, what it's certified to do, and whether you can install it yourself.

Most mini-split brands sold online don't build their own units, many round their efficiency figures up, and few say plainly what a self-install does to the warranty. MiniSplit Facts reads each system's ENERGY STAR certification, the brand's own spec sheets and warranty terms, and the stores' prices, and lines up 410 systems from 9 brands, every figure with its source.

Install it yourself?

By the brands' own warranty terms, 145 of the systems we list keep their warranty when the owner installs them; 256 need a licensed technician or the warranty is void. Each product page quotes the terms and the date we read them.

Certified, not marketed

Efficiency and cold-weather figures come from the certification record of the exact indoor and outdoor pair. 20 times so far, a brand's own page states a figure differently from its certificate; we show the certified one and record the other.
