LG LSXC22436S Side-by-Side Counter-Depth Refrigerator review: This might be the best side-by-side fridge I've tested

Temperatures remained just as accurate and consistent when we dialed the fridge down to its coldest setting.

What's really impressive about that is that LG gets you there while using about 20 percent less energy than its closest counter-depth side-by-side competitors. With an energy draw of 520 kWh, it'll add about $62 to your power bill each year. With most comparably sized side-by-sides, that number is a lot closer to $80.

On a related note, here's a quick efficiency tip: To get a good, relative sense of a refrigerator's efficiency, take the yearly energy cost and divide it by the fridge's total capacity in cubic feet. That'll give you the yearly cost of cooling each cubic foot in the fridge -- a helpful efficiency metric when you're comparing refrigerators of different sizes.

Anything less than $3.50 per cubic foot is a decent, below average number -- especially when paired with good performance. In the case of the LSXC22436S, that yearly cost per cubic foot is $2.83, which is one of the lowest, most efficient numbers I've seen from a full-size fridge. And, again, the performance is pristine.

That includes the coldest setting of 33 degrees. Over another 72-hour test, LG's side-by-side continued to deliver consistent, accurate temperatures that all averaged out to just above freezing, which is precisely what you want. Meanwhile, performance in the freezer stayed steady, hugging the target temperature of 0 degrees F nice and close, no matter what we set to fridge to.

The verdict

With essentially zero design departures from the side-by-sides that came before it, the LG LSXC22436S is not the most exciting fridge money can buy. It doesn't set itself apart with flashy features, and it won't do anything to give your kitchen a more distinctive appearance. The smart features -- even the voice integrations with Alexa and Google Assistant -- are, for the most part, snooze-worthy.

For a lot of folks, none of that matters nearly as much as performance and efficiency -- and on both fronts, this is a best-in-class appliance. At $2,099, it's also one of the least expensive counter-depth side-by-sides you can find. If you're willing to wait until later in the year when it isn't quite so new to the market, then there's a good chance you'll be able to find it for even less. But even at full price, this fridge is an outstanding value.
