Best Window Air Conditioners of 2026: Midea, Zafro, GE

2026年最佳窗式空调：Midea、Zafro、GE

The world is getting warmer. And the weather is getting weirder. Air conditioning isn’t the answer, but it does help: Extreme heat is exhausting, and it ages you faster than smoking or drinking. The best window air conditioners—like our top pick, Midea’s 8,000 BTU U-Shaped Smart Inverter Window Air Conditioner ($400)—offer sweet relief. This Midea model also has a smart design that still lets you open your window.

世界正在变暖，天气也变得越来越反常。空调虽然不是解决气候问题的根本办法，但确实有所帮助：极端高温令人疲惫，其对身体的衰老影响甚至超过了吸烟或饮酒。最好的窗式空调——比如我们的首选产品，美的（Midea）8,000 BTU U型智能变频窗式空调（400美元）——能为你带来舒适的凉爽。这款美的机型还拥有巧妙的设计，让你在安装后依然可以打开窗户。

Like our other favorite window and portable cooling units, the Midea is among the most energy-efficient on the market, and uses newfangled coolants that don’t deplete the ozone like the more damaging ones of yore. Heat pumps are even more efficient, and minisplits like the Della Optima Series 12,000 BTU 23 SEER2 ($970) are becoming increasingly accessible although they require expensive installation.

与我们喜爱的其他窗式和移动空调一样，美的这款产品是市场上最节能的机型之一，并且使用了新型制冷剂，不会像过去那些有害物质那样破坏臭氧层。热泵的效率更高，像Della Optima系列12,000 BTU 23 SEER2（970美元）这样的分体式空调正变得越来越普及，尽管它们需要昂贵的安装费用。

We’ve also included the best models for those on a tight budget, such a surprisingly quiet small-room 5,000 BTU air conditioner from GE for a mere $164. But note that budget models generally aren’t as efficient, so saving on upfront cost can lead to higher energy bills over time.

我们还为预算有限的用户精选了最佳机型，例如GE一款仅需164美元、运行起来出奇安静的5,000 BTU小空间空调。但请注意，经济型机型通常效率较低，因此节省初期购买成本可能会导致日后更高的电费支出。

2026年5月更新：我们增加了Della Optima系列12,000 BTU 23 SEER2作为热泵选项，以及新升级的Zafro双管移动智能变频空调。我们还移除了已停产的型号和品牌（如July），精简了推荐列表，并更新了全文的链接和价格。

Best Overall Window Air Conditioner: Midea U-Shaped Air Conditioner

最佳整体窗式空调：美的（Midea）U型空调

Surprise: A window air conditioner that actually lets you open the window. Midea’s U-shaped AC comes with a bracket that balances the unit’s weight by leaning against the exterior wall of your home, so you can open the window without worrying your AC will fall out. The big notch between the front and back also lets you pull down your window deep into the unit, leading to less of an air gap and better efficiency. (It’s also nice for soundproofing, noted WIRED senior editor Julian Chokkattu.) Foam padding is included to help seal off the small remaining gap.

惊喜：这是一款真正能让你打开窗户的窗式空调。美的U型空调配有一个支架，通过抵住房屋外墙来平衡机身重量，因此你可以在不担心空调掉落的情况下打开窗户。机身前后之间的大凹槽还能让你将窗户深深地拉入机身内，从而减少缝隙，提高效率。（WIRED高级编辑Julian Chokkattu指出，这对于隔音效果也很有帮助。）包装内附带泡沫垫，有助于密封剩余的小缝隙。

This U-shaped AC remains WIRED’s favorite after substantial fixes following a voluntary recall last year over worries about mold formation in the fan—largely due to less than ideal installation. The 2026 version includes a redesigned drain plug and seals, easier cleaning access, and bubble levels to ensure the unit is tilted appropriately to drain. I’ve received the newest model with the fixes, and am keeping an eye out for any condensation. I’m also testing the Midea’s newest Inverter Plus line.

在去年因担心风扇内霉菌形成（主要由于安装不当）而进行自愿召回并进行重大修复后，这款U型空调依然是WIRED的最爱。2026年版本包括重新设计的排水塞和密封件、更易于清洁的入口，以及确保机身倾斜角度适宜排水的水平仪。我已经收到了带有修复功能的最新型号，并正在密切关注是否有冷凝水产生。同时，我还在测试美的最新的Inverter Plus系列。

For now, no other unit matches this unit’s mix of convenience, performance, quietude, and energy-efficiency. Because most of the AC’s components are housed outside the window, this AC is among the quietest we’ve tested. It cools quickly, and is among the most energy efficient on the market. The AC connects to Google Assistant and Amazon Alexa, meaning you can turn it on remotely before you get home, and has an app that tells you when to replace the filter. It also performs exceptionally well with minimal maintenance, according to reviewer Lisa Wood Shapiro’s long-term testing. Just note that this video from the company is more helpful than the printed instructions when it comes to installation.

目前，还没有其他机型能在便利性、性能、静音和能效方面与这款产品相媲美。由于空调的大部分组件都安装在窗外，它是我们测试过的最安静的空调之一。它制冷迅速，且是市场上最节能的机型之一。该空调支持Google Assistant和Amazon Alexa，这意味着你可以在回家前远程开启它，配套的应用程序还会提醒你何时更换滤网。根据评测员Lisa Wood Shapiro的长期测试，它在极少维护的情况下表现依然出色。只需注意，在安装方面，公司提供的视频比纸质说明书更有帮助。

Best Portable Air Conditioner: Zafro Smart Inverter Portable Air Conditioner

最佳移动空调：Zafro智能变频移动空调

Enter the Zafro Smart Inverter, a powerful portable AC that uses two duct hoses fed into an adjustable panel that slides into your window frame. That design makes this device incredibly flexible for weird windows, and would have saved my ex-wife two days of carpentry when custom-building a frame for the horizontal sliding windows we had in an ’80s-built home out West. Push the power button, and the two vents on the top open to direct air around your room.

隆重介绍Zafro智能变频空调，这是一款功能强大的移动空调，它使用两根导风管连接到一个可调节的面板上，该面板可滑入窗框。这种设计使该设备对于异形窗户具有极高的灵活性。如果当年我们在西部80年代建造的房子里使用它，我前妻就不必花两天时间为水平推拉窗定制框架了。按下电源键，顶部的两个出风口会自动打开，将冷气吹向房间各处。

In a month of testing, I’ve found the Zafro delivers the performance and flexibility you’d expect at this price. The model I tested offered an impressive 16,000 BTUs of cooling, more than enough to quickly cool the approximately 400 square feet where I’m using it. There’s a system for ejecting condensed water automatically, which works in all but extreme humidity, which I have not yet encountered. In addition to a full suite of buttons on top and an included remote, the device connects via Wi-Fi to an app that allows you to set the temperature and pick between modes (eco, humidity reduction, fan, and a super-powerful extra mode).

在一个月的测试中，我发现Zafro提供了该价位应有的性能和灵活性。我测试的型号拥有令人印象深刻的16,000 BTU制冷量，足以快速冷却我使用的约400平方英尺（约37平方米）的空间。它配备了自动排出冷凝水的系统，除了极端潮湿环境（我尚未遇到）外，该系统在各种情况下都能正常工作。除了机身顶部的全套按钮和附带的遥控器外，该设备还可通过Wi-Fi连接到应用程序，让你设置温度并选择模式（节能、除湿、送风以及超强力模式）。
