Where reviewers disagree Noise is the split. Good Housekeeping calls the Windmill 'one of the quietest ACs we tested' but published no numeric measurement, while Wirecutter lab-measured ~46 dB average (40-50 dB range) and rates it 'slightly louder' than its Midea, Hisense, and Frigidaire top picks. Wirecutter is the exact-model, instrumented source; Good Housekeeping's verdict is qualitative and covers the Windmill inverter line broadly.

Noise, WhisperTech fan (average): ~46 dB (measured range 40-50 dB) · Compressor rumble frequency peaks: 2,000 Hz and 8,000 Hz

This Windmill model was easier to install than any other AC we’ve tested.

In our tests, we measured the Windmill’s WhisperTech fan as between 40 and 50 decibels, with an average noise of around 46 decibels.

You can’t change the direction of the fan. The Windmill AC sends air out at a 45-degree angle from the top and upper sides of the unit.

Good Housekeeping lab-tested · 2026-05-28

Based on our extensive testing, I can confirm that the Windmill is not only one of the most stylish window air conditioners on the market, but also one of the best performers.

It took about 15 minutes to get everything situated securely in the window.

All that design and innovation comes at a cost, with the Windmill priced higher than many comparable units.
