Windmill Air Conditioners

Windmill is one of the youngest — and boldest — names in the air conditioner market. Launched by a team of New York natives, the brand set out to fix everything people hate about traditional window units: ugly boxes, loud fans, and headache-inducing installations. Their flagship product is a sleek, whisper-quiet window AC with Wi-Fi control, eco-conscious packaging, and an interface so minimalist it could pass for a Sonos speaker. But for all its design chops, Windmill is still a niche player with limited muscle — so let’s see where its sleek simplicity shines, and where it’s not quite ready for primetime.

BLACK+DECKER Air Conditioners

Black+Decker is a household name in the U.S., but traditionally in power tools and small appliances — not air conditioning. Over the last decade, however, the company has carved out a space in the AC market by licensing its brand to OEM partners who manufacture budget-friendly cooling units, particularly for short-term use. While their portable ACs are better known, Black+Decker also offers a trio of window air conditioner series: the digitally controlled BWAC series, the simplified BD series, and the basic BD-M mechanical dial line. All are designed for ease of use and mass affordability, and while they look solid on paper, the real test is in performance and longevity. So — is the rugged branding just a sticker, or does it hold up in the heat?
