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.
Friedrich Air Conditioners
.webp)
Friedrich is one of the most respected names in U.S. air conditioning — and for good reason. Founded in 1883 in San Antonio, Texas, the brand has been crafting high-performance cooling systems since the 1950s, with a strong focus on institutional, hospitality, and premium residential applications. While they offer a broader lineup, Friedrich’s window air conditioners stand out for their build quality, quiet performance, and reliability. Their current window lineup includes three main series: the heavy-duty Kuhl®, the stylish and smart Chill® Premier, and the energy-efficient Chill® Premier Inverter. Unlike budget-focused brands, Friedrich builds for longevity — delivering quiet operation and commercial-grade components, even in residential settings. That said, the premium price tag and occasionally outdated app design can raise eyebrows. Let’s see where Friedrich justifies its cost — and where it needs to catch up.
