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?
Friedrich Air Conditioners
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 That said, the premium price tag and occasionally outdated app design can raise eyebrows.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.
