GE Air Conditioners
GE has long been a staple of American homes — from lightbulbs to laundry machines. Its air conditioning division, now operated by Haier since 2016, has evolved considerably in recent years, blending classic durability with a growing emphasis on smart features and design flexibility. GE’s air conditioners are most commonly seen in window-mounted or built-in wall formats, often aimed at users who want solid cooling and low noise without fuss. That said, while the product line has modernized, GE is still more about refined practicality than cutting-edge innovation. So where does it land in the current AC landscape?
Keystone Air Conditioners
Keystone isn’t a brand that makes headlines — and that’s exactly its appeal. Often overshadowed by glossier competitors, it fills a critical role in the AC market: reliable, basic units that won’t drain your bank account. Keystone’s lineup includes a healthy variety of window units, a few through-the-wall options, and even dehumidifiers, all priced well below premium brands. You won’t find advanced features or connected apps here — just cold air, simple controls, and surprising performance-per-dollar. So, if you’re okay trading flair for function, Keystone might be your best-kept secret.
