      Questions

      Common questions3
      What is the best window air conditioner brand?
      Among the 31 brands with at least three certified window models, Whirlpool has the highest median efficiency (16.0 CEER across 18 models). Midea has the most certified models (40). The best single model is not always from the best brand, so compare models of your size: the ranked list is on the window air conditioner page.
      Are window air conditioner brands really different?
      Less than the names suggest. 45 of the 145 certified units are sold under more than one brand name with identical ratings and dimensions, so two brands often mean the same unit in different packaging. The certified data cannot say how loud a unit is or how long it lasts; it measures efficiency and capacity.
      Which window air conditioner brands should I avoid?
      We rank on certified efficiency, not on reliability or service, because the public data has no failure rates. A low-efficiency model costs more to run every year; the models at the bottom of each size list are the ones to skip on running cost alone. For reliability, read the warranty terms and recent owner reviews.
