Best Large Window Air Conditioners (≥14,000 BTU) 2026
A big, open room needs real cooling power. These are window units of 14,000 BTU and up — enough for great rooms and open-plan spaces of roughly 700 square feet or more (20 BTU per square foot). Many draw more than a standard outlet supplies, so check the voltage. We rank the 87 qualifying units by CEER, then cooling BTU.

How the ranking works. We rank room air conditioners on CEER (Combined Energy Efficiency Ratio — the DOE test number), then cooling BTU. CEER is a certified metric, not a marketing term. Certification and specs come from ENERGY STAR and the DOE compliance database; running cost and suggested room size are computed by us from published ratings and EIA U.S. average electricity prices. Suggested room size uses the common 20-BTU-per-square-foot rule — sunny rooms and kitchens need more. Identical units sold under several brand names are collapsed to one row. No star ratings, no paid placement. These are self-install units; our buy links open a tagged Amazon search. See methodology.
