The Latest 18000 BTU Window Air Conditioners 2024

Our list of the newest 18000 BTU window air conditioners includes only air conditioners that obey to these rules:
  • Being 18000 BTU rated and designed to fit windows (May include some closely-rated 19000 BTU models). Most 18000 BTU window air conditioners require a 230-240V power outlet -- if that's not a possibility for you, consider installing two 120V 10,000 BTU Acs in different parts of your home.
