Best Thru The Wall Air Conditioner Reviews

For us, noise can be a deal-breaker. Window and wall mounted units have a reputation for being noisy but the Friedrich Air Conditioning Co. CP08G10B is one of the quietest thru wall units we have ever encountered. We installed it in a room that is roughly 400 square feet and it sounded like a unit that was much less powerful in terms of BTU’s.

As the name suggests, the Koldfront WTC8001W is capable of 8,000 BTU cooling for rooms between 300 and 350 square feet. This model also has a dehumidifier function that is capable of removing 45 pints of airborne moisture a day.
