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. In case you were wondering, this unit puts out 8,000 BTU’s of cooling power so it is ideal for small and mid-size rooms. It has an 11.2 efficiency ratio rating from EnergyStar and it gives you the option of drawing in air from outside or indoors.
