No Two Rooms Are The Same...
Even if you have two rooms that are the same square footage, the room may need a larger or smaller BTU capability. Factors such as location, humidity, insulation, windows, ceiling height, or even room hotspots are just some of the things that can change the efficiency of your mini-split system and should be taken into consideration before purchasing.
Luckily with MRCOOL Single Zone Mini-Splits, any room can be tailored to fit your lifestyle and needs.
