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 DIY Mini-Splits, any room can be tailored to fit your lifestyle and needs.
Start by Selecting Zone One:
9K BTU for 250 - 400sq ft (typically a small shed, or single car garage)
12K BTU for 400 - 600sq ft (typically a sunroom, or standard garage)
15/18K BTU for 600 - 1,000sq ft (typically a studio apartment)
MRCOOL's Quick-Connect® Pre-Charged Line Set

Quicker Installation than Conventional Line Sets
