Mini Split Zone Math

What is a Dual Zone Mini-Split System?

There are different types of Air Handler options to choose from including; Ceiling Cassette, Ceiling Suspended, Concealed Duct, Floor Mounted, Multi-Positional, or Wall Mounted. Each air handler is controlled separately by its own remote control. This way every room can be set to a different temperature if desired. This creates a miniature HVAC system that can be used to heat and/or cool up to two areas without using ductwork.

Sizing your new Dual Zone Mini Split (for BTU rating) is based on the square footage of the space you are wanting to heat or cool. Each air handler can have separate BTU rating based on each room’s dimensions. With two rooms, you will want to use the square footage of each room and size the two Air Handlers separately. The below chart is a rough estimate only. Have a professional installer give you a more accurate sizing for your specific situation.

Square footage = BTU Output

150 to 250 sq ft = 6,000 BTUs

250 to 300 sq ft = 7,000 BTUs

300 to 350 sq ft = 8,000 BTUs

350 to 400 sq ft = 9,000 BTUs

400 to 450 sq ft = 10,000 BTUs

450 to 550 sq ft = 12,000 BTUs

550 to 700 sq ft = 14,000 BTUs

700 to 1,000 sq ft = 18,000 BTUs

1,000 to 1,200 sq ft = 21,000 BTUs

1,200 to 1,400 sq ft = 23,000 BTUs

1,500 sq ft = 24,000 BTUs
