Mini Split Zone Math

Mini split system air handlers come in the following types: Wall Mounted, Ceiling Cassette, Ceiling Suspended, Concealed Duct, Floor Mounted, and Multi-Positional. Each Air Handler is controlled separately by their own remote control giving you full control over each room’s heating and cooling systems. The air handlers can be set up in separate rooms or on opposite sides/floors of a large area (warehouse). The only alterations to the building will be small holes in the wall for the line sets, a pad put in place for the outdoor unit and four wall brackets installed onto the inside wall. All necessary accessories are on each product listing for your convenience.

To size your new 4 Zone Mini Split in order to determine the BTU rating for each air handler, use the square footage for each separate space. This allows you to have customized climate control in each room. Use the below chart for estimating only and consult a professional to get your exact needs.

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
