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

What is a single zone mini split?

Mini split systems feature a single condenser, which sits outside the home, line sets and one or more air handlers inside. A single zone mini split has only one air handler, responsible for one zone (or room).

How many square feet does a mini split cool?

The coverage for a mini split AC system depends on its BTU rating. The greater the BTUs, the greater the coverage. You need approximately 30 to 60 BTUs for every square foot of area you wish to cover. For more information about sizing your system, visit our sizing guide.

Are mini splits expensive to run?

Energy efficiency is a substantial benefit to mini split systems. Due to the tight tolerances in the manufacturing process and reduced air loss in a ductless system, energy usage – and therefor electricity usage - is less than with conventional systems.

AC means more than cooling. A single zone mini split, equipped with a heat pump, can provide year-round comfort without interfering with the home’s overall HVAC system. A heat pump reverses the heat extraction process in winter, extracting heat from the atmosphere and forcing it indoors. Standard Heat Pump and a Split System Heat Pump.
