Mini Split Size Chart

The mini split size in BTUs required for a room depends on the size of the room, ranging from 6,000 BTUs for rooms between 150 to 250 sq ft to 36,000 BTUs for rooms between 1,400 to 1,500 sq ft.
Room Size (sq ft) Mini Split Size (BTUs)
150 to 250 sq ft 6,000 BTU
250 to 350 sq ft 9,000 BTU
350 to 450 sq ft 12,000 BTU
450 to 550 sq ft 15,000 BTU
550 to 700 sq ft 18,000 BTU
700 to 1,000 sq ft 24,000 BTU
1,000 to 1,200 sq ft 30,000 BTU
1,200 to 1,400 sq ft 34,000 BTU
1,400 to 1,500 sq ft 36,000 BTU

The Mini Split Size Chart provides a comprehensive guide for selecting the appropriate mini split size (measured in BTUs) based on the size of the room in square feet. The chart categorizes different room sizes and correlates them with the corresponding mini split size required for efficient cooling or heating. This information is essential for individuals or professionals looking to install mini split systems and ensures optimal comfort and energy efficiency. The chart provides a range of room sizes and their corresponding BTU requirements, making it easier to make informed decisions when choosing a mini split system for a particular space.


What is a mini split size chart?

A mini split size chart is a tool that provides guidance for selecting the appropriate size of a mini split air conditioning or heating system based on factors such as room size and climate conditions.

How do I use a mini split size chart?

To use a mini split size chart, you need to determine the square footage of the room or area you want to cool or heat. Then, refer to the chart to find the recommended BTU (British Thermal Units) capacity range based on the room size and climate conditions.

Why is it important to select the right mini split size?

Selecting the right mini split size is crucial for maximizing energy efficiency and comfort in your space. Choosing an undersized unit may result in inadequate cooling or heating, while an oversized unit can lead to inefficiency and higher energy consumption.

Are all mini split size charts the same?

Mini split size charts can vary slightly depending on the manufacturer or brand. While many charts are similar in terms of providing general guidelines, it's recommended to refer to the specific chart provided by the mini split system's manufacturer for the most accurate sizing information.

Can I rely solely on a mini split size chart for selecting the right unit?

While a mini split size chart is a helpful starting point, it's advisable to consult with a professional HVAC (Heating, Ventilation, and Air Conditioning) technician or contractor who can assess factors like insulation, sun exposure, occupancy, and unique room characteristics to ensure an accurate sizing calculation.
