**size**your

**mini split**correctly, you will need to know the square footage of the room, and check it against our table. For multi-zone systems, you will need individual air handlers for each room, with the specified BTU. Take the total BTU of the indoor heads, to establish the total outdoor capacity needed.

Besides, how do you size a mini split system?

To get a general estimate of **ductless sizing**, follow these 3 steps Calculate the square footage of the room by multiplying its **length** by its width. Multiply the area by 25. This answer is the approximate British Thermal Unit (BTU) output you need for that room, which is how **ductless** heat pumps are sized.

Secondly, how many square feet does a 1 ton mini split cool? 300-500 **Sq Feet** a 12000 Btu **1 Ton Mini Ductless Split** Air Conditioner would be best for you. **may** be best for you.

Also, how do I know what size split system I need?

Using a **formula to calculate** your **air conditioning needs** You will need to find the **length** and width of each room and multiply them. Then, you have to add the area of each room together for the total. This figure **needs** to be in square metres.

How many BTU do I need for a 12x12 room?

2. Find the correct cooling capacity for your room size

Area To Be Cooled (square feet) | Capacity Needed (BTUs per hour) |
---|---|

100 up to 150 | 5,000 |

150 up to 250 | 6,000 |

250 up to 300 | 7,000 |

300 up to 350 | 8,000 |
