How do I know what size split system I need?
First, calculate the floor area of the room you are going to be heating. Measure the length and width of this space, and multiply them to get the metres squared (m2).
Depending on your ceiling height, you will need to calculate your floor space by the watts below:
- 2.4m = 150 (watts)
- 2.7m = 160 (watts)
- 3m = 175 (watts)

A mini-split can have a rating of as low as 6,000 BTUs to as high as 56,000 BTU.
Do mini splits use a lot of electricity?
Ductless mini split systems are extremely efficient. Compared to conventional room air conditioners like window units and portable ACs, using a ductless mini split cooling system can cut energy costs by 30 percent.
Should I run my mini split 24 7?
A mini-split system uses less energy and keeps temperatures most consistent when it runs continuously, as in, 24/7. You also don’t need to turn the units on and off or adjust temperature settings when you’re away like you might with a central heating and cooling system controlled with a thermostat. Set the fan to AUTO.
