Common questions

What size split system do I need?

Roughly 1kW of cooling per 10 square metres of well-insulated space: a 2.5kW unit suits a bedroom, 5kW a living area, 7 to 9kW for open plan spaces.

What is a back-to-back installation?

The indoor and outdoor units sit on opposite sides of the same wall with a short pipe run. It is the cheapest install; every extra metre of piping adds cost.
