Aircon BTU sizing calculator

Work out roughly what cooling capacity (BTU/h) your room needs before you talk to a contractor. This helps you avoid an undersized or oversized unit.

Recommended cooling capacity

8,000 BTU/h

This is a rough guide; a contractor will confirm exact capacity after checking ceiling height, windows and insulation.
