Keep in mind

The duty cycle approximates how often the compressor draws the entered power.

Actual inverter AC use changes with set point, weather and room heat gain.

How this estimate works

A simple formula, visible assumptions

Energy = tonnage × watts/ton × hours × days × duty cycle.

The result updates in your browser as you change an input. It is a planning estimate, so compare it with real bills, product specifications and a qualified professional's assessment.
