> It's the SI unit, what else do you want to use lol? HVAC companies in the US exclusively use ‘tons’ to describe the amount of heat a chiller or heat pump can move. Trane, Daikin, and more all use ‘tons’ on both their marketing and engineering material. 1 ton ~= 3.56kW, but a 1-ton chiller will use ~= 1kW of electricity to remove 3.56kW of heat due to the COP of 3-4 for an air cooled chiller.
