how to evaluate the performance of air conditioning

[vinhphysics]

Hello all,
We would like to build a system in order to evaluate the performance of air-conditioning. Who can help us to disign this system or introduce the company where we can consult?
thank you!

Have you tried contacting some engineering consulting firms in your area? There should be some with HVAC experience who would fit your requirements well.

I'm not sure what you mean by "build a system". You can take standard measurement tools and measure the performance directly.
