Fellow Zoni here, and a moon-lighting HVAC service tech. To clarify a common misconception, A/C refrigerant does not cool air even though that is the net result. It actually absorbs heat and releases it outside the strucure. Sorry for the pedantry, but if we come here to learn, may as well learn the technicals.

This is a distinction without a difference. Removing heat from the interior air is the same thing as cooling the interior air.

If you mean that the air conditioner doesn't produce a magical substance called "cool", that's true, but no one claimed that it does. The mechanism transfers heat with the effect of cooling the interior.

Just thought I would try to illuminate a prevalent technical misconception.

I get that, but he didn't make an incorrect or misleading claim. And honestly, most people on HN probably understand that air conditioners move heat.
