Many of us got the wrong idea, to my thinking..

Regardless what brand you use, a 24C is always 24C..

There is no such thing xx 24C is cooler than yy 24C

I think what matter most in the selection of aircond is the cooling capacity..

Consider everything from heat load, external heat etc and get the right cooling capacity..

That way you wont overprovide or underdesigned your AC
