So what do you reefers prefer or rather use, home A/C or chiller?. I just installed A/C for my home ending of last year so this is my first year to use it for summer. Last year I used my chiller but of course will exit out heat. Anyone that experience both which one is more cheaper to run? Or it doesn't really matter due to the fact that both will draw power about the same?! Who has actually paid attention to there bill and notice if there is a difference or not?
