Hi everyone I've lived in "hot" and "cold" countries and the a/c systems installed in the homes are desgined to either "cool down" or "warm up" the house. So take the heater for instance. There is a 10 degree mark on the dial. Now 10 degrees is pretty cold. So what is stopping me from turning my heater into a cooler? For that matter, what is stopping me from cranking my cooler up to 35 degrees and get a heater out of it? There must be something wrong with my understanding of A/Cs but on the heater.. it DOES say 10 degrees... and 10 is cold! Any help will be appreciated. Thanks.
