Using a commercial heating and a/c device is much more peculiar than using a residential heating and a/c. With a commercial heating and a/c device you have to be extra careful not to crank it so much. Otherwise you will find yourself and your corporation where you have it having super high energy bills! My buddy and I are talking about energy bills that could end up in the thousands in terms of cost! I had to learn this the difficult way when I first opened a corporation and had to get a commercial heating and a/c for it. My unquestionably first energy bill was close to one thousand dollars! I had never seen an energy bill that high in my whole entire lifetime! It was then that I learned the ways of using a commercial heating and a/c unit. You do not need to crank the heating or the air conditioner the same as you would at a condo with a residential heating and a/c. Because commercial heating and a/c units are much more powerful and can heat plus cool your building in a lot less time. So you do not have to crank the thermostat that much. Your building will be the right temperature if you set it where it needs to be and all will run smoothly. This is how I do it now and ever since I no longer have those bank splitting energy bills for the office building that I own!
