I have my games in a 20x24 attached garage. I have 9 pins, two arcade/video games and a dual Daytona driver. I had a guy come and look at the garage to give me an estimate on installing a split unit for heating and ac as I now use a window unit and floor heater which don't do the job. He gave me an estimate of a one ton split based on the size of the room. I told him that it gets really hot with all the machines on and up to 20 people in the room. He said maybe you should bump up to a 1.5 ton. At that point, he was just guessing. This morning he called and said he needs the amperage and voltage for each game so he can add them to the calculation of how much cooling/heating power I need. I have looked for these numbers, but I'm not sure where to find them or exactly what I need to give him. Looking for input on what numbers to give him or advice as to what other people have use with success.
