Electrical Panel

What are the differences between a group of three phase power and single phase?

My electrician told me that I need a new phase of three panels to replace a single panel phase, but I have my doubts. What are the fundamental differences? I suspect that my panel "Single" phase can phase power because it seems that a three-phase HVAC unit is being provided by this panel.

What makes you think that your board "single" phase can provide 3 phase? Where are you? Different rules apply to different countries. If you are in Australia, the United Kingdom or certain parts of Europe, you should see (clearly) 3 different colored cables feeding the table main distribution, so it is 3 phases. In Australia, the colors are red (phase A), white (phase B) and blue (phase C). The neutral conductor shall be black. If you have the misfortune to be in the United States, you can see a multitude of cables white with a red (maybe) and perhaps a black or 2. If you are United States, I'd get an electrician.
