Explanation in the comments:

$Var = "HvacSystem8000Series";
$Var =~ s/(?<=[[:lower:]])   # Low case before,
          (?=[[:upper:]0-9]) # upper case or digit after;
          |                  # OR
          (?<=[0-9])         # digit before,
          (?=[[:upper:]])    # upper case after?
          /\ /xg;            # Replace with a space.
