tried so far

Tried with simple proc to ensure that problem in concrete case not inly in limit itself but also in expansion. So, simple substitution to :

p:=proc(expr,n) local s, exprout;
exprout:=expr;
for s in indets(expr) do
if y in indets(s, symbol) then
exprout:=subs(s=convert(series(s,y,n),polynom), eval(exprout,1));
end if;
end do;
return exprout;
end proc:

with expr=Hexpr and n=5 without success. Could it be somehow better done?

doubts

Had a look. This expression has length ~ 100 pages and depends on 3 parameters
without any assumptions (may be complex constants).

Why do you expect a limit exits and a CAS can find it in reasonable time?

For your underlying question: with(MultiSeries) sometimes is a way.

But if the expression is very lengthy or complicated it may be, that
the system hangs up in intermediate automatic simplifications.

Just try 'simplify' or 'normalize' on your example.
