Yes, Neutering MAY help, however it doesn't guarantee that your sibe will calm down.
My first thought reading your post is . . .
What do you feed him ??
A lot of hyperactivity is linked to food.
Jumping up at visitors is something that should have been addressed as a puppy and taught
that it is NOT ok to do this.
One method is that YOU greet the visitor away from the husky.
Give the visitor a treat.
The visitor must make the Husky SIT before he gets the treat.
This way the Husky will learn that when a visitor comes in,
IF he sits then he will get a treat.
Thus stopping the jumping.
However it is very common for Huskies to give visitors to the home a far more enthusiastic welcome that to it's owners.
