I am using the TempData in order to preserve my model in when using a RedirectToAction. It works fine, but I have a nagging feeling that it might not be the right thing to do. I really try to avoid using Session data, and I've read that TempData uses the Session. Is it safe to use? Are there issues which might arise in using it in a load balanced environment?

Trivia Question: "Is It Safe?"-- name the movie.

Yes, TempData is backed by session storage, so if you are in a load balanced environment extra care must be taken when using it (sticky sessions, persistent session state, etc).

TempData has been the de-facto choice when using the PRG pattern, and is what it was designed for.

As to whether it's the right thing to do... it depends on your use case!
