Any experience on freezing

Hey y'all! My wife and I are trying to conceive a baby. My best friend is helping us out however he is fixing to go on a long vacation and will miss our next few ovulation periods. We don't want to use a sperm bank to freeze. I was wondering if anyone had any experience freezing at home? Or if they would still be viable kept in a refrigerator or a deep freezer for a week or so?
