Is it worth replacing?
Efficient as certified dehumidifiers go, $48/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $48/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
