Is it worth replacing?
The KESNOS CTH30B is already efficient for its category at $22/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.
Compare current ENERGY STAR certified dehumidifiers before buying.
Protecting what you have
At $22/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
