NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
The Keystone KSTAD224F is already efficient for its category at $52/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
The Keystone KSTAD224F already costs $52/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
