Lifespan
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 Waykar CHWA80A is already efficient for its category at $49/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
A dehumidifier like the Waykar CHWA80A is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
