When renting a dehumidifier, be aware of potential hidden fees such as delivery and pick-up charges, which may be flat or mileage-based. Fuel or recharge surcharges, damage waivers versus full insurance, cleaning fees for concrete or mud, late-return penalties, and overtime hours can also add to the overall cost.
