That depends on the temperature of your basement and your local climate. Dehumidifiers do not function well at lower temperatures, so under 65 degrees it is almost a waste of money to run them. Plus, as the air temperature drops, the risk of freezing the coils increases (read the next question for more on freeze-ups). If you heat your basement, the warm air will move moisture from the basement to the house above, keeping the humidity lower in the basement and slightly humidifying the rest of the house.
In areas where the ground is frozen for most or all of the winter, the amount of moisture that will migrate through the basement floor and walls will drop dramatically in the winter, so the need for dehumidification decreases. However, if you live in a temperate area, and your basement is not heated, you may have to run the dehumidifier year round. If you are in search of a humidifier/ dehumidifier your best bet is to contact the experts at Extreme Supplies of MI for all your equipment needs.
