We live in an old farmhouse with a basement that has a stonewall foundation and a dirt floor. What they used to call a root cellar. Due to rain and the humidity of summer the freezer in the basement is always sweating and things are damp. With the new Frigidaire Dehumidifier things have changed. The basement is no longer damp, there is no condensation on the freezer and the basement is dryer. There has been a slight increase in our electric bill but the Frigidire is running constantly. However our electric bill is still reasonable. very pleased with this Frigidaire Dehumidifier.
