Dehumidifier Operating Temperature Q&A

Question
Subject: Operating temperature for dehumidifiers

You stated that one of your dehumidifiers has an operating temperature range down to 45°F. What happens if the temp goes down to say 35°F?

Thanks,
Carolyn

Answer
Hi Carolyn,
You are probably talking about the Comfort-aire 50- or 65-pint low temperature dehumidifiers. The dehumidifier will continue to run but it will not remove any moisture. In addition, if the coils begin to freeze up these units will shut the compressor off but the fan will continue to run. Keep in mind that while the compressor is off to allow the evaporator coils to warm up, there is no dehumidifying occurring. Therefore, you will basically be running a fan in the room.

Some of the less efficient dehumidifiers will allow the evaporator coils to ice up where the unit will continue to run to attempt to remove the moisture from the air. However, what will actually be happening is there will be no dehumidification occurring while the unit will continue to ice up and eventually burn out because the airflow will be cut off.
