Frequently Asked Questions
Why is a high pitched noise coming from my Compressor Dehumidifier?
This noise is present in Compressor Dehumidifiers with R290 refrigerant where the internal fan is not loud enough to cover the noise. The pitch of the compressor changes as the temperature inside the machine rises similar to starting a car in winter is louder and then gradually returns to a normal pitch as the engine warms up. In most cases, the high pitched noise will go away after an hour.
