How does a dehumidifier work?

Dehumidifiers remove excess moisture from the air through an internal coil and fan system. Warmer air contracts as it passes through refrigerated coiling and is retained within the machine as condensation.

Do air conditioners dehumidify?

Yes, they do as air passes over refrigerated coils, which pull moisture out before the air flows from the unit. However, using a dehumidifier in conjunction with air conditioning units is still recommended, alternating the use of each type of equipment to reduce energy use and costs.

Should a dehumidifier run all the time?

It is recommended to run a dehumidifier no more than 12 hours per day. Any time beyond the 12-hour mark can lead to costly energy bills and necessitate more frequent maintenance on the equipment.
