Do Dehumidifiers Work in Winter?

Do Dehumidifiers Work in WinterDo dehumidifiers work in winter? Many people like the idea of asking a question and then getting a straight answer that works for everyone across the board. However, that is not the case when it comes to answering this particular question. Sometimes, a dehumidifier can be an absolute necessity in winter and other times, it is completely pointless to use it. It all depends on several factors that will influence the use of the device and in many cases, those factors will be specific to your home and the room that you plan on using it in.

Winter Conditions in Your Region

If you use a dehumidifier during the winter inside your basement in order to prevent the growth of mold, your need for the machine will depend on the type of temperatures that are typically experienced in the region you live in, along with a few other factors. If you live in a climate that is extremely cold, there is really no reason to use a dehumidifier during the winter because it will quickly become impossible to use it in all likelihood. This is because of the way these machines work. The entire point of their existence is to pull moisture out of the air and in order to do that, they hold the moisture inside their coils and then release it into an enclosed system. If you are trying to use one in temperatures that are well below freezing, the coils will ultimately freeze up and the machine will stop working. Therefore, they are rather pointless if you are using them in a severely cold climate.

However, if you have a home that is located in an area that is typically rather warm, even during the winter, you might find it necessary to use a dehumidifier. With that being said, you still don’t need to use one unless you have a lot of moisture content in a particular room or you live in an area that experiences a lot of high relative humidity on a near-constant basis. In these cases, you should probably be using a dehumidifier almost year-round. If you happen to live in a climate that is much dryer, you can probably get away with only using the dehumidifier during warmer months.


Your best course of action is to pay attention to whether or not the dehumidifier is freezing up when you try to use it. Along with that, take note of the condition of the particular area that you are using it in. Is there a lot of excess moisture in the room? Do things feel damp or do you notice mold growing anywhere? If the answer to these questions is yes, you absolutely need to be using a dehumidifier regardless of the time of year. However, if the answer to these questions is no and you notice that the dehumidifier you are using is freezing up, you are really not doing anything except using electricity you don’t need to use and possibly damaging the dehumidifier by trying to run it. In that case, set it aside so that you can use it during warmer months and keep an eye on the overall condition of the room so that you can take action if anything changes.
