Is a Whole House Dehumidifier Worth It?

Are whole house dehumidifiers worth it?

As a homeowner, you want to make the right choices about installations, additions, or other adjustments to make to your home as comfortable as possible. But when it comes to adverse weather conditions, such as strong humidity, you could be left sweaty and uncomfortable in your household. 

When these problems arise, you may want to consider installing a whole house dehumidifier.

What Does a Whole House Dehumidifier Do?

A dehumidifier’s job is to help control humidity levels inside of your household, hopefully decreasing it. Essentially, it takes the excess moisture out of the air in your home by collecting it and dumping it into a reservoir (in the case of smaller units) or piping it through a drainage system (whole house units). There are many different types of dehumidifiers, from ducted to portable, but all have the end goal of having your home obtain a humidity level below 50%. 

Many people choose to install whole house dehumidifiers for varying reasons, from allergies to general comfort. If you are thinking about purchasing one, we’ll discuss the pros and cons of them while giving you our top picks below.

Whole House Dehumidifier Pros and Cons

Whole house dehumidifiers work really well to reduce the percentage of humidity in the air in your home.

As with the installation of any major appliance, you want to be sure you are aware of not only the advantages, but any drawbacks or obstacles that come with it. It’s often recommended that the average indoor humidity level for a home be somewhere between 40%-60%, but various factors could cause that percentage to go up or down.


There are many reasons why you might like to have a dehumidifier for your whole home, and most of them relate to the environment inside your living space.

  1. More Efficient Cooling – In a way, your dehumidifier works similarly to an air conditioner, as it processes the air in your home, and in so doing filters out dust, allergens, and the like. Essentially, adding a dehumidifier will keep your home cool because it’ll suck out the humidity and create air that is easier to breathe.
  2. Better Air, Better Environment – Too much moisture in the air can cause serious issues for your home, such as mold. Dehumidifiers help reduce the incidence of this problem by removing moisture particles that can cause mold to grow. Other issues with your home can include problems with wood flooring or furniture, and possible odor from humidity. Thus, installing a whole house dehumidifier can help make the air a little more enjoyable, by improving your overall indoor air quality.

These are just a few of ways that your dehumidifier can help make your home’s air more enjoyable.


Of course, whole house dehumidifiers do have a minor drawback when it comes to upfront installation.

  1. Cost – One of the biggest deterrence for many people when considering buying a whole house dehumidifier is the upfront cost. Installation can run you from hundreds up to a few thousand dollars depending upon the size of your home and your particular needs. You must also consider the cost of running the dehumidifier, which can add to your energy bill. Dehumidifier costs range from $1,200 to $2,800 for bigger houses, and $1,000 to $2,000 for smaller or average-sized homes. Even with such costs, you need to ensure you choose the right dehumidifier that can remove at least 70 pints/day of moisture. Thus, not only is it a costly investment, you need to consider which dehumidifier unit is right for you.

    We live in Central New Jersey. Humidity can be an issue , even when the outside temperature is moderate 65 – 75 degrees. This can happen from April through September – not every day, but often enough to make us crank up the AC even when cooling is not really needed. In fact, in those cases, our home gets too cold. We’re trying to decide what to do and if installation of a whole house dehumidifier makes sense. By that I mean DOES IT WORK? and will it cause us to use our air conditioner less? Also, what is the ballpark cost in this area? We have a 2500+finished basement colonial style home.

  7. NC Family says:

    We began using a dehumidifier in our 2900 sg.ft. home four years ago here in NC, and are sold on the benefits. As we began researching, the first thing we did was to buy a humidistat to see what humidity was in our home. After several days of moving the sensor throughout the house, we ended up with indoor humidity ranging from 57-63 percent. So we initially bought a cheaper portable model from a close-out store for $89, which was able to drop the house down to 50% humidity, which was very noticeable. We decided to purchase a larger portable model from Lowe’s for $279. We maintain a 45% humidity in the house now and run our AC at 77 during the day, and 75 at night as we like colder sleeping temps. The first Lowe’s unit failed within the first year, so the mfg sent us a replacement, which did not function correctly, requiring a third unit to be sent. That third unit has operated for three years with no issues.

    1. Thank you for sharing such detail information in your post. Only as an adult did I begin my suffering with year-round allergies. I too live in NC however, I I have discovered when I travel outside of my home state, I actually feel better (less scratchy throat, clear eyes, etc.). Thereby I’m starting to research better in home air quality. I know there has to be something to it but I admit I am conflicted on what amount of humidity is best for ultimate lung health considering healthcare professionals tell us to use a humidifier (put humidity in the air) when we have a cold, etc. Would you mind sharing the exact benefits you have personally experienced from having a dehumidifier and do you use the dehumidifier year around to maintain 45% humidity or do you adjust the humidity depending on the season(s)? TIA

  8. Can a house that has zone heating, uses heat pump rather than forced air heating, be set up with whole house dehumidifier? Also, the house does not have central air.

      If you do not have existing ductwork, it would be difficult to install a whole house dehumidifier. You would have to run ducts to be able to push and pull air from different areas.
