Are whole house dehumidifiers worth it?

As a homeowner, you are often confronted with many choices about installations, additions, or other adjustments to make to your home.

Sometimes problems arise that warrant a fix or replacement, but other times, personal needs or preferences can be the driving force behind making some minor or major changes to your home. But it can be tough to decide if it’s worth dumping the time, money, and energy to complete and maintain.

One such change that you might be considering is installing a whole house dehumidifier.

Essentially, a dehumidifier 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). Many people choose to install whole house dehumidifiers for varying reasons, from allergies to general comfort.

If you are thinking about getting a whole house dehumidifier, read on to learn more about the benefits before taking the plunge or opting out.

Whole House Dehumidifier Pros and Cons

Do whole house dehumidifiers work? Yes, that’s the short answer. Whole house dehumidifiers work really well for what they are meant to accomplish. They will help reduce the percentage of humidity in the air in your home.

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

Pros of whole house dehumidifiers

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.

  • Comfort – One of the most common reasons why many people purchase dehumidifiers is to make their living space more comfortable. If you find that your home is often stuffy, or the air feels heavy, it’s likely that you have a high level of humidity in the air. Installing a whole house dehumidifier can help make the air a little more enjoyable, by improving your overall indoor air quality. If you live in an especially humid climate, such as Florida, Texas, or Louisiana, a whole house dehumidifier can greatly improve the comfort of your home.
  • Home Protection – 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.
  • Allergy Help – All throughout the year, there are many allergens floating in the air that can spell out a nightmare for people with allergies. By regularly filtering your air with a dehumidifier, you can achieve cleaner air quality, which can help alleviate reactions for those breathing it.
  • More Efficient Cooling – In a way, your air conditioner works similarly to a dehumidifier, as it processes the air in your home, and in so doing filters out dust, allergens, and the like. Since dehumidifiers help to clean the air, your air conditioner doesn’t have to work as hard to weed out those particles, and can cool more efficiently.

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

Cons of whole house dehumidifiers

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

  • Cost – One of the biggest deterrences for many people when considering buying a whole house dehumidifier is the upfront cost. Installation of a whole house dehumidifier 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.
