At Jerry, Kelly Heating & Air Conditioning it’s absolutely always our number one priority to ensure you’re getting the best services and products possible. Because of this, we strive to bring you the highest quality solutions, services and products (like our Emerald AC systems!) for everything you might need in your home. Considering a whole-home dehumidifier installation for your St. Charles home? If so, you might be interested in what our experts have to say!


As with any major service, purchase, or installation, it helps to fully understand the ins and outs or ups and downs of what you’re getting yourself into. Curious about what makes a whole-home dehumidifier such a great investment here in Missouri? To really understand, you’ll need to know exactly what a dehumidifier does.

Put simply, a dehumidifier draws excess moisture out of the air and permanently removes it. With a small or room system, the moisture collected is dumped into a removable reservoir. For a whole home system, a drainage system is used. The important point is that all of that clammy, nasty moisture is then gone.

How much does it cost to install a whole house dehumidifier?

It costs around $1,500-$3,000 to install a whole house dehumidifier. some things that can affect the price include: 

  • The size of your home.
  • The type of dehumidifier you want installed.
  • The cost to install the dehumidifier.

Getting a whole house dehumidifier installed can help control your home’s humidity level in order to prevent the growth of mold and mildew. To find out more about getting a whole house dehumidifier installed, call us today.

How do I know if I need a whole house dehumidifier?

Some ways you can tell if you need a whole house dehumidifier are:

  • There is condensation on your windows.
  • You notice mold growing inside your home.
  • The amount of humidity in your air is uncomfortable.

Having too much humidity present in your indoor air can lead to issues that affect your home as well as your health. To learn more about getting a whole house dehumidifier installed, contact us today

How long do whole house dehumidifiers last?

Whole house dehumidifiers typically last around 5-10 years. Although, some things that can affect the lifespan of your whole house dehumidifier are: 

  • The type of whole house dehumidifier you have.
  • How often you have your whole house dehumidifier maintained.
  • How often you use your whole house dehumidifier.

To get the longest service life out of your whole house dehumidifier, you should have it maintenanced on a regular basis. To get your whole house dehumidifier serviced or replaced, give us a call today.

Now you, like more than 90 percent of the United States, probably have an air conditioning system. To a minor degree, your AC actually kind of works like a dehumidifier as a secondary function (it’s kind of a byproduct of its actual job).

But, the amount of dehumidification offered by your AC is negligible, especially in climates that are prone to high humidity and moist summer seasons (been outside lately?).

So, since your AC isn’t quite up to the task of keeping your humidity under control, we have to look to other means of keeping optimal moisture levels in the home. Enter dehumidifiers! But what exactly does this do for you? What are the benefits? Well:

  • Whole home dehumidifiers make your home more comfortable. Optimally speaking, for both health and comfort, humans need a humidity level of roughly 30 – 50% relative humidity. When the air of our home is too moisture-rich, that moisture sticks to our skin, and prevents the body’s natural cooling processes, making us hotter and a heck of a lot less comfortable.
  • Dehumidifiers reduce cooling costs. Moisture-heavy air bogs down your AC, making its job much tougher. An air conditioner will do its best to soldier on, but the effort it has to make to do so can make your cooling bills skyrocket. This means you’re paying more for a lot less comfort.
  • When used properly, dehumidifiers protect your home. Excessive moisture can make paint bubble up, furniture warp, and can even generate water damage in walls and floors. A dehumidifier can keep this from happening to you!
  • Dehumidifiers help to deodorize and minimize the risks of mold. Moist air (excessively moist air) promotes rot and fungal growth. This means a humid home is one that is prone to being a bit smellier, and one that can rapidly become a hotbed for mold growth.

With all of these perks, you might be wondering about the downsides, right? Well, there’s really only one big con to consider in all honesty.

  • Upfront investment. A whole home dehumidifier installation is an investment, and like any investment, the benefits should be weighed against the cost. The bottom line is that any home that resides where the air often becomes humid (like here in St. Charles) will absolutely benefit from a dehumidifier system. As long as the cost is within acceptable parameters.

But hey, if the investment is all that’s stopping you from a dehumidifier installation, contact us today about our financing option
