The Importance of Installing a Dehumidifier in Your House


Do you often battle excess moisture and high humidity in your home? Does condensation on windows and musty smells bother you? If so, it might be time to consider installing a dehumidifier in your house. This article will discuss the importance of having a dehumidifier, its benefits, and how it can improve indoor air quality and overall comfort.

Why is a Dehumidifier Important?

Excess humidity in your home can lead to many problems for you and your property. Here are some reasons why installing a dehumidifier is essential:

  1. Prevents Mold and Mildew Growth: High humidity levels create a breeding ground for mold and mildew. These fungi can thrive on walls, furniture, and even in the air. Not only are they unsightly, but they can also cause serious respiratory issues and other health problems.

  2. Protects Your Property: Moisture can damage the structural integrity of your home. It can warp wooden furniture, cause paint to peel, and even weaken the foundation. By reducing and balancing humidity, you can safeguard your investment and prevent costly repairs.

  3. Improves Indoor Air Quality: Excessive moisture often creates stale and unpleasant indoor air. A dehumidifier helps remove excess moisture, producing fresh, clean air free from allergens and odors.

  4. Enhances Comfort: High humidity makes you feel sticky and uncomfortable. Maintaining a more balanced humidity level can create a more pleasant living environment for you and your family.


Retrofitting a Ventilating Dehumidifier

To illustrate the importance of installing a dehumidifier, let’s look at a video created by Matt Risinger, a renowned home improvement and construction expert. In the video, Matt showcases how retrofitting a ventilating dehumidifier can solve humidity issues in an older house without proper moisture control.

Matt’s video highlights the following key points:

  1. The Mechanical Room: The house featured in the video has an upstairs attic that serves as a mechanical room. This is where the heating and cooling systems, ductwork, and furnaces are located.

  2. Original Ductwork and Furnaces: The house was built in 2010, and its original ductwork and furnaces were still in good shape. However, the ventilation controller was no longer functioning correctly, which led to humidity problems.

  3. Fresh Air Input: Matt connected a dehumidifier from Aprilaire to the house’s fresh air input to address the high humidity. This ensures that dehumidified air is brought in, improving the overall air quality.

  4. Dumping Dehumidified Air: The dehumidified air is cleverly dumped into the supply side of the furnaces, effectively distributing the dry air throughout the house.

  5. Aprilaire Controller: The Aprilaire controller plays a crucial role in this setup. It controls when and how much fresh air is brought into the house, ensuring optimal humidity levels are maintained.


Installing a dehumidifier in your house can be a wise investment that can significantly improve indoor air quality, protect your property, and enhance overall comfort. Matt Risinger’s video demonstrates how retrofitting a ventilating dehumidifier can effectively solve humidity issues in an older home. By considering products like Aprilaire’s dehumidifiers, you can enjoy the benefits of a drier and healthier living environment.

The installation typically involves finding the optimal location for the dehumidifier, ensuring proper ventilation and drainage, and setting up the controls for optimal performance. Once installed, you can expect to see a reduction in musty odors, mold and mildew growth, and condensation on windows and walls.

In addition to improving air quality and protecting your home from moisture damage, a dehumidifier can also help lower energy costs by reducing the workload on your air conditioning system. This can result in a more comfortable and affordable living environment.

Overall, investing in a dehumidifier is a practical and worthwhile decision for any homeowner looking to improve their indoor environment. With professional installation and the right product, you can enjoy the benefits of a drier, healthier, and more comfortable home.
