Yes, a whole-home dehumidifier is worth it for many homeowners who struggle with excess indoor humidity. If your home feels sticky, smells musty, or remains humid even while the AC is running, a whole-home dehumidifier can improve comfort, indoor air quality, and moisture control throughout the house.
While air conditioners remove some humidity, they aren’t designed to control moisture year-round. A whole-home dehumidifier can control humidity and moisture.
Quick Takeaways
- Whole-home dehumidifiers remove excess moisture throughout the home.
- They improve comfort, indoor air quality, and humidity control.
- They work alongside your air conditioner, not replace it.
- They’re especially beneficial in humid climates like Florida.
- Homes with persistent humidity often benefit the most.
What Does a Whole-Home Dehumidifier Do?
A whole-home dehumidifier continuously treats air inside your duct system. It pulls damp, moist air from inside your home into the unit. The warm air passes over your AC’s cool evaporator coils, where the water vapor condenses into liquid water.
Next, the unit collects the water drops and drains them through the condensate drain. Finally, the dry air is reheated to the desired room temperature and recirculates through your vents.
The difference between your AC and a whole-home dehumidifier is that the AC manages temperature, while the dehumidifier manages only moisture and humidity. The AC can remove some moisture during the cooling cycle, but it shuts down once it reaches the desired temperature.
The whole-home dehumidifier extracts moisture when absorbing heat, but it doesn’t cool the air. The AC pushes heat outside, and then it cools the indoor air. The whole-home dehumidifier uses humidistats that actively remove moisture even after the AC shuts down.
The ideal indoor humidity level is between 30% and 50%. This humidity level can prevent the growth of bacteria and mold spores. It can also improve allergy symptoms and reduce respiratory illnesses.
Signs a Whole-Home Dehumidifier Is Worth It
There are several reasons that a whole-home dehumidifier is worth it. You may notice that your home feels sticky or muggy, or the AC runs but the humidity levels remain high. You may notice musty odors, that mold or mildew keep returning, or that condensation forms on your windows.
A whole-home dehumidifier can manage these problems. You will notice improvement in your allergy symptoms after an installation, and your indoor humidity levels will stay below 50%. For these reasons alone, a whole-home dehumidifier is worth it.
Whole-Home vs. Portable Dehumidifier
A whole-home dehumidifier is installed near your HVAC system. It works with the HVAC system to remove moisture from the air throughout your home. A portable dehumidifier is a standalone product. It can be moved around to address moisture and humidity in individual living spaces.
The coverage and capacity of a whole-home unit range from 70 to 130 pints of moisture each day. These units manage spaces ranging in size from 2,200 to 7,200 square feet. A portable dehumidifier removes only 20 to 50 pints per day. They are designed for spaces ranging from 200 to 1,500 square feet.
A whole-home dehumidifier is more convenient. You can just set the whole-home dehumidifier and forget about it. The portable unit requires you to empty the internal water bucket frequently. Once the bucket is full, the unit shuts down.
It will not start up again until you empty the bucket. If you want continuous drainage, you’d need an internal pump or a gravity drain.
Maintenance requirements for a whole-home unit are minimal. You’d need to clean it and replace the filter annually. Our HVAC technicians can do this during annual HVAC maintenance.
A portable unit, however, requires more frequent maintenance. You’ll need to regularly empty the water reservoir, clean the internal bucket, and replace the filter frequently. If not, you could see some mildew or mold growth in the unit.
Is It Worth It For Florida Homes?
Since Florida has year-round humidity, a whole-home dehumidifier is worth it. Your AC is designed to manage temperatures and keep your home comfortable. It isn’t designed to continuously manage humidity and moisture. However, a whole-home dehumidifier can. It will remove excess humidity and moisture, enhancing your comfort.
You can run your AC at a higher temperature and save on energy costs. The air becomes drier in your home, requiring less energy and reducing overall consumption. This also means less strain on your AC. Since the unit manages dampness, it can starve mold spores and prevent them from reproducing.
