10 Best Ducted Whole House Dehumidifier

The summer is right at the corner. Soon, shoppers will be scrambling to find the best air conditioning and dehumidifier appliances.

If you’re thinking about dehumidifying the entire house, you should strongly consider a whole-house dehumidifier rather than purchasing several smaller units for each room.

Specifically, see if you can get a whole-house dehumidifier that connects to the home’s existing ductwork. These appliances can be expensive – some cost as much as $2,000.

However, they are incredibly effective. You don’t have to worry about positioning the dehumidifier, and they typically feature continuous drain solutions, so you never have to empty the water bucket. They are also a very cost-effective solution in the end.

Why Choose a Ducted Whole House Dehumidifier

Let’s begin by recapping the benefits of a whole-house dehumidifier. Why but a whole-house unit rather than a separate dehumidifier for each room?


Even if you assume that the cheapest average dehumidifier is priced at $200, how many would you need to serve the entire home? It could be 7+, right? Many good whole-house dehumidifiers cost between $900 and $1,400. So, you could save a few hundred if you shop wisely.


Setting up, checking, and maintaining a different humidifier in every room throughout the home is a tiresome and, frankly, thankless task. Why does it when you can have one dehumidifier serving the entire house that you control from a single control panel?

Hide it away from View

Instead of worrying about where to place the bedroom dehumidifier, where to locate the kitchen dehumidifier, and so on, the whole-home dehumidifier can be tucked away in the basement where no one sees it.

Saves Energy 

A home with several dehumidifiers spread throughout the rooms uses a lot more energy than one with a single, whole-home unit. Why? Because even those smaller dehumidifiers tend to consume between 20-40 watts. Seven of them would consume up to 280 watts. Meanwhile, a standard whole-home dehumidifier consumes about 120 watts.

Signs You Need a Whole House Dehumidifier

Considering their hefty price tags, though, you should only invest in a whole-house dehumidifier if you absolutely need one. The following are three occasions where a whole-house unit makes the most sense;

  • You own the home: Ducted dehumidifiers are most practical if you own the home and would be happy to have a more permanent solution for perennial moisture issues. It’s an install-it-and-forget-it kind of investment similar to whole-home cooling/heating. You only need annual maintenance.
  • A musty odor in the air: A stale smell in the air that’s consistent throughout the home is often a sign of poor air circulation. More importantly, moisture can be a huge contributing factor. A fan can help. But often, you need to address the root cause. That’s when a whole-house dehumidifier comes in handy.
  • Persistent allergies: By now, you likely know that allergies are caused mainly by mold/mildew, both of which thrive in hot, humid conditions. However, the bigger problem is that you can’t solve a mold problem in the home by dehumidifying one room. Mold spores spread very easily. The allergies could easily be caused by mold from the basement. So, whole-home dehumidification is the answer.

What’s a Ducted Whole House Dehumidifier

Ducted, whole-house dehumidifiers are dehumidifier systems that integrate into your home’s HVAC system to extract excess moisture via the existing duct system. They are often contrasted with standalone models that rely on fans to drain moisture from the home.

Advantages of Ducted Whole-House Dehumidifiers

  • Convenience: A major advantage of ducted systems is that you only need to set up the entire system once. After you’re done, you no longer have to worry about positioning the dehumidifier.
  • Energy efficiency: Ducted dehumidifiers rely on the central AC’s fans to draw air from the home. Unlike standalone dehumidifiers, they don’t need built-in fans. The result is reduced energy usage. Most of them are Energy Star certified.
  • Can remove more moisture: If you check around, you’ll find that ducted dehumidifiers have some of the highest moisture removal capacities. Some can remove up to 200+ pints/day. Meanwhile, even the larger standalone units remove under 30 pints/day.
  • Greater durability: It might seem a trivial point, but ducted dehumidifiers generally last longer than their standalone counterparts. Even the build will tell you about the durability differences. Most ducted units are built from metal parts, while nearly all standalone units are made from plastic.

Drawbacks of Ducted Whole-House Dehumidifiers

  • High initial costs: Ducted, whole-house dehumidifiers are by far the most expensive dehumidifiers for domestic use. Some can cost up to $2,000 before accounting for installation costs which often cost up to 25% of the appliance’s price.

How Do Ducted Whole House Dehumidifiers Work?

Although different manufacturers apply different moisture removal technologies, most ducted, whole-house dehumidifiers operate in two ways;

  1. Refrigeration 

This approach involves cooling arm air sucked into the dehumidifier through the grille on one side and passing it over very cold refrigerant lines. Moisture in the air condenses to liquid and drips into a water bucket. The now-dry cool air is then sent back into the home as more warm air is sucked into the dehumidifier.

  1. Absorption/adsorption 

Also known as desiccant dehumidification, adsorption is slightly different. Here, a special humidity-absorbing material known as a desiccant is used. The desiccant is exposed to the air to be conditioned to absorb as much moisture as it can hold. Then moisture-saturated material is moved to a different location of the dehumidifier where it’s recharged to drive off the humidity by heating it.

Whole House Dehumidifier Types

As you go shopping for a ducted whole-house dehumidifier, it’s also important to keep in mind that these appliances can be grouped into three different categories;

  • Compressor/heat pump dehumidifiers: These are mostly refrigerant dehumidifiers that utilize extra-cold refrigerants to remove indoor air moisture. They tend to leave the home a lot cooler than other dehumidifier types.
  • Chemical absorbent/desiccant dehumidifiers: We’ve also discussed desiccant dehumidifiers. They use desiccant material to extract moisture from the air. Then the material is recharged to remove the moisture. Unfortunately, desiccant dehumidifiers aren’t very energy-efficient.
  • Dehumidifier ventilators: Also known as ventilating dehumidifiers, dehumidifier ventilators introduce fresh, filtered air from outside the home while removing stale, warm air from the home. The new air from outside the home is always less humid than indoor air.

Factors to Consider when Purchasing the Best Ducted Whole House Dehumidifier

  • Coverage/capacity: Since ducted dehumidifiers rarely use water collection buckets, you’ll need to focus on the moisture removal capacity. Anything above 50 pints/day is acceptable.
  • Coverage: The manufacturer will usually indicate the recommended coverage for each product in square feet. Make sure your home is slightly smaller than the recommended coverage.
  • Features: Features to prioritize are a humidistat, thermostat, LCD control panel, and remote control. Some advanced units even offer smart/app control. Also, check if it has filters.
  • Continuous drainage: Although most ducted whole-house dehumidifiers use continuous drainage, don’t assume that all of them do. You must check. Also, check whether the drain hose is included or sold separately.
  • Warranty: The best ducted, whole-house dehumidifiers come with at least a 3-year warranty for the compressor and 1-year cover for the other parts.
