How to Choose the Right Whole-House Ducted Dehumidifier?

Selecting the right whole-house dehumidifier requires matching capacity to your home size, understanding installation requirements, and evaluating features that matter for your situation. Here’s what to consider before making your investment.

Capacity and Square Footage

Capacity is measured in pints per day (PPD), indicating how much moisture the unit removes in 24 hours. Match capacity to your home’s square footage and climate conditions. Homes in humid climates like Florida or the Gulf Coast need more capacity than homes in drier regions.

For homes under 2,000 square feet, 70 PPD units like the AprilAire E070 provide adequate capacity. Homes between 2,000 and 4,000 square feet typically need 80-100 PPD. Larger homes above 4,000 square feet should consider 100-130 PPD units.

Look at AHAM ratings rather than saturation ratings when comparing. AHAM testing at 80 degrees F and 60% relative humidity gives realistic performance expectations. Saturation ratings at extreme conditions paint an optimistic picture you won’t experience in normal operation.

HVAC Integration Options

Whole-house dehumidifiers connect to your HVAC system in two primary ways. Return-side installation pulls air from your return duct, dehumidifies it, and returns it to the supply side. This method treats all air circulating through your HVAC system.

Dedicated ducting creates a separate circuit independent of your HVAC. The dehumidifier pulls air from one location, removes moisture, and supplies dry air to another location. This approach works well for targeting specific problem areas like basements.

Some systems, like the ALORAIR WHD100, offer fresh air intake capability. This feature brings filtered outdoor air into your home while exhausting stale air, addressing indoor air quality beyond humidity. For more on HVAC alternatives, see our guide to ductless mini-split systems.

Energy Efficiency Ratings

ENERGY STAR certification indicates efficient operation that won’t dramatically increase your electric bill. Look for ENERGY STAR Most Efficient certification for the best performance per watt consumed.

Wattage ratings help estimate operating costs. A 600-watt unit running 8 hours daily consumes about 4.8 kWh per day. At average electricity rates, that’s roughly $15-20 per month in additional energy costs during peak humidity seasons.

Efficient units often include automatic defrost systems that prevent ice buildup on coils. In cooler temperatures like crawl spaces and basements, this feature prevents the unit from wasting energy trying to dehumidify frozen coils.

Installation Considerations

Professional installation typically costs $1,000 to $3,000 depending on complexity. Attic installations often cost more due to access challenges and additional ductwork. Basement installations may be simpler if drain access exists.

DIY installation is possible for handy homeowners, especially with complete bundle kits. Consider your comfort level with electrical connections, ductwork, and plumbing. AprilAire bundles include detailed instructions and necessary hardware.

Weight matters for installation location. Units over 80 pounds may require two people for positioning and mounting. Consider structural support if installing in attics or suspended locations.

Drainage Options

Continuous drainage is essential for whole-house units. Gravity drains work when a floor drain or sump pump sits below the dehumidifier’s drain outlet. The unit must be elevated to create necessary slope.

Condensate pumps lift water vertically when gravity drainage isn’t possible. Some units like the AprilAire E080W include pumps; others require separate purchase. Pumps add cost but enable installation flexibility.

Regular maintenance includes checking drain lines for clogs. Algae and mineral deposits can block drainage over time. Annual inspection prevents water damage from backed-up condensation. For keeping your entire system clean, check our recommendations for air duct cleaning kits.
