Do you often wake up with a scratchy throat or stuffy nose? Poor indoor air quality could be to blame. Excess moisture allows allergens like dust mites and mold to thrive. This can trigger respiratory issues, allergies, and even headaches. Maintaining proper humidity levels is the key to a healthy home environment.
An in duct dehumidifier, sometimes referred to as a whole house dehumidifier, offers an effective solution for controlling moisture levels. It removes excess humidity from the air circulating through your HVAC system's ductwork. This improves air quality throughout your entire home. Let's explore what a whole house dehumidifier is and how it can benefit you.
What is a in duct dehumidifier?
An in duct, or ductable dehumidifier is designed to integrate seamlessly into your home's existing HVAC system. As air circulates through the ductwork, the dehumidifier pulls it in from the return duct. The air then passes over a cold coil or cooling element that condenses excess moisture vapor from the air stream. The now dehumidified air gets redistributed back through the supply ductwork.
Unlike portable dehumidifiers that only treat the air in a single room, in-duct units provide whole-house humidity control. Their direct integration with your HVAC system's air distribution network allows coverage in every room and living space.
Key Benefits of a Dehumidifier
Improved Indoor Air Quality
Reducing excess moisture minimizes allergens like mold spores and dust mites that thrive in humid environments, providing significant relief for allergy and asthma sufferers.
Energy Savings
With proper humidity control, you can raise your air conditioning thermostat temperature a few degrees while still maintaining a comfortable indoor environment. The U.S. Department of Energy states that for every one degree you raise your thermostat, you can save approximately 3% on cooling costs during the summer months when using a dehumidifier.
Preventing Moisture Damage
The Environmental Protection Agency (EPA) estimates that humidity and moisture-related issues cost American homeowners billions of dollars each year for repairs like mold remediation, wood rot, drywall damage, and more. An in-duct dehumidifier helps prevent costly moisture damage to your home over time.
Additional Benefits
Other key benefits include quiet operation since the unit is located out-of-sight, low maintenance requirements compared to portable models, and whole-home coverage from a single integrated system.
Many modern in-duct units also incorporate air filtration capabilities, capturing airborne particulates like dust, dander, and other pollutants in addition to controlling humidity levels.
Choosing the Right Model
The AlorAir Sentinel HDi90 is an excellent choice for larger homes or commercial spaces requiring superior dehumidification performance. This powerful commercial-grade dehumidifier is designed to integrate seamlessly with HVAC systems up to 8 tons in capacity.
With an impressive moisture removal rate of 90 pints per day, the HDi90 can handle even the most humid environments easily. Its durable construction and corrosion-resistant aluminum coils ensure long-lasting, reliable operation.
Energy efficiency is a priority as well - the HDi90 meets ENERGY STAR qualifications for dehumidifiers. Its built-in digital humidistat allows precise humidity control, while the low-temperature operation down to 33°F makes it suitable for basements or other cool spaces.
Convenient features like the auto-restart after power outages and the option for external drainage or condensate pump installation add to the HDi90's versatility. It also comes with a 5-year warranty.
Whether you need to protect a large home, office, warehouse, or other commercial facility from excess moisture, the AlorAir Sentinel HDi90 (Duct) provides the heavy-duty dehumidification you can rely on. Its robust capabilities and seamless HVAC integration make it an ideal solution for whole-building humidity control. With strong product warranties and excellent customer service, AlorAir Crawlspace is a trusted choice.
Professional Installation is Required
While portable dehumidifiers are relatively simple plug-and-play appliances, in-duct models require professional installation by an experienced HVAC contractor. The process involves carefully integrating the dehumidifier unit into your existing ductwork system and setting up proper drainage.
There are two common installation methods used:
- Dedicated return-to-supply plenum - In this approach, a new return duct is installed that pulls air directly into the dehumidifier inlet before the dehumidified air is discharged into the HVAC system's main supply plenum.
- Tying into existing ducts - With this method, the dehumidifier pulls air from the main return duct and discharges the dehumidified air into the supply duct downstream of the air conditioning coil.
The dehumidifier unit itself is typically installed out-of-sight in an attic, basement, or mechanical room near the HVAC air handler. Proper drainage setup, either tying into the home's plumbing or using a condensate pump, ensures automatic water removal without the need for manual emptying.
FAQs
How is a duct dehumidifier different from a portable unit?
In-duct dehumidifiers are integrated into your home's HVAC system and ductwork to provide whole-home dehumidification. Portable units are limited to single rooms and require frequent drainage and maintenance.
Can I install one myself?
While handy homeowners can attempt installation, it is highly recommended to hire a professional HVAC technician. Improper installation could lead to leaks, and inefficiency, and may even void the manufacturer's warranty. Proper sizing and integration into your ductwork are crucial.
How much does a duct dehumidifier cost?
The upfront cost is higher than portable units, typically ranging from $1,000-$3,000 for the equipment and professional installation. However, the energy savings, low maintenance, and improved home comfort provide an excellent long-term return on investment.
How long do dehumidifiers typically last?
With proper installation and maintenance, a quality in-duct dehumidifier can last 10-15 years. Be sure to follow the manufacturer's recommendations for filter changes and service to maximize the lifespan.
Breathe Easier with Whole-Home Humidity Control
The ideal relative humidity range for homes is between 30-50% to minimize health risks from allergens while also preventing moisture issues like mold, mildew, and wood rot. A ductable dehumidifier provides automated whole-home humidity control to maintain these optimal levels.
No more waking up with allergy symptoms, dealing with musty odors, or worrying about moisture damage to your home's structure and belongings.
