Choosing Your Whole House Dehumidifier: A Simple Buying Guide
A whole house dehumidifier works hard to keep your entire home dry and comfortable. Too much moisture causes musty smells, mold growth, and can damage your home. This guide helps you pick the right one.
Key Features to Look For
When shopping, check these important features first. These make a big difference in how well the machine works.
1. Sizing and Capacity (Pint Rating)
How much water can it remove?
- Pint Rating: This tells you how many pints of water the unit removes in 24 hours. Look at your home’s size and current humidity level. A damp basement needs a higher pint rating than a dry main floor.
- Rule of Thumb: Bigger homes or very wet areas need units rated for 70 pints or more.
2. Installation Type
Where does the water go?
- Ducted (HVAC Integrated): These connect directly to your existing heating and cooling (HVAC) system. They treat the air as it moves through the ducts. This is the best option for whole-house coverage.
- Non-Ducted (Stand-Alone): These sit in a room, often a basement, and use a hose to drain water. They treat the air around them well but might not cover the whole house evenly.
3. Drainage Options
How is the water removed?
- Gravity Drain: The unit uses gravity to send water down a hose to a floor drain or sump pump. This is easy if a drain is nearby.
- Condensate Pump: If you don’t have a floor drain nearby, a pump pushes the water up or across to a distant drain or sink. This offers more placement flexibility.
4. Energy Efficiency
Dehumidifiers use electricity. Look for the Energy Star certification. Energy Star models use less power to remove the same amount of water. This saves you money on your utility bills.
Important Materials and Build Quality
The materials used affect how long your dehumidifier lasts.
Durable Construction
- Cabinet Material: Look for sturdy metal casings rather than thin plastic. Metal resists vibration and wear better over time.
- Coil Material: The evaporator coils are important for cooling and condensing moisture. Coils coated with epoxy or special coatings resist corrosion, especially if you live near the ocean or use the unit in a slightly humid basement.
Factors That Improve or Reduce Quality
Good quality machines have features that make them reliable and easy to use.
Quality Boosters:
- Automatic Humidistat: This lets you set your desired humidity level (usually 45-55%). The machine turns on and off automatically to maintain that level.
- Defrost Cycle: If you run the unit when the air is cool (like in a cool basement), ice can form on the coils. A good defrost cycle melts this ice safely without wasting energy or stopping the drying process for too long.
Quality Reducers:
- Loud Operation: Some cheaper models use louder fans. Since these run often, noise level matters, especially if the unit is near living areas. Check decibel (dB) ratings.
- Poor Controls: Hard-to-read or confusing digital displays reduce the user experience.
User Experience and Use Cases
Think about who will use the machine and where it will live.
Ease of Use
If you are installing a ducted model, professional installation is usually required. For stand-alone units, make sure the water collection bucket (if you don’t use continuous drain) is easy to reach and empty. Good models offer simple digital controls that anyone can understand.
Ideal Use Cases
- Basement/Crawlspace: These areas often trap moisture. A dedicated unit here prevents damp smells from spreading upstairs.
- Whole House Protection: Integrated HVAC models are perfect for homes in humid climates (like the South) where humidity affects every room equally.
Whole House Dehumidifier FAQs
Q: What is the ideal humidity level for a home?
A: Most experts recommend keeping indoor humidity between 40% and 55%. This range feels comfortable and stops mold and mildew from growing.
Q: How is a whole house dehumidifier different from a portable one?
A: A whole house unit is usually installed permanently into your HVAC system to treat air moving through your ducts. A portable unit sits in one room and only treats the air immediately around it.
Q: Will this machine help with allergies?
A: Yes. By lowering moisture, you reduce the environment where dust mites and mold thrive. This often leads to better air quality for allergy sufferers.
Q: How often do I need to clean or maintain the unit?
A: You should clean or change the air filter monthly, depending on how dusty your home is. The coils might need professional cleaning every few years.
Q: Can I install a whole house dehumidifier myself?
A: Ducted systems require knowledge of HVAC wiring and ductwork, so professional installation is usually best. Stand-alone units are often DIY friendly.
Q: Does it run all the time?
A: No. If you set the humidistat correctly, the unit only runs when the air gets too humid, saving energy.
Q: What happens if the power goes out?
A: Most good units will automatically restart and return to their previous settings once the power comes back on.
Q: Do I need a permit to install one?
A: This depends on your local building codes. Always check with your city or county office before installing major appliances connected to your HVAC system.
Q: Will the dehumidifier make my house feel colder?
A: Yes, slightly. Dehumidifying involves cooling the air to pull out the moisture, similar to how an air conditioner works. This effect is usually minor, especially when integrated with your existing system.
Q: What is the typical lifespan of a quality unit?
A: A well-maintained whole house dehumidifier usually lasts between 10 and 15 years.
