5 Things to Know When Shopping for a Crawl Space Dehumidifier

Maintaining a sturdy foundation and a comfortable living space requires effective humidity control, especially in crawl spaces. Excessive moisture in these areas can lead to mold, mildew, and structural concerns. Crawl space dehumidifiers are crucial tools that eliminate excess moisture and ensure a consistently dry environment. 

We understand that selecting the right crawl space dehumidifier requires careful consideration. So, we’ve compiled a list of five things to know when shopping for the ideal model for your crawl space. Gain the insights you need to make a well-informed decision to protect your home’s health and safety. 

What is a Crawl Space Dehumidifier? 

A crawl space dehumidifier extracts excess moisture from the air in your home’s crawl space. Unlike standard dehumidifiers intended for living spaces, crawl space dehumidifiers are built to: 

• Operate in cooler temperatures: Standard dehumidifiers struggle in the lower temperatures of crawl spaces, leading to reduced performance and high energy bills. Crawl space dehumidifiers are engineered to thrive in these cooler conditions, ensuring consistent moisture removal. 
• Handle higher humidity levels: Crawl space dehumidifiers have powerful extraction capabilities, tackling even the most stubbornly damp environments. 
• Withstand harsher conditions: Crawl space dehumidifiers are built with durable materials and components that withstand dust and dirt for long-lasting performance. 
• Regulate humidity: Many crawl space dehumidifiers contain built-in humidistats that adjust automatically to the current crawl space humidity level. 

Crawl space dehumidifiers create a consistently dry and healthy environment beneath your home, protecting your foundation, enhancing air quality, and preventing harmful mold and mildew. Remember, a healthy crawl space contributes to a healthy home – and a crawl space dehumidifier is vital in achieving that balance. 

Five Factors to Consider When Shopping for a Crawl Space Dehumidifier 

Selecting the right crawl space dehumidifier requires careful consideration of several key factors. 

1. Understand Your Crawl Space Needs 

The size and type of dehumidifier you need depend on the specifics of your crawl space. Factors to consider include: 

• Square footage: Measure your crawl space area to determine the dehumidifier’s capacity needed. 
• Average humidity level: Invest in a hygrometer to measure your crawl space’s humidity levels. Aim for a range of 30-50% for optimal comfort and mold prevention. 
• Crawl space classification: Is your crawl space encapsulated, vented, or unvented? Each type has different moisture management needs. 

Assessing these factors ensures that you choose a dehumidifier capable of managing the moisture levels in your home’s crawl space. 

2. Crawl Space Dehumidifier: Performance and Longevity 

The durability and performance of a crawl space dehumidifier are essential. Look for these features to ensure optimal performance: 

• Durable construction: Choose a unit made from corrosion-resistant materials like galvanized steel or plastic. 
• Efficient operation: Energy-star certified models save you money on your electricity bills in the long run. 
• Drainage: Depending on the humidity level and size, a crawl space drain pump might be necessary for continuous moisture removal. 

Identifying whether a drain pump is necessary for efficient moisture removal and optimal dehumidifier operation is crucial. Contact a professional to determine if a drain pump is required for your crawl space. 

3. Crawl Space Dehumidifier: Features and Accessories  

Modern crawl space dehumidifiers are equipped with many features that improve functionality and convenience, such as: 

• Air filters: These improve the air quality by capturing dust, allergens, and other airborne particles. 
• Automatic drainage: Eliminates the need for manual emptying of the water tank. Choose a tank capacity that matches your crawl space’s size and humidity levels to avoid constant emptying. 
• Humidistat control: Ensures the dehumidifier only operates when necessary, saving energy. 

4. Crawl Space Dehumidifier: Cost and Value  

Cost is important, but it is also crucial to consider the long-term value of a crawl space dehumidifier when deciding. Opting for a high-quality, energy-efficient model can lead to savings on both energy bills and repairs over time. Consider these factors: 

• Upfront cost: Compare prices, brands, and models to find one that fits your budget. 
• Energy efficiency: Choose ENERGY STAR certified models for enhanced energy cost savings. 
• Warranty: A comprehensive warranty protects your investment against unexpected malfunctions. 

A comprehensive warranty also protects your investment against unexpected failures. Contact a professional to learn about warranty options for your chosen crawl space dehumidifier.

5. Crawl Space Dehumidifier: Operational Factors   

Noise levels can disrupt your comfort, so choose a dehumidifier that operates quietly. Look for models with decibel ratings below 40 dB for near-silent operation.
