How Much Is a Dehumidifier? Explore Whole House Dehumidifier Cost
The cost of a whole house dehumidifier typically ranges from $1,000 to $2,800, including the unit and professional installation. The final price depends on factors like the size of your home, the unit's capacity, drainage requirements, and labor rates in your area. While the upfront investment is higher than portable units, whole-house systems offer whole-home humidity control and can integrate with your existing HVAC system.
Buying or replacing a whole-home dehumidifier is an investment in your home comfort. How much is a dehumidifier? Whole house dehumidifier cost depends on the size of the dehumidifier, the drainage options, and labor for installation.
What Are Whole House Dehumidifier Cost Considerations?
Whole house dehumidifier costs vary based on home size, drainage type, dehumidification capacity, ductwork requirements, and energy efficiency.
Understanding these factors can help you make an informed decision and select the right dehumidifier for your home. Dehumidifiers have different price levels based on the manufacturer and the features available. Factors that impact the price of a dehumidifier include:
- Home size:
- Larger homes or areas with high humidity levels may require a more powerful whole-home dehumidifier, which can increase the cost. Your local Carrier dealer can assess your home’s square footage and humidity levels to help determine the appropriate size and capacity. Carrier whole-home dehumidifiers are available in 80- and 100-pint-per-day capacities, with the 80-pint model designed for small to mid-sized homes and the 100-pint model designed for mid-sized to large homes.
- Type of drainage: There are two types of systems—those that use a hose to drain by gravity, and others that use an internal or external pump. A pump may add to installation costs when gravity drainage is not practical.
- Energy efficiency levels: Higher-efficiency models tend to cost more than basic models upfront but can help reduce the electricity required to remove moisture. ENERGY STAR measures whole-home dehumidifier efficiency using Integrated Energy Factor (IEF), expressed as liters of moisture removed per kilowatt-hour.
- Existing system: Whole-home dehumidifiers can be attached to the ductwork of your existing system as a dehumidifier for AC unit integration or, in some cases, can work as a standalone dehumidifier. Carrier's Performance™ Whole-Home Dehumidifier (DEHXX) can be integrated with an existing HVAC system or installed as a standalone solution.
- Warranties: Warranties provide coverage for eligible repairs or parts, depending on the terms of the warranty or agreement. Carrier's Performance Whole-Home Dehumidifier includes a 5-year parts limited warranty.
Carrier Whole House Dehumidifier Cost Breakdown
The following factors help explain where a whole-home dehumidifier investment can vary. Actual pricing depends on the home, installation requirements, location and dealer.
| Cost factor | Typical consideration | Carrier example |
|---|---|---|
| Capacity | Higher moisture loads generally require greater capacity | 80 or 100 pints/day |
| Home size | Capacity should be matched to square footage and humidity load | 80 pints/day: small to mid-sized homes; 100 pints/day: mid-sized to large homes |
| Drainage | Gravity drainage can be simpler; a pump may be needed when gravity drainage is not practical | Varies by installation |
| Ductwork | Connecting to existing ductwork or creating additional ductwork can affect installation labor | Can be integrated with an HVAC system or installed independently |
| Efficiency | More efficient equipment can remove moisture with less electricity | Carrier models are ENERGY STAR® certified |
Carrier's current Performance™ Whole-Home Dehumidifier is available in 80- and 100-pint-per-day models and is ENERGY STAR® certified.
Whole House Dehumidifier Installation and Labor Costs
Whole house dehumidifier installation is best handled by a professional to ensure the system operates efficiently and correctly within your HVAC setup.
Your local Carrier dealer can ensure the unit is installed correctly and efficiently. They can assess your home’s specific needs and determine the best location for the dehumidifier. Installation costs can vary significantly because the technician may need to connect ductwork, route condensate drainage, install a pump, or make electrical or control connections. Other factors that affect labor costs include
- Geographical location: Labor costs vary across the United States. If you are searching for a "dehumidifier near me," local rates will apply.
- Location of the dehumidifier in your home: This impacts the amount of time it takes the technicians to complete the installation. Installing an HVAC dehumidifier in a garage or an easy-to-access utility closet is faster in comparison to an attic or crawl space.
- Equipment: Costs vary if you are purchasing an entirely new system or adding the dehumidifier to an existing HVAC unit.
- Drainage and electrical requirements: Additional drainage, a condensate pump, electrical work or controls can increase the total installation cost.
Jason Krieg, owner of Alamo Air Austin in Austin, TX, said the size of the home and the dehumidification capacity of the equipment are two major factors that influence whole-home dehumidifier costs. He cautions homeowners against choosing an undersized unit solely to reduce upfront installation expenses.
“Larger homes or spaces with higher humidity loads typically require higher-capacity equipment, which can increase the overall cost of the system,” Krieg said. “As indoor humidity levels decrease, it becomes more difficult for a dehumidifier to remove additional moisture efficiently. Having properly sized equipment with adequate capacity helps ensure the system can maintain comfortable humidity levels during periods of elevated moisture and high demand.”
Whole Home Dehumidifier Cost Savings
Investing in a whole home dehumidifier can provide long-term cost savings in several ways:
- Energy efficiency and reduced energy bills: Whole home dehumidifiers remove excess moisture from the air, which can improve comfort and may reduce the need to lower the thermostat to compensate for high humidity. However, actual energy savings vary based on climate, indoor humidity, equipment efficiency and how often the dehumidifier operates.
- Preservation of home furnishings and appliances: Excessive humidity can damage home furnishings and appliances. High moisture levels can cause wood to warp, upholstery to mold, and electronics to malfunction. By controlling humidity with a whole home dehumidifier, you can help protect your valuable investments and extend their lifespan.
- Avoidance of costly repairs due to moisture damage: Moisture can contribute to mold growth, wood damage and other moisture-related problems. By installing a whole home dehumidifier, you can help manage indoor humidity and reduce conditions that contribute to moisture-related damage.

Unlike portable units, whole-house dehumidifiers integrate with the HVAC system for consistent efficiency, potentially lowering cooling costs and protecting your home's structure.
The cost to have a whole-house dehumidifier installed typically ranges from $1,000 to $2,800 or more. This price includes both the unit and professional labor. Costs vary based on system capacity, brand, installation complexity, and whether you choose a high-end model with advanced features.
While a dehumidifier for AC unit integration does use electricity, it often can lower your overall energy bill. By removing moisture, the dehumidifier allows your air conditioner to run less frequently and at a higher temperature while maintaining the same comfort level, which improves overall system efficiency.
DIY installation is generally not recommended for whole house dehumidifier installation. Proper integration requires electrical work, drainage setup, and precise ductwork modifications. Hiring an HVAC professional ensures the warranty remains valid and the system operates safely and effectively.
