Whole House Dehumidification



Florida's subtropical climate is beautiful, but it comes with a significant challenge - humidity. In the area, homeowners often find that their air conditioning system alone isn't enough to keep indoor humidity at comfortable and healthy levels. That's where a whole house dehumidification system becomes essential. Van Eddies Heating & Air Conditioning has been helping Orlando families breathe easier since 1999, and whole house dehumidification is one of the most effective investments you can make for indoor air quality and home comfort.

Understanding Your Home's Humidity Problem
Humidity levels above 60 percent create the perfect conditions for mold growth, mildew, and dust mites. In the metropolitan area, summer humidity regularly exceeds 80 percent, and even with air conditioning running, many homes struggle to maintain healthy indoor humidity levels. This happens because air conditioning alone removes some moisture, but it's designed primarily for temperature control, not humidity management.
You might be wondering whether your air conditioning should handle dehumidification naturally. The short answer is that it helps, but it's not enough. Here's why:
- AC cycles in mild weather: During spring and fall , outdoor temperatures are moderate but humidity remains high. Your air conditioner may not run frequently enough to remove moisture effectively.
- Oversized AC systems: If your cooling system is oversized for your home's square footage, it cools the space quickly and shuts off before removing adequate moisture.
- Efficiency vs. humidity control: Modern high-efficiency air conditioners are designed to cool quickly and cycle on and off efficiently. They're not optimized for extended runtime needed to dehumidify thoroughly.
- Seasonal challenges: Winter months can bring moisture issues too, especially in bathrooms and basements where warm showers and natural seepage create localized humidity problems.
A dedicated whole house dehumidification system runs independently of your AC, targeting humidity control specifically. This means your home stays comfortable and healthy year-round, not just during the hottest months.
When You Need More Than Air Conditioning
Every homeowner should understand the signs that your current system isn't managing humidity adequately. If you experience any of these issues, whole house dehumidification deserves serious consideration:
- Visible condensation: Water droplets forming on windows, mirrors, or cold water pipes indicate moisture in the air that your AC isn't removing.
- Musty or moldy odors: A damp, earthy smell often precedes visible mold growth. This is your sign that humidity levels are supporting mold development.
- Sticky or clammy feeling: Even when your home feels cool, you might notice your skin or clothes feel damp. This uncomfortable sensation means humidity is elevated.
- Allergy and respiratory symptoms: Increased sneezing, coughing, or asthma flare-ups often correlate with high indoor humidity supporting allergen growth.
- Paint or drywall damage: Peeling paint, warped drywall, or stains on ceilings and walls indicate persistent moisture problems.
- Mold spots in bathrooms or closets: Any visible mold growth shows that your current moisture control is insufficient.
- Musty basement or crawl space odors: Lower-level moisture problems often go unnoticed until they become serious.
- Humidity readings above 55 percent: If you've checked your home's humidity level with a basic hygrometer (available at any hardware store), readings consistently above 55 percent mean your system needs support.
climate makes these issues particularly common. The combination of heat, constant outdoor moisture, and the way our homes interact with the subtropical environment creates humidity challenges that straightforward air conditioning can't fully solve.
How Whole House Dehumidification Works
A whole house dehumidification system operates as an integrated component of your existing HVAC infrastructure. Understanding how it works helps you appreciate why it's such an effective solution.
The basic process:
Your whole house dehumidifier draws humid air from your home through your existing ductwork. As this air passes over cold evaporator coils, moisture condenses into liquid water - similar to how water forms on a cold glass on a humid day. The now-drier air travels back through your ducts and circulates throughout your home. The extracted water drains away through a condensate line, much like your air conditioning system handles drainage.
The key difference from standard air conditioning is that your dehumidification system can run on a schedule independent of temperature control. Even when your AC isn't actively cooling because the temperature is already comfortable, your dehumidifier continues removing moisture. This flexibility means you can maintain ideal humidity levels (between 35 and 50 percent) in every season.
Why integration with existing ductwork matters:
A whole house dehumidifier doesn't require new ducting or structural changes to your home. Van Eddies technicians integrate the unit with your current HVAC system, typically positioning it near your furnace or air handler. Your existing return air ducts pull humid air from your home, and existing supply ducts distribute the dried air back. This seamless integration means minimal installation disruption and maximum efficiency.
The placement of your dehumidification system significantly impacts performance. Your Van Eddies technician will evaluate your home's layout, existing ductwork configuration, and moisture problem areas to recommend optimal positioning. For most homes, placement in the mechanical closet or basement near the furnace works best, but every installation is slightly different.
Sizing Your Dehumidification System
Proper sizing is absolutely critical for whole house dehumidification. An undersized unit won't adequately control humidity, while an oversized system cycles on and off inefficiently and may over-dehumidify, creating uncomfortable dry conditions.
Sizing is measured in "pints per day" - the amount of moisture a system can remove in a 24-hour period. Your home's required capacity depends on several factors:
Square footage: Larger homes generally require larger dehumidification capacity. A 1,500-square-foot home needs different coverage than a 4,000-square-foot property.
Current humidity levels: The higher your home's baseline humidity, the larger the system needs to be. If your indoor humidity reads 75 percent and you want to reach 45 percent, you need substantial dehumidification capacity.
Local climate: subtropical environment means most homes need robust dehumidification capabilities compared to drier regions.
Air conditioning efficiency: How well your existing AC system removes moisture influences how much work your dehumidifier needs to do.
Occupancy and activities: Families that shower frequently, cook extensively, or do laundry in-home generate more moisture that needs removal.
Van Eddies uses a comprehensive assessment process to determine your home's exact dehumidification needs. Rather than simply applying a formula, our qualified technicians evaluate your specific situation - your home's size, your current humidity readings, your lifestyle patterns, and your comfort goals. This personalized approach ensures you get a system that delivers results without wasting energy on oversized capacity you don't need.
Installation Process and Integration
Installing a whole house dehumidifier is more straightforward than many homeowners expect, especially when you work with experienced professionals like Van Eddies. The process typically unfolds over one or two service visits.
Initial assessment:
Your technician visits your home to inspect your existing HVAC system, evaluate your ductwork, assess current humidity levels, and identify the best location for your dehumidifier unit. This assessment determines system sizing, placement, drainage solution, and electrical requirements. We'll answer all your questions about how the system operates and what results you can expect.
System selection:
Based on your home's specific needs, Van Eddies recommends an appropriately sized dehumidifier from reputable manufacturers. We discuss options with you, including efficiency ratings, warranty coverage, and expected performance.
Installation day:
Our technicians position your dehumidifier near your existing air handler or furnace. We connect the unit to your return air ductwork, so it draws humid air from your home's existing system. Fresh, dried air connects to your supply ducts for distribution throughout your home. We establish a proper condensate drain line, which typically runs to a floor drain, sump pump, or outside drain. If you don't have a nearby drain, we discuss safe drainage solutions. All electrical connections meet code requirements, and we ensure your system integrates smoothly with your existing thermostat and controls.
Testing and training:
Before we leave, we test your system to confirm it's operating correctly. We show you how to monitor humidity levels, explain any maintenance requirements, and answer questions about operation. You'll understand exactly what to expect and how your new system supports your home's comfort.
Most whole house dehumidifier installations take a single day, and Van Eddies schedules your appointment at times that work with your schedule. We're committed to being respectful of your home and your time.
Drainage Solutions for Your Dehumidifier
One practical aspect of whole house dehumidification that surprises many homeowners is the drainage requirement. Your dehumidifier removes significant amounts of moisture - potentially 20 to 50 gallons per day in humid climate during summer months. This water needs somewhere to go.
Ideal drainage options:
- Floor drain: If your mechanical closet or basement has a floor drain connected to your home's drainage system, this is the simplest solution. Your dehumidifier's condensate line runs directly to the drain.
- Sump pump: Many homes have sump pumps for water management. Connecting your dehumidifier's drain line to your sump pump basin works well and keeps water away from your foundation.
- Outdoor drain: We can run condensate lines to your exterior, discharging water away from your home's foundation and landscaping.
- Laundry sink or utility drain: If your dehumidifier is positioned near a utility sink, laundry tub, or similar drain, this provides an accessible drainage point.
What we avoid:
Some homeowners suggest running dehumidifier condensate into a bucket that you empty manually. While this technically works, it's inconvenient and prone to overflow when you forget to empty it. Van Eddies recommends permanent drainage solutions that require no ongoing attention.
During your installation, our technicians evaluate your home's drainage options and recommend the best solution for your specific situation. We ensure that water drains safely away from your home's foundation and doesn't create any secondary moisture problems.
Energy Impact and Operating Costs
A common question we hear is whether running a whole house dehumidifier will significantly increase your electricity bill. The answer depends on several factors, and understanding these helps you make an informed decision.
Dehumidifier efficiency:
Modern whole house dehumidifiers operate fairly efficiently compared to portable units. A properly sized system running continuously might add 300 to 800 watts of electrical draw, depending on the specific model and how hard it's working. To put this in perspective, that's comparable to running a few standard light fixtures continuously.
Seasonal operation:
You won't run your dehumidifier constantly year-round. In winter months, humidity naturally drops, and your system will cycle on and off as needed rather than running continuously. This reduces overall energy consumption compared to running 24/7 during summer months.
Interaction with air conditioning:
Here's an important consideration: adding proper dehumidification may actually reduce your air conditioning costs. When your AC doesn't have to work as hard at moisture removal, it cycles more efficiently. Some homeowners find that their total HVAC energy consumption stays similar or even decreases when they add dedicated dehumidification, because their AC system runs less frequently while still maintaining comfort.
Long-term value:
The energy cost of running a dehumidifier is typically offset by the benefits - protection of your home's structure from moisture damage, prevention of mold growth that could require expensive remediation, and health benefits from better indoor air quality. Think of it as insurance that protects your home while improving comfort.
Van Eddies can discuss expected operating costs based on your specific system and local electricity rates. We're committed to helping you understand the true cost-benefit of the investment.
Humidity Level Improvements You Can Expect
One of the most satisfying aspects of installing whole house dehumidification is the immediate, measurable improvement in your home's humidity levels.
Realistic expectations:
Most homes benefit from humidity reduction to the 40 to 55 percent range - the zone where mold growth becomes unlikely, dust mites decline significantly, and comfort improves noticeably. If your home currently reads 75 to 80 percent humidity, you can expect to reach these healthier levels within a few days to a week of operation, depending on system capacity and seasonal conditions.
Seasonal variation:
Your humidity levels will naturally vary between seasons. Summer months in typically require your dehumidifier to work harder, while winter months allow it to run less frequently. This is normal and expected. Even in winter, when outdoor humidity drops, your dehumidifier cycles on as needed to maintain healthy indoor levels.
Comfort and health benefits appear quickly:
Many homeowners notice improvements almost immediately - sticky air becomes fresh and crisp, musty odors disappear within days, and allergy symptoms often diminish. These aren't imaginary benefits; they're direct results of moisture control that your body recognizes right away.
Routine Maintenance for Your Dehumidification System
Keeping your whole house dehumidifier operating efficiently requires minimal but important maintenance. The good news is that most of this maintenance is straightforward.
Filter replacement:
Your dehumidifier has an air filter that prevents dust and particles from damaging the cold coils where moisture removal happens. This filter needs replacement typically every 3 to 6 months, depending on your home's dust levels and how frequently the system runs. Replacing this filter is simple enough for most homeowners, but Van Eddies can include it in routine maintenance visits.
Coil cleaning:
Over time, the evaporator coils where moisture condenses can accumulate dust and debris. Annual professional coil cleaning, typically performed during your seasonal tune-up, keeps your system operating at peak efficiency. Clean coils remove moisture more effectively and use less energy.
Condensate drain maintenance:
Your dehumidifier's drainage line occasionally needs attention to prevent blockage. If your drain line runs to a floor drain or outside, checking it seasonally ensures water flows freely. Van Eddies includes drain inspection and cleaning in maintenance visits.
System check-up:
Annual inspection of your dehumidification system - checking electrical connections, verifying proper operation, and confirming humidity control - takes an hour or less but extends system lifespan and prevents problems. Many homeowners bundle this with their air conditioning tune-up for comprehensive HVAC care.
The good news is that Van Eddies can incorporate whole house dehumidifier maintenance into your regular HVAC service plan. Rather than juggling separate appointments, we handle everything during your annual tune-up visit. This keeps your entire system - heating, cooling, and dehumidification - operating at peak performance.
Common Issues in High-Humidity Climates
Living in means understanding the specific moisture challenges that high-humidity environments create. Many homeowners experience problems that directly benefit from whole house dehumidification.
Mold growth:
Mold thrives in moisture above 55 percent humidity. In the area, mold growth on bathroom ceilings, around window frames, and in closets is incredibly common. While you should address any visible mold with appropriate cleaning, preventing future growth requires humidity control. A whole house dehumidifier stops mold from developing in the first place.
Dust mite proliferation:
Dust mites don't just cause allergies; they reproduce explosively in humid environments. Reducing humidity to below 50 percent dramatically slows dust mite population growth, providing relief for family members with allergies or asthma.
Moisture damage to structures:
High indoor humidity causes paint to peel, drywall to warp, wood to swell, and metal to corrode. Over years, this moisture damage becomes expensive to repair. Homeowners who maintain proper humidity levels avoid these costly problems entirely.
Condensation and window damage:
When warm, humid indoor air meets cool windows on air-conditioned homes, condensation forms on glass. This moisture eventually damages window frames and sills. Proper dehumidification prevents this problem.
Odor problems:
Musty, moldy odors develop when humidity stays high. These aren't just unpleasant - they indicate an environment where mold and mildew are actively growing. Dehumidification eliminates both the odors and the underlying moisture that causes them.
Electronics and humidity:
High humidity affects electronics, promoting corrosion and reducing lifespan. Keeping humidity controlled protects your home's electrical systems, computers, and appliances.
The humidity challenges specific to and the surrounding areas make dehumidification not just a comfort upgrade but a practical necessity for home protection. Van Eddies has installed whole house dehumidifiers in thousands of Orlando-area homes, and homeowners consistently report that humidity control was one of the best investments they made for their home's long-term health.
Health and Comfort Benefits of Proper Dehumidification
Beyond the structural protection that humidity control provides, the health and comfort improvements are often the most immediately noticeable benefits of whole house dehumidification.
Respiratory health:
High humidity supports mold growth and dust mite populations, both significant respiratory allergens. Homeowners with asthma, allergies, or other respiratory conditions often experience noticeable improvement when humidity drops to healthy levels. Children, elderly family members, and pets with respiratory sensitivity frequently show the most dramatic health improvements.
Reduced allergy symptoms:
If family members suffer from year-round allergies rather than just seasonal allergies, indoor humidity might be the culprit. By controlling moisture, you reduce the indoor allergen load substantially. Many families report fewer sneezing episodes, less congestion, and reduced need for allergy medications after adding dehumidification.
Better sleep quality:
High humidity makes sleeping uncomfortable - you feel sticky, your skin feels clammy, and the air feels heavy. Many people sleep significantly better when their bedroom maintains comfortable humidity levels. Improved sleep has cascading benefits for overall health and daytime functioning.
Skin and comfort:
Uncomfortably high humidity affects your skin, making you feel perpetually damp and uncomfortable. Proper humidity levels feel noticeably better on your skin and allow your body's natural cooling mechanisms to work more effectively.
Reduced dust and particles:
Lower humidity reduces dust mite populations and helps control airborne particles. This means cleaner air, less frequent dusting, and fewer particles in your home's environment.
Safety and comfort for your family:
Van Eddies' core commitment is "be comfortable with quality" - and whole house dehumidification delivers exactly that. It's an investment in your family's comfort and health that you notice every single day.
Choosing Professional Installation Over Portable Units
Some homeowners consider portable dehumidifiers as a budget-friendly alternative to whole house systems. While portable units have a place in specific situations, they fall short for comprehensive home moisture control.
Limitations of portable dehumidifiers:
- Single-room coverage: A portable unit treats only the room it occupies, leaving the rest of your home humid.
- Constant maintenance: You must empty water collection buckets regularly or run a drain line, creating ongoing chores.
- Inefficiency: Portable units use more energy per pint of moisture removed compared to whole house systems.
- Noise: Most portable dehumidifiers create noticeable noise, which can be annoying in bedrooms or living spaces.
- Aesthetic issues: Large portable units take up floor space and look industrial in your home.
- Limited capacity: Even large portable units remove less moisture than whole house systems.
Portable units might make sense as a temporary solution for a specific area during particularly humid weather, but they're not practical for year-round whole home dehumidification. If you've been frustrated with a portable unit, switching to whole house dehumidification will feel like a revelation.
