Living in Central Florida means dealing with humidity that can sometimes feel like you’re walking through soup. As any local resident knows, our humidity levels regularly climb above 80% during the hot months, making our already warm climate feel downright oppressive. But there’s good news—your air conditioning system can be a powerful ally in the fight against indoor moisture when properly used and maintained.
Here in Winter Garden and throughout Orange, Lake, Seminole, and Osceola counties, we at Rich’s AC have been helping homeowners tackle humidity problems for over 20 years. The unique climate challenges of our region require specific approaches to humidity control that might differ from advice you’d get elsewhere in the country.
On those muggy summer days when stepping outside feels like walking into a steam room, your home should be a cool, dry sanctuary. But when indoor humidity creeps up, even a well-cooled home can feel clammy and uncomfortable. Let’s explore how your air conditioning system can be optimized to keep your Central Florida home comfortable and humidity-free.
Understanding Humidity and Your AC System
Before diving into solutions, it’s important to understand how your air conditioner naturally removes humidity. When warm, humid air passes over your AC’s cold evaporator coil, moisture in the air condenses into water droplets—just like dew forming on a cold glass. This water then drains away through your condensate line.
While all air conditioners remove some humidity during normal operation, standard systems in Florida often struggle to keep up with our extreme moisture levels. Most AC units are primarily designed to cool rather than dehumidify, which is why additional strategies are often needed in our climate.
High indoor humidity isn’t just uncomfortable—it creates a perfect environment for mold growth, dust mites, and can even damage wooden furniture and fixtures over time. The EPA recommends keeping indoor humidity between 30% and 50%, but in Florida, achieving the lower end of that range often requires deliberate effort.
Signs Your Home Has Excessive Humidity
How can you tell if your home has humidity issues? Look for these common indicators:
Water condensation on windows and glass surfaces, especially during cooler months, often signals excess moisture in your home. You might notice a musty smell, particularly in less ventilated areas like closets or bathrooms. Mold spots appearing on walls, especially in corners or behind furniture, are clear warning signs of moisture problems.
If you feel sticky or clammy even when your air conditioner is running, that’s your body telling you humidity levels are too high. Wood floors or furniture swelling, warping, or feeling damp to the touch indicates moisture absorption. Allergies or respiratory issues worsening indoors could be related to mold or dust mites thriving in humid conditions.
Optimizing Your Existing AC System for Humidity Control
If you’re dealing with high indoor humidity, there are several ways to improve your existing system’s performance:
First, ensure your AC is properly sized. Many Florida homes have oversized units that cool quickly but don’t run long enough to adequately remove humidity. These short cycles, what we call “short-cycling,” cool your home but leave it feeling clammy. During our home assessments throughout Winter Garden and Orlando, we frequently identify this as a primary cause of humidity problems.
Regular maintenance is crucial. Dirty coils can’t effectively condense moisture, and clogged condensate lines prevent proper drainage. Our maintenance plans include thorough coil cleaning and condensate line checks to ensure optimal dehumidification.
Consider adjusting your fan settings. Running your fan continuously (“ON” setting) can actually reintroduce moisture back into your home as water on the coil evaporates. Instead, use the “AUTO” setting so the fan only runs during cooling cycles.
Smart thermostats can help manage humidity by providing more precise temperature control and in some cases, humidity monitoring. Modern systems from brands we install can be set to optimize for both temperature and humidity levels.
Dedicated Dehumidification Solutions
Sometimes optimizing your existing system isn’t enough, especially in Florida’s challenging climate. Here are effective supplemental options:
Whole-home dehumidifiers work alongside your AC system to remove moisture without overcooling your space. They’re particularly effective during those mild but humid days common in Central Florida spring and fall seasons, when your AC might not run long enough for effective moisture removal.
Variable-speed HVAC systems adjust their output based on your home’s needs, allowing for longer, more efficient run times that remove more humidity. These systems maintain more consistent temperatures while continuously filtering moisture from the air.
For specific problem areas like basements, Florida rooms, or enclosed patios, portable dehumidifiers can be an effective targeted solution. Just be sure to regularly empty the water collection tank or set up continuous drainage.
In extremely humid spaces or for homes with specific needs, specialty systems like desiccant dehumidifiers might be appropriate. These use special materials to absorb moisture and can work well in spaces where traditional systems struggle.
Ventilation Strategies for Moisture Control
Proper ventilation plays a crucial role in humidity management, especially in moisture-generating areas of your home:
Bathroom exhaust fans should always be used during showers and for 15-20 minutes afterward. Many Central Florida homes we service have inadequate bathroom ventilation, allowing shower steam to spread throughout the house.
Kitchen range hoods vented to the outside (not recirculating models) help remove cooking moisture. Cooking, especially boiling water, releases significant amounts of humidity into your home.
Ensure your dryer vents properly to the outside and check for leaks or blockages. A poorly vented dryer can release gallons of water vapor into your home with each load of laundry.
In Florida’s climate, it’s important to understand that opening windows, especially during humid seasons, often brings more moisture in rather than letting it out. This differs from advice you might hear from northern states.
Common Humidity Problem Areas in Central Florida Homes
Through our years serving Winter Garden, Windermere, Winter Park, and Orlando, we’ve identified several common problem areas specific to Florida homes:
Florida rooms and enclosed patios often suffer from inadequate insulation and conditioning, creating perfect conditions for humidity problems. These spaces typically have more windows and glass doors, which can develop condensation issues.
Newly constructed homes in rapidly growing areas like Horizon West or Lake Nona sometimes trap construction moisture in walls and slabs. This can cause elevated humidity levels for the first year or two of occupancy.
Older historic homes in Winter Park or downtown Orlando neighborhoods often lack adequate vapor barriers and modern insulation, making them more vulnerable to outside humidity infiltration.
Homes near lakes, particularly in the Chain of Lakes area or around Lake Apopka, frequently experience higher ambient humidity levels that can challenge even well-functioning AC systems.
Maintenance Tips for Optimal Humidity Control
Regular maintenance is essential for keeping your system working effectively against Florida’s humidity:
Change air filters regularly. Clogged filters restrict airflow, reducing your system’s ability to remove moisture. In Central Florida’s dusty conditions, filters may need changing more frequently than manufacturer recommendations.
Have your condensate line cleaned regularly to prevent clogs that can cause water backup and potential moisture damage. Our preventative maintenance plans include this critical service.
Schedule professional coil cleanings annually. Central Florida’s oak pollen and outdoor conditions can quickly dirty coils, reducing their effectiveness at condensing moisture.
Check and seal duct leaks. In humid attic spaces common in Florida homes, leaky return ducts can pull in moisture-laden air, compromising your system’s dehumidification ability.
Have your refrigerant levels checked. Low refrigerant not only reduces cooling efficiency but significantly impairs your system’s ability to remove humidity.
