The best way to prevent mold and mildew in a humid Florida home is to keep indoor relative humidity (RH) below 60%. A combination of dehumidification, filtration, ventilation, and regular HVAC maintenance makes that possible. At The Green Air Group, we help homeowners in Freeport, FL, put those solutions to work.
Florida’s high humidity lingers year-round, so excess moisture is a persistent problem in many coastal homes. It can lead to discomfort, a musty house, pest problems, and even mildew and mold growth.
High Humidity, Mold, and Mildew in Florida Homes
Outdoor RH along the Florida Panhandle often climbs above 90% overnight and in the early morning. Even on summer afternoons, it frequently stays at or above 60%. With an indoor RH above 60%, you’re at much higher risk of mildew, mold, dust mites, and other issues.
Running your AC does help, as some dehumidification is a byproduct of cooling your home. However, in Florida, cooling alone frequently can’t keep RH at a safe threshold. Maintaining the optimal 40% to 50% range for comfort through AC alone is often difficult.
The Potential Negative Impact on Your Family’s Health
Mildew and mold are fungi. Mildew tends to grow only on surfaces, such as your shower curtain. Mold, on the other hand, can penetrate surfaces, including sheetrock and wood.
Mildew can cause musty odors and exacerbate allergies and asthma. The negative impact of mold can be much more serious, especially for children and seniors. Prolonged exposure has been linked to asthma development in children and to other long-term respiratory conditions.
- Sleep disruptions
- Respiratory inflammation
- Itchy eyes and skin
- Headaches and brain fog
- Lung infections in high-risk individuals
How to Combat Mildew and Mold
Moisture control is key to healthy air quality in Florida. It often begins with seasonal HVAC maintenance. You may also need to upgrade filtration, ventilation, and dehumidification to improve your comfort and protect your family’s health.
- Seasonal HVAC maintenance
- Whole-home dehumidifiers
- High-efficiency HVAC filters
- Whole-home air purifiers
- Energy recovery ventilators (ERVs)
- Ultraviolet (UV) light systems
Seasonal HVAC Maintenance
Regular tune-ups help your AC remove moisture the way it should. During a maintenance visit, our technicians can clean the evaporator coil, clear the condensate drain line, and check your filter. A clean, clear system is less likely to harbor microbial growth or circulate musty air through your home.
Whole-Home Dehumidifiers
Keeping indoor RH below 60% is key to preventing mold and mildew in Florida homes. At lower levels, the fungi struggle to grow. If you can’t maintain a lower RH through air conditioning alone, we recommend a whole-home dehumidifier.
Whole-home dehumidifiers work with your ductwork to remove moisture from the air throughout your home. That way, they not only enhance your comfort and air quality but also help your cooling system run more efficiently. We can pair one with a compatible smart thermostat so you can control temperature and humidity through one interface.
High-Efficiency HVAC Filters
Your HVAC filter protects your equipment and promotes cleaner air. The higher its minimum efficiency reporting value (MERV), the better the filtration. You should choose the highest MERV rating your system can handle, as a filter that’s too restrictive can reduce airflow and efficiency.
Whole-Home Air Purifiers
For even better air filtration, consider a whole-home air purifier. An in-duct air purification system can filter all the air in a home multiple times an hour, even while you sleep.
Many air purifiers in Freeport have a high-efficiency particulate air (HEPA) filter to trap over 99% of particulates. Particulates include dust, mold spores, pollen, and pet dander. Many also include activated carbon to adsorb odors and airborne chemicals.
Energy Recovery Ventilators (ERVs)
Many modern homes have tight building envelopes for high energy efficiency. The downside is that too little fresh air comes in. That can lead to higher concentrations of mold spores and other pollutants.
ERVs are mechanical ventilation systems that deliver a steady supply of fresh air. In humid climates, they also remove some moisture from incoming air, which eases the load on your AC.
UV Light Systems
UV lamps emit germicidal light that neutralizes bacteria, viruses, and other airborne pathogens. There are two types of UV lights commonly used in Florida homes. Coil-based sanitizers prevent microbial growth on AC and heat pump evaporator coils. In-duct UV lights can improve air quality by lowering the presence of mold spores and viruses.
