Indoor Air Quality Concerns in Florida Homes: What Buyers Should Know
When buying a home, here in Florida, one of the most overlooked factors is the quality of the air inside the home. Our warm, humid climate can contribute to a range of indoor air quality (IAQ) issues that affect your comfort, health, and long-term enjoyment of the property. We believe that understanding and evaluating the air quality in a home is important in making a well informed purchase and we have included information in this article to help you with what you may need to know.
Common Indoor Air Quality Problems in Florida Homes
Mold and Mildew – Due to Florida’s high humidity, mold is one of the most common IAQ concerns. It can grow in HVAC systems, behind walls, in attics, and under flooring, often undetected until it becomes a major problem.
Poor Ventilation – Many older homes in Florida were built with limited ventilation. Without adequate airflow, moisture and airborne contaminants build up indoors.
HVAC Contamination – Dirty air ducts, filters, or coils can circulate dust, mold spores, and allergens throughout the home. In some cases, pests or rodents may have entered the ductwork.
Off-Gassing from Materials – Flooring, cabinetry, and older furniture may release volatile organic compounds (VOCs), especially if the home has been closed up for long periods.
Pest Droppings and Debris – Cockroaches, rodents, and other pests leave behind waste that can degrade air quality and trigger respiratory problems.
Excess Humidity – A home with poor moisture control may have consistently high indoor humidity, creating a breeding ground for mold and dust mites.
Health Risks Associated with Poor Indoor Air
Poor IAQ isn’t just an inconvenience—it can have serious health implications, particularly for individuals with allergies, asthma, or respiratory conditions. Common symptoms include:
Allergic reactions (sneezing, itchy eyes, skin rashes)
Asthma attacks or increased asthma symptoms
Fatigue and headaches
Respiratory infections
Eye, nose, and throat irritation
How a Home Inspection Can Help
Before purchasing a used home, a comprehensive inspection can reveal air quality risks and offer recommendations to improve indoor conditions. Items below should be considered:
Evidence of mold, water intrusion, or high humidity
Condition of the HVAC system and ductwork
Adequacy of ventilation in kitchens, bathrooms, and attics
Presence of odors, visible stains, or signs of pest infestations
Window and door seals that may affect indoor air exchange
We may also recommend specialized indoor air quality testing when necessary, especially if there are known sensitivities or c
concerns from the buyer.
Tips for Improving Air Quality in a Florida Home
If you're considering buying a home in Florida, or have recently moved in, here are steps you can take to improve indoor air quality:
Install a Dehumidifier – Helps maintain indoor humidity below 60% and reduces mold growth.
Maintain the HVAC System – Regularly change filters, clean ducts, and schedule routine maintenance.
Use Exhaust Fans – Ventilate bathrooms, kitchens, and laundry rooms to remove excess moisture.
Seal Air Leaks – Properly seal doors and windows to prevent outdoor pollutants from entering.
Use Air Purifiers – Especially useful for removing allergens, dust, and VOCs.
Keep the Home Clean – Reducing dust, vacuuming regularly, and minimizing clutter can limit airborne pollutants.
Bottom Line
Your home should be a safe and healthy place to live. Poor indoor air quality can impact your well-being and lead to unexpected repair costs.
