How to Reduce Allergens with Your Florida HVAC System

If you live in Florida, you know that allergies can hit hard year-round. Between high humidity, seasonal pollen, pet dander, and even mold growth, it’s tough to keep indoor air clean and comfortable. Thankfully, your HVAC system can be one of your best defenses against allergens — if it’s properly maintained and equipped.

Here are some proven ways to use your Florida HVAC system to reduce allergens in your home.

Upgrade to a High-Quality Air Filter

Standard filters only capture large particles like dust. To fight allergens, look for filters with a MERV rating of 8–11 or higher. These can trap pollen, pet dander, mold spores, and other microscopic irritants common in Florida homes.

Tip: Replace filters every 30–60 days in Florida’s hot, humid climate to prevent buildup and keep airflow strong.

2. Keep Humidity Under Control

Florida’s humidity doesn’t just make it feel hotter — it also encourages mold and dust mites. To combat this:

• Run a dehumidifier or use an HVAC system with built-in humidity control.
• Keep indoor humidity between 40–50%.
• Schedule regular maintenance to ensure your system is draining properly.

3. Clean and Seal Ductwork

Dust, pet hair, and mold spores can collect inside leaky or dirty ducts, spreading allergens throughout your home. Professional duct cleaning and sealing can significantly improve indoor air quality and reduce allergy flare-ups.

4. Invest in an Air Purifier or UV Light

Adding a whole-home air purifier or UV light system to your HVAC can help kill bacteria, mold spores, and viruses before they circulate. This extra layer of protection is especially valuable for allergy and asthma sufferers.

5. Schedule Regular HVAC Maintenance

Routine maintenance is key to keeping allergens under control. During an AC tune-up, a technician will:

• Clean coils and components
• Check for mold or standing water in the system
• Ensure filters and drains are working properly

Regular service helps your system run more efficiently while protecting your indoor air quality.
