AC Humidity Control

How Your Air Conditioner Affects Indoor Comfort

In South Florida, managing indoor humidity is just as important as cooling your home. While air conditioners are designed to lower the temperature, they also play a key role in reducing moisture from the air.

When humidity levels are too high, your home can feel warm, sticky, and uncomfortable, even when the thermostat says otherwise.

How Your Air Conditioner Reduces Humidity

Your air conditioner removes humidity as part of the cooling process:

• Warm, humid air passes over cold evaporator coils
• Moisture condenses on the coils once the air drops below the dew point
• Condensed water drains away through the system
• Cooler, drier air circulates through your home

This process helps maintain comfort, but it relies on proper system sizing, adequate airflow, and regular maintenance.

What Is the Ideal Indoor Humidity Level?

For most homes, the ideal indoor humidity level is between 30% and 50%.

• Above 50%: Increased risk of mold, mildew, and discomfort
• Below 30%: Dry air, irritated sinuses, and static electricity

South Florida homes often struggle with excess humidity, especially during long cooling seasons.

Why Your Home Feels Humid Even with the AC Running

If your AC is running but humidity remains high, common causes include:

• Oversized air conditioner (short cycles don’t remove enough moisture)
• Dirty evaporator coils
• Clogged condensate drain lines
• Improper airflow
• Aging or inefficient equipment

An oversized system is one of the most frequent humidity issues we see—it cools the home too quickly without running long enough to dehumidify properly.

Problems Caused by Excess Indoor Humidity

High humidity levels can lead to more than discomfort:

• Mold and mildew growth
• Buckling wood floors
• Musty odors
• Increased allergy and asthma symptoms
• Reduced AC efficiency
• Condensation around vents or windows

Lowering humidity helps protect both your home and your health.

Can a Dehumidifier Help?

In homes with persistent humidity issues, a whole-home or portable dehumidifier may be recommended. Dehumidifiers work alongside your air conditioner to remove excess moisture more effectively.

They are especially helpful if:

• Your home struggles to stay below 50% humidity
• You have allergies or asthma
• Mold or mildew has been an issue
• Your AC system is properly sized but still can’t keep up with humidity

Reduce Humidity with Regular AC Maintenance

Routine air conditioner maintenance helps ensure your system removes humidity effectively by:

• Keeping evaporator coils clean
• Ensuring drain lines are clear
• Maintaining proper airflow
• Improving overall system efficiency

Regular maintenance also helps lower energy costs and extend the lifespan of your AC system.
