Tips for reducing home humidity: use exhaust fans, air circulation, AC, HVAC maintenance, dehumidifier

Summer in Myrtle Beach means beach days and sunny weather, but the close proximity to the ocean also means dealing with high humidity. Humidity levels above 60% can make your home uncomfortable, damage your belongings, and negatively affect your health.


In this article, we explore the warning signs of high humidity levels in your home and five simple ways to help combat it.

Signs of High Humidity

1. Musty odors

One of the most common indicators of high humidity in your home is a damp, musty smell. These smells most often occur in bathrooms, laundry rooms, closets, and crawlspaces where moisture tends to accumulate.

2. Condensation on surfaces or windows

If you notice water droplets forming on your windows, mirrors, pipes, countertops, and other cool surfaces, it could be a sign that your indoor humidity levels are high. Persistent condensation can eventually lead to water damage and mold growth.

3. Warped floors or walls

Excess moisture in the home can be absorbed by wood flooring, trim, cabinets, and even drywall. Over time, this can cause floors to buckle, doors to stick, paint to peel, and walls to warp.

4. Visible mold or mildew growth

Damp conditions create the perfect environment for mold and mildew to thrive. If you notice black, green, or white spots around windows, ceilings, bathrooms, and HVAC vents, you likely have a moisture problem in your home.

5. Physical sickness symptoms

High humidity can cause poor indoor air quality which makes allergy and asthma symptoms worse. Coughing, congestion, headaches, fatigue, irritated eyes, or respiratory discomfort are common occurrences with excess humidity in your home.

Tips for Reducing Humidity

1. Use exhaust fans

Running exhaust fans in your bathroom while showering, and in your kitchen while cooking helps remove moist air before it spreads throughout the rest of the home.

2. Increase air circulation

Having good airflow in your home prevents moisture from settling in one area. To improve air circulation, open interior doors, use ceiling fans, and place furniture slightly away from the wall.

3. Run your air conditioner

In order to effectively cool your home, your air conditioning system works to remove moisture from the air. Running your A/C consistently during the summer keeps you cool and improves your indoor air quality.

4. Maintain your HVAC system

Hot summers and high humidity can take a toll on your HVAC system. Performing regular maintenance ensures your system operates properly and efficiently. CTC makes AC maintenance easy by offering the HVAC Preventative Maintenance program.

5. Run a dehumidifier

If your home consistently struggles with high humidity, a whole-home dehumidifier can make a significant difference. Dehumidifiers help prevent mold growth, reduce musty odors, and improves overall indoor air quality by removing excess moisture from your home.
