Stop Mold Before It Starts

As temperatures and humidity rise during the summer months, homeowners should pay close attention to indoor moisture levels and HVAC settings to help prevent mold growth.

Warm air combined with excess humidity creates the ideal environment for mold to develop — especially in areas with poor airflow or excess condensation. Fortunately, there are several simple ways homeowners can reduce the risk.

One of the most important steps is keeping your thermostat at a reasonable temperature. While it may be tempting to raise the temperature significantly to save money on electricity, excessively warm indoor conditions can increase humidity and create an environment where mold thrives.

Another common mistake is leaving the AC fan set to “ON” instead of “AUTO.” When the fan runs continuously, moisture collected on the evaporator coil may not drain properly and can circulate humidity back into the home.

Homeowners should also avoid closing supply vents in certain rooms in an attempt to redirect airflow. Restricting airflow can lead to condensation buildup around vents, walls, and ceilings, increasing the risk of mold growth.

Signs of excess moisture may include:

• musty odors

• condensation on windows or vents

• discoloration on walls or ceilings

• increased indoor humidity

If mold becomes a serious issue, professional remediation can be expensive. That’s why preventative maintenance and proper HVAC operation are some of the best ways to protect both your home and your indoor air quality.

Taking a few preventative steps now can help homeowners avoid costly repairs and maintain a healthier living environment all summer long.
