How can I prevent mold growth during summer?

Maintain your HVAC system to keep indoor temperatures in the low- to mid-70s and ensure it is extracting humidity effectively. Vent humid rooms like the kitchen and bathrooms with fans that exhaust moist air outdoors. Regularly inspect for leaks and seepage in the home and repair promptly.

How does summer weather contribute to indoor mold?

Summer high temperatures in many U.S. states are within the mold-preferred range of 77 to 86 degrees Fahrenheit. In addition, relative humidity often exceeds 60%, the EPA-recommended limit to inhibit mold, creating ideal conditions for mold growth.

How can my HVAC system help prevent mold?

A well-maintained HVAC system helps by maintaining cooler indoor temperatures and reducing indoor humidity. Changing the system air filter monthly during summer helps to reduce airborne mold spore count.

Why Summer Can Mean More Indoor Mold and What to do About It

Indoor Mold From Summer Heat Moisture and Consistent Condensation

Mold doesn't take a summer vacation. In fact, it's the time of year that provides ideal conditions to trigger dormant mold spores into active mode. Daily summer high temperatures in more than half the U.S. are within the mold-preferred range of 77 to 86 degrees, Fahrenheit. In about 40 states, relative humidity readings exceed 60%, the EPA-recommended upper limit to inhibit mold, for at least some portion of a typical day during June, July and August.

You can't do much about the outdoor climate that nurtures mold. However, it's possible to control the indoor environment to reduce the likelihood that mold will gain a foothold and contaminate your house. Here are some season-specific suggestions to prevent mold growth during a long, hot summer.

Your HVAC System Is Your Friend

A fully-functional, efficient HVAC system not only keeps you comfortable all summer, it's a vital ally to inhibit indoor mold growth.

Hot weather outdoors tends to push indoor temps up, too. Set your A/C thermostat to maintain temperatures in the low- to mid-70s to suppress mold growth. Keep indoor conditions consistently cool, even if you leave home for a few days.
Water vapor extracted by the A/C evaporator coil reduces indoor humidity that feeds mold. Make sure the air conditioner is operating up to specs by getting manufacturer-recommended annual preventive maintenance to support optimum humidity extraction.
Mold prefers stagnant conditions. Maximize cool HVAC airflow throughout the house by changing the system air filter every month all summer long. A fresh, high-quality pleated filter also helps reduce the airborne mold spore count.

Eliminate Other Moisture Sources

Indoor humidity equals the outdoor relative humidity plus the amount of extra water vapor added by activities such as cooking and bathing. Vent humid rooms such as the kitchen, bathrooms and laundry room with powered vent fans that exhaust moist air outdoors.
Keep up with home maintenance. Leakage into the attic during summer storms provides a perfect environment for mold growth. Make sure the roof is professionally inspected for leaks every three years. Also have any plumbing leaks or seepage repaired promptly.

Summer is a critical time for mold prevention in your home. The combination of high temperatures and increased humidity creates an environment where mold can thrive if left unchecked. But remember, you have the power to control your indoor environment and protect your home from mold contamination.
