How Heat and Humidity Affect Indoor Air Quality during the Summer Months

July 14, 2015

Depending on which region you live in, the summer months can bring warm humid air or hot dry air. Both of these conditions can have harmful effects on your indoor air quality.

Mold requires moisture or water to grow. Unfortunately, air conditioning units provide just the right amount of moisture for mold. Check for any standing water or moisture inside your unit and have your system serviced if there is a chronic moisture build up.

High humidity levels can lead to mold growth. Humidity levels above 60% pose a threat to your indoor air quality. If you live in an area where humidity levels are high during the summer months you may want to purchase a Home Air Check Test to determine if you have any active mold growth. This test will provide you with a detailed report that will inform you of the presence of active mold, as well as many other volatile chemicals, in your home air.

Tips on how to keep the temperature and humidity of your home comfortable:

  • During the summer months, an ideal indoor temperature is anywhere from 73 °F to 79°F. Your air conditioner and/or opening the windows when it’s cooler can keep your home at a comfortable temperature.
  • Keep your home’s relative humidity around 50% for optimal comfort and to limit mold growth. A dehumidifier can help you to achieve comfortable humidity levels indoors. Many new air conditioning units have built in dehumidifiers.
  • Have your air conditioning unit and air ducts cleaned and serviced regularly. In especially humid conditions, mold can make its way inside your home. The last thing you want to do is blow air throughout your home that has been contaminated with mold spores.

Your air ducts need to be inspected regularly to determine whether or not a professional cleaning is warranted. If there are any signs of mold growth, a professional HVAC air duct cleaning service will need to carefully clean out your ducts without further contaminating your home air by sending airborne spores indoors or by using harsh cleaning solvents.

During hot and humid months protect your home air by eliminating conditions optimal for mold growth. If you detect a musty odor in your home while running your air conditioner, check for sources of moisture in your AC unit, ducts, or other places moisture might accumulate and consider testing your home for mold.
