Air conditioners are a staple appliance to keep our homes cool when outdoor temperatures rise. Here's what to consider to ensure your unit is promoting healthy indoor air quality and not negatively impacting it.

As most of us are aware, the Earth continues to get warmer; summers are longer and hotter and likely to become even warmer.

For central systems, this can even compromise the pressure of the building, creating a negative interior pressure that pulls in moisture from the outdoors, he explained.
