Radon and Indoor Air Quality: What Homeowners Should Know

January 19, 2026

Understanding Radon and Its Connection to Your Home

Radon is a naturally occurring gas that can seep into homes from the surrounding soil, and it's worth understanding as part of a broader conversation about indoor air quality. Old Glory Air Conditioning and Heating shares what homeowners should generally know about this topic.

What Radon Actually Is

Radon is a naturally occurring, colorless, odorless gas that forms from the natural decay of uranium found in soil and rock, and it can enter homes through foundation cracks, gaps around pipes, or other openings connecting to the ground below.

Why Radon Levels Vary So Much by Location

Radon levels vary significantly based on local geology, meaning some areas naturally have higher radon potential than others. Testing is the only reliable way to know your specific home's radon levels, since it can't be seen, smelled, or tasted.

How Radon Testing Works

Radon testing typically involves a specialized test kit placed in the lowest livable level of your home for a set period, after which the results indicate the radon concentration present, measured in a standard unit specific to radon measurement.

The Connection Between Radon and Ventilation

While radon mitigation, if needed, typically involves a dedicated system separate from your standard HVAC equipment, overall home ventilation can play a role in how radon and other soil gases behave within your living space.

Why Testing Matters Regardless of Home Age

Both older and newer homes can have radon issues, since the presence of radon relates more to local soil conditions and how a specific home was constructed than to the age of the structure itself.

What Happens If Elevated Radon Levels Are Found

If testing reveals elevated radon levels, a radon mitigation system, typically involving a vent pipe and fan system, can be installed to redirect radon gas away from your home before it accumulates indoors.

Radon Mitigation as a Specialized Service

Because radon mitigation involves specific techniques different from general HVAC service, this work is typically performed by a specialized radon mitigation contractor rather than a standard heating and cooling company.

How This Fits Into Overall Indoor Air Quality

While radon is addressed through specialized mitigation rather than standard HVAC equipment, being aware of radon as part of your overall indoor air quality picture rounds out a homeowner's understanding of the various factors affecting their home's air.

Getting Testing Information for Your Area

If you're curious about radon levels in your specific area, your local health department or environmental agency can typically provide general information about regional radon potential and testing resources.
