Indoor Air Quality Testing

What is Indoor Air Quality Testing?

Indoor air quality testing is a whole-home look at the air rather than a single contaminant. Where a mold test targets mold and a radon test targets radon, IAQ testing characterizes the broader picture: airborne mold spores and their species mix, particulate load, relative humidity, and the ventilation and HVAC conditions that determine how well a home clears its own air. We take air samples in the primary living areas plus an outdoor reference, measure temperature and humidity, and evaluate the HVAC system, filtration, and ventilation that drive indoor air exchange. Samples go to an independent accredited laboratory; the report puts your indoor readings next to the outdoor baseline so elevations are meaningful and explainable. Because the building-systems review and the lab work happen together, the report does not just say the air is off — it points to why, whether that is a damp cavity, a filtration gap, an under-ventilated room, or a moisture source.

When You Need It

When occupants have symptoms with no single obvious cause, after a renovation or new flooring and furnishings that may off-gas, when a home is tightly sealed for energy efficiency and feels stuffy, before or after moving into an older property, or simply for a baseline if someone in the household is medically vulnerable. IAQ testing is also the right first step when you are not sure which specific test you need — it characterizes the whole picture and points to the targeted test (mold, radon, lead, or moisture) that the readings actually justify.

Signs to Watch For

• Occupant symptoms with no single obvious cause
• A recent renovation, new flooring, or new furnishings and a stuffy feeling
• A tightly-sealed, energy-efficient home with poor air exchange
• A medically vulnerable household member and a desire for a baseline
• Uncertainty about which specific test (mold, radon, lead) you actually need
• Lingering odors that ventilation alone does not clear
