Indoor air quality testing in Bucks County and Philadelphia

Measuring the air you cannot see anything wrong with

Indoor air testing exists for the situation where nothing looks wrong. No stain, no visible growth, and somebody in the house is still reacting. Air sampling counts what is actually suspended in the air and compares it against an outdoor control taken the same day, which is the only way the indoor number means anything, since spore levels move with the weather. A result well above outdoors says there is a source inside, even when a mold inspection has not turned up a patch yet.

What indoor air quality testing shows

What the air will tell you that the walls will not

What a sample settles when there is nothing visible to point at.

Whether the indoor spore level is genuinely above the outdoor level that day.

Which species are airborne, not just that something is.

Whether a room that feels wrong is measurably different from the rest of the house.

Whether the heating and cooling system is spreading it around.

A number to compare against after work is finished, rather than a judgement call.

Evidence for a household where one person reacts and nobody else does.

Mold in air ducts and how it spreads through a house

The one source that reaches every room

Ductwork is the only part of a house connected to all of it, so growth inside the system does not stay put. The usual culprit is the cooling coil and the drain pan beneath it: the coil runs cold and wet all summer by design, and if the pan does not drain properly it sits as standing water inside a dark metal box with air blowing over it. The tell is a smell that appears within a minute of the system starting and fades when it stops, or growth showing at several supply registers at once rather than in one room. That pattern is worth testing for, because cleaning one room will not touch it.

Types of mold found in homes

What usually turns up, and what it indicates

A handful of genera account for most of what comes back from a house. Cladosporium is the most common and turns up on damp surfaces and in bathrooms. Penicillium and Aspergillus are the ones that dominate a sample when there is water damage somewhere, and Aspergillus in particular carries more weight for anyone with a compromised immune system. Stachybotrys, the black mold of the headlines, needs material that has been wet for a sustained period, so finding it usually means the water has been there a while rather than since last week. The species matters less than the count, but it does point at how long the problem has been running and how wet the material got.
