Our Karthaus, PA technicians sample near supply and return vents specifically, which a standard single-room test would never catch.
This service exists for the allergy seasons that never quite make sense, when indoor symptoms feel worse than outdoor pollen counts would explain. We'll also suggest a sensible next step, whether that's duct cleaning or a physician conversation.
Four reasons Karthaus property owners trust us with this specific job.
We sample air near supply and return vents specifically, not just general room air. This approach catches whole-house circulation issues a single-room test would miss.
We don't process our own samples — an independent lab handles every Karthaus analysis, keeping results unbiased. You can verify the lab's accreditation directly if that matters to you.
Indoor versus outdoor comparison sampling helps determine if your home is actually contributing to allergy season. This context shapes which testing method we recommend.
Every result comes as a written report you can share with a physician, HVAC contractor, or insurer. We're glad to explain the numbers directly with you over the phone.
Every Karthaus job gets scoped to the specific problem, not a generic checklist.
This method catches contamination the ductwork itself may be spreading room to room.
Where sampling suggests contamination, we can assess accessible duct sections directly for visible growth.
This comparison is especially useful when allergy symptoms don't match typical seasonal patterns.
Environmental Relative Moldiness Index testing analyzes settled dust using DNA methods for a whole-property picture.
This pairs well with air sampling when there's both a visible spot and a broader circulation concern.
If results point toward duct contamination, we'll explain realistic next steps.
We keep this transparent enough to explain fully before you book.
