Our Medford, MA 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.
What sets our Mold Testing crew apart in Medford.
A contaminated duct system can spread spores throughout an entire Medford home via the HVAC system. This approach catches whole-house circulation issues a single-room test would miss.
