Our Holliston, MA technicians sample near supply and return vents specifically, which a standard single-room test would never catch.
Every result comes with a plain-language walkthrough connecting the data back to what you're actually experiencing at home. We'll also suggest a sensible next step, whether that's duct cleaning or a physician conversation.
Four reasons Holliston property owners trust us with this specific job.

This separation matters most when results factor into a bigger decision about your home. 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.
