Indoor Air Quality, UV & Mold — Westford, MA

Sanitize is an add-on, not in the basic price. For active mold inside the ductwork we can do mold treatment as part of the job. Whole-home mold remediation (walls, ceilings, attic) needs a dedicated remediation company — we'll tell you which you actually need.

Yes — in-duct UV lights mounted in the air handler kill mold, bacteria, and airborne contaminants before they recirculate. It's one of our most popular IAQ add-ons, especially in dust-heavy climates and homes with pets or asthma, and pairs well with sanitize and a high-MERV filter.

We don't run lab air-quality testing in-house. During inspection we flag visible mold, excessive dust loading, and airflow issues; for lab-grade allergen, VOC, or mold-spore readings we refer to a partnered IAQ tester.

Yes. A musty smell usually traces to debris on a damp evaporator coil; an animal smell usually traces to a rodent intrusion in crawlspace or mobile-home ductwork. We inspect both, remove nest material, clean the runs, and sanitize the coil.

It helps most when paired with sanitize and a fresh high-MERV filter — that combination removes the dust, dander, and debris the system recirculates. Many Westford allergy households report noticeable relief within a few days.
