Negative-pressure HEPA source removal, verified on camera and in a lab.

Source removal means the buildup is physically dislodged from the duct walls and pulled out of the system — not sprayed, masked, or blown around. Brushes and compressed-air whips agitate every supply and return run while a truck-mounted HEPA vacuum holds the whole system under negative pressure, so loosened debris travels toward the collection unit instead of into your rooms.

With the system under negative pressure, air moves in one direction only: from your registers toward our HEPA collection unit. That is what keeps decades of dust, dander, and fiber from escaping into the living space while we work. A portable vacuum held at a register cannot do this.

Yes, on every air duct cleaning. The air handler is where dust concentrates and where moisture meets the coil, so a job that skips it leaves the dirtiest part of the system untouched. We open the unit, clean the blower assembly, brush the coil surface, and close it back up the way we found it.

Two ways. First, HEPA-cam footage: we film inside the main trunk and individual registers before and after, and you review the dirtiest vents side by side. Second, the IAQ Lab Report: sealed air samples taken before and after go to an independent Maryland lab, and the report reaches you within 5 business days. Proof from a camera and a third party — not our word.

A blow-and-go crew blasts compressed air into a few registers with a portable vacuum, sprays a fragrance, and leaves in under an hour. What it skips: negative pressure across the system, agitation of the return side and trunk lines, the air handler and coil, any camera verification, and any independent measurement. Ask any vendor to show you before/after camera footage and an independent lab report.

No. Every Eagle air duct cleaning follows the same procedure. We price by job complexity — vent count, number of systems, add-ons — and quote in person, in writing, before any work starts.
