Over 80% of New Mexico homes use flex ducting. Standard negative air machines operate at 5–20× the pressure flex duct manufacturers allow. The damage is real, documented, and preventable.
Truck-mounted negative air machines — the industry standard for decades — were engineered for rigid sheet metal ductwork. They generate operating pressures of 5 to 20 inches of water column (IWC). Flex duct manufacturers specify a maximum operating pressure of 1 IWC.
The math is simple: standard equipment operates at 5–20× the pressure limit. The result is structural collapse of the inner liner, separation of the wire helix, compression of the insulation layer, and the creation of new pathways for moisture, mold, and debris infiltration.
This isn't marketing. It's documented in a peer-reviewed whitepaper published in R&R Magazine by RamAir's own researchers.

System is calibrated to ≤1 IWC before any duct contact. Pressure is monitored continuously throughout the job.
Patented agitation tools loosen debris without exceeding pressure limits. Debris is suspended — not pushed through the system.
Low-pressure extraction removes suspended debris. All material is captured — nothing is re-circulated into living spaces.
Post-clean ductoscope inspection verifies duct structural integrity. Any pre-existing damage is documented in the report.
New Mexico's climate creates unique HVAC challenges. Desert dust, monsoon humidity swings, wildfire smoke, and altitude all stress duct systems in ways that don't occur in other regions. Combine this with the fact that over 80% of NM homes use flex ducting, and the damage potential from standard cleaning methods is enormous.
VerifiClean is the only company in New Mexico operating an authorized RamAir system. Every job we complete protects your duct infrastructure while actually cleaning it — not damaging it further.
