Gordon is a diagnostic and installation tool that turns the HVAC line set verification process from a manual, experience-dependent procedure into a guided, sensor-verified workflow. Every install ends with a certified, timestamped record and a dramatically lower callback rate.
The HVAC industry averages ~77% first-time install success for split systems. Nearly 1 in 4 installs requires a return visit, usually for refrigerant leaks, improper charge, or vacuum failures at the line set connections.
At 100 installs per month, that's 20+ extra truck rolls. Hundreds of thousands in annual losses. Gordon targets a callback rate of ≤5% through enforced process discipline.

Gordon 1.0 is a diagnostic and installation tool that turns the HVAC line set verification process from a manual, experience-dependent procedure into a guided, sensor-verified workflow. By automating prescribed pressure holds, vacuum verification, and refrigerant charge validation, Gordon reduces installation failures and callbacks.
A step-by-step install workflow that improves consistency, reduces callbacks, and creates a permanent record of installation quality.
Attach Gordon to the HVAC ports and connect to the vacuum pump, nitrogen, and site power. Scan the equipment QR code using the mobile app to initiate the digital setup and guided workflow.
After installation, Gordon performs automated pressure and vacuum testing. Once complete, the app displays the exact calculated charge and monitors the final fill in real-time. Sensor-enforced, not eyeballed.
The system generates a digital certification report and stores the data in the cloud for warranty tracking. Every install ends with a timestamped PDF, the proof of quality for the contractor, owner, and OEM.
Move the sliders to match your operation. Industry defaults are pre-loaded and based on ACCA benchmarks.
