Gordon transforms HVAC line set commissioning from a manual, experience-driven process 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 — meaning nearly 1 in 4 installs requires a return visit due to refrigerant leaks, improper charge, or vacuum failures, often tied to line set connections.
At 100 installs per month, that's 20+ extra truck rolls — quietly compounding into hundreds of thousands in annual losses. Gordon targets a callback rate of ≤5% through enforced process discipline.

Gordon 1.0 is a connected diagnostic and installation tool that shifts installation from technician-dependent measurement to tool-enforced verification. By automating prescribed pressure holds, micron-level vacuum verification, and refrigerant charge validation, it dramatically 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 — proof of quality for the contractor, owner, and OEM.
Assumes ~$2,000/truck roll. Current rework at ~23% callback rate; with Gordon at ≤5%.
