Gordon — Thalo Labs
Day 1: Installation
Make Every Installer a Rockstar
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.
A Six-Figure Problem Hiding in Plain Sight
~1 in 4 Installs Requires a Return Visit
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.
- ~23% Industry install callback rate
- ≤5% Gordon target callback rate
- 20+ Extra truck rolls/mo at 100 installs
- $432K Annual savings at 100 installs/mo
The Solution
Quality Assurance, Not Just Measurement
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.
- Sensor-enforced vacuum holds. Won't pass until spec is met
- Continuous logged data that flags micro-drops automatically
- 4G LTE cellular. Leave on-site, get alerts remotely
- Auto-generated PDF certification with timestamped sensor data
- Real-time dashboard across all crews. Supervisors see bypass flags
- No more manual logs, paper sign-offs, or spreadsheet exports
Without Gordon vs. With Gordon
| Without Gordon | With Gordon ✓ |
|---|---|
| Tech eyeballs 5-10 min vacuum hold | Sensor-enforced full hold |
| Quick glance at gauge. Slow leaks undetected | Continuous data; flags micro-drops automatically |
| Tech must stay nearby or skip overnight tests | Cellular. Leave on-site, get alerts remotely |
| ~23% of installs require return visits | Target ≤5% with enforced process discipline |
| ~$552,000 in preventable rework at 100/mo | ✓ ~120,000, saving ~$432,000/year |
How It Works
Install It Right the First Time. With Proof.
A step-by-step install workflow that improves consistency, reduces callbacks, and creates a permanent record of installation quality.
Install
- 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.
Verify
- 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.
Certify
- 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.
