What you pay
It warns you days ahead, before stock spoils or refrigerant has to be recharged after a leak. We don't give a savings figure: it depends on your rooms and your stock.
How is this calculated?
149 (single price, every use) + 90 (indicative hardware, per cold room) = 239, once. No fees; updates included.

The problem
The breakdown warns weeks ahead. Nobody hears it.
A cold room loses gas slowly or its condenser gets dirty for weeks before it fails. By the time the temperature rises, the stock is at risk and recharging gas is expensive. In the US, since 1 January 2026 commercial refrigeration holding 15 lb or more of HFC must repair leaks above 20 % a year (EPA, AIM Act); in the EU, the F-gas Regulation requires regular leak checks.
How it works
Cold Room Sentinel sits outside the cold room, without touching the gas circuit. It analyses how the unit runs every day and alerts your phone when signs of failure appear.
Installed outside the unit, without opening the gas circuit.
The system continuously logs how the cold room is running.
If it detects abnormal behaviour, it alerts your phone with time to act.

FAQ
Do I have to open the refrigerant circuit to install Cold Room Sentinel?
No. It sits outside the cold room, without touching or opening the gas circuit.
What does my cold room need so I can monitor it?
An accessible condensing unit, an internet connection on site and a power outlet near the unit.
Will it help me meet the EPA leak-repair rule?
It gives you early alerts when signs of failure appear, with time to act, and a dashboard with all your rooms. It does not certify compliance with the EPA rule (AIM Act, in force since 1 January 2026) or the EU F-gas Regulation.
What does it cost in total?
One price: $149, one-off, for every use, with updates included. Hardware is bought separately, from about $90 per cold room.
When do I get my licence?
Within 12 hours of payment you receive your licence by email with a private link to the software and documentation. If it is late, you get your money back.
I am a refrigeration tech: can I install and monitor it for my clients?
Yes. The single price already covers installing it for your clients and charging them for the service yourself. The only thing it does not include is reselling the software on its own.
Can you install it for me?
Yes, optionally and as quoted: remotely anywhere or on site depending on your area, without opening the circuit.
Do updates cost extra?
No. Periodic software updates are included in the price, with no subscription or extra cost, and we let you know when a new version is out.
