Refrigerant log and AI field tools in Canada and the USA (CSA B52, EPA 608)

How to document refrigerant charges and recovery on both sides of the border: refrigerant log, CSA B52 and halocarbon rules in Canada, EPA Section 608 in the USA, plus HVAC-R AI assistant, P/T charts, nameplate scan and configurable °F/°C units.

A refrigerant log does not share the same legal basis in Canada and the USA, but the field logic is identical: document every charge and recovery, per unit, without paper getting lost in the truck. In Canada, the CSA B52 standard and the federal halocarbon regulations govern refrigerant handling. In the USA, Section 608 of the Clean Air Act, enforced by the EPA, requires technician certification and recordkeeping.

Why the log matters on both sides of the border

Whether for an inspection, proof of service or leak tracking, a company must be able to show how much refrigerant was added or recovered, on which unit and on what date. A digital log tied to the equipment replaces the crumpled notebook and makes data exportable in seconds.

CSA B52 and halocarbons in Canada

The CSA B52 mechanical refrigeration code and the federal halocarbon regulations frame recovery, handling and recordkeeping of refrigerants in Canada. FrigoTechPro logs charges and recovery per work order and per unit, then exports a log aligned with that logic.

EPA Section 608 in the USA

In the USA, Section 608 of the Clean Air Act requires technicians to be certified and companies to keep records on refrigerant handling. FrigoTechPro helps keep those records — quantities, equipment, dates — in a structured way. The app is a documentation tool: the contractor remains responsible for meeting the regulation in their state and federally.

Field AI structures the measurement, without replacing judgment

The HVAC-R AI assistant does not invent a diagnosis for the technician. It helps order symptoms, compare measurements and draft the report faster. On a walk-in R-404A or a R-410A heat pump, the value is the same: less time writing, more time repairing.

P/T charts, superheat and subcooling

Pressure-temperature charts cover 50+ refrigerants. Combined with superheat and subcooling, they let you compare saturation before touching the charge — an essential step before adding refrigerant, in Canada as in the USA.

AI nameplate scan

Nameplate scan reads model, serial number and equipment data from a photo, then attaches them to the file. No more manual retyping on the roof or in a dark mechanical room.

°F / °C units and imperial system

Technical tools show °F first, with °C as secondary, which suits the American market and Canadian field work alike. Food-safety (cold chain) measurements can stay in °C where the law requires it.

From log to report to quote to invoice

The refrigerant log does not live alone: it belongs to the same file as the report, quote and invoice. A charge documented on a work order flows into the service report, ready to be billed, in CAD or USD.
