HVAC software in Canada and the USA: field AI, dispatch, CRM and multi-tax invoicing
Cross-border guide for HVAC-R contractors in Canada and the USA: one mobile app with AI assistant, nameplate scan, dispatch, schedule, time tracking, CRM, reports, quotes and invoicing with configurable taxes and currency (GST/HST/QST, sales tax, CAD/USD).
HVAC software in Canada and the USA has to serve two markets that look alike in the field but differ at the office. A technician does the same job in Montreal, Toronto, Calgary, Vancouver, New York, Houston or Miami: diagnose, measure, repair, document. What changes is billing: taxes, currency, language and professional numbers. Good software absorbs those differences without forcing the contractor to change how they work.
Same field work, two business models
A heat pump, a walk-in cooler or a rooftop is serviced the same way on both sides of the border. Pressures, superheat, subcooling and nameplate reading do not stop at customs. It is the administration — taxes, currency, language — that separates a Canadian company from an American one. Cross-border HVAC software must be strong in the field and flexible at the office.
Invoicing and taxes: the real friction point
In Canada, a company juggles GST, HST, QST in Quebec and PST in several provinces. In the USA, state and local sales tax varies from county to county. FrigoTechPro forces no tax model: the company configures its currency (CAD or USD), tax labels, rates, registration numbers and invoice messages for its market. The same app bills correctly in Quebec City, Ontario, Alberta, Texas or Florida.
Bilingual English and French
Canada is a bilingual market: in Quebec, a French invoice and report are not a luxury. FrigoTechPro runs fully in English and French — interface and documents. In the USA, English is enough, but the company keeps the French option for francophone technicians or customers, from New Brunswick to Louisiana.
HVAC-R AI assistant and nameplate scan
At the core of the app, the HVAC-R AI assistant helps structure symptoms, measurements and probable causes, then draft the service report. Nameplate scan reads model, serial number and equipment data from a photo. P/T charts cover 50+ refrigerants, with superheat and subcooling. These tools are identical in Canada and the USA: physics does not change at the border.
Dispatch, schedule and time tracking for teams
A two-tech company in Sherbrooke and a ten-tech team in Dallas share the same need: know who is where, which job is active, which customer to call back and which invoice still has to go out. Dispatch, schedule and employee clock-in connect field and office in real time, without triple entry.
From report to quote to invoice
A service report can become a quote, then an invoice, without re-entering parts, hours and photos. Everything stays tied to the customer and the equipment. The owner sees what to send, what is unpaid and what to follow up — in CAD or USD.
