MasterTech.ai

MasterTech is a field diagnostic assistant and workflow tool for professional HVAC technicians and contractors.

FOR TECHNICIANS

• Guided AI diagnostic: structured intake (unit, symptom, readings), then a step-by-step loop that tells you the single highest-value test to run next, interprets your readings against the equipment, and ranks likely faults with honest confidence.
• Precision calculators: superheat/subcooling with live P/T across 10 refrigerants (R-410A, R-32, R-454B, R-22, R-134a, R-290, and the common commercial blends with proper dew/bubble handling), static pressure, airflow, duct sizing, fan laws, electrical, combustion, EPA recovery and leak-rate.
• Work orders: every diagnostic saves to a structured record with a homeowner-ready summary you can defend to the customer.
• Career profile: your closed-call record, self-reported credentials, and an open-to-work listing contractors can find.

FOR CONTRACTORS

• Live feed of your team's diagnostics as they happen.
• Team management with invite codes, per-tech scorecards, and reports.
• Find techs: search open-to-work technicians by skill, cert, and location.

Built for the field: fast, one-handed, honest about what it knows. AI analysis requires a connection; readings and drafts are kept if you lose signal.
