## What is HVAC/R Red Seal Exam Prep?

HVAC/R Red Seal exam prep for the Refrigeration and Air Conditioning Mechanic trade, Ontario trade 313A, with 1,500+ bilingual practice questions, full 125-question mock exams and five interactive HVAC/R labs containing 40 scored cases. The download is free and includes 50 practice questions and a 25-question sample mock; one C$19.99 in-app purchase unlocks the full bank, full mocks and advanced experiences. Diagnose a system through pressures, temperatures, airflow and control sequence—not only isolated formulas. Earlier paid-download customers retain full access. No subscriptions, ads or account.

FULL ACCESS INCLUDES
• Unlock the complete bank of 1,500+ English and Canadian French questions
• Full 125-question mocks following the published major-work-area allocation

• Five interactive HVAC/R labs with 40 scored cases

READ THE WHOLE SYSTEM
Diagnose simulated refrigeration conditions, explore the pressure-enthalpy cycle, trace electrical ladder and sequence-of-operation faults, inspect commissioning evidence and manipulate psychrometric airside relationships. Each lab connects measurements, likely causes and the next useful verification.

UNDERSTAND THE MISTAKE
See your selected choice beside the correct answer, read option-specific reasoning, add a private note and revisit weak areas through targeted practice. English and Canadian French are included throughout.

PRIVATE, OFFLINE AND YOURS
No account, advertising, product analytics or study-data sync. Answers, bookmarks and progress stay on your device, and the full experience works offline after download.
