The work
You will turn practical HVAC knowledge into examples that test how well AI models handle diagnosis, repair, and system design. You will also explain why solutions are correct and identify recommendations that are inefficient, technically wrong, or unsafe.
The work includes reviewing advice that could damage equipment or create serious hazards, such as compressor damage or carbon monoxide entering a home.
- Create realistic HVAC scenarios that move from symptoms to diagnosis and repair.
- Write reference answers explaining system behavior, charge selection, duct sizing, and sequence of operations.
- Evaluate AI responses for technical accuracy, efficiency, and safety.
- Identify plausible but unsafe or technically incorrect HVAC recommendations.
