What this experiment can and cannot establish
This capture records what two AI systems told a homeowner on 2026-08-15. It does not establish the actual market price for a specific repair, installation, or replacement because equipment, scope, permits, efficiency, ductwork, and diagnosis were not held constant in the prompts.
