10 prompts every HVAC tech should have saved on their phone.

A few of them:
1. Photo of a compressor / capacitor / contactor → manufacturer + model + voltage + sources.
2. Paste a Manual J → check assumptions, flag oversizing, does the equipment match the load.
3. Customer says "no cool today, fine yesterday" → 5-question diagnostic before you roll a truck.
7. Vendor call asking to verify wire info → 3 tells + the legit callback number to use.

All 10 work in free Claude / ChatGPT / Gemini. No subscription. No software.
