Best AI for troubleshooting, by trade

The short answer

Troubleshooting AI is uneven across the trades. HVAC has several tools, appliance repair has one good one, and for electrical and plumbing we found almost nothing a vendor will put in writing.

  • Kenner: Answers from the history of the unit: what fixed this fault before, its alarms, its parts and its manual. Our product.
  • Bluon MasterMechanic: MasterMechanic gives diagnostic and troubleshooting help, trained on more than 130,000 real technician support calls.
  • FixBot Pro: Looks up service documentation by model or fault code and builds a test sequence from the service manual.
  • HVAC/R AI Pro: An AI chat for troubleshooting from symptoms, measured readings, fault codes and job photos.
  • MyPros+: Max gives the most likely cause, the diagnostic steps and the expected test values from the service manual, and cites the page.
  • ServiceTitan Atlas: Atlas helps diagnose and troubleshoot, with diagnostic tests and calculators, and looks things up in equipment manuals.
  • ChatGPT: A general assistant with voice and photo input that can search the web and read an uploaded PDF manual. OpenAI advises verifying technical information.

HVAC and refrigeration

This is where the tools are. Bluon and FixBot Pro answer from manuals and model data. HVAC/R AI Pro works from what the technician types in. Atlas answers inside ServiceTitan. Kenner answers from the history of the unit: what fixed this fault here before.

Appliance repair

MyPros+ holds service documents for more than 100 brands and its assistant gives the likely cause, the test steps and the part number, citing the manual page. It says its guidance is for reference and should be verified against the manufacturer's documentation.

Electrical and plumbing

Kopperfield's NEC chatbot answers code questions for electricians. It does not diagnose faults. For plumbing we found no vendor that documents AI troubleshooting on its own pages.

That leaves a general chatbot. ChatGPT can read a manual you upload and take a photo, and OpenAI advises verifying technical information.
