Stop flipping through a 400‑page manual mid‑call.

Describe the symptom. Upload the OEM manual if you have it. BluePeak gives you a ranked list of likely causes, each one tied to the exact page it came from, plus the field tests to confirm or rule it out.

Why I built this

You’re on a call with a unit you haven’t seen before. The customer is waiting, and you’re scrolling a 400‑page PDF on your phone trying to find the one table that tells you what suction pressure should look like at 95°F ambient.

BluePeak started from that, not from a market study. The manuals already have the answers. The hard part is finding them fast, on‑site, under pressure.

You describe what you’re seeing: symptoms, readings, equipment behavior. BluePeak reads the manual and gives you a ranked list of likely causes, each tied to a specific page and section, with the field tests you need to confirm or rule it out.

It doesn’t replace your judgment — you still make the call. It just means you’re making it with the manual actually in front of you, even in a mechanical room with no signal and a cracked phone screen.

This is early. I’m building it carefully, and I’d rather ship something honest than something flashy. If you try it and something’s off, tell me directly — it goes to my inbox.

How it works

Describe the symptom

No manual on hand? Type in what you’re seeing — high superheat, ice on the line, unit short-cycling — and get a first read right away.

Or upload the manual

Drop in the OEM PDF and BluePeak indexes it so every finding cites the exact page and section it’s based on.

Get ranked causes + tests

Each hypothesis comes with a confidence label and the field test to confirm or rule it out — not just a guess.

Save the case

Everything stays on the case record. Come back to it later, or hand it to another tech without re-explaining the problem from scratch.

Example output · unit not cooling, high superheat

Low refrigerant charge

Manual p. 42, charging table

CONFIRMED

Restricted metering device

Manual p. 58, TXV troubleshooting

SUPPORTED

Dirty condenser coil

General knowledge, no manual citation

SPECULATIVE

Scope and limitations

Better to say this upfront than have you find out the hard way.

What it does well

Cross-references your symptom description against the OEM manual and surfaces the most likely causes fast.

Manual-backed citations

Every hypothesis links to a specific page and section. Without a manual, it falls back to general knowledge and says so.

The model can be wrong

It’s an LLM. Verify findings against the actual equipment before ordering parts.

Not for emergencies

Gas leaks, carbon monoxide, live electrical hazards — follow your safety protocols first, always.

Output depends on input

A vague symptom description gets a vague answer. Real readings make the analysis useful.

Manual format matters

Standard PDF manuals work best. Scanned images may index poorly and reduce citation accuracy.
