Why we built this

If you've worked in the field, you know the feeling: you're on a call with a unit you haven't seen before, the customer is waiting, and you're cross-referencing 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. Meanwhile the dispatcher wants an ETA on the part.

BluePeak started from that frustration. Not from a startup looking for a market — from someone who has been in that situation and wanted a better tool. The idea is simple: your OEM manuals have the answers. The hard part is getting to them fast, on-site, under pressure.

What we built is a diagnostic assistant that reads the manual for you. You describe what you're seeing — symptoms, readings, equipment behavior — and it gives you a ranked list of root causes, each one tied to a specific page and section in the manual, with the exact field tests you need to confirm or rule it out.

This is not a replacement for your judgment. You still have to make the call. But it means you're making that call with the manual actually in your hands — even when you're standing in a mechanical room with no signal and a wet phone screen.

We're a small team. We're building this carefully and incrementally, and we'd rather ship something honest than something flashy. If you try it and it doesn't work the way you expected, tell us. The goal is a tool that earns your trust one diagnosis at a time.

Everything you need on a service call

🔍 OEM-backed analysis

Upload the service manual once. Every hypothesis links to the exact page, section, and reference value from the manufacturer.

📊 Confidence levels

Each hypothesis is rated CONFIRMED, SUPPORTED, POSSIBLE, or SPECULATIVE — so you know how solid the diagnosis is before you pull a part.

🛠 Step-by-step field tests

Not just "what to test" — exact steps, required tools, and pass/fail reference values straight from the manual.

📌 Missing data flags

BluePeak tells you which readings it needs to raise confidence, so you know what to measure before you leave the unit.

📁 Persistent case records

Every case is saved with the full analysis. Come back later or hand off to another tech without losing context.

✅ Resolve or escalate

Close a case as resolved or unresolved when the job is done. Keep your service history clean and auditable.

How it works

Three steps from the service call to a clear answer.

Start a case

Enter the equipment brand, model, and what you're observing — high suction, low delta-T, locked compressor, whatever the complaint is.

Upload the service manual

Drop in the OEM PDF. BluePeak indexes it and uses it to back every finding with a manual citation. Skip this step if you don't have it — the analysis still works.

Get ranked hypotheses + tests

BluePeak returns a prioritized list of root causes, the evidence level for each, and the exact field tests to confirm or rule them out.

Resolve and document

Mark the case resolved. The full analysis is saved to your case history for review, handoff, or callbacks.

Scope and limitations

We'd rather be upfront about what this tool does and doesn't do than oversell it.

✅ What BluePeak does well

Cross-references your symptom description against the OEM manual and surfaces the most likely root causes — fast. Works best when you give it clear, specific symptoms and readings.

✅ Manual-backed citations

Every hypothesis links to a specific page and section in the uploaded service manual. If no manual is uploaded, BluePeak uses general HVAC knowledge and marks findings accordingly.

⚠️ AI can be wrong

BluePeak uses a large language model. It can make mistakes, miss context, or produce plausible-sounding output that doesn't match your specific unit. Always verify findings against the actual equipment before ordering parts or making recommendations.

⚠️ Not for emergencies

Do not use this tool as a primary guide for situations involving active gas leaks, carbon monoxide, live electrical hazards, or any condition that puts people at immediate risk. Follow your safety protocols first.

⚠️ Output quality depends on input

Vague symptom descriptions produce vague results. The more specific you are — actual readings, observed behavior, ambient conditions — the more useful the analysis will be.

⚠️ Manual format matters

BluePeak works best with OEM service manuals in standard PDF format. Scanned images, handwritten notes, or heavily formatted catalogs may not index correctly and may reduce citation accuracy.
