HVAC Troubleshooting & Diagnostic Tool
Pick a symptom and walk the same kind of guided decision tree PocketTech puts in your techs' hands. Cheapest, most-common causes first, always confirmed with your own readings. Built so your newest hire can diagnose like your best one, instead of reflex-swapping parts.
What’s the symptom?
For licensed pros. This is a field-triage aid, not a substitute for training, manufacturer specs, or your own meter and gauge readings. Follow lockout/tagout and all gas and electrical safety practices, and verify every diagnosis before you act.
Diagnostic skill shouldn’t live in one person’s head
The hardest part of growing a shop is that your best diagnostician can only be on one call at a time. Everyone else guesses, swaps parts, and calls the senior tech, or worse, the customer gets a callback. In a labor market where you’re lucky to hire at all, that bottleneck caps how much work you can take.
A guided decision tree flips that. Send a newer, lower-cost tech to the call, let the tree walk them to the right root cause, and you protect the margin you already earned:
- Fewer callbacks, every tech works the diagnosis the same, proven way.
- Bigger crews, sooner, a green tech is productive in weeks, not years.
- Right the first time, surface common, cheap causes before condemning a compressor.
- Straight to the estimate, in PocketTech, the diagnosis auto-builds the quote.

HVAC troubleshooting tool FAQ
Is this HVAC troubleshooting tool free?
Yes, completely free, no signup or email. Pick a symptom and walk the guided decision tree. It’s a working sample of the diagnostic system built into PocketTech.
Can a green tech really diagnose a call with this?
That’s the point. Instead of relying on years of gut feel, a newer tech answers plain questions in order and the tree surfaces the most likely cause, cheapest and most common failures first, always confirmed with instrument readings. It turns diagnostic skill that normally lives in a few senior heads into a repeatable process.
Is this a substitute for training or safety procedures?
No. It’s a field-triage aid for licensed professionals, not a replacement for proper training, manufacturer literature, or your own meter and gauge readings. Always follow lockout/tagout and gas and electrical safety practices, and verify every diagnosis before acting.
How is PocketTech’s built-in diagnostics different from this free tool?
This is one small taste. In PocketTech the trees are tailored to the equipment you service, every run is logged, the diagnosis auto-generates the estimate, and the system tracks each tech’s accuracy so the trees and your training get smarter over time.
Does it cover heat pumps and commercial equipment?
This free tool focuses on the most common residential and light-commercial split-system symptoms. PocketTech’s in-app diagnostics can be extended to the specific equipment, brands, and models your shop works on.
