Don't guess.
Prove it.
Professair helps HVAC technicians and students troubleshoot systems safely and logically. Start with the symptom. Take the measurements. Build the theory. Verify the diagnosis.
Troubleshooting is a process,
not a parts list.
Professair is designed around the habits good technicians use in the field. It doesn't try to replace the technician or instructor. It helps you reason through the system.
Observe
Define what the equipment is actually doing before deciding what is wrong.
Measure
Use temperatures, pressures, voltage, current, airflow, sequence of operation, and manufacturer information.
Verify
Test the theory against the evidence. A diagnosis that merely sounds right isn't finished.
Don't just give the answer.
Teach the process.
Teaching Mode is built for learning. Instead of jumping straight to a diagnosis, Professair can slow the problem down, ask targeted questions, connect new concepts to what you already know, and guide you through the reasoning.
Start with what you know
New HVAC concepts are easier to understand when they are connected to systems, experiences, or ideas you already understand.
Work through the evidence
Professair can ask questions, check understanding, and guide you through the sequence instead of simply handing you the diagnosis.
Learn the why
The goal is not just to solve one unit. It is to understand the principle well enough to apply it to the next system.
Attach the unknown to something known.
Teaching Mode uses analogies, scaffolding, targeted questions, and frequent checks for understanding. The answer matters. Understanding how you got there matters more.
Professair is becoming a
ChatGPT plugin.
The delivery system is changing. The Professair philosophy isn't. Instead of being a standalone Custom GPT, Professair is moving into ChatGPT's plugin system.
The public plugin is not available yet. Once publication is complete, this site will link directly to the official Professair listing.
Install the Professair plugin in ChatGPT once it is publicly available.
Bring Professair into a ChatGPT conversation when you need HVAC troubleshooting support.
Describe the symptom and provide the measurements and observations you actually have.
Professair applies its HVAC troubleshooting framework to help determine what to check next and why.
Diagnoses are theories
until they're proven.
Know when to stop.
Professair is educational support. It cannot verify field conditions, equipment condition, technician competency, or safety practices. Follow manufacturer instructions, employer policies, local codes, and applicable safety procedures. When safety is uncertain, stop work and consult a qualified instructor, supervisor, or licensed professional.
Use it. Break it. Help improve it.
Professair gets better when technicians and students tell me what worked, what didn't, and what should change.
