The Service Manager
Want your whole team making fewer callbacks? Print the checklists, share the prompt library, and stop getting the 'it wasn't working when I left' calls.
What Techs Say
“I used the no-cool flowchart on a call I'd been to twice before. Found a stuck TXV in 20 minutes. I'd been chasing low refrigerant for two weeks.”
Derek M.
Residential Service Tech, 9 years
“The ChatGPT prompts actually work. I described a compressor that kept tripping on high pressure and it walked me through 6 possible causes I hadn't considered.”
Anthony R.
HVAC Technician, Orlando FL
“I gave these to my 3 junior techs. Callbacks dropped 40% in the first month. It's just better structure for how to think through a call.”
Luis V.
Service Manager, DFW
