About Chiller Tech Support
Chiller Tech Support is an HVAC, refrigeration, electrical, plumbing, and welding training and technical-support platform serving technicians across the United States. We are not a textbook company — our content is built by working technicians for working technicians.
The platform includes free Diagnostic AI (no account required), live certified technician support billed by the minute, a searchable manufacturer fault-code database covering major HVAC and chiller brands, and self-paced training tracks on refrigeration theory, electrical controls, pipe fitting, welding fundamentals, airflow/psychrometrics, brazing, and trade certification prep.
We serve individual technicians, apprentices, journeymen, contractors, and supply house partners across all 50 US states. Whether you need a quick fault-code lookup at 2 AM or a structured path to your journeyman exam, we have tools for both.
