HVAC Systems Troubleshooting Essentials

Hands-on troubleshooting skills for CRAC/CRAH systems and common cooling failures.

4 hrs · self-paced online Cooling & Efficiency

Built for technicians who need practical troubleshooting skills, not design theory. This course covers refrigeration cycle fundamentals, psychrometrics basics, and hands-on CRAC/CRAH diagnostics — the skills you use during an actual cooling failure, not just a scheduled inspection.

You'll work through common failure modes, airflow measurement techniques, and a preventive maintenance schedule you can apply immediately, plus emergency troubleshooting procedures for when cooling capacity drops unexpectedly.

What You'll Learn

  • Diagnose common CRAC/CRAH failure modes quickly and accurately
  • Apply refrigeration cycle fundamentals to real troubleshooting scenarios
  • Measure airflow correctly to identify cooling distribution problems
  • Build a preventive maintenance schedule that reduces emergency callouts
