Preventive Maintenance for HVAC Systems Training

Learning Outcomes

• Apply systematic inspection procedures to identify potential faults in HVAC components.
• Analyze system performance data to determine maintenance priorities and schedules.
• Evaluate the condition of filters, belts, coils, and refrigerant levels using appropriate tools.
• Implement preventive maintenance tasks such as cleaning, lubrication, and component replacement.
• Demonstrate compliance with health, safety, and environmental regulations during maintenance activities.
• Document maintenance records and report findings to management for continuous improvement.

Target Audience

This course is designed for HVAC technicians, maintenance supervisors, and facilities managers seeking to enhance their preventive maintenance skills in commercial and industrial settings.

Prerequisites

None — open enrollment. However, basic understanding of HVAC systems is beneficial.

Course Outline

Practicals

Overview

Hands-on practicals form an integral part of this course, allowing learners to apply theoretical knowledge to real HVAC equipment. Learners perform inspections, cleaning, electrical checks, refrigerant handling, and complete maintenance routines under supervision, building confidence and competence for the workplace.

Practical Activities

• Safety and Component Identification — Learners identify major HVAC components on training rigs and practice safety protocols including lockout/tagout. (3h)
• Inspection and Cleaning of Coils and Filters — Learners perform visual inspections and cleaning of evaporator and condenser coils, filters, and drains. (4h)
• Electrical Testing and Control Calibration — Learners use multimeters to test electrical components and calibrate thermostats and pressure switches. (4h)
• Refrigerant Charging and Performance Measurement — Learners connect manifold gauges, measure pressures and temperatures, and adjust refrigerant charge. (3h)
• Comprehensive Preventive Maintenance Simulation — Learners perform a full preventive maintenance routine on a simulated HVAC system from start to finish. (2h)

Summatives

Each delegate is assessed continuously throughout the course via daily exercises, scored practical assignments, and a final summative test at the end.

Practical Assignments — 30%

Practical assignments are observed and scored against a rubric during the practical sessions. Each delegate's practical mark is averaged into a single 100% score and contributes 30% to the final total.

Daily Exercises — 20%

Every training day ends with a multiple-choice exercise scored out of 100%. The scores from each daily exercise are averaged across the duration of the course to produce a Daily Average mark, which contributes 20% to the final total.

Final Test — 50%

On the last day a final summative test is written. It is a multiple-choice paper with multiple-answer questions: each question may have more than one correct option, and a single wrong selection on a question marks the entire question wrong — no partial credit. The final test is scored out of 100% and contributes 50% to the overall mark.

Final Total

Component	Out of	Weight
Practical Assignments (rubric-scored)	100%	30%
Daily Average (multiple choice)	100%	20%
Final Test (multi-answer multiple choice)	100%	50%
Final Total	—	100%

All marks are recorded on the AATICD LMS and visible to each learner under their account.

Certificate

How it works

• Certificates are auto-generated on the AATICD LMS as soon as the marks pass the 50% threshold.
• Each certificate is a branded PDF with the delegate's name, the course title, the unit standard ID, NQF level, credits, and the date of issue.
• You can download or print your certificate from your LMS dashboard at any time after issue — there's no reissue fee and no expiry date.
• If you scored under 50% you can sit the final test again at the next scheduled session at no extra cost.

Where to find it

Sign in to the LMS, open your dashboard, and your certificates appear under My Certificates. Each entry has a View / Download button and a print option.
