Certificate in HVAC Preventive Maintenance

The Certificate in HVAC Preventive Maintenance is designed to provide learners with practical knowledge and technical skills required to plan, inspect, service, maintain, and monitor heating, ventilation, and air-conditioning systems before failures occur. The program focuses on systematic preventive maintenance practices that improve equipment reliability, operating efficiency, safety, service life, indoor environmental conditions, and overall system performance.

Learners will develop an understanding of preventive maintenance requirements for common HVAC equipment, including split and packaged air-conditioning units, air-handling units, fan coil units, chillers, cooling towers, pumps, ventilation systems, refrigeration equipment, ductwork, electrical components, controls, and associated piping systems.

The course emphasizes inspection schedules, cleaning, lubrication, filter replacement, coil maintenance, electrical checks, refrigerant-system inspection, condensate drainage, airflow and temperature monitoring, vibration and noise observation, control-system checks, water-system maintenance, equipment condition assessment, maintenance documentation, and follow-up actions. Emphasis is placed on identifying early signs of deterioration and addressing issues before they develop into major breakdowns or costly repairs.
