Program details
The Capstone Project is the culminating stage of the program and represents the practical integration of every technical skill developed throughout the course. It consists of developing a complete preventive maintenance plan for a real or simulated HVAC installation, from the initial equipment assessment through scheduling periodic service calls, applying the professional methodologies and technical protocols used in the industry.
The project must include a technical inventory of the selected installation’s equipment (brand, model, capacity, location), defined maintenance tasks for each component, service intervals set according to usage and environmental conditions, and service record templates listing the parameters to verify and their reference values. You’ll also design an annual maintenance calendar and estimate the resources required.
The project includes simulating a complete, documented maintenance service call: visual inspection, component cleaning, electrical checks, operating parameter measurements, and an incident log. The final documentation must meet the technical depth and professional format expected of the work orders and maintenance records used by industry companies, demonstrating your ability to plan, execute, and document HVAC maintenance services in a rigorous, systematic way.
ICTESS’s Course in Air Conditioning Maintenance includes hands-on training with the industry’s standard technical instrumentation: a digital multimeter for measuring voltage, resistance, and continuity in electrical components; a clamp meter for checking compressor and fan power draw without interrupting the circuit; contact and infrared thermometers for checking supply and return temperatures; and refrigeration gauges for basic pressure readings on the refrigerant circuit. You’ll learn to interpret the readings you obtain and compare them against reference values to assess equipment condition. While the course focuses on maintenance rather than refrigerant handling, you’ll learn the verification procedures that let you identify when a call for an EPA Section 608 certified technician is needed.
