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 split system installation project, from equipment selection through operational verification, applying the professional techniques and procedures used in the industry.
The project includes selecting the right equipment based on the characteristics of the space being conditioned, planning the refrigerant line route to minimize length and pressure drop, defining mounting points for the indoor and outdoor units that meet minimum clearances, designing the electrical wiring diagram with proper protective devices, and providing a detailed description of the startup procedure with verification of operating pressures and temperatures.
The project also includes preparing an installation technical data sheet with equipment data, refrigerant used, line length, and verified operating parameters. You’ll document the recommended preventive maintenance procedure and the periodic checks needed to keep the system running correctly. The final documentation must meet the technical depth and professional format expected of work orders and installation certificates, demonstrating your ability to execute and document split system installations completely and rigorously.
ICTESS’s Course in Split Air Conditioning Systems includes hands-on training with the industry’s standard professional tools: digital manifold gauges for measuring high- and low-side pressures, a vacuum pump for removing moisture and air from the circuit, an electronic leak detector for tightness verification, a professional flaring tool for refrigerant connections on copper tubing, and a clamp meter for verifying electrical power draw. You’ll learn to use this equipment following the correct technical procedures, from circuit preparation through final operational verification. Mastering these tools is a baseline requirement to work at professional HVAC contracting companies.
Prior HVAC experience isn’t required, though basic electrical knowledge and some familiarity with hands-on technical work is recommended. The course follows a progressive structure that starts from split equipment fundamentals and builds toward advanced installation and startup techniques. People with backgrounds in electrical work, plumbing, industrial maintenance, or electromechanics will find the content accessible and complementary to their existing skills. It’s also suitable for people without prior technical training but with hands-on aptitude and motivation to learn a trade with strong job demand.
The ICTESS professional certificate validates your technical training in split system installation and is valued by industry employers as proof of specific skills. However, performing professional installations that involve handling regulated refrigerants requires EPA Section 608 Technician Certification, issued after passing a certification exam through an approved provider. The course gives you the technical knowledge you need for installation work, but the official refrigerant-handling certification must be obtained separately. Many contracting companies particularly value hands-on technical training like this as a complement to that certification, since it demonstrates real installation skills.
This Course in Split Air Conditioning Systems stands out for its hands-on, specific focus on the installation techniques industry professionals actually use. While many courses offer general theoretical content about HVAC, this program focuses on real working procedures: professional flaring techniques, correctly pulling a vacuum with proper timing and pressure targets, charging refrigerant while verifying superheat and subcooling, and wiring per manufacturer diagrams. The content covers today’s R-32 and R-410A refrigerants and their specific handling considerations, and covers the different split equipment types (wall-mounted, ducted, cassette, multi-split) you’ll encounter on real installations.
