Free Engineering Fundamentals Training for the HVAC Industry
Why the MEP Engineering Co YouTube Library Is So Valuable
The MEP Engineering Co YouTube channel offers more than 30 hours of free training across 32 long-form videos, made openly available to engineers and contractors across the HVAC and building services industry.
Rather than focusing on products or brand-led instruction, this library is valuable because it reinforces core engineering fundamentals—the knowledge that underpins safe, efficient, compliant, and buildable HVAC systems.
Core Engineering Topics and Why Each One Matters
DX Air Conditioning Systems
Understanding DX systems is essential because they remain widely used across commercial, retail, and retrofit projects. Misapplication or misunderstanding leads to poor efficiency, comfort complaints, and shortened plant life. Revisiting DX fundamentals helps professionals recognise where these systems work well—and where they don’t.
Cooling Towers, Fluid Coolers & Heat Rejection
Heat rejection is often treated as secondary to cooling generation, yet it directly governs system efficiency, reliability, water risk, and compliance. A strong grasp of these fundamentals is critical to managing energy performance, Legionella risk, and long-term operational cost.
Chiller Selection Fundamentals
Chillers are among the most expensive and critical assets in a building. Understanding selection fundamentals is essential to avoid oversizing, poor part-load performance, and mismatched redundancy strategies.
Water Chillers and Control Fundamentals
A chiller’s real-world performance depends on how it is controlled, staged, and integrated. Without understanding these fundamentals, even high-efficiency plant can perform poorly.
Water Boilers and Heating Systems
Heating systems are often simpler in concept but easy to misapply. Understanding boiler fundamentals is essential for safety, efficiency, and integration with air and water systems.
Ductwork and Pipework Insulation
Insulation is frequently underestimated, yet it directly affects energy use, condensation risk, comfort, and compliance. Understanding why thickness, continuity, and detailing matter is critical.
Application and Selection of Air System Equipment
Choosing the right type of air system has long-term implications for capital cost, energy use, maintenance, and flexibility.
Water-Based Air Conditioning Systems
Water-based systems underpin many large and complex buildings. Understanding their fundamentals is critical to designing systems that are scalable, resilient, and maintainable.
Fans
Understanding fan fundamentals helps reduce energy waste, noise complaints, and late-stage redesigns.
Heat Loads
Heat load calculation is the foundation of all HVAC design. Errors made here propagate through every system decision.
Psychrometric Chart
Psychrometrics sits at the heart of comfort, humidity control, and outside air treatment. Misunderstanding leads to mould risk, discomfort, and excessive energy use.
Fire Safety and Fire Matrix Fundamentals
HVAC systems are deeply integrated with fire and life safety systems. Understanding fire matrix fundamentals is essential to ensure systems behave correctly during fire events for compliance with As1668.1 and As1851
Control Systems
Controls determine whether a system delivers on its design intent. Without strong fundamentals, even well-designed systems underperform.
Final Takeaway
The MEP Engineering Co free training library is a rare industry resource: long-form, engineering-focused, and openly accessible.
For engineers and contractors who want to strengthen fundamentals, reduce project risk, and deepen their understanding of how HVAC systems truly work, these videos are well worth the time to watch. MEP Engineering Co. – YouTube
