Dedika is a platform where you learn by doing: whether it's creating a business proposal, becoming a manicurist, or learning to use a new tool, for example. No matter your goal, the best content on the subject already exists. But most times, it's in another language, expensive, scattered around, lacks practice activities, or comes in courses that are too long for people with busy schedules. That's why Dedika has its own method: we search for this material wherever it is, organise what makes sense for your goal, review it with the help of experts who are available to answer questions, and create practical exercises so you can learn by doing. You are the most important part of your journey and no one knows it better than you: choose the content and course duration, decide if you'll learn online or offline, and pick the format you prefer. It could be video, text, audio, or a summary. Your way, only with what makes sense for you. Here, every moment you dedicate counts for more, and you reach what matters faster.

Our courses include a summary at the end of each chapter, which you can download as a PDF and print.

Lesson 3 • Regulatory and Code Compliance Basics
Introduces mechanical, electrical, and refrigerant handling regulations governing HVAC work. Compliance awareness prevents violations and supports professional credibility.
Lesson 4 • Overview of HVAC Systems
Introduces heating, ventilation, and air conditioning as integrated systems. Connects system categories to real-world applications across residential and commercial settings.

Chapter 2See details

Thermodynamics and Heat Transfer Principles

Lesson 1 • Core Thermodynamic Laws
Explains the first and second laws of thermodynamics in HVAC context. These laws govern every energy conversion process in heating and cooling equipment.
Lesson 2 • Heat Load Estimation Basics
Applies thermodynamic principles to estimate building heating and cooling loads. Accurate load estimation directly determines correct equipment selection in later chapters.
Lesson 3 • Heat Transfer Modes
Covers conduction, convection, and radiation as the three mechanisms of heat movement. Understanding each mode explains equipment design choices and performance limits.
Lesson 4 • Refrigeration Cycle Fundamentals
Traces the vapour-compression cycle through evaporation, compression, condensation, and expansion. This cycle is the operating core of most cooling and heat pump equipment.
Lesson 5 • Psychrometrics and Moist Air Properties
Introduces humidity ratio, dew point, wet-bulb temperature, and the psychrometric chart. These properties drive load calculations and equipment sizing decisions.

Chapter 3See details

Refrigerants and Fluid Systems

Lesson 1 • Refrigerant Charging Procedures
Teaches superheat and subcooling methods for accurate system charging. Correct charge levels are essential for equipment efficiency and component longevity.
Lesson 2 • System Evacuation and Leak Testing
Details deep vacuum procedures and pressure testing to ensure system integrity before charging. These steps prevent contamination and premature compressor failure.
Lesson 3 • Refrigerant Handling and Recovery
Covers certified recovery procedures, cylinder management, and leak detection methods. Proper handling prevents environmental violations and protects technician health.
Lesson 4 • Refrigerant Classification and Properties
Categorises refrigerants by chemical family, global warming potential, and safety group. Classification knowledge guides compliant refrigerant selection and substitution decisions.
Lesson 5 • Hydronic and Fluid Piping Systems
Introduces water-based heating and cooling distribution, pipe sizing, and pump selection. Hydronic systems complement refrigerant-based equipment in many commercial installations.

Chapter 4See details

Heating Equipment: Types and Operation

Lesson 1 • Boiler Systems and Hydronic Heating
Covers hot water and steam boiler types, controls, and distribution components. Boilers serve large residential and commercial heating loads where forced-air systems are impractical.
Lesson 2 • Electric Heating Systems
Addresses resistance heating, heat strips, and electric boilers used in heating applications. Electric systems offer installation simplicity and precise zone control.
Lesson 3 • Heat Pump Heating Operation
Explains how heat pumps extract outdoor heat for indoor delivery using the refrigeration cycle. Reversing valve operation and defrost cycles distinguish heat pumps from cooling-only units.
Lesson 4 • Gas-Fired Furnace Systems
Covers burner operation, heat exchanger function, and venting requirements for gas furnaces. Furnaces represent the most common residential heating equipment in the field.
Lesson 5 • Oil-Fired Heating Equipment
Explains oil burner components, combustion analysis, and nozzle selection for oil-fired systems. Oil heating remains prevalent in regions without natural gas infrastructure.

Chapter 5See details

Cooling Equipment: Types and Operation
