HVACR Training Courses

I-know.com is an award-winning global online education platform offering eLearning courses and reference information material to the Heating, Air Conditioning, Refrigeration and BSE industries. It was developed by Star Refrigeration back in 2006 as an alternative learning tool to provide HVAC&R engineers with a quick, easy and convenient way to update knowledge, encourage good practises and share technical expertise.

The platform offers a set of resources focused at further professional careers and obtaining technical knowledge, and offers support for technicians through a free Library packed with hundreds of Health & Safety Bulletins, Risk Assessments, Method Statements, Handbooks and Papers, and inside ‘how-to’ guides from leading refrigeration and air conditioning organisations. All the material has been created from the extensive knowledge and expertise of professional engineers within the Heating, Air Conditioning, Refrigeration and Heat Pump industry.

Star Refrigeration's eLearning project has awarded thousands of CPD accredited diplomas to a variety of customers, including the world’s leading contractors, retail operators and end users and has prepared and certified thousands of technicians around Europe for F-Gas Certification. Its community continues to grow and it is currently 15,000 members strong.

Working in partnership with international organisations such as UNEP and The International Institute of Refrigeration, this platform aims to raise awareness of eLearning opportunities for the industry; up-skilling and re-skilling, aiding the exchange of experiences and sharing of knowledge and ideas within the industry worldwide and providing engineers with a rounded view of the operational concepts, procedures, safety measures and new environmentally friendly technologies that have already been successfully adopted by leading organisations worldwide.

Through a network of international business partners - with whom we co-produce relevant products for specific markets, co-operate to build mutually beneficial relationships, and establish licensing agreements worldwide - the user’s virtual learning experience is complemented with practical training and assessment for HVACR qualifications throughout a range of global locations at our partners centres.
