About the course:
Irrespective of the course duration shown below; the F-Gas category I course is the minimum legal FGas qualification required by all RAC operatives who carry out service, maintenance, installation, commissioning, refrigerant charging, recovery or leak checking on RACHP systems.
If you are not familiar with refrigeration science and principles, or function of components in the vapour compression system or Pressure Enthalpy (pH charts) we recommend you attend the 5to10 day course where greater knowledge and practical training will be provided.
Duration: (contact us for a self assessment form to identify the duration you require)
- Re-assessment only (1 day course – no training)
- Experienced technicians (3 day course)
- Inexperienced technicians working in the industry (5 day course provides more practical experience)
- Novices to refrigeration (10 day course)
The City and Guilds course does not have an expiry date, however you should retrain every 12 months to maintain competence and comply with any quality management system.
You will be provided with pre-course reading to aid your learning prior to arrival.
