Upgrading from category 2 to A2
Upgrading from category 2 to A2
New A2 refrigeration certificate replaces Category II, KMO certificate
New EU legislation on working with refrigerants means that the KMO category II certificate will be replaced by the new A2 refrigeration certificate. In future, you will need the A2 certificate to work with refrigeration and heat pump systems up to 1 kg of flammable and 3 kg of non-flammable refrigerants.
If you already have a KMO certificate, you must upgrade to an A2 refrigeration certificate via the course here.
If you have not worked with refrigeration systems and refrigerants for a long time, we recommend that you take the full A2 certificate.

NOTE! The deadline for upgrading to an A2 certificate is 12.3.2029.
Target group:
The course is aimed at skilled workers and similar target groups who, in their jobs, need an A2 certificate for handling refrigeration systems and heat pump systems with a maximum of 3 kg of refrigerant.
Course content:
Based on an existing Category II refrigeration certificate, you will learn to handle flammable refrigerants and obtain an A2 certificate to handle refrigerants used in stationary refrigeration, air conditioning and heat pump equipment, with refrigerant charge up to 3 kg according to Regulation (EU) 2024/573, as well as Implementing Regulation (EU) 2024/2215.
The course concludes with the test for the statutory authorization required to work with flammable and non-flammable refrigerants (A2 refrigeration certificate) of up to 3 kg in the EU. In Denmark, the area is also regulated by the Danish Working Environment Authority's Executive Order on Occupational Health and Safety Education, which means that with the A2 certificate you are entitled to work legally with refrigeration systems and heat pumps in Denmark of up to 1 kg of group 1 refrigerant fillings and up to 3 kg of group 2 refrigerant fillings (and 3 kg regardless of refrigerant type in the rest of the EU).
Goal:

Economy
The vast majority of courses at Techcollege are AMU courses. AMU is an abbreviation for ArbejdsMarkedsUddannelse and is a competency-based adult education. You can participate in AMU courses under advantageous conditions because the Ministry of Education provides financial support. Read about your options below.
If you are employed or self-employed, and if you have education up to and including skilled level, the following applies:
The course price can be seen under the individual course. You or your employer must pay the low rate. You can obtain VEU compensation (wage loss compensation) of DKK 1,017 per day, equivalent to the full unemployment benefit rate (2026 rate). A maximum of VEU compensation can be obtained for 10 weeks of AMU courses within a 12-month period, and a maximum of VEU compensation can be obtained up to 3 times for the same AMU target within a 12-month period. If you are more than 60 km from your home to the school, you can get a subsidy for food and accommodation at a CVR-registered accommodation. You must book and pay for food and accommodation yourself. After the course, you can get a refund of up to DKK 600 per day for documented expenses. This is done via Skolernas Digitale BlanketFlow: www.sdbf.dk. In addition, a subsidy for your transport (regardless of the means of transport) of DKK 1.12 per km is provided after the first 24 km. This is applied for together with the VEU allowance.
If you are employed or self-employed, and have a short higher education or higher education, the following applies:
The course price can be seen under the individual course. You or your employer must pay the high rate. There is no subsidy from the Ministry of Education, therefore the full course price is charged. There is no possibility of VEU compensation (wage loss compensation), and accommodation, meals and transport are at your own expense.
If you have not used your higher education within the past 5 years, it is considered obsolete, and you can therefore apply for a subsidy for food and accommodation as well as VEU compensation (see the instructions above under "education up to and including skilled level"). However, you must still pay the full course price.
If you are unemployed and entitled to 6 weeks of job-oriented training, the following applies:
As an unemployed person with the right to 6 weeks of job-oriented training, you can participate in AMU courses free of charge. When registering, you must provide TECHCOLLEGE with contact information for the unemployment insurance fund that will grant you the desired courses. If you are more than 60 km from your home to the school, you are entitled to a subsidy for food and accommodation at a CVR-registered accommodation. You must book and pay for food and accommodation yourself. After the course, you can be reimbursed up to DKK 600 per day for documented expenses. This is done via Skolernas Digitale BlanketFlow: www.sdbf.dk . You can also apply for a subsidy for your transport (regardless of means of transport) of DKK 1.12 per km after the first 24 km. This is applied for on form AB421, which must be submitted to your unemployment insurance fund.
If you are unemployed and are taking training as part of a job plan, the following applies:
As an unemployed person who wants to participate in training as part of a job plan, you can participate in AMU courses free of charge. When registering, you must provide TECHCOLLEGE with the contact information of your job center caseworker, who will grant you the desired courses. If you are more than 60 km from your home to the school, you must make an agreement with your Job Center before the course starts to grant and pay for your expenses for food and accommodation. You can also apply for a subsidy for your transport (regardless of the means of transport) of DKK 1.12 per km after the first 24 km. This is applied for on form AB421, which must be submitted to your unemployment insurance fund. You will find a link to the form here: https://info.jobnet.dk/blanketter
Financing via Competence Development Funds
The competence funds are an initiative in most collective agreements that may mean that your employer has already indirectly paid for the course! You can apply for a subsidy for continuing education via competence funds. The funds are a result of the collective agreement renewal and provide the opportunity to apply for a subsidy for self-selected continuing education and training. You can spend up to two weeks a year on self-selected education, and you can apply to the competence funds for a subsidy for course fees, salary reimbursement and accommodation. Ask about the options at your workplace.
