You just bought a new air conditioner and you're wondering how much of the installation you can handle yourself. Some of it, yes. But not all of it, and for a very specific legal reason. Charging the refrigerant and commissioning the unit are reserved for professionals holding an F-Gas certificate under EU Regulation 517/2014. This applies across the European Union, not just in individual countries. What you can do yourself is the wall preparation work.
Wall preparation: what you can do yourself
No special certification is required for: drilling the wall penetration for the refrigerant pipes and electrical cables, and fixing the brackets for the outdoor unit. These tasks carry no regulatory risk, as long as you work carefully to avoid structural or cosmetic issues.
Work that requires a certified technician
- Refrigerant charging: Only a technician with a valid F-Gas certificate can legally handle refrigerant. This is EU law, not a manufacturer recommendation.
- Refrigerant circuit connection and vacuum evacuation: Connecting the pipework and pulling a vacuum with a vacuum pump also falls under this requirement.
- Commissioning: The technician verifies that the unit operates correctly and safely before signing off on the installation.
These steps require specialist tools and trained knowledge that only a certified professional can provide.
Risks of DIY air conditioner installation
Going DIY can look like a money-saver on paper. The reality is different. Incorrect handling leads to refrigerant leaks, poor cooling performance, and higher energy bills. More seriously, you risk voiding the manufacturer warranty, which almost always requires certified installation. And anyone who handles refrigerant without an F-Gas certificate risks significant fines under EU F-Gas Regulation 517/2014.
What a certified technician actually gives you
A certified installer sets up your unit properly: maximum efficiency, full manufacturer warranty, and correct documentation. It costs more upfront, but the hidden costs of a DIY mistake, a voided warranty, or a regulatory fine add up fast. The certified route is the cheaper one over any meaningful time horizon.
