No, F-Gas certification is not required to install the Panasonic RAC Solo. Since the unit has no refrigerant connections, installers do not need an F-Gas qualification to carry out the installation. This makes the RAC Solo a more accessible and straightforward option compared to traditional split-system air conditioners.

Frequently asked questions
Does an installer need F-Gas to install Panasonic Rac Solo Air Conditioning?
Do all AC units have an outdoor unit?
No, they don’t. While most air conditioning systems require an outdoor unit, the Panasonic RAC Solo air conditioning unit is different. It only needs two 162mm wall openings for ventilation – no external condenser required. That’s one of the key benefits of this innovative product. If you don’t have outdoor space, or simply prefer an indoor-only solution, the Panasonic RAC Solo is an ideal alternative to traditional air conditioning.
How does air conditioning without an external unit work?
Unlike traditional split systems, air conditioning units without an outdoor unit house all the components in one indoor unit. They pull in air, cool it using internal components, and expel warm air through small ducts or grilles. Most require two small holes through an external wall for airflow, making them a compact and discreet solution.
Who is air conditioning without outdoor unit best for?
These systems are ideal for:
- Apartments and flats
- Listed buildings
- Conservation areas
- Offices and small shops
- Homes where installing a condenser isn’t possible
If you need discreet air conditioning with no outdoor unit, Panasonic Rac Solo is a great option.
Are air conditioning units without outdoor units effective?
Yes, air conditioning without an outdoor unit can be highly effective for cooling single rooms or small spaces. Modern models such as Panasonic Rac Solo are energy efficient, quiet, and powerful. While they may not cool large homes as effectively as split systems, they are perfect for bedrooms, home offices, or studios.
Is planning permission required for air conditioning without an outdoor unit?
In many cases, air conditioning without an external unit does not require planning permission because there's no external condenser box. However, always check with your local authority, especially for listed properties or flats in conservation areas.
