Frequently Asked Questions
How do I choose the right BTU size for my room?
The key figure is the manufacturer’s recommended room size for this unit — you will find it in the product’s technical data. For sun-facing or top-floor rooms, we recommend the next larger capacity class. Our team is happy to advise.
Do I need a certified technician for installation?
Yes — split air conditioners with fluorinated refrigerant must be installed by a certified F-Gas technician (EU Regulation 517/2014). Self-installation is not permitted. We can arrange a qualified installer in your region.
What warranty is included?
Standard manufacturer warranty is 36 months on the unit, provided installation is carried out by a certified F-Gas technician. Detailed warranty conditions are in the product datasheet.
What do SEER and SCOP mean?
SEER (Seasonal Energy Efficiency Ratio) is the seasonal cooling efficiency — higher is better. SCOP (Seasonal Coefficient of Performance) is the seasonal heating efficiency. SEER ≥ 6.0 and SCOP ≥ 4.0 are considered very good for residential split air conditioners.
