Frequently asked questions about air conditioners

How many BTU do I need for my room?

Use the manufacturer’s “recommended room size” on the unit as a guide: approx. 20 m² → 9,000 BTU class, approx. 30 m² → 12,000, up to approx. 50 m² → 18,000. For south-facing or attic rooms choose the next larger class — the climate finder does the choosing for you.

May I install a split air conditioner myself?

No. Units with fluorinated refrigerant (e.g. R32) must be installed by a certified specialist company in accordance with EU Regulation 2024/573. You can get the installation accessories for your installer from us.

Can an air conditioner also heat?

Yes — modern inverter units heat very efficiently. The SCOP value shows heating efficiency: a SCOP of 4.6 means 1 kWh of electricity becomes 4.6 kWh of heat.

How does delivery work?

Shipping within the EU is free from €100 order value — below that, the exact cost is shown at checkout (unfortunately we cannot deliver to islands). Items in stock usually arrive in approx. 4–6 business days; otherwise approx. 4–8 business days — for Bosch units currently approx. 8–11 business days. For split air conditioners and heat pumps containing F-gas, the delivery time counts from receipt of the certified-installer documents. Compact units ship as parcels; large units by freight carrier with advance phone notice. You receive tracking by e-mail.
