Overview
- home&smart's consolidated guidance published on May 21–22 recommends monoblock units for renters and single‑room cooling and permanent split systems for owners seeking quieter, more efficient long‑term cooling.
- The De'Longhi Pinguino PAC EL112 CST is named testsieger for strong 11,000 BTU performance while the Midea Silent Cool Pro 26 WF is singled out as the quietest option and the Klarstein Kraftwerk Smart 10K wins on price‑performance despite higher noise levels.
- Midea's PortaSplit mobile split series is highlighted as a DIY alternative that places the compressor outside the living space for lower indoor noise and better efficiency without a permanent wall penetration.
- home&smart provides BTU sizing guidance to avoid under‑ or oversizing: 10–15 m² → 5,000–7,000 BTU, 20–25 m² → 7,000–10,000 BTU, 30–40 m² → 10,000–14,000 BTU and above 50 m² → from 18,000 BTU, and warns that wrong sizing raises running costs and reduces comfort.
- The update notes an early 2026 heatwave has created stock pressure on popular models and quantifies typical summer running costs as roughly €90–195 per room for monoblocks versus about €45–105 for efficient split systems, affecting purchase timing and household energy bills.
