What Is SEER and Why Does It Matter?
SEER stands for Seasonal Energy Efficiency Ratio. It measures how much cooling energy (in BTU or kWh) a system produces for every unit of electrical energy consumed over a full cooling season. A SEER of 6.0 means the system delivers 6 units of cooling energy for every 1 unit of electricity. In the context of European electricity prices (averaging €0.28–0.35/kWh in 2026), this directly determines your running costs.
SEER Values Across AC Types
| AC type | Typical SEER | Annual cooling cost (8h/day, 90 days, €0.30/kWh) |
|---|---|---|
| Single-hose portable | 1.5 | €388 |
| Dual-hose portable | 2.2 | €265 |
| Portable split (PortaSplit Cool) | 6.1 | €95 |
| Portable split (PortaSplit HC) | 8.5 | €68 |
| Fixed mini-split (budget) | 6.5 | €89 |
| Fixed mini-split (premium) | 9.0 | €64 |
(Based on 9,000 BTU / 2.6 kW cooling capacity, 8 hours/day, 90-day season at €0.30/kWh.)
The Hidden Cost of Low-SEER Units
A single-hose portable AC appears cheaper at €250–400 purchase price versus €899 for the Midea PortaSplit Cool. However, over a typical 5-year ownership period in a city like Amsterdam with 3-month summers, the running cost difference is substantial:
- Single-hose: €388/year × 5 years = €1,940 in electricity
- PortaSplit Cool: €95/year × 5 years = €475 in electricity
- Total cost of ownership difference: €1,465 in electricity savings alone
The €649 price premium of the PortaSplit is recovered in electricity savings in approximately 2.5 years. From year 3 onwards, the PortaSplit user saves over €290/year compared to the single-hose owner.
R-290 Refrigerant: Efficiency and Environment
The Midea PortaSplit uses R-290 (propane) refrigerant, which offers thermodynamic properties that enable higher efficiency than the HFC refrigerants (R-32, R-410A) used in most competing products. R-290 has a Global Warming Potential of just 3 — compared to 675 for R-32 — making it the most environmentally responsible refrigerant choice available in consumer AC equipment today.
EU Energy Label Requirements 2026
Under EU Regulation 2016/2281 (Ecodesign), portable air conditioners sold in Europe must meet minimum energy performance requirements and carry the EU Energy Label. The Midea PortaSplit meets and exceeds current requirements. When purchasing any portable AC, verify the energy label is displayed and check that the SEER value is independently certified rather than manufacturer-claimed only.
Choosing the Right Model for Amsterdam
For coastal cities and areas with moderate winters, the PortaSplit Cool (SEER 6.1, €899) provides excellent summer cooling at the lowest price point. For cities further north or with significant winter heating loads, the PortaSplit Cooling & Heating (SEER 8.5, €1,199) provides year-round climate control at best-in-class efficiency.
