The EU energy label for air conditioners, read properly

Since Regulation 626/2011, every air conditioner sold in the EU carries an energy label built on seasonal metrics: SEER for cooling and SCOP for heating — the latter declared per climate zone, with the label’s little map of Europe split into warmer (Athens), average (Strasbourg) and colder (Helsinki) zones. Seasonal testing weighted toward part-load is what made inverter equipment’s real-world advantage visible; the old full-load EER/COP numbers flattered exactly the wrong machines.

The thresholds worth memorizing

Comparison traps

Three recur across Europe’s retail sites. A headline class quoted for cooling while heating is a class lower — demand both lines. A spec sheet quoting the SEER of the smallest capacity in the range while selling you the 5 kW version — efficiency varies with size; read the exact model’s fiche. And cross-market confusion: UK-market SEER figures post-Brexit follow retained rules that mirror the EU’s, but US SEER2 numbers are computed differently — never compare a SEER 7 European split to a SEER2 15 American system except through the underlying physics.

Frequently asked questions

Is the new A–G rescaled label coming to air conditioners?

The EU is rescaling product labels family by family (fridges, washers and displays are done); air conditioners still use the 626/2011 A+++ format at this guide’s writing. Compare SEER/SCOP numbers rather than letters and the transition will never mislead you.

What does the label say about portables?

Single and double-duct portables carry their own label variant with EER-based classes — systematically lower than splits. The honest comparison between a portable and a split is exactly this label gap: typically two full classes.

Does a higher class justify its price premium?

For cooling-only Mediterranean use, the SEER 7 → 8.5 jump saves tens of euros a season — do the arithmetic against the premium. For reversible units heating all winter, each SCOP tenth works thousands of hours and the premium usually pays; the label’s heating line deserves more attention than its cooling line in most of Europe.
