What the energy label really tells you
In the EU, air conditioning is labeled with:
-
efficiency classes (cooling/heating)
-
Estimated consumption (depending on type)
-
noise level
All of this is part of the energy labeling framework applicable to the product.
SEER (cooling) and SCOP (heating): what do they mean?
-
SEER measures seasonal efficiency in cooling.
-
SCOP measures seasonal efficiency in heating (reversible equipment).
This is described in the labeling regulations and is widely explained by industry entities/manufacturers as "seasonal efficiency".
How to use it in practice: between two models with the same power (BTU), you choose the one with higher SEER/SCOP – it tends to cost less to deliver the same comfort.
How to estimate costs in dollars (simple method)
DECO suggests:
Power (kW) × hours/day = kWh/day , then you multiply by the price per kWh.
Note: Actual consumption depends on usage, insulation, and the set temperature — use this calculation to compare scenarios, not as a "fixed" value.
Tips to reduce consumption without "suffering"
-
Moderate and stable temperature (avoids spikes)
-
blinds/curtains during the sunniest hours
-
Closed doors (don't accidentally air-condition the entire house)
-
Clean filters and basic maintenance.
FAQ
Is an A+++ always better?
If you compare equivalent devices (same type and power), usually yes. But also check SEER/SCOP and noise levels.
Does the notebook have a different label?
There are specific rules for types such as "single duct/double duct" in labeling, so it's important to compare within the same category.
