Questions people ask
How much does a air conditioner cost to run per year?
On the EU register, the typical model in the most common group (split air conditioners, 6 kW and over) uses 402 kWh a year for one cooling season (heating is shown separately for units that also heat). At 0.283 €/kWh that is about €114 a year.
What do SEER and SCOP mean?
Seasonal efficiency: how much cooling (SEER) or heating (SCOP) you get per unit of electricity over a whole season. Higher is better; SCOP is given for three European climate zones.
Are portable air conditioners less efficient?
Yes. They push warm air out through a hose and pull warm air back in through gaps, and their label is based on hourly use rather than a season. Our yearly figure assumes 350 hours of cooling.
