A portable air conditioner typically uses between 1 and 2.5 (sv) kr per hour, depending on the model, the price of electricity and how much the compressor is running. For the Wood’s AC Cortina 12K, this equates to approximately 2.43 (sv) kr per hour at full power, but the actual cost is often lower as the compressor does not run continuously.
When the summer heat sets in, many people want to cool down their bedroom, living room or home office. At the same time, the same question almost always crops up:
The short answer is: less than many people think, especially if you use it correctly.
Let’s take the Wood’s AC Cortina 12K as an example. It has a maximum power output of 1,350 W (1.35 kW) when the compressor is running at full capacity. If we assume an electricity price of 1.80 (sv) kr/kWh, the cost will be approximately:
| 1 hour (maximum power) | approx. 2.43 (sv) kr |
| 5 hours (maximum power) | approx. 12.15 (sv) kr |
| 5 hours (normal use) | approx. 8.50 (sv) kr |
| July–August (5 hours/day) | approx. 525 (sv) kr |
A portable air conditioner uses the most electricity when the compressor is working to cool the room. Once the desired temperature has been reached, the compressor does not need to work as hard. It then reduces its load or stops temporarily, whilst the fan continues to circulate the air. This means that a portable air conditioner rarely operates at maximum power throughout its entire running time.
In a normally insulated room, you can often expect the compressor to run for around 70% of the time, which means that the actual electricity cost is significantly lower than the maximum.
Wood’s AC Cortina 12K AirSwitch has been developed for summer nights. During the day, it functions as a powerful portable air conditioner. When the outside air becomes cooler than the air indoors, the patented AirSwitch™ technology can automatically switch from compressor cooling to using the cooler outside air to continue cooling the room. As the compressor switches off, only the quiet fan is used. The result is both lower energy consumption and a significantly lower noise level:
Over five hours of use, the AirSwitch mode therefore costs approximately 50 öre.

Start cooling before the room gets hot
If you wait until the room has become very hot, the air conditioner has to work much harder. Instead, start cooling an hour or so before you plan to use the room.
Keep doors and windows closed
If warm air is constantly coming in, the air conditioner has to work harder than necessary.
Keep the sun out
Blinds, curtains or awnings reduce heat gain and help keep the room cooler.
Cool the right rooms
It’s much more energy-efficient to cool the bedroom or living room where you spend your time than to try to cool the whole house.
The most common mistakes are:
For most households, the answer is no. A modern portable air conditioner often costs just a few kronor per evening to run. At the same time, you get a cooler home, a better night’s sleep and a significantly more comfortable indoor climate during the hottest days of the year.
With Wood’s AC Cortina AirSwitch, the cost can be even lower on cool summer nights thanks to the energy-efficient AirSwitch™ technology.
Wood’s AC Cortina 12K has a maximum power output of 1,350 W, which corresponds to approximately 2.43 (sv) kr per hour at an electricity price of 1.80 (sv) kr/kWh. As the compressor does not run continuously, the actual cost is often lower. With Wood’s AC Cortina AirSwitch, energy consumption can be reduced even further. In AirSwitch mode, only 56 W used, which equates to approximately 10 öre per hour.
For most households, therefore, enjoying a cool home during the summer costs less than many people think.
No. For most households, a portable air conditioner costs just a few kronor per hour, and the actual cost is often lower than the maximum.
It depends on the model and the temperature, but as the compressor does not run continuously, the cost is often significantly lower than many people think. With AirSwitch™, energy consumption can be reduced even further on cool nights.
Close doors and windows, use sun blinds, start cooling before the room gets hot, and choose an air conditioner suited to the size of the room.
Yes. A smaller, enclosed room requires significantly less energy than trying to cool several rooms at the same time.
A portable air conditioner typically uses between 1 and 2.5 (sv) kronor per hour, depending on the model, the price of electricity and how much the compressor is running.
When AirSwitch™ is in use, the compressor does not run. Power consumption is then only around 56 W, which corresponds to approximately 10 öre per hour at an electricity price of 1.80 (sv)kr/kWh.
Yes. Modern portable air conditioners are designed to provide high cooling capacity with low energy consumption. By using them correctly, electricity costs can be kept to a minimum.
