Choosing an air conditioner for your house or flat is not only a matter of comfort, but also of energy costs. In recent years, manufacturers pay special attention to the energy efficiency of their devices, trying to offer consumers the best solutions to reduce electricity costs. When choosing an air conditioner, it is important to consider not only its cooling capacity, but also its power consumption, which directly affects your energy bills.
The energy efficiency of air conditioners is measured in EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio). The higher these ratios are, the less energy the unit consumes to reach the desired temperature. Let’s take a look at the top 10 most economical air conditioners that will help you save on energy without compromising comfort.
