Romanian households advised to set air‑conditioner between 24‑26 °C for comfort and efficiency

Energy experts recommend setting residential air‑conditioners in Romania to a temperature range of 24 °C to 26 °C during hot weather. This interval balances personal comfort with lower electricity consumption and reduces wear on the compressor. Temperatures set much lower, such as 18 °C, do not cool a room faster but cause the unit to run longer, increasing energy use and accelerating component ageing. A temperature difference of about 6–8 °C between outdoor and indoor conditions is sufficient for a noticeable cooling effect while avoiding thermal shock when moving between environments. Proper humidity control by the air‑conditioner also improves perceived comfort.

The residential market is seeing growing demand for air‑conditioners equipped with heating functions. Modern units use air‑to‑air heat‑pump technology, allowing the same device to cool in summer and provide efficient electric heating in winter, even at outdoor temperatures down to –20 °C or lower. This versatility reduces the need for separate heating systems, helps households cope with rising gas prices, and offers room‑by‑room temperature control, contributing to overall energy savings and year‑round thermal comfort.
