Air conditioning maintenance and installation tips for late summer

Homeowners can optimize energy costs and installation timing for air conditioning units as the summer season ends.

For those using air conditioners solely in the summer, disconnecting the power supply can prevent unnecessary standby consumption. While standby power is relatively low—estimated by Xataka Smart Home to be between 0.5 and 4 watts for units under 15 years old—it can result in annual costs ranging from approximately 0.38 to over 3 euros per device. If the unit is used as a heat pump during autumn or winter, keeping it in standby mode is recommended. To disconnect safely, users should unplug the device or use the dedicated circuit breaker in the electrical panel; if the unit is hardwired, professional assistance is advised.

Additionally, late August is identified as an advantageous time for new installations. During this period, demand for technicians typically decreases compared to the peak months of June and July, leading to shorter waiting lists and potentially more competitive pricing for labor. Installing a unit at this time also ensures availability of various models and readiness for heatwaves that may persist into September.
