During a heatwave, the air conditioner is non-negotiable. But running it without a strategy leads to high electricity bills and unnecessary environmental impact. Efficient use starts with choosing the right unit and extends to small daily habits that make a genuine difference.
The first rule is to invest in a quality air conditioner, preferably with inverter technology. Models from the OneClima range continuously adjust their output to actual demand: fewer on/off cycles, lower energy consumption and a longer lifespan.
The right temperature and energy savings
The recommended setting is around 26°C. Each degree below this threshold can increase consumption by up to 7%. Also avoid large temperature differences with the outside: excessive thermal shocks put unnecessary strain on the unit and can cause health problems.
Making the most of available features
Modern air conditioners include functions specifically designed to improve energy efficiency:
- The Eco mode reduces consumption without noticeably affecting comfort.
- The Dehumidify function is ideal on the most humid days: it removes excess moisture and improves the feeling of freshness without having to lower the temperature significantly.
- The programmable timer switches the unit on or off at chosen times, avoiding unnecessary running.
Ventilation and insulation: your energy-saving allies
Switching on the air conditioner is not enough on its own. The room must be able to hold the cool air. These measures help:
- Use blackout blinds or external shutters during the hottest hours of the day.
- Keep doors and windows closed while the unit is running.
- Ventilate only in the early morning or late evening when outdoor temperatures are lower.
Where possible, improve the thermal insulation of your home, particularly in attic rooms or south-facing spaces.
Maintenance: a matter of efficiency and health
A neglected air conditioner uses more energy and can become a breeding ground for bacteria, mould and allergens. Clean the filters at least once a month during periods of heavy use. A more thorough service at the end of the summer season preserves performance and prepares the unit for the months ahead.
Using your air conditioner efficiently during heatwaves does not require major effort. With the right model from the OneClima range, correct settings, a well-prepared room and regular maintenance, you reduce both consumption and costs while moving towards a more sustainable home.
