The use of air conditioning has become increasingly common in Portugal, especially during the summer months. However, one of the most frequent questions is simple: what is the best temperature to use AC at home?
The right answer can make a difference not only in comfort, but also in energy consumption and the durability of the equipment.
The ideal air conditioning temperature
Generally, the most recommended temperature for using air conditioning at home is between 24ºC and 26ºC in the summer.
This range ensures a good balance between thermal comfort and energy efficiency.
Setting the AC to very low temperatures (such as 18ºC or 20ºC) may seem more comfortable at first glance, but in practice:
- significantly increases energy consumption
- puts more strain on the equipment
- can cause thermal discomfort when going from indoor to outdoor environments
The impact on the energy bill
For every degree below 24ºC, air conditioning consumption can increase significantly.
This means that keeping the AC at very low temperatures is not only unnecessary in many cases, but can also result in a higher electricity bill at the end of the month.
Tips for making better use of your home air conditioner
To get the most out of your air conditioner, consider these best practices:
- Maintain the temperature between 24ºC and 26ºC
- Avoid sudden temperature changes
- Close doors and windows when the AC is on
- Perform regular maintenance on the equipment
- Use the “eco” mode whenever possible
These small actions help improve the efficiency of the AC and reduce energy consumption.
Using your air conditioner intelligently makes all the difference, both in daily comfort and in your energy bill.
