When it comes to paying for air conditioning, maintenance tasks, like changing filters or paying someone to adjust the unit, make all the difference. Even something so simple as the temperature you have it set at can be key in determining how much it costs you.

Firstly, the ideal temperature for a bedroom is between 25 and 26 °C. This way, you’ll prevent a thermic shock when you move to a room with air conditioning to a room without.

Furthermore, the difference between the inside and outside temperatures should never be more than 5 °C (40 °F). To guarantee this, you can locate the thermostats both inside the bedroom and outside in direct sunlight. We also recommend that you also try to save energy. It’ll make your air conditioning less powerful, but it’ll also keep your bills down.

At what temperature should I set the air conditioning?

Air conditioners aren’t only the perfect appliance for cooling. They’re also very efficient in indoor temperature regulation. In some countries, with the suffocating heat of summer, it’s really tempting to have the air conditioning on maximum, 24 hours a day, every day.

However, it’s not exactly great for your health, nor your wallet, nor the environment.

If you’re still set on using it, you should try to be responsible. We recommend that you don’t set the air conditioning less than 78 F so as to maximize your home’s energy efficiency. Before you turn it on, we also recommend checking that all the doors and windows are firmly closed.

Most people reduce the air conditioning temperature instinctively to cool down as quickly as possible. However, this isn’t a wise idea. This just results in much greater energy consumption.

Using this appliance can make you much more comfortable. However, it can also be a huge additional cost if you’re not sensible. So, if you want to reduce your electricity bills, among other things, we recommend that you have programmable air conditioning that’s on less during the day when you’re not in.

  • During summer, if you’re one of those people who needs to air conditioning on in order to sleep, you can program it to be lower at night than during the day.
  • However, bear in mind that sleeping with the air conditioning on is not good for your health. So, if you can avoid it, try to not to have it on when you go to bed.
  • If you live in a mild climate, the air conditioning doesn’t need to be on all day. If it’s cooler in the evening, just open a window. You can turn it back on during the day if you need to.
  • If you have fans on the ceiling, then you can get away with the thermostat set up to 40 °F higher.

We also recommend trying to keep heat out of the house in the first place, whether it be coming in from outside, or produced by devices in your home, like dishwashers, tumble dryers, or washing machines. Make sure you use them at the coolest part of the day.
