Summer is coming, and air conditioning is Spanish people’s best friend. After the first heat wave in Spain reached extreme temperatures up to 46ºC, the use of air conditioning has increased to the point of being almost indispensable. Even though the temperature has lowered in some parts of the country, the heat is still present and it’s expected to keep going for the next few months.

Everytime we experience hot temperatures, we tend to use fans or air conditioning to relieve this situation. However, we should know how to properly use them if we want to avoid paying more than we should. So, to make the most of these devices with no expensive electricity bills, we will show you some tips you can follow. Let’s get started!

What experts say about air conditioning

An expert from an air conditioning company has shared some recommendations on how to use air conditioning on social media. These tips could be so helpful to get rid of common myths and confirm some others. I’m sure everybody will benefit from these 5 things we should do when we want to feel the temperature at home colder when it’s hot outside. Let’s see what he has to say and if he will deny most of the things people have believed their whole lives!

1. The bigger, the better

The expert says it’s true a bigger air conditioning will cool a room much faster, but it could also have negative consequences. What he means is if the device has more power than it’s needed in the room it’s installed, it could generate unnecessary energy consumption. So, make sure your air conditioning is the right size for the room you want to use it in.

2. The lower the temperature, the faster it will cool

Adjusting your air conditioning up to 18ºC instead of 24ºC won’t make your room cool faster. Modern devices are prepared with technology and apps making them able to reach the desired temperature quickly and efficiently, with no need of adjusting it to very a low temperature.

3. The air removes smells

That’s totally the opposite! The expert also denies this false common knowledge. Air conditioning doesn’t get rid of smells, what it does is emphasize them, so the best thing to do is buying devices including special filters or purification systems.

4. Energy consumption changes with the temperature

Will you consume the same energy with your air conditioning adjusted at 22ºC than at 25ºC? The answer is no. This consumption depends on the outside temperature and the thermic difference between inside and outside. The bigger this difference is, the more energy you will be consuming.

5. Tuning it on or turning it off?

This is probably the most frequently asked question, some people turn the air conditioning off and on depending on whether they need it or not; whereas others decide to leave it on. What’s the best option? According to the expert, when we turn the device on is when most energy is consumed, so the most efficient way is to leave it on at a stable temperature as long as you need. Constantly turning it on and off would be the worst thing for its maintenance.

Now that you know how you should use the air conditioning, make sure you follow the expert’s advice to make the most of your device when hot temperatures reach your city. If you are one of those people who believed all those rumors about air conditioning, now you know the truth. Have a go at these recommendations and share it with your friends and family, I’m sure they will appreciate it!
