What is the consumption of an inverter air conditioner?

Air conditioners are one of the most used appliances in the summer, as they can keep rooms at a comfortable temperature. However, it is necessary to consider the electrical consumption of some models, which can become excessive, if they are not considered or calculated before buying them.


An air conditioner is designed for cooling a space, environment, room, etc. To function, they make use of a fan and a compressor, which are classified as the main components of the equipment. In this case, the fan is in charge of the output power and the compressor focuses on controlling the temperature. 

How does an air conditioner compressor work?

The air conditioners, when turned on and, depending on the selected temperature, will activate the compressor to the maximum, to quickly cool the air in the room.

Once the equipment sensors detect that the desired temperature has been reached, the compressor turns off. When the surrounding temperature rises again, this component turns on again. 

This action has a strong impact on the electrical consumption of air conditioning, so there are not a few brands that have tried to combat this excess, in order to offer equipment that does not constitute too important an expense.

Inverter air conditioner: what is it?

Inverter air conditioners could be the kind of equipment you are looking for to reduce electricity consumption at home.

The models that use this technology, unlike a normal air conditioner, keep the compressor activated, but vary its power, thus avoiding the on-off cycle.

Another advantage is that, aesthetically, there is no difference between a conventional model and an inverter, in addition to being available in a wide variety of designs, capacities, colors and more.

In addition to this, if you are concerned about calculating electricity consumption, you can also opt for an A+++ inverter air conditioner, that is, the highest category on the energy consumption scale.

Advantages of an inverter air conditioner

One of the main and almost obvious advantages of having this technology is that the consumption of an inverter air conditioner is considerably less than that of a conventional model, since it offers better energy management and can save more on electricity.

It is also noted that its useful life is usually longer, since, by not having to activate and deactivate components at all times, they are prevented from wearing out and can work longer.

On the other hand, something that adds to the ergonomics of this equipment is that it can be used remotely, thanks to the controls for inverter air conditioners, so you can manage its functions without having to leave the sofa.

And in case the remote is damaged or lost, don’t worry, since you can choose one of universal compatibility, avoiding inconveniences when pairing it with the equipment.


How much does an air conditioner consume?

In many cases, how much an air conditioner spends is a concern that may be present for many users. The electrical expenses at home can be high, which is why it is necessary to calculate the electrical consumption in kWh, before choosing any model.

Taking the frigories to kW of a certain model, whether it is an inverter or not, can help you calculate the electrical consumption of an air conditioner, in order to avoid choosing one that is expensive to use.

To do this, you will only have to multiply the number of frigories by 0.86. This will give you the consumption in kilowatts per hour of the equipment. In case you need to convert the BTUs to frigories, you will have to divide the element by 4.

Using this conversion could easily help you calculate the electrical consumption of an appliance in euros, since, by multiplying it by the price of each kW, you will be able to know how much it will cost to use it at home.

However, in general, air conditioners that use inverter technology, for the stable operation of the compressor, usually offer between 40% and 50% less electricity consumption, compared to the rest of the cooling equipment.

Inverter air conditioner consumption

Although, broadly speaking, an air conditioner with inverter technology is offered as an option that saves energy, you should know its consumption specifically; as well as its comparison against a standard one. Next, we will analyze some interesting numbers. 

While an ordinary 4,000-frigory air conditioner consumes a total of 4.6 kWh, a 5,000-frigory air conditioner will consume approximately 5.8 kWh. Therefore, it is very relevant to calculate the kw/h before choosing which inverter air conditioner to take home.

Bearing in mind that this data may vary depending on the capacity of the equipment, as a reference you can consider that, unlike those mentioned, a powerful model, for example, with 12,000 BTUs or 3,000 frigories, will only consume 3.5 kWh if It has an inverter during startup. Later, you can cut this figure in half, to deliver the promised savings.

In this sense, when evaluating a 3000 frigories inverter air conditioner, you will be able to notice a much lower consumption compared to other equipment and not only because of the reduction in energy requirements, but also because of the inverter function, to keep the compressor running.


In the face of a standard air conditioner and one with inverter technology, in the long term, the second will be cheaper, so we advise you to review the available models, to take advantage of the best offers.

In case you are worried about how much an air conditioner with a heat pump spends, you should bear in mind that, although they may be more practical throughout the year, they have a heating element that, added to the compressor, may be the equipment that uses the most electricity. consume within these categories.

Due to this, we advise you to prefer a low consumption air conditioner with inverter technology, since the advantages are quite obvious and you will be able to enjoy the same or even a higher level of comfort at home than before.
