How much electricity does a 5000 BTU air conditioner use

If you want to spend money on an air conditioner that consumes a lot of electricity to function you would probably want to get your hands on the most efficient air conditioner. Getting a powerful air conditioner is not always the solution for us because it would consume too much energy and maybe not work the way we want. 

Similarly, we wouldn’t want something that is not powerful enough for our homes and will probably be a waste of both money and other resources. If you are searching for a basic air conditioner model then you may have come across units like a 5000 BTU air conditioner. 

Just like we have mentioned above a lot of times you will come across the acronym BTU which is the short form for British thermal units. Multiple air conditioner manufacturers use this term to describe the capacity of an air conditioner instead of using wattage or amperage which makes it harder for people like us to understand. You can obviously convert the term into wattage or amperage and find out how much electricity does a 5000 BTU air conditioner use

What is the meaning of BTU?

As mentioned earlier, the acronym BTU refers to the British Thermal Unit. With the help of the particular metric, you will be able to find out the functional capacity of an air conditioner. With one BTU, one pound of water can be heated by one degree Fahrenheit.

The air conditioning unit available in the BTU is 5000 BTU, 6000 BTU, 8000 BTU, 12000 BTU, 15000 BTU, and 18000 BTU. The use case of these air conditioning units depends on the size and space of the room they are going to be used in. 

It is important to understand how powerful a heating and cooling system is and how much space it will be able to control. HVAC systems are measured in BTU to make it easier to understand how powerful a system is.

Amount of electricity used by a 5000 BTU air conditioner

If you are looking for the answer to your question: how much electricity does a 5000 BTU air conditioner use? You can simply use a calculation method to find out the amount of electricity used by the appliance. Here is how you can do it:

Check out the BTU rating: 5000 BTU

With the help of the BTU rating of an air conditioner, you will be able to identify the amount of heat the appliance can remove from your room at a given time. As the BTU rating of the air conditioner increases the more functional it becomes in supplying cool air in a large space. 

Although we are currently trying to find out the energy used by a 5000 BTU air conditioner, in the case of other air conditioning units you can check the back side of the AC to find out about its BTU. The capacity can range from 5000 BTU to 28000 BTU. 

If you come across another unit for measuring the capacity of the air conditioner known as ‘Ton’ you don’t need to worry about anything because you can always convert it for calculation. 1 ton is equal to 12,000 BTU (using this conversion rate your calculation will become easier).

Pinpoint the EER rating

The next step would be to figure out the EER or Energy-Efficiency Ratio of your air conditioner. This particular rating helps in checking the energy efficiency of the machinery while it is being used. The EER rating of an air conditioner can be found in the same tag where you can find the BTU of the air conditioner and the EER ranges between 13 to 25.

If the EER rating of your air conditioner is on the higher side, it means the appliance will be utilizing less energy while functioning which in turn will reduce your utility bills. On average most BTU air conditioners come with an EER rating of 9.5 so we will be using this particular number during the calculation. 

Single out the voltage capacity of the air conditioner

Now that we already have the BTU and EER of the air conditioner, we need to identify the voltage capacity of the 5000 BTU air conditioner. The aim of evaluating the voltage system is to find out the flow of electricity between two points. If you have a higher voltage system then it will be easier to transfer electricity faster into the connection. 

Usually depending on the model of the air conditioner, the voltage rating can remain between 100 Volts to 280 volts. A 5000 BTU air conditioner typically comes with 115 volts or 120 volts. If you have a different model you need to check out the voltage of your air conditioner by looking at the label attached to the exterior part of the condensing unit. 

Conversion of EER and BTU into wattage

In order to find out the wattage of an air conditioner we need to divide the BTU rating by the EER rating of the air conditioner. Since we are trying to determine how much electricity does a 5000 BTU air conditioner use, we will be using 5000 as the value of the BTU rating and 9.5 as its EER rating.

BTU / EER = Wattage

5000 / 9.5 = 526.31 watts.

Converting watts and voltage of the air conditioner into amps

Since the amount of energy used by the 5000 BTU air conditioner can be measured through amps we just need to find out the amps to receive the final result. Diving the wattage of the air conditioner with the volt rating the same will give you the amps. 

Wattage / Volts = Amperage

Since we have already found out the wattage of the 5000 BTU air conditioner from the above-mentioned calculation we will be easily able to find out the Amperage of the air conditioner. We are using 115 volts as the voltage of the 5000 BTU air conditioner. 

Amps = 526.31 / 115

= 4.57 amps

With the help of this calculation method, you will be easily able to check out the energy usage of any air conditioner and find out if it will be an appropriate selection for your home or office space. Before finalizing your purchase you should also put equal emphasis on the EER rating of your air conditioner because it will definitely help you save a lot of money in the long run.

Final words

By now you must have come across the answer to your question: how much electricity does a 5000 BTU air conditioner use? If you are living in a small and compact house then you can easily use the 5000 BTU air conditioner to control the internal temperature of your home. 

Another additional advantage of using the 5000 BTU air conditioner is that you can easily use a solar system to operate the air conditioner. With an energy-efficient air conditioner model you won’t have to worry about huge electricity bills while running the air conditioner whenever required. 

Frequently asked questions

Does a 5000 BTU AC use a lot of electricity?

Although air conditioners are heavy power-consuming appliances a 5000 BTU air conditioner uses comparatively less energy than other air conditioners. For example, you can expect a 5,000 BTU window unit to use around 450 watts whereas a mid-size 8,000 BTU AC can consume 715 watts. If you are thinking about installing a bigger air conditioner (supposedly 14,000 BTU) then it will consume around 1250 watts. 

How much battery power is needed to run a 5000 BTU air conditioner?

In case you are opting for a cheaper alternative in the form of a lead-acid battery then you can expect the air conditioner to work for a maximum of 2 hours. 

Does the air conditioner consume a lot of electricity?

The amount of energy consumed by the air conditioner is dependent on the overall size of your air conditioner. From a general perspective, if you are using a central air conditioner then you can expect the system to consume between 3000 watts to 3500 watts every hour to function appropriately. On the other hand, window units can consume from 900 watts to 1440 watts every hour and portable units can take up to 2900 watts and 4100 watts per hour.

Can solar panels power a 5000 BTU air conditioner?

Yes, depending on the type of air conditioner you have selected for your residential usage and the overall capacity of the solar system you will be easily able to power up a 5000 BTU air conditioner.

However, you also need to note that to efficiently run the solar-powered air conditioner you also need to have a battery system installed with your solar system. In general, you can use a 4100 Amp-hour lithium battery along with 800 watts of solar panels to make your air conditioner function.

Can I run a small AC with solar power?

Yes, it is possible to run an AC with the help of solar power but you will need to install supporting equipment like batteries and an inverter with your solar system. The energy produced by solar panels is DC current but the air conditioners generally use the AC current which is why you must use an inverter to transform DC current to AC current and then only your cooling system will work.
