How many Amps does an air conditioner use?

The electrical current needed to run an air conditioner is related to the amount of electricity you use.

People are interested in the number of Amps used in an air conditioner.You have thousands of Amp, 8,000, 12,000, 15,000, and 18,000 BTU devices that use more than 5,000 BTU units.

The table shows how many Amps the air conditioners draw.There are factors that determine the number of Amp needed and how many Amps your air conditioner uses.

From the table, you can see that window and portable air conditioners can draw anywhere from 3.52 Amp to almost 20 Amp.

The AC unit of 5,000 - 18,000 BTU is estimated to draw on the chart.

You can see that the 5,000 BTU unit draws a bit more than 5 A.

How much does a mini-split use?The chart shows that the air conditioner draws 13 A.

We usually size air conditioners based on capacity.This is where you can see how the size of AC units is calculated.

You can usually find EER in the specification sheets of AC units.EER can range from 8 to 12.The numbers are used to calculate the Amps intervals.

The power of an electrical device is calculated using a formula.The majority of AC units are powered by 115V.If we know P, we can combine the two equations to calculate how many Amps an air conditioner needs.

We are going to take a small unit with EER 10.The electrical potential in the outlet is 115V.Here is how the unit is powered up.

The higher the air conditioner's efficiency, the less power it will draw.We will pay less for electricity and still get the cooling power.The window air units with an EER rating above 11 are the most energy efficient.You can find the best window AC units here.

A portable air conditioner with an EER rating of 12 or more is the most efficient.Let's take a portable AC with EER 12 and power it with 115.Here is how we can figure out how many Amps the air conditioner draws.

The AC unit uses 7.25 Amps to deliver 10,000 BTU of cooling power.The 5,000 BTU AC unit from example 1 uses 4.35 Amps.

The 5,000 BTU device from example 1 delivers less cooling power than the 12 EER device.

It doesn't draw as much as it could.It draws more power to achieve a more powerful cooling effect.It is more cost-effective.

One of the most convenient AC units is battery-powered.The batteries can not produce a high electrical potential.We don't deal with 115V because of that.The air conditioners use a parallel connection.

The Zero Breeze Mark 2 can deliver 2,300 BTU of cooling power with just 24V electrical potential.

It needs 27 Amps to power the whole unit.That is more power than is needed to power an 18,000 BTU portable air conditioner.

You always want to invest in an air conditioner that has a higher EER rating.A higher EER rating can reduce the electricity consumption of an air conditioner.

If you have a question about how many Amps your air conditioner draws, you can check the specification sheet or give us the specs in the comments below, and we will try to help you figure it out.

What is the EER for the Coleman RV roof top?It is a power saver for the manufacturer.Thanks.

Hello Bob, that's right.Coleman produces 13,500 BTU with max.1500W is the wattage.The EER rating is 13,500 BTU/ 15000W.You can check out other RV rooftop AC units with high EER rating here.
