Hello Handsome Dan, it’s true that AC units have a startup surge. Depending on the unit it can be 1.04 to 2.00 times the running wattage. Now, in the worst case, an 11 amps Frederich 15,000 BTU unit will have a 22 amps surge. But most likely, the max. amps are much lower; below 15 amps. Hello Shayan, the table is calculated based on two factors; 1) BTU cooling output, 2) EER rating. Based on these two factors, you can calculate the wattage. With known voltage (115V circuit), you can calculate the amps. Hope this helps. Reply From what I understand I would need at least something that can handle 22 amps, 2540 Watts? Meaning a 15 amp circuit would be overwhelmed and even a 20 would be as well? I jest in my statement: that seems like a rather niche market. As a 30 amp circuit, to me is what my stove is on. Are there exceptions to this rule? Esp with newer air conditioners? As a layman I appreciate your blog and wonder why the manufacturers don’t list maximum amps needed instead of running amps. Yes, 5 amp is a continuous draw. For batteries, that will be 5 amp-hours; that’s the more relevant information there. However, you need to take into account voltage as well. What really matters is watt-hours. Usually, you have 120V and 5 amps which equals 600 watts; hence 600 watt-hours. Batteries don’t run on 120V; instead, most of them run on 12V. To achieve 600W at 12V, you will need 50 amps; so the draw would be 500 amp-hours (instead of 5 amp-hours). Watt-hour draw, however, will be the same for 12V and 120V voltage. Reply

Example 3: 18,000 BTU unit draws a little less than 20 A. How To Calculate The Number Of Amps An Air Conditioner Needs? We see that this AC unit uses 7.25 amps to deliver 10,000 BTU of cooling power. Comparatively, the 5,000 BTU AC unit from Example 1 delivers 5,000 BTU of cooling power using 4.35 amps. When u mention draw of AMPs ( 5. Amps ) that’s 5 amps per hour. So a 5 amp ac will pull 5amp hours for every hour. Trying to set up ac on battery and which is better running a inverter or not and how many AH will be required Reply If you were me would you take a chance in putting said 15,000 btu air conditioner on a 15 amp circuit? You’re right, we don’t have adequate knowledge about these surge wattages/amps because manufacturers don’t really include them in the specification sheets. Hopefully this would change in the future.

Can I run two 5000 btu 115v window air conditioner on a 15 Amp breaker or should I have them on separate amps? Also what type of extension cord would I use if I need to plug it into another outlet that is connected to a 20 Amp breaker? My room and my mom’s room power outlets share 15 Amp breaker. I can run an extension cold to the washer outlet in the bathroom that is on a 20 Amp breaker. I already know not go have my air unit on and the washer going at the same time. Thank you for the help. Oh, this is the air conditioners I’m going to be using Midea 5,000 BTU 115V Window Air Conditioner with Remote, White, MAW05R1WWT Reply Example 2: How many amps does a 12,000 BTU mini-split use? We can see from the air conditioner amperage chart that it draws about 13 A. The higher energy-efficiency device from Example 2 (12 EER) delivers 100% more cooling power than the 5,000 BTU device from Example 1 (10 EER).

Let’s take a small 5,000 BTU unit with EER 10. We also know that the electrical potential in the outlet is 115V. Here is how we calculate the amps required to power the unit: Example: Some homeowners are interested in how many amps does a 5,000 BTU air conditioner use. Of course, you also have 6,000, 8,000, 12,000, 15,000, and 18,000 BTU devices that use more amps than 5,000 BTU units. I heard air conditioners will draw sometimes twice to three times the amount of power on start up. Is this true? For instance, if I wanted to run a Frederich 15,000 BTU with the following specs: 115 Volts 11 Amps 1270 Watts 11.8 EERStay cool this summer with our range of air conditioning units! Our selection includes top brands like Meaco, Midea, Honeywell, and more! Portable air conditioners are a great way to keep your home cool and comfortable during hot summer months. They are easy to install, require minimal maintenance, and can be moved from room to room as needed. Portable air conditioners also provide more flexibility in cooling specific areas of the home without having to invest in an entire central air system. Whether you're looking for relief from the heat or just want added convenience, portable air conditioning is a smart choice for any homeowner. Example 1: You can see that the 5,000 BTU unit (be it window AC or portable AC) draws a bit more than 5 A. The best battery-powered unit – the Zero Breeze Mark 2 – can deliver 2,300 BTU of cooling power with just 24V electrical potential. The electrical current (measured in Amperes or ‘ amps‘ for short) needed to run an air conditioner is directly proportional to how much the AC unit will affect your electricity bill.

Hi, I’m a mathematician so your formula 1 and 2 interests me. I wanted to suggest to use the multiplication symbol for multiplying and the divide symbol for dividing. 13,500 is not equal to 1500 divided by 9. EER is Energy-Efficiency Rating that you can usually find in specification sheets of 5,000-18,000 BTU AC units. On average, EER ranges from 8 to 12. These numbers are also used to calculate the Amps intervals in the table above). Hello Ludy, you’re right, the most energy-efficient 10,000 BTU AC would be the best. As far as window AC units are concerned, you can’t get much higher than the 12 EER rating. In short, you’re looking at the right units. Only Midea U Inverter has a higher 15 CEER rating (you can see how energy-efficient the other 10,000 BTU AC units are here). Table: How Many Amps Do Window, Portable, Mini-Split Air Conditioners Draw Air Conditioner CapacityI (in Amps) = Air conditioner capacity (BTU) / (EER x V (in Volts) Example 1: 5,000 BTU Window AC With EER 10 From the table above, it’s evident that window and portable air conditioners can draw anywhere from 3.52 amps to almost 20 amps. The Prem-I-Air 8,000 BTU Portable Air Conditioner offers tailor made indoor climate control. This 3 in 1 unit boasts air conditioning, dehumidifier and fan options. Another nice tweak for demonstrating calculations is to have the correct number of digits and decimal places, such as showing 1500 for the number 1500 rather than 15000. Just a nice tweak, so it’s not off by, oh, a factor of 10 or so. Thanks. Reply
