How Many Amps Does A Small Window Air Conditioner Draw

The lower two voltage ratings are common in smaller units while units with a rating higher than 15 000 btus will require a 220 volt circuit.

How many amps does a small window air conditioner draw.

A small ac unit will draw about 7 5a on a 120v circuit. The vast majority of mini splits require 208 240 volts. The total watts all depends on how energy efficient the manufacturer made the appliance. So how do you find out how many watts does a window ac use.

Small room sized air conditioners typically draw between 5 and 6 amps. Some smaller capacity units only require 110 120 volts. Current draw of air conditioners. There are 3 ways how to.

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. As far as lowering the air temperature is concerned you only need to know that it has 5 000 btu and it s correctly sized for your room space. For a small bedroom a 5 000 btu window unit should only use 450 watts a mid size 8 000 btu ac should use fewer than 715 watts a big 14 000 btu air conditioner should only use 1 250 watts even the least expensive units we researched for our review of the best window air conditioners got a score of 11 and all of our picks were rated 12 or 12 1.

Most common voltage ratings for ac units are 115 125 and 220 volts and amperage rating can run from 15 to 20 amps. An average 5 000 btu air conditioner uses 500w of energy running at full capacity. The current draw of air conditioners is rated in amperes or amps the basic unit of electricity that is equal to a constant current draw. A medium sized unit will draw closer to 15a on a 120v circuit so it will need its own circuit free from any other devices.

All mini splits require a dedicated circuit. Not knowing how many watts does a 5 000 btu air conditioner use is actually pretty normal. Types of air conditioners and their electricity requirements mini split air conditioner electricity requirements. Do you have the best window ac.

So it can be used on the same circuit with small devices. Check the product manual. Depending on the btu capacity amp requirements can range from 15 to 45 amps. Large ac units can draw up to 30a and need a dedicated 240v circuit wired for them.
