How many amps does my window air conditioner use.

Look at tech specs on the manufacturer s or selling company s website. 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. Amps 240 volts 1 phase. Chart showing how many kw and amp an air conditioner heat pump uses.

A rule of thumb to estimate how many watts of energy different air conditioners use is to take the btu number and divide it by 10. Small room size air conditioners generally in the 5 000 to 6 000 btu range will draw between 5 and 7 amps of power. But rough estimates for how many watts an air conditioners uses are. Units require anywhere from 15 60 amps depending on how many tons they are.

Your home air conditioner will be designed to work on either a standard 120 volt circuit or if it s a high powered unit it may take 240v which would require a special circuit in your house. That s how you can easily estimate that 5 000 btu ac units use 500w of energy. The total watts all depends on how energy efficient the manufacturer made the appliance. Click t o close window.

This is a new pop up window on top of your generatorjoe browser window. Do you have the best window ac. Central air conditioner 3500 watts central a c fan only compressor off 750 watts. Check the product manual.

Central air conditioning units require 208 240 volts. Below you find a table of how many watts do different air conditioners from 5 000 btu to 18 000 btu use. Central air conditioning draws extra power each time it turns on and you can t tell how efficiently the system is working. One 10 000 btu air conditioner may use 900 watts of electricity while another one uses 1 000 watts.

So how do you find out how many watts does a window ac use. Most common voltage ratings for ac units are 115 125 and 220 volts and amperage rating can run from 15 to 20 amps. Because the amperage draw is low other small household appliances can use the same socket as the air conditioner. 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.

Read carefully plan accordingly. In most cases these are plugged into a wall socket that is serviced by a 15 amp breaker.
