How Many Amps Does A Window Air Conditioner Use

The total watts all depends on how energy efficient the manufacturer made the appliance.

How many amps does a window air conditioner use.

Some units offer interchangeable cords while other need to be ordered with the correct cord preattached. Units are available in either 15 20 or 30 amps. For example an 18 000 btu 230 volt air conditioner draws approximately 8 amps of power. So how do you find out how many watts does a window ac use.

Each 120v circuit in your house is rated for between 15 and 20 amperes and the 240v circuits are rated for 30a. Do you have the best window ac. 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. Below you find a table of how many watts do different air conditioners from 5 000 btu to 18 000 btu use.

Use btu and eer rating to calculate how much power does your air conditioner use. A 10 000 btu unit has surge wattage of 1800 watts and a running wattage of 1200 watts. Most ptac units are plugged in although they can be hard wired if desired. Check the product manual.

To see the different plug faces and how many amps they handle click here. Look at tech specs on the manufacturer s or selling company s website. 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. Air conditioners of this voltage are considered permanently mounted even if they are window models because a special 230 volt outlet will be installed at the point of use.

You can divide the btu by eer rating something like 5 000 btu 10 eer 500w. A 12 000 btu unit has surge wattage of 3950 watts and a running wattage of 3250 watts.
