A 14 gauge extension cord can handle much of this current but we all know that air conditioners require more electricity and power when it comes to the initiation or starting up.

A larger number of gauge means the wire will be thinner in size, it eventually means that the wire will carry less power and may not be able to handle heavy appliances such as air conditioners. 10 gauge is probably the thickest and most powerful wire when it comes to different choices between extension cords.

Do keep this fact in mind that higher gauge extension cords will also work for shorter distances as they may not be able to transfer current consistently for a relatively long distance. A 10 gauge extension cord for the air conditioner can be 100 feet in length allowing you to cover a large area between your air conditioner and its outlet.

The length of the wire also affects the amount of current. For example, a 12 gauge extension cord of 25 feet can easily handle 16 to 20 amps of the current while the 10 gauge extension cord of 100 feet will carry this current without any hassle. It means that if there is a short distance, a 12 gauge extension cord may work perfectly but you definitely need a 10 gauge cord for a distance longer than 25 feet.
