What is the difference between a 115 volt air conditioner and a 110 volt air conditioner?

The difference between a 115-volt and a 110-volt air conditioner primarily lies in the nominal voltage ratings, which reflect the voltage range that appliances can operate within. While 110 volts is often used as a general reference, many modern air conditioners are designed to operate optimally at 115 volts, which can better accommodate fluctuations in power supply. In practical terms, both types are compatible with standard household electrical systems in North America, and the difference is largely a matter of labeling rather than performance.
