A 220V air conditioner is a machine that can help control a room's internal temperature that requires 220 volts of electricity to operate properly. To use such an air conditioner, an electrical plug offering at least 220 volts must be available.
These appliances come in two styles: a whole-home, central air-conditioning unit that pairs up with a central heating system, or a window unit designed to cool a single room. Central air conditioners come in 220-volt and 240-volt models, while window air conditioners come in either 110/120-volt or 220/240-volt versions; higher voltage denotes more power. When using air conditioning units with high voltage, including 220-volt systems, avoiding circuit overload is an important safety issue.
