13 Amps
A 4-ton air conditioner typically draws between 13 and 16 amps of electricity. This amperage draw is influenced by factors like the unit's efficiency rating (SEER), the voltage of your electrical system, and the thermostat settings.
Higher SEER ratings generally mean lower amperage draw.
Factors Affecting Amperage
- SEER Rating: Higher SEER ratings indicate greater energy efficiency, leading to lower amperage draw.
- Voltage: Standard residential voltage is 120V or 240V. 240V systems often require less amperage for the same cooling capacity.
- Thermostat Settings: Running the unit at higher cooling settings will increase the amperage draw.

Calculating Your Electrical Needs
To determine if your electrical panel can handle a 4-ton air conditioner, you need to calculate the total wattage. Multiply the amperage (13-16 amps) by the voltage (typically 240V) to get the wattage. This will result in approximately 3120-3840 watts.
Consult a qualified electrician to ensure your panel has sufficient capacity. Overloading your electrical panel can be dangerous.
