The minimum voltage required for a 1.5-ton air conditioner to run the compressor can vary depending on the specific model and manufacturer. However, most residential air conditioners typically require a minimum voltage of around 208 to 230 volts to operate the compressor effectively.
It's important to note that the voltage requirement can differ based on the specific electrical system of your location and the design of the air conditioning unit. Some air conditioners may have different voltage requirements or may be designed to accommodate a range of voltages.
If you are uncertain about the voltage requirements for your specific 1.5-ton air conditioner, it's best to consult the manufacturer's documentation, which should provide detailed information on the voltage and electrical requirements. Additionally, if you are installing or troubleshooting an air conditioning system, it is recommended to seek the assistance of a qualified HVAC technician who can ensure that the electrical supply meets the necessary specifications for safe and optimal operation.
