A 1.5-ton air conditioner typically requires a voltage of 208 to 230 volts to run the compressor effectively. From your statement, it seems like you have a voltage supply of 185 volts, which is lower than the required voltage for the air conditioner to function properly.
Running an air conditioner at a voltage lower than its rated voltage can lead to various issues, including the inability to start the compressor, reduced cooling performance, and potential damage to the AC unit over time. It's important to have the correct voltage supply to ensure the proper functioning and longevity of the air conditioner.
If you have access to a voltage stabilizer or regulator, you can use it to increase the voltage to the required level for the air conditioner to work correctly. However, it is crucial to consult a professional electrician or HVAC technician to assess your electrical setup and provide the best solution for running the air conditioner safely and efficiently. Attempting to modify the voltage supply without proper knowledge can be hazardous and may cause damage to the equipment or pose a safety risk.
