Yes, a dedicated circuit breaker for your air conditioner is strongly recommended and in many cases required by the Philippine Electrical Code to ensure safe and stable operation. A dedicated circuit means the air conditioner is the only appliance drawing power from that specific breaker, which prevents overloading, reduces the risk of tripped breakers during peak usage, and protects the unit from voltage fluctuations caused by other high-powered appliances sharing the same line. Have a licensed electrician install the dedicated circuit and circuit breaker before the air conditioner is set up, especially for units with a capacity of 1.0 HP and above.
