Fuses are crucial safety devices designed to protect your AC system’s delicate electrical components from overcurrents. They act as sacrificial links, breaking the circuit when excessive current flows through them. This prevents damage to the compressor, fan motors, wiring, and other sensitive parts. Without fuses, a short circuit or power surge could lead to costly repairs or even pose a fire hazard. 24 Hour Emergency Heating Service Emergency Air Conditioner Repair Near Me 24 Hour Hvac Hvac Air Conditioning Service
