• Voltage: Most residential AC units operate on either 120 volts (for smaller units) or 240 volts (for larger, central systems). Incorrect voltage can lead to underperformance, damage, or complete failure of the AC unit.
• Amperage: Amperage represents the amount of electrical current the AC unit draws. Each unit has a specified amperage requirement, which is usually listed on the unit’s nameplate. Exceeding this amperage can trip the circuit breaker, while insufficient amperage can cause the unit to run inefficiently or fail to start.
• Circuit Breaker: The circuit breaker is a safety device designed to protect your electrical system from overloads and short circuits. When the amperage drawn by the AC unit exceeds the breaker’s rating, the breaker will trip, cutting off power to the unit.
• Wiring: The wiring connecting your AC unit to the electrical panel must be of the correct gauge to handle the unit’s amperage requirements. Undersized wiring can overheat and pose a fire hazard.
