Does low voltage affect AC cooling?
Maintaining consistent power to your air-conditioner will keep it running smoothly all summer. When the voltage is too low the motor will pull more than normal current and the temperature of the motor windings rise 10% to 15% for each 10% drop in Voltage. This can damage motors and wear on the life of your AC.
