A system, method, and apparatus for decreasing harmful emissions is provided. The system includes an aftertreatment system comprising an exhaust conduit that directs exhaust gas from an engine system; a heater coupled to the aftertreatment system and configured to provide heat; and a controller coupled to the heater. The controller is configured to: determine whether the engine system is idling; in response to determining that the engine system is idling, determine whether a conversion efficiency of the engine system is greater than a threshold value; in response to determining that the conversion efficiency is greater than the threshold value, determine whether a temperature regarding the aftertreatment system is greater than a threshold temperature; and in response to determining that the temperature of the aftertreatment system is greater than the threshold temperature, at least one of disable or partially disable the heater.
