The Air Conditioner and Heater is a versatile and efficient air conditioner that can be controlled via the Friedrich Go app from various devices. It is installed in the wall, extending only about 3 inches into the room, and uses a standard 115V 3-prong outlet. With 8,000 BTUs of cooling power, it can keep rooms from 300-350 sq. ft. comfortable in summer and add warmth to rooms that are typically too cold in winter. This unit is ideal for temperate winters and can be the primary source of heat for infrequent cold days. Wi-Fi connectivity is crucial for energy efficiency, as it allows users to program schedules and adjust settings and usage even when not home. The unit can also be controlled using Amazon Alexa or Google Home.
