Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes: a furnace having a furnace heat exchanger; and an indoor HVAC unit having a refrigerant heat exchanger. At least one of a component of the furnace and a component of the indoor HVAC unit are selectively removable from an airflow path of the HVAC system.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a system controller configured to receive an input of an energy budget for the HVAC system for a specified period of time, determine a set point for the HVAC system that will cause an amount of energy used in operating the HVAC system over the specified period of time to meet the energy budget, and operate the HVAC system at the determined set point.

Abstract: A heating, ventilation, and air conditioning (HVAC) system has an input configured to receive at least one of a first heating setting, a first ventilation setting, a first cooling setting, a first humidity setting, and a first air quality setting, at least one of an image sensor and a microphone connected to at least one component in the HVAC system, the image sensor and/or microphone being configured to capture data from a first zone, and a controller connected to the input and at least one of the image sensor and the microphone, the controller configured to control at least one of the first heating setting, the first ventilation setting, the first cooling setting, the first humidity setting, and the first air quality setting in response to receiving the data from at least one of the image sensor and the microphone.
