Abstract: Example embodiments of the present disclosure relate to a method of commissioning an HVAC system and a related unit. Some embodiments of the method include providing a unit of the HVAC system with a plurality of condensate outlets such that the unit may be installed in a plurality of orientations; installing the unit in a preferred orientation; selecting one of the condensate outlets from the plurality of outlets that is positioned to receive condensate based on the preferred orientation; attaching a condensate line to the selected one of the condensate outlets; and installing a sensor along the condensate line, the sensor configured to detect a presence of a refrigerant that is heavier than air and would flow with gravity along with the condensate collected by the unit.

Abstract: Devices, systems, and methods are disclosed for reducing leakage current in compressors, such as for HVAC systems. Several embodiments include a leakage current suppressor configured to reduce passage of electrical current into the housing of a compressor via a conductive pathway between an electrical conductor and the housing. For instance, the leakage current suppressor may sufficiently reduce the passage of electrical current into the housing of a compressor to prevent tripping a GFCI. In many embodiments, the conductive pathway may be formed, at least in part, by a liquid refrigerant in the compressor housing.

Abstract: Methods and related systems for operating a furnace are disclosed. In an embodiment, the method includes activating a burner assembly and a first fan of the furnace to combust fuel and air and circulate combustion gases along a flow path extending through a heat exchanger of the furnace. In addition, the method includes operating a second fan of the furnace to circulate air across an external surface of the heat exchanger of the furnace and produce a conditioned airflow. Further, the method includes monitoring one or more parameters of a motor of the second fan indicative of an airflow rate of the conditioned airflow, and deactivating the burner assembly, whereby combustion of the fuel and air in the furnace ceases, in response to the one or more parameters indicating that the airflow rate is less than a minimum airflow rate.
