1. An HVAC system comprising:
a heat exchanger coil installed within a housing, the heat exchanger coil operable to exchange heat with air in the housing via a refrigerant passing through the heat exchanger coil;
an HVAC sensor assembly installed within the housing, the HVAC sensor assembly including:
a refrigerant gas sensor; and
an orientation sensor positioned to detect an orientation of the refrigerant gas sensor;
an air handler having a blower; and
a controller configured to prevent an operation of the air handler in response to detection that the refrigerant gas sensor is not in a desired orientation.
