Claim 10:
11. A method for detecting a refrigerant leak, the method comprising:
causing, by a controller of an HVAC system, a blower of the HVAC system to direct air toward a sensor disposed in an indoor unit of the HVAC system, wherein the air is directed in a first direction that is different than a second direction of air flow inside the indoor unit;
receiving first feedback from the sensor;
determining, based at least in part on the first feedback from the sensor, that refrigerant is present in the air inside the indoor unit, wherein the first feedback indicates the presence of a non-refrigerant element in the air; and
causing the blower to direct the air out of the indoor unit.
