Abstract
The present invention provides a heating, ventilation, and air-conditioning (HVAC) system using an A2L refrigerant and a method of installing the HVAC system in a building. The HVAC system includes an indoor unit having a heat exchanger that uses an A2L refrigerant, a blower, an outdoor unit, an A2L control board, and one or more A2L sensors configured to detect an amount of A2L refrigerant. In one or more embodiments, the indoor unit is electrically coupled to the blower, the A2L control board, and the outdoor unit. Also, in one or more embodiments, the A2L control board is also electrically coupled to the blower and the one or more A2L sensors.
