Serviced a rooftop heating and air conditioning system (RTU) at Elks Lodge in Roy, UT. The system uses both R410A and R32 refrigerants. Replaced the blower motor, which was malfunctioning and affecting airflow throughout the building. Additionally, installed a REME HALO air scrubber with UV-C lights to improve indoor air quality by reducing airborne contaminants such as mold, bacteria, and viruses. After installation, tested the motor and scrubber to ensure smooth operation and efficient air circulation, providing the lodge with improved climate control and cleaner air.
