Hi, my name is Lal Ding Liana, but I go by LD. I’ve been in the heating and cooling field for about seven to eight years. I started with an internship at Bell Brothers in 2016 while studying HVAC at DMACC. After finishing my Heating and Cooling Associate’s degree, Bell Brothers hired me as a full-time service technician until December 2019. That’s when I moved to the Durham-Raleigh area in North Carolina to help my family with their sushi restaurant business. While there, I also worked full-time for The Maintenance Team Inc., where I maintained the HVAC systems for the Brier Creek Corporate Center, including cooling towers, VAV boxes, FPB boxes, and Trane self-contained units. I also serviced HVAC units for their outside commercial clients. In January 2022, after my wife and child arrived in the USA, we moved back to Iowa, and I rejoined Bell Brothers as a Commercial Service Technician, such as repairing, maintenance, and services Rooftop units, VRF units, Boilers, Water Heaters. where I’m currently still working.
