Our licensed technicians replaced an old HVAC system in the customer's house in San Diego, California and installed a new HVAC 127ANA048000. It was a tricky job because the customer's attic had bad insulation. Our technicians had to use the infrared camera to make the measurements and start the work. Firstly, our technicians dismounted, hauled away and recycled old insulation. After that they started the HVAC 127ANA048000 installation according to the building standards. The HVAC-system installation consists of installations of new furnace, new evaporator coil, new outdoor condensing unit and new refrigerant line set.
