Warranty- hooked up 8” return in basement, added armor flex to refrigerant lines in basement, added a bird screen for flu, left grilles and filters for customer (he didn’t want me to install grilles), added caps for AC, added foam blocks to drain line, and vacuumed and started up system. However compressor is not pumping. I will be ordering one from apex. Gas meter is also not installed yet so I was unable to start the heat. Pics and video uploaded
