On arrival systems running and cooling producing 18 degree deltas. Indoor units mostly clean and drain lines flowed when flushed. Neither system had water safeties or sediment traps and the older system had flex line running directly to gas valve in furnace. Explained why these code violations were important. Cust declined to fix at this time. Outdoor units passed all electrical testing but overamped on start up. Recommended soft start or compressor saver kits to address this and increase longevity of compressors. System cooling as I left.
