I arrived for a silver membership ac pm X3. I first inspected all indoor systems and found no issues with the systems operation. I then inspect all outdoor systems and found all condensers coils to be clean and all system to be running. I fought the bedrock system to be running low on refegerant charge. I made this aware to the homeowner and and we decide to Charlotte the systems to get it running properly. I added 2LBS of R410A to the system and set the superheat at 6 deg per management specifications. Overall all system are rusted per management specifications at this time.
