Performed precision AC tune up on both systems. Tested power distribution system and corresponding starting components. Checked operating refrigerant pressures to ensure peak performance and efficiency. Found downstairs system low on refrigerant. Determined this was result of leak inside evaporator coil. Recharged system with 410a as temporary measure per customer request. Cannot guarentee how long refrigerant will last or remain inside the system. Found compressors drawing high amperage during initial start up. Installed start assist kit on both condensers to lower starting amperage. Load shedding purposes which will also ensure proper compressor operations when relying on generator back up power. Purged drains and used alkaline treatment to reduce bacterial growth within drains. Washed outdoor coils to maintain heat rejection.
