Back bed fan coil was pulled off wall & hanging by a string, this unit not usable Front Bed appears to have either a mechanical issue or an improper charge Liv Rm system & Frnt Bed appear to be operational altho the LR had a prior water complaint which was not evident at service All 3 systems will need AT MINIMUM Charge recovery Electrical wireing between fan coil & condenser completely reworked including service switches at the fan coils Back Bed fan coil needs refund (inspection of copper for kinks also) Liv Rm unit needs line cover There may be hidden issues which could not be addresses during today's visit as they may be concealed It is evident there was no permitting for these systems
