I checked all three systems. The mini split for the Office is producing a poor temperature split and possibly has a leak. Recommend getting proposals on replacing it. The installation of the unit does not look like it was done professionally. The unit on the master bedroom side is suffering from excessively high return air static pressure. Would recommend some sort of ductwork modification to remedy the issue. This unit suffers from excessively high starting amperage and recommending a soft in rush to help prolong the life of the unit On the main house unit over the garage. I found the insulation for the coil door missing and should be replaced. this unit also suffers from the high starting amperage and recommend a soft inrush kit
