This is a Ruud Achiever Seer 10 home unit. Appears to be in good condition. Electrical cut off switch is in sight. It appears to be quite a bit out of level from undermining and settlement. I am going to recommend that the unit be leveled out as for the compressor could inherit problems being out of level
Insulation on pipe need to be replaced to prevent condensation - typical maintenance .
Typically takes 10-15+ degrees off level to be a concern.
