I didnt take any more pics but without telling you can you imagine what kind of shape the rest of that package unit is in ?
Ill let you in on something, its a rust bucket with huge sheetsof insulation missing from the roof and panels.
Blower wheel is corroded to hell and it has no heat.
It sould have been replaced but some hack company jerry rigged a ICP 20 ton condensing unit in there to get the bid.
Im seeing more and more of these lately. Its not a high roof and its easily accessible with a crane. Just because some building owner felt like saving some money doesnt make that repair acceptable.
