Thats a common install for most of the south. The issue is you need access to the unit. If you don't mind moving that insulation for the tech go for it.

I have seen some units in these energystar rated houses where they cover the whole unit in sprayfoam. Basically makes it unserviciable.


Also that hanging ductwork is a common method lately and a very bad habit for HVAC installers to get into. They hang the ducts up high and the higher they are the hotter they are. I forget the temp difference per foot from top to bottom in an attic but its a huge difference. Its much better to have them buried deep in insulation. Very very few parts of the country and houses will ever have an issue with condensation on the ducts. If a house does have that issue burying the ducts usually remedies this anyway.
