A manual D, is the ACCA guide to insuring that the ductwork is of the
correct size, to insure not only correct BTU delivery to each room, but to
insure correct sizing of duct to make sure that CFM and velocity are
wtihing the correct guidelines for the unit in question.
It also takes into consideration, filter area, and all items in the
airstream, to maintain the correct static pressure for the unit to operate
correctly.

since I don't know what Manual D is.. I'm 99% sure they did NOT.

Explain.. and I'll press them.

They did not install the furnace nor ductwork.. just the AC. But the
"comfort specialist" said the ducting was adequate.
