Sure sounds like it.
Hope hes done a room by room manual T..NOT a J and then, a proper manual D
to insure that his BTUh load on each room is handled.

>Hello,

>What does the "duct" connection on the Packaged unit look like?

You have a supply and a return duct that are usually square or
rectangular and large. Nine are about 30" x 24" for a 5 ton package
heat pump.

>How big is it?
>What size ducts does it feed?

It feeds the room headers whatever size is indicated for the volume in
each room
>Can the ducts from a Split Unit (or other kind of central furnace/air
conditioner)
>be used?

Only if you can get the main supply and return ducts to the old plenum
from the outside package.


>Where can i see pictures of the duct-work hooked up?

Most HVAC suppliers have web sights that show pictures of the units
with the duct connections sized and shown. Get a WW grainger catalog.

Package units are used in several situations....lack of crawlspace or attic
room for an air handler, someone does not want to loose a closet for an air
handler, or just for the speed that they can be installed on some homes.
If you have an attic, you would be better off going with a split system, and
being done with it. Its going to cost a bit more, but you will have a more
silent system, and you can get units with higher SEER and HSPF ratings than
you can in a package unit.
Package units are NOT just for mobile homes.

As far as a heat pump in Florida....its your best way to go. Period.
Make sure you get the highest HSPF rating you can afford, and the SEER
rating will be right up there with it.
You can NOT heat any cheaper than a heat pump in the southern states, but
make sure that the contractor that is sizing this out for you does a proper
heat load calc, and sizes the secondary strips properly.
