I am contemplating installing a packaged heat pump - i.e. has stand
alone air handler as I have have no furnace now. Two questions 1) it
is OK to have the air handler in an upheated crawl space under a deck,
as opposed to under the house in a 20" crawl space. There is much more
room under the deck? 2) the best deals on are on R22 units - any
problems going with this older technology?

A packaged Unit is one in which the AHU and Condensing
unit is in one package.
The system you are describing is called a split system where
the AHU ( Indoor Unit ) is split from the ( Outdoor Unit )
condensing Unit.
The positioning of these Units relates to Duct and Pipe runs
which should be as short economical and direct as possible

The Refrigerant of choice should be ( R410A ) not R22 as
this refrigerant is due to be phased out.

Incidentally Packaged Units are often overlooked by
home owners who wish to install there own A/C Units

These Units are fully Piped up and Pre-charged with
refrigerant and require only additional wiring for power
and control
..
The installation of these Units then comes down to Duct
layout Supply and return.

There are manufacturer requirements for clear space around th
condensor and for access to the air handling unit. They will be a bit
different from unit to unit.

R22 is proven reliable with a competent installer.
