Hi Paul,
To the best of my knowledge, the only way for you to get the original Piper A/C system installed would be to buy a used one from one of the aircraft salvage yards and install it in accordance with the Piper Parts and Service manual instructions.
We suggest you start your search with Preferred Airparts (www. preferredairparts.com) or Wentworth Aircraft (www.wentworthaircraft.com)
I don’t believe there are after market companies that sell FAA approved A/C systems for your Archer II.
Another option, that is much less expensive and readily available would be a portable unit powered by aircraft power that blows air cooled by ice into the cabin. There are some drawbacks; ice has to be loaded prior to flight, and the physical size will cut into back seat room, but these do cool the cabin during start up, take off and climb. Some pilots say it’s better than nothing.
For a look at some of the units that are for sale, type “Cabin cooler” into the search window at http://www.aircraftspruce.com.
Or, if you’re handy, go to YouTube and type “Hillbilly Air Conditioner” into the query window for directions on how to put together a working model using easy to get off the shelf parts.
Please let me know what you come up with.
Steve
