Rural ingenuity at it's finest. This was done before those god awful oil packs were on the market. As you can see it's a horizontal Thermopride with a lovely sheetmetal box built over it. The second pic is the slab case ac coil right before the duct goes under the old farm house. The last pic is how it all looks when I walked up on it Looks like crap but I guess it works been there 20+ years. More reliable than an oil package unit and you sure was'nt going to fit it under the house I don't know how they even got the duct in there 12 inches or less high in most places.
