Vintage Hang-On AC

torque395 on Wed July 01, 2009 10:25 PM User is offline

Year: 1977
Make: Ford
Model: ??
Engine Size: 2.3
Refrigerant Type: Was R12
Ambient Temp: 85
Pressure Low: 0
Pressure High: 0
Country of Origin: United States

Today I was browsing craigslist and ran across a "Vintage Hang-On Air Conditioner" for sale for $50. Compressor, evaporator unit, hoses, drier and condenser. I bought it impulsively. I looked at it, the blower works and the compressor has compression being turned by hand. But. I noticed that the hoses clamp on with a hose clamp on ALL the fittings except on the evaporator itself. This means both the high and the low side are clamp on hoses. How did this ever work? And will it work again with R134a? I would think 200-ish PSI that the high side will build up to would cause those hoses to blow off, with them only being clamped on. I have never seen a condenser with clamp on ends before. The YORK compressor appears to be dated 1977.

Any thoughts? Maybe i could clean this up and re-sell it. The evaporator unit is not as nice as i'd like it to be but it does work. The ad says the unit is a WARDS unit. I've never heard of that before unless it was something Montgomery-Wards sold??

Hi torque; Clamps were never put on a factory setup to my knowledge, but many after market A/C units had them. They did work ok and would hold pressure if you remembered to tighten them occasionally. There were many places that installed units like yours in cars that did not come from the factory, and they did a brisk business for years. Remember that most older cars were large vehicles, and had ample cooling capacity to handle the bolted on units. The connectors have several convolutions at their ends, making a good seal when tightened up. They were a bear to put into the hose.

Thanks for the reply. If i want to replace the hose what kind of hose do i need to get? Its just some rubber hose that looks like heater hose, but i imagine it is more than the ordinary heater hose.

You need to use auto ac refrigerant hose which is now barrier hose. This type of hose requires that you use crimped fittings.

So to replace the hose I will need to replace the drier (which needs replaced anyways) and the condenser since they are both clamp on style components?

Being from the 1970's, it's almost certainly a simple tube and fin condenser. A modern condenser will give much better performance, especially with R-134a. You're going to end up using the evaporator unit and the compressor, and replace the rest.

I would toss the York also and use an adapter plate and Seltec compressor.

Sounds like I need to clean this AC unit up and resell it. I don't like the idea of hose clamps on the hoses, and if i buy a new condenser and hoses and compressor all that's left is a new evaporator which can be had for as little as $140.

I paid $50 for this setup and i think if i clean it up real good i could resell it for $75.
