Cheap AC

So...... It has been about 106 for about 2 weeks now. Every summer about this time I start wishing my daily driver '69 F100 had AC.

I was talking to a friend of mine today at Motorfest and he said that I could probably get AC in mine for less than $600 dollars. But that price is still out of my current College student budget. We are trying to install forced air in our house and can't afford the duct work currently, my wife said no AC in the pickup untill the house has AC. Bummer.

So I was on Ebay looking for under dash units and came across some for about $50 bucks for just the unit.

I have often wondered about using the AC out of a newer vehicle and making it fit in the ol Ford. Not sure about that can of worms though. Any suggestions/ideas on this one?

The 1960/64 Galaxie 352/390 with hang on factory air can be used on a 352/360/390 1965/72 Ford truck. All the underhood components (compressor/brackets/pulleys/condenser/dryer) will work, the hang on unit bolts under the dash. These early airs were separate of the heater, so there's no duct work to worry about. Buying just the underdash unit without the rest of the parts is a waste of time. You need to get everything off one car. The only thing you will need to do is change the belts and have new hoses made.


After 1964, all the passenger cars with FE engines A/C units are integral heater/air combinations, and won't work on an F series truck.

So what about the feasibility of retrofitting a AC/heater out of something newer like an Explorer or something? Am I crazy?

How can you make it work? The Explorer air conditioning/heater is all integral to the specific vehicle...no can do. You need one of the older style hang on units, these units are separate from the heater. The hang on portion has the controls and the evaporator in one unit.

I wanted the the heater/AC integral, that way the heater air is dried so that in the winter and during the rainy season my windows would not fog up anymore. I could make a panel to hold the controls for it. the early Explorers had small dash space if I remember correctly. Just a thought I have thrown around in my head for years.

If I had the money, I would run a Vintage Air setup. But I don't so I can't.

I just purchased a factory AC unit out of a Junk Yard out of a 1971 Ford F100 for $125. Got the compressor, brackets, under dash unit, condensor, etc. After replacing everything I think I will have about $400 in it. If you did not replace the heater core (highly recomended) and did not have to change the blower motor and the compressor or the Clutch you could get by pretty cheap (chances of this are pretty slim). I of course have some R12 that I bought about 30 years ago for .89 - If all my other investments had only been so profitable! Good Luck!

1968/72 F100/350's also had a dealer installed A/C option that was not integral with the heater. It looks very similar to the factory A/C. Both use a similar unit that bolts under and follows the curve of the dash.

I see quite a few bumpsides in the wrecking yards around here with aftermarket A/C and have even found two with the factory A/C. (Factory A/C has the controls integral with the heater controls and has the evaporator up behind the glove box, and so has a very shallow glove box.)

Mine has aftermarket A/C installed, just needs to be charged. (I pulled a vacuum on it and it held quite well...just wish I had some of your R12, someone stole my last 2 cans!)



So don't overlook the wrecking yards as a possible source of an A/C unit, and as Bill and George said, get everything off the truck including compressor and mounting brackets, condensor (in front of the radiator) drier and hoses.

Is it possible to retrofit an R12 AC to the new refridgerant?
Are the new Vintage Air AC's R12?

I would think that any new aftermarket system is designed for R134A. R12 hasn't been manufactured for over ten years now and most remaining supplies are either NOS or reclaimed and filtered refrigerant. So it's still availbale, but it's expensive and you have to be A/C certified to legally buy it.

An older R12 system can be converted with a bit of work. Rather than my typing it all out, just click on the link and you can read about most of the process:

Just remember that when you change these older systems over to R134 they don't always cool well at idle or lower engine RPM. I don't think that the old style compressors build enough pressure to make them cool as good as the new systems.

Part of the problem is that R134A needs a bigger, more efficient condensor to radiate the heat out of the system so R12 condensors don't always work as well. Once you get up to speed and there's more airflow through the condensor it helps, but at low speed it's not as efficient a heat exchanger.

Thanks Tiger Dan - I always thought it had to do with pressure. So if I put a larger condensor on my system it may help with the cooling at lower speeds?

Thanks

Yes, to a certain degree. It also has to do with the design of the condensor. Parallel flow condensors are more efficient than the standard tube-and-fin condensors, althought they tend to be on the pricey side. Here's a little more info, and the site this is on is worth poking around a bit:
