1967 Camaro AC Question

I have a factory A\C car and I am looking into the cooling system options. I see most people here use the Vintage Air or Classic Air, but what about restoring the factory unit. What is the disadvantages or advantages. Does it cost more for the restored system. Just seeing if anyone has something to share on these options.

In my opinion go with a vintage system. The vintage system is a refined system. All of the problems the original AC units of the past are taken care of. No cables, and a much more comfortable system that is user friendly. You could use the original system if you are worried about originality, but if you are not a original person , it's a no brainier to me. The price to rebuild your original system will be more money than a vintage system, and you will still have that massive antiquated compressor, and selector cables.

Re: 1967 Camaro AC Question

I own several factory air 1st and 2nd gen F bodies. I own one 1st gen with vintage air. I drive all my cars. I live in arizona.
It depends on the condition of your system. If it just needs a compressor, txv, poa, and new hoses it will be less expensive to fix what you have. The vacuum motors in the cowl and right kick panels are reproduced now, and are about $100. POA retrofit kit is less than $100, txv is $20, and compressor about $400, new hoses are easy since there is no crimping needed.
If you convert it to 134a freon, that will require a different condenser and crimped hoses. IMO the condenser supplied with the vintage air system is not very good. There are better higher efficiency units avaliable. That will add $200 + some easy fabrication, reusing the original condenser brackets. Add another $200 for hoses, fittings and the labor to crimp.
All my cars have a poa retrofit kit, except my elcamino. The elcamino is smokin cold. But the others are also, will get below 30 deg vent temp.

The car with vintage air has less air flow volume, it is also not as cold, compressor shuts off at 48 degrees. I have adjusted the location of the evap temp sensor to get it as cold as it is.
Factory air takes up a lot more room under hood and clutters stuff up. Factory air heater core, or evap core replacement is painful.
I prefer the factory controls, it makes sense, you can feel when you are moving a cable. You can feel the detents on the blower switch. Cables are not going to break or go out of calibration.
I like having a vent position, and fresh air when ac is on which the va system does not have. VA is always on recirculate, or "max air"

VA's evap and heater cores are much smaller than the factory, therefore taking up a lot less room.

Re: 1967 Camaro AC Question

The complete AC system is out of the car at the moment, so either way will be about the same work and probably money. I not interested in making modification that are permanent, as someone down the road may want to put the car back original.
