Well, my 88 STD never came with A/C, and I got rid of most of my A/C parts that I had taken off my CRXs.

Anyways, I'm thinking about fitting in a small window A/C unit(where the rear seats usually are) and just using inverter or swap in a 12V DC motor and just get rid of the controls. Of course, a larger alternator will have to go in or an auxiliary battery(not sure about the power consumption yet, but I'm looking at a 6000-6500BTU unit).

Only think I can't think of right now is the ducting. The condenser will have to be in-car because I don't know if there's connectors that will keep the freon from leaking when taking the unit out or putting it in. Although, a permanently externally-mounted condenser would work better; I'm thinking of just using ducts hooked up from the rear windows, using foam insulation boards to create the mount so to say. Only issue is; I was thinking of one side is exhaust air, and the other is inlet. How the rear windows open up; would this make it difficult for the unit to pull in air? What about air behind the hatch? I don't mind cutting up the hatch because that's easy to replace.

Really, adding a roof scoop would be ideal...but I do not want to do this. If possible, no cutting up of the car at all(at least nothing that's difficult to seal up or replace).

I'll draw up a picture of what I'm trying to do.

I attached a quick sketch(sorry it's crappy).

Anyways; there will be a board bolted to where the back seats are bolted. The A/C will mount to the board. Also, half of the (a/c air out) ducts will be ducted to the car's HVAC system(tube going under passenger seat)...so you have cold air blowing in front and behind you.

Or just go to a pull-a-part and get all the stuff Honda made for your car and put it in with a new orafice tube and r134a reterofit kit ;)

When it's humid, a fan just blows hot air into your face. On those days I just crack my window open and wear a sweat-band.

Why convert to R134A when I could just use Freeze-12? :) I don't want anything permanent since the nights here are cool. If anything it'll only be in the car when going to work or trips. Plus, It'll be a hassle to put A/C in; mainly because the central HVAC box/heat exchanger has to be taken out and the fittings are always stubborn when trying to remove them.

Why not do it? It's not permanent at all.


I should be picking up the window unit Tuesday morning, so until then I'll probably just be measuring everything and getting the "platform" set up.

I just quick searched Home Depot's website for a 6500 btu unit, and it takes 6.1A at 120V. That's 61 amps at 12V.

I believe the stock civic alternator is in the neighborhood of what, 40A?

That air conditioner consumes 0.981 hp to operate and is sized to cool approximately 1500 cubic feet in a room.

True it wouldn't have to run very much at all, so the car could recharge the system when it's off. It shouldn't completely kill the electrical system if you had a [few] batteries to back up the electrical drain on start up but the alternator might not like running 100% that much.

The exact unit I'm looking at is rated like 570-580W; it's a Sharp unit. Even then, I'll still have an auxiliary battery for it.

IIRC, the stock alternators are actually rated 70A. I'm still going to upgrade the alternator to at least a 130A unit though.

With no back seats in the CRX and just that security compartment, you can probably make it look very clean.

Yup you're right. Still a good idea to upgrade. Good luck, I wanna see how this turns out! Redneck engineering FTW!

I see what your doing. It might be cool, but Im thinking not. Go to a junk yard, buy some PB Blaster, put oem a/c in. Its NOT that heavy.
