How much is "1 pound" of freon ? I highly doubt it's enough to replenish a standard car like an Accord...

Any idea how much is needed if it's completely gone ?

They sell it in WalMart. Go check and see next time you are there.

The 3 minutes I spent in the auto isles turned up nothing... I guess I'll have to look again. But still wondering... exactly how much will "1 pound of freon" fill me up ?

About 2 lbs for an Accord (IIRC you have a 4th gen). Has it already been converted to R134?

good point... it's a '90 and it probably still on R-12(?)... but I just wanted to get an idea. Probably going to actually fill up the '95 Rodeo which should be R134a. If you know how many lbs for a Rodeo, that would greatly help when I hit Walmart later...
 
Look under the hood. There's a sticker somewhere that's easily accessible that will tell you what the system's capacity is and what type of refrigerant is in it. Also, you can look at the valves themeselves on the AC lines. If the have screw on caps they're R12 and I believe R134 has quick-connect type connectors. Not 100% sure on the latter.

Thought it was illegal and you had to go to Mexico to buy the stuff...

R12 is now illegal according to the howstuffworks.com link in the older A/C thread.
 
$40 is WELL below market value for R12. Most shops charge at least $60 a pound. Anyhow, R12 is illegal in the sense that you have to be licensed and trained to buy it and have proper equipment, etc. IIRC it is not produced for sale in the US either.

IIRC it cannot be legally sold, distributed, or bought without a license. I'm going to jail!


They do make R12 replacements (substitutes), but I don't know much about them....


Hmmmm....a collectible eh?
 
rh71, my cost on R12 is about $40 a pound in 30lb tanks. I sell it for $65 a pound when I service older cars. You really need to weigh the cost of the Freon verses converting it to the newer and less expensive R134a.

Plus R12 rarely just leaks out, it is very likely your system has a leak and will need repair.
 
in my old car, i had to pay $50/lb and my car took 1.5 lbs (it was an old '93 nissan nx)...i'd imagine your accord would probably take about 2lbs if it's completely gone.

Let me understand this... you're saying R12 (for the '90 Accord) doesn't leak out. But it can be "used up", no ?

Same question goes for R134a - "used up" vs. leaked out ? Mechanic said my 95 Rodeo (R134a) had a leak a few years back... but he replenished it and it was good for 3 summers... I was just planning to buy another 3 summers even with the leak..

Not sure what's going on with the R12 Accord though... it was good and strong for at least 3 years after we bought it used in 99. Could be a leak too... but again.. if it costs < $100 and can last a few summers, that'd be fine.

How long is A/C good for on a brand new car ?

It's good until the system develops a leak.

No, what I am saying is your system most likely has a leak and recharging it without fixing the leak is just a waste of money.

R134a is a different refrigerant. It is made with a small molecule and can seep out over time. Most systems are fine for 5-6 years, but after that you can lose refrigerant up to a pound a year. And with refrigerant loss come oil loss which if it?s not replace when recharging it can damage the compressor.

You're forgetting labor and the laws that prohibit a mechanic from charging a leaky system. Most likely the repair will run over $2-300.

On most cars I have seen it last over six years, some European cars have been over 12 years before needing service.
