My A/C is "cool" but not cold. I want it to be cold. I bought a recharger can, but the condenser is already "full." Is there a wayyy to purge the old refrigerant?

nope, you cannot use those cans at the store. our system is way over 100psi and you will mess something up trying to fill it. you gotta take it to authorized HONDA shop (prolly dealer only) and have them hook the machine up to both hi and lo pressure ports, then drain it completely, measure how much was removed, then add new oil and refrigerent. adding the wrong oil will destroy the compressor. youve been warned.

before you do anything, drive it at 65mph for 15 mins with the dial to max cold, ac on and recirc button on. if it still doesnt get cold enough, have it looked at. oh and change your cabin filters too. it blocks alot of airflow.

alright thanks for the advice. So are you saying that we can't use the auto parts stores ac recharge?

No you cannot, as gearbox stated the job is pretty much easy to botch if you dont have the right equipment(dealer).

alright, good thing i didnt use it
haha
i just took a reading from the gauge

ugh i guess Ill live through summer with sucky A/C.
id much rather spend the money in suspension and sound system upgrades.

hey, I live in los angeles and I dont have AC

I did use one of those kits what am I looking at in terms of damage?

 
Rep Power: 811

well i really dont think its even possible to put any refrigerent in with that high of pressure. it prolly all just vented out around the hole.

well something went in because my ac works now

I charged mine with a couple of cans of 134 and got it to blow cold enough for me. I did suck it down with a vacum pump for 5 hours before I put any in. I should add that now I have no a/c at all. My clutch flew off the compressor while i was driving down the road. Prob had nothing to do with me charging it but stranger things have happened.

did you add the right kind of oil after you drained the system? its very possible you seized the compressor either using wrong oil or none at all.

I used a can last summer, or part of a can. The stuff went it, because my stuff got colder, but its right back to the crappy state it was in before, it does get cold, but not cold enough. I'm thinking it has something to do with..... i have no idea. lol

I used the can of 134A with oil. A/C worked fine for a few weeks then I started it up one morning and it was not getting cold. Turned a/c off and drove a few miles. Pushed the button to see if it would work and a few seconds later there was a noticeable clunk and the clutch was rolling down the road. All the teeth on the inside of the shaft hole on the clutch were ground off, but the shaft on the compressor looks fine. Now I'm debating clutch kit vs new comp.

but if it really was that dangerous, wouldnt there be a warning on the can or in the owners manual or something? maybe the danger just lies in overpressurizing. and wtf is with the gauge telling me my A/c is at 45psi if the tank holds well over 100psi?
and triz
if it the tank holds over 100psi, you probably added sayy a few psi (maybe 20) on the top of the compressor. So this stuff was very cold for a short while, when all the new stuff was pure. but then it probably got mixed in with all the rest of the 100psi particles, therefore diminishing its effectiveness.
My theory anyway.

From what I understand, it's not so much dangerous as ineffective in high-pressure systems, such as ours.

Just for reference, here's how the system works, on very general terms:



With increased pressure, the temperature drops dramatically since volume is constant (closed system). Application of the ideal gas law. The inverse is true of turbos, because volume is never limited by the environment.

yup, and on the back of a can is a warning that says if the pressure gauge reads in the yellow or red, take it to a shop lol.

yea I saw that, but when I hooked the gauge up it read 45psi, which was in the "good" range. albeit on the tail end of it.

very informatvie unevolved! Your definetly one of the more helpful people on this site, and Id rep you if possible.
