a/c not as cold as it should be

tylem28 · 06-23-2008, 10:29 AM

well my fiance pointed this out to me the other day that the a/c isnt near as cold as in her car (01 ford focus 32K miles) The jeep has a little over 104k and i was just wondering how do i check the freeon level or pressure and what type of freeon does the jeep take. Also is this normal for a 4 year old vehicle with a little over 100k? is there something else i should look into or look for?

Thanks

just go to advance or walmart (or where ever) and get a recharge kit for it. Hopefully it'll be simple as that.

well thats what im hoping but how much should i get i dont know how much it holds? also how do i check to see if thats the problem or if it needs any more refriderant

just grab a can of it. It has a gauge on it telling you how much pressure/refrigerant is in your a/c system. Follow the directions on the can.

Not all the cans have the guage on it, get one that has the gauge on it. Also be sure to get one that has the stop leak inside it.

Stop leak frequently does more harm than good. I would get the stuff without it.

ok fixed opinions from everyone. so what is the stop leak? im assuming its some type of additive that helps reduce the existing leaks in your lines.

Most recharge kits now contain lubricant, leak sealer and an o ring conditioner.

I used this stuff about 2 months ago on a completely dead AC system, and it's been working fine since:

I got it for about $21 and it comes with a presure gauge that you can re-use whenever you need to buy another can of the junk. If you search around on that website there's even a video or two to watch about how to use the product.

Overall, very simple and straight forward. It fixed my problem.

By "completely dead", I assume you mean that the compressor clutch wasn't pulling in (low pressure). You really should have checked the system for leaks before just recharging it, of you'll be doing it again soon. Refrigerant doesn't just disappear on it's own. If it had zero pressure, after finding and fixing the leak(s) and replacing the accumulator, you really need to pull a vacuum on the system before recharging. NEVER use a stop leak in a AC system.

I had my mechanic check it out. They evacuated and recharged it. It was running cold but they said they detected a leak in the evaporator and kindly handed me a bill for ~$1100. They evacuated the system before sending it home with me so I didn't have to pay for their charge so before I filled it myslef it was empty.

The stuff I used says it has "3 ozs. of Lubricant including Cleaner, Leak Sealer & O-Ring Conditioner" So far, so good. Blowing cold on hot days.
