If it is pretty low - it has a leak......biggest problem is finding the leak. look for oil around all of the joints or maybe even coming from a pinhole on one of the lines. Used to be able to recharge using the gauges (ambient temp + certain amt was one of many formulae going around) - but now, I hear that it is best to pump it out - hold a vacuum for a couple of hours (maybe even overnight to be sure that there are no leaks) then replace freon by weight. I do a/c so infrequently that I have to sit down with a book & relearn it every time. -- Carlo F.

Weight replacement is recommended for R134a. I presume that older systems with R12 are OK to recharge by gauges, but the weight method will still be more accurate. There should be a sticker under the hood which states the total refrigerant capacity. AC Source has an R12 Recover/Recycle system that can be converted to R134a and (they say) is within the price range of the DIY mechanic. http://www.acsource.com/product.asp?3=204 I am tempted to buy it, because I have two air conditioned vehicles and it is a 150 mile round trip to get an AC technician to look at one. I finally found a good one in my area after about four years living here. Unfortunately, everyone else in four counties knows about him already. A poor AC technician can burn up your money in labor, parts, and refrigerant pretty fast... Ditto on the leaks. A good place to start is to get an O-ring assortment that is compatible with your system and replace all the O-rings at once. This of course assumes that you have some way to remove the refrigerant from the system and evacuate it before refilling. Earle |

I don't know how hot it gets in your area of Colorado, but here in Vista, California the summers have been getting colder and colder. My Bronco and it's R-12 gave up year before last and I haven't needed it, the 2/70 A/C works just find.

Come to Grand Junction in August. Sometimes it is even humid! My Suburban is borderline after the R134a conversion the previous owner had done, even with the rear air conditioning. Earle "L.W.

Grand Junction is sorta unique, being an honorary part of Utah. And housing subdivisions built on uranium tailings that don't need streetlights, just let the backyard glow. And really not as much fun place to gas up since Gay Johnson closed their restaurant. Earle Horton wrote: Come to Grand Junction in August. Sometimes it is even humid!
