Okay, YES I know to do it right Id need a set of gauges for High and Low pressure butttttttttt all I have is one of those cheap 134A can type filler gauges between the 12 oz can and the low pressure suction fill side.
Soooooo the Chevy RV has a slow freon leak and needs charged maybe once a year. A while back it began short cycling the compressor with not too cold air and finally it got so low it quit even cycling. Sooooooooooo I toss in one 12 oz can and it starts short cycling maybe cooling just a bit Sooooooooo then I add another 12 oz and it starts to get pretty cold buttttttttttttttt at idle it still cycles somewhat albeit she pumps a fairly long time and is blowing cold air. The cheapie low suction side gauge shows good/safe green 25 to 55 and when shes pumping it drops to around 35 and when she cycles off it rises to maybe 40 to 45.
QUESTION 1 Think it needs one more 12 oz can???? Cuz why does it still cycle (but runs fairly long and air is cold) at idle????
QUESTION 2 Using those 12 oz cans will she not take anymore then she needs??? i.e. if another 12 oz can is too much will it simply not take it all???? I KNOW TO STOP IF SHE GOES OUT OF THE SAFE GREEN 55 AND STARTS INTO THE RED HIGH DANGER ZONE but with the 2 cans I added shes still safely in the green so far.
Thanks in advance, its hotter n a hammered "Hill" and were takin the RV to Evansville and Louisville to see the sons band play the next couple nights AND I WANT IT COOL WHILE DRIVING.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
