So it got warm up here for about 4 days mid 70's i decide to check my A/c it's low a/c compressor constantly kicking on so Pump it out yes i used a vacuum pump
(father does commercial heating and air it holds a vacuum until u remove the gauge from the low port my valve in my low port leaks sob. so after i drained it all out pumped 24.oz of r-134a straight from the 35lb jug Blows Cold as hell now
what Pressure should my Low Side be reading tho? when it's running im getting anywhere from 35-40lbs when it's running. and when the compressor kicks on (very rarely now) it drops to 20
here's how i fixed my leaky valve tho haha that valve on top of the low port cost about 60 bucks lol dad had one laying around then the gauge is kinda cheaper it's not a liquid gauge he wouldnt let me have one of those.
sorry for the poor picture Damn Smart phones have 2mp cameras >.<
what psi should it be running?
