Recharging cab AC unit
OK, maybe I should not have done this… based on the forum comments. Last year our MH cab AC was blowing air at 75 degrees, or maybe even warmer. Summer is here and it is doing that again. We are using it this week so I wanted cooler air than that. I bought a can of 134a leak sealer. I had the reusable dispenser from last time. I found the low side (a blue cap just like the dispenser connection) and connected the dispenser. I was careful not to turn the can upside down but did shake it… same as last time. The gauge on the dispenser measured about 10 psi or less before starting. I had already started putting in refrigerant/sealer before thinking to check this. I put the entire can in and the psi came up to about 20+ psi when the compressor was not running ( I am guessing on this) and would move up to about 37 psi when on. This cycle occurred maybe every 15 seconds… I did not time it. Anyway, the AC is now blowing air at about 68 degrees.
The gauge on the dispenser has an arrow to point to the outside temperature and then a range that the psi should be in when charged. I barely got it to the minimum psi when the can was empty. My question is if it needs another can of regular 134? I am assuming a leak and this might or might not fix it but we are leaving tomorrow and I do not have time to take it somewhere.
