ac problem

[t1nnockr]

i moved my ac unit to a different location. its a 1 1/2 ton.

i sucked it down, closed the valves. cut it out and moved it. after i brazed it back in, i leak tested and everything was good. so i put a vacuum on it. when i opened the valves again i got very little pressure on the low side and nothing on the high side.

anybody know what the problem could *

thanks for the reply. i did check all connections thats why im baffled by this problem. and the low side only went up to about 20 psi. it was working fine before i moved it.

i didnt have any nitrogen and i always take my shraders out before brazing. when i opened the valve i heard the gas go through. im thinking now i lost the charge so im gonna try to add some gas and see what happens

If you're going to fly blind without gauges then at least put in a sight glass so you don't ruin the compressor.
