Arrived at job. Lady said, there was a water leak in the bsmt. This renovation comp. came, dug-out and installed new wheeping tiles. While doing that, they disconected the A/C and moved it. Re-connected it after they finished.
A/C, of course, was not working immediately thereafter.
So, I put my gauges, and what do I see. S.L. 25psig, L.L. 500 psig (it took only 3-4 seconds to reach 500 psig). Luckily I was fast enough to pull the plug on the 240 V disconnect box. This is Concord 2 ton installed in 2000.
Oh, I forgot, this renov. comp. actually burried both coper pipes underground.
Compressor was drawing 9 AMPS (plate says 10.2 AMPS).
Apparently there is a restriction - the question is where is that ?
Full of air probably. A restriction would just condense the refrigerant in the outdoor coil and your head wouldn't skyrocket.
BaldLoonie "...Full of air probably...."
Well, that's what I though first, but then I decided if the system is full of air - would not the S.L. reading be HIGH too ?
It is only 25 psig on the S.L.
I'll take both lines kinked/crushed under the slab for $200 Alex.
and i will take
" How does air get into a sealed system " for $100
There is you answer a big old restriction, they should have called an a/c company to take a/c loose and reinstall, when did renovation company's start taking on the liability of removing a/c units?
