But if the system is empty they are, by law, not allowed to regas it
without leak checking it first - generally they draw it down and
charge with nitrogen to leak test. Ultrasonic leak detector works just
as well with nitrogen as with "freon"
Friday June 6, 2014, I called to ask. I got a reply voice mail saying it
wasn't working all that well.
Saturday June 7, I went out and put the gages on.
The low side was six inches mercury below atmospheric.
This means the refrigerant leaked out, and it's a
high pressure side leak. I'm going to return monday
and put a little in. Close the service valves. Return
Wednesday to see if it's leaking from the indoor or
outdoor portion. Decide where to go from there.

So, I guess bottom line is the first service company wasn't scamming
and the system does have a real leak, somewhere. Didn't first company
tell the HO where the leak was, what all the problems were that lead
them to recommend a new system?

Well, I've done a fair bit of automotive A/C repair and testing and
I've had LOTS of evaporator leaks that sure didn't produce a zero psi
reading on the low side. Not even CLOSE to zero. If they did,
troubleshooting would be a BREEZE.
