Then just answer his question.
Here's the information:

Here's one for ya Stormy...

Bryant RTU... 588 model
Trouble reported... no cooling - frozen evap coil
After unit thaws out...

Filter clean, evap looks clean, blower is operational, cond looks clean...

CY: Looks clean... can be deceptive. I've worked on units that look fine,
but after cleaning coils, the performance is much different.

Readings as follows

IWB 68
SP 61 / 34

CY: For an R-22 unit, that's a good SP.

ST 92 / SH 58

CY: SH is a bit high. Makes me wonder, is it absorbing excess BTU, or
failing to release those BTU?

LP 295 / 129

CY: That could be h igh for LP, but then, it gets hot on roof tops. Lets
keep reading.

LT 122 / SC 7

CY: Presuming that's the LT coming off the bottom of the condensor. That's
rather warm, so lets see what air temps we have to work with.

AT104 CT 125 DT 21

CY: It would be nice if the LT was closer to the ambient AT. It is clear
that we are discharging some heat, as the condensor does have some DT.
Still, at this point I'm thinking the condensor coil need cleaning. Sure
sounds like the liquid line temp is a bit high.

CRLA 18.0
Actual 15.5 A

CY: So, the compressor is running slightly under current. This indicates
that it isn't moving the weight and volume of refrigerant that is designed
for the system.

What's your diagnosis?

CY: It's the thermostat. It's almost always the thermost. Needs a new
digital, programmable. And it has to be wired in with non metalic, electron
free wire. So, when you all stop laughing,snorting, snerking, and guffawing,
continue reading. From the information we have, the system appears to have
two problems, and there may be more problems than that. The high liquid line
temp indicates that the condensor needs cleaning. For me, that's the first
step. The liquid line should be closer to the ambient air temp. The high
super heat suggests one of several things. The RA ducts may be leaking, and
pumping attic air. Less of a concern in the case of a packaged roof top.
The suction line insulation may be missing or ineffective. (Less likely a
concern in a roof unit; I'd be thinking bad insulation in a residential
split). Or, the system may be gosh awful low on freon. If the only problem
was clogged condensor, I'd be expecting a warm evaporator. Considering the
frozen coil, I'd want to clean the condensor and then recheck the SH. Might
need to hook up the old jug and give her a rip of that good Freezon stuff.

Wow, where do we start?
This evap has a header with pistons and the AT is 104.
Do you still think that a SP of 68 would be normal???

How is the evaporator absorbing excessive btu's with a IWB of 68???
Failing to release btu's with a DT of 21 across the condenser???

Since this unit is fairly old I would bet the ducting is fine
Unit was manufactured without suction line insulation
What to guess again?

The morons thought process is, um, restricted, but don't tell him
that.

        My favorite was '58 SH is a BIT high'. Yeh, just a BIT :-)

It got a 'bit cold' here last night (12 F), but we decided to leave the
furnace off, till it really gets cold!!!

Doc said it didn't feel as cold to me, since I was running a fever and my
body temp was a 'bit high'. :-)
