Be careful adding Freon by gauge pressures. Most air conditioning
service men pay more attention to the temperature drop and
temperature of the suction line and just look at the gauges for
reference. It is easy to add too much Freon and damage the
compressor.

Can anyone tell me what the low side and high side pressures should be on
one
of these 16k units? I have the R22, and the gauges but am not sure of the
pressures and how much to put in.

Also, be careful of the ambient temperature at the time Freon or its
replacement is added. Not good to do it on a 98F day.

Huh?

Ron, how hot would you guess it gets on a rooftop in the middle of the
summer when your dauntless HVAC tech heads up the ladder with a
30-pounder in tow??

I've been doing this work for 25 years, nobody ever told me I couldn't
charge systems when the ambient was in the 90's. Guess I learned
something new today.

Now, now, let's not get testy. I'm only a victim of my experience when a
professional HVAC tech overfilled my system on a very hot day and that
caused the compressor to "slug." Now you're going to tell me that's wrong
too. Well, I'm just a consumer and that's what happened to me. If the guy
was misleading me, I'd like to learn.

While we're at it, my 20 year old Cruisair normally can create a 15 degree
difference between inside and outside. As you know, North Carolina has had
record highs the last few days and the same for tomorrow. In fact, tomorrow
will be 102F. Right now at 2330 it is 82.2 outside and 74.7F inside. Given
that the boat's insulation is a constant, what is happening? I do not know
the temperature of the water, but I imagine that it is higher than normal.
The strainer and intake are oversize and feed two other pumps which are not
turned on.

Any ideas?

true... last year after regular service, i started having problems with one
of my units (16k Ocean breeze split). woudl pop the breaker whenever i'd
try to restart it unless it cooled off for a few hours... so it woudl start
fine in the evening, but i'd have to freeze my b... off till late in the
night knowing that if id' up the Tstat it woudln't restart...

the guy tried to push a new compressor... i got fed up and as a last resort
started lowering the pressure myself by pushing on the valve... After a few
attempts, i got it to to the point where it woudl have no problem
restarting on a normal thermastat cycle.
