i recomend you get an ac book at the library and study hvac
before you work on it. ac systems are very simple but you need to have
knowledge how they work , and service procedures. lucas
Not to mention the equipment which virtually no homeowner has...
-------------------------------- when my
cousin retired from doing ac work, i found the ac companies allways
wanted to replace the units rather than fix them, so i bought my own ac
equipment and do it myself , the equipment isnt very expensive at all.

Hmmmmm: All portable Units (AC) are Hermeticaly seal, adding gas is not seple as
it may sound.One way is to open system add line tap and add the gas= not so
good, one must know howmuch to add. Two remove all refrigerant and add OEM
recommended amount not so good either, Best way buy new unit!!!!

Curious, did this pro give a reason that it can't be replaced? I thought
it could be, it's just that it's not worth it because of the cost. And
the cost is driven by the fact that if the refrigerant is gone, then it's
leaking so it's likely that something, eg the evaporator is shot, so
more than just recharging it is needed.

It may be just an hour, but what do you charge for an hour of time? That
plus the cost for the fittings, refrigerant? That alone makes it impractic
when you can buy a 5K to 8K BTU new one for $120 to $150.
While not a lot is involved, it is impractical price wise.
First you have to install the valves to recharge it . That requires
breking the line. Not sure how you would recover the refrigerent left
in the system,but that is required by law. Put a vacuum on the system
and recharge it. Find the leak which may or may not be easy to get to
and repair. After finding the leak, recover the refrigerent and repair
the leak. If the line is aluminum, it may be difficult. Pull the
vacuum and recharge the system and retest.
I doubt that could be done in an hour. I have no idea what a standard
repair charge is per hour for labor. If it is anywhere like what I was
charged when the man came out and just spent 10 minuits replacing a
motor capacitior on my heat pump ( about $ 300), you could buy 3 or 4
I doubt the repair man would even repair his own dehumidifier if he had
any work at all to do.

If you make up your mind this is a throw away anyhow you could just
buy a piercing valve and shoot in some R134 (walmart car area). It
might not be the right refrigerant and it might not last long but if
it blows cold air until you get around to buying a new one it might
work for you. Squirt in a little, wait a few minutes, try it, repeat
until it is blowing cold air. Too much is as bad as not enough. A
whole can is probably too much unless it is totally empty.
I did that with an old fridge and it lasted until I moved to Florida
(a few years). For all I know it may still be working but I really

With 134 it's likely only about 4 ounces - or a quarter can. I did
an old fridge years ago with the pierce valve and R22 - topped it up
about 4 times from one can of refrigerant over a period of mabee 2
years - then scrapped it.
A new AC can be $129 and up.
Do you have the fittings needed on hand? You are going to nitrogen
braze them right? If you are doing this in an hour you are not doing a
very good job on vacuum.
Do do it right, what is a fair price?

WTF? Nobody here can read? Let me help you with the second sentence of what
"What may make it impractical is finding and repairing
whatever leak released the refrigerant in the first place."
There is also the matter of not sending more crap to a landfill...
