In the R-12 run up, the price went up for a few years.
Eventually, the replacement blends come out on the market.
And then the equipment starts to die off. As the equipment
dies off, the demand goes down, and that affects the market
and pricing. There is still R-12 equipment out there. I
know, I service them.
The latest word I have on R22 is that this year only 20% of what we
normally use will be available. The large producing companies are
indicating that the price will skyrocket and that it would be a good
idea to purchase large quantities in advance. I suspect the companies
are trying to create a shortage to drive prices up. Also it turns out
that R134A is being scheduled for a phaseout in the future also. R410
and a few others are also to be replaced. It was stated that Carrier
already has a replacement in their research facility. The socalled
replacements will consist of HFO's and CO2. This information is merely
being repeated and the source is a Johnstone Supply Training person.

134 was always going to be an interim refrigerant long before Obama
came along because its a greenhouse gas. The Europeans are phasing
out its use in autos beginning next year and banning it all together
by 2017. Its old news. They wont be happy til were back to using
I recover every ounce of refrigerant I can. If it's not contaminated,
I'm going to reuse it. Somewhere I have a 124 lb R22 recovery cylinder.
I take a little whiff and if it doesn't burn the hair out of my nose,
a good set of filters and some Acid Away makes it usable.
Why don't you just plastic bag it and sell it to your neighbors kids?
The world has a scarcity of whoofers. If they whoof it, it won't damage
the ozone and everybody wins. Won't have to buy carbon certs for it either.
I think they're called "huffers" and most of them get off on "toluene"
which is in the paint that they huff. When the refrigerant in a system
gets burned, it takes on a horrible searing odor that is what was used
during WWI as a chemical weapon, phosgene gas, better known as mustard
gas. If you start brazing connections on a refrigeration system that has
not had the refrigerant completely removed, you will get a very
unpleasant whiff of phosgene gas. Some people get off on huffing Freon
but it can be very deadly. The HVAC supply housed have been selling
special locking caps for refrigerant service valves that may help stop
people from easily getting refrigerant from outdoor equipment.
Your customer will balk at the price of Schrader locks. As for the
problem of internal contamination in the system from brazing, will that
is why the manufacturers and professional practices require nitrogen
purging. The oxygen deprivation from inhaling a cloud of cooling gases
has long been a problem. But whoofers cherish the synaptic cross firing
created by dying oxygen deprived braincells. One of the most dangerous
of these gases is R410, as it hangs on the ground and legislation is
being enacted to insure all equipment rooms using this gas has an alarm
system and automatic venting. As for the huffers... I will leave that to
others. I deeply suspect something of that nature is infecting the
political atmosphere in Washington DC.
Geez! Who can keep up with the sub-nomenclature that describes all the
different addictive behaviors of those who are trying new and creative
ways to kill themselves. Years ago, I worked with a guy installing the
control and power systems for the first indoor cooling tower in this
area. We also did the same for the screw compressors and one of the
things I installed was a stationary refrigerant leak detection system.
I believe R22 was the refrigerant being used. Enough of that stuff can
displace the air in a room and send one to HVAC heaven. Where does an
AC tech go when he dies if he is an evil man? Hmmmm, I'll have to think
about that one.
Yeah, that's a factor I've been hearing, the efficiency is supposed to
be a lot better on newer units.Of course, due to minimal usage, I've
never had a power bill over about $130. That's in the dead of summer.
Never running it, the bill's around $70. So at most it's costing me
around $2/day to run.
The other consideration is this tax break that's currently available,
and a modest credit from the power company.
Why tell me? The folks I do work for don't have the money to replace
a system. BeeHO hasn't stimulated theirs or my bank account so folks
call on me to repair what they have. It's called survival and making
do with what you got. I had an old fellow call me one day to look at
a Carrier he had bought back in the early 70's. It was the best and most
expensive unit Carrier made for homes at that time. It has stainless
steel hardware, factory sight glass, high and low pressure controls,
anti short cycle timer and a temperature controlled two speed condenser
fan. The condenser fan motor burned out and an HVAC company told him
he needed a new system. I took a look at his old Rolls Royce of an AC
and told him "Don't you dare get rid of this system!". I replaced the
two speed condenser fan motor and the system goes into low speed mode
at night and thanks to an insulating blanket over the compressor, it
barely makes a sound in quiet mode. His neighbors all around him have
newer AC units that sound like airplanes taking off. The repair bill
was quite a bit less than the $8,000 the other guys wanted.
And, that's the state of the economy. We're headed into a
depression to make 1929 look like party week at the frat
house. I get plenty of chances to rescue older equipment. I
regularly work on R-12 equipment that dates back to before
the freon boondoggle.
One thing you can do is take a clamp ammeter around the 220 line and measure the
On mine I measure 6 amps, which probably shows some loss of refridgerent
but its still working. older AC will draw a lot more amps.
