Emery (and everyone),
Can you comment on experience using DuraCool in a standard home HVAC system?
Mine is maybe 6 years old with R22 in it.
I put it in my Palm Beach years ago and have been very happy.
Thx

Bukzin,
Most home units are R-22. There is an HC replacement, but it is not DuraCool and I don't remember what it is.
The thing to remember is that the halogenated hydrocarbons (R-11,12,22,502etc) were created to get away from the nasty things like NH3 (toxic) and CO2 (high pressures), but at the time, propane (part of duracool) was already being used as a refrigerant, but there was not way to patent it.
I have experience with all the "environmental disaster" refrigerants, but am too old to have been really dragged into the new versions.

If I recall you can upgrade an old system first to R134 then to DuraCool for RV's etc.
Would that also apply to a home system?

Emery,
Would I get them same improvements in cooling and reduced power consumption
as I did in my GMC?
Do you have a link to those products?

The only thing wrong with charging a residential HVAC system with the HC-based substitutes is that it is illegal. Not for any sound scientific or technical reason, just that the lobbyists for the CFC patent holders scared your legislators into passing laws against it.
Scroll down on page http://www.duracool.com/ecom/shoppingcart.html and you will find:
In the United States it is illegal to use a hydrocarbon refrigerant as a substitute for a Class I or Class II ODS refrigerant for any end use other than industrial process refrigeration systems, or retail food refrigerators and freezers (stand-alone units only). See 69 Fed. Reg. 11946, 11952 (March 12, 2004), and 76 Fed. Reg. 78832 (December 20, 2011). Under the SNAP regulations at 40 C.F.R § 82.172, "use" is defined as "any use of a substitute for a class I or Class II ozone-depleting compound, including but not limited to use in a manufacturing process or product, in consumption by the end-user, or in intermediate uses, such as formulation or packaging for other subsequent uses."

Some HVAC Vendors like Goodman have approved R-422 as a replacement for R-22
It’s not that R-22 is not available (it is - at $825 per jug… that’s $225 for the refrigerant and $600 for the UN)
We used Duracool R-290 for a while, and then moved to R-424 (also marketed as “Acme Cool 77”. They were good, but voided the compressor warranties (generally 10 years), and required evacuating and nitrogen purging the system before charging. We calculated for a 20% loss in cooling capacity.
The R-422 seems to work at 100% in an R-22 system. I still have to purge the system before charging, but otherwise it’s a drop in replacement (no change in lubricants). $225 per jug, too!
It also makes my trips to London, Ontario purely personal (visiting a friend sons), and I don’t have to pick up the jugs of R-290.

Bigger question is where is your R22 going in a copper system with hermetic compressor. Unless you find and repair the issue it will continue to leak. Besides bad solder joints it can be as simple as tightening a nut at a joint to the evaporator. After 3 AC guys I simply tigtened the nut on the tube before the expansion valve about 1/8 turn at my old house. No more annual top off required.

Amen, Roy.
Most service companies are honorable members of the community. Competency varies. But decent folks.

Yea Right!
My house AC quit. I called a friend who sent out a well known AC company he worked with to repair it. The company declared the outside unit (compressor/condenser) not salvageable and needed to be replaced. They would call me with a repair estimate.
I went out and found the 24 volt wire from the house to the unit open and repaired it. That not salvageable until has been running now for at least 20 years.

Had a similar issue at my daughter's. She was told she had to replace the entire system as R-22 systems are no longer sold. I went over there and replaced the motor start capacitor and it has run fine for several years.

I know where you’re coming from, Ken, but those look like competency issues to me.

that kind of bad behavior is more likely to happen with small independent shops then larger Union shops that service mostly larger companies that are regular customers. If I were to tell Bank of America or K Mart they needed to replace a very expensive system because I wanted to sell them a new system rather then fix the old one with out just cause I would have been likely terminated. On the other hand small home owner repairs are mostly dependent on the honesty of the independent co and its employees unfortunately bad things do happen . There is no way that I would have been happy with myself telling some little gal she needed to spend big bucks for a new system when a new condenser fan and capacitor would have fixed the unit. Like bad auto shops exist so do other service co. Hopefully they don't stay in business long.

I (who started this thread) do not have any leaks on the system in question. Seems to be working fine but costs for power are very high
in this part of the world.
Just looking at getting more efficiency and lower current draw.
