DuraCool at home
- Thread starter richard
- Start date
Home air conditioning systems used R22 instead of R12.
You can buy a Duracool replacement (HC22a) for house air conditioners.
They are not designed for R12 or R12 Duracool.

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.

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.

No, it is not illegal. Stationary systems such as produce and meat coolers, freezers and buildings are legal. Hydrocarbon based refrigerants are commonly used for those applications.
If it doesn't have wheels it's legal.

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.

It IS illegal in RESIDENTIAL HVAC systems, as I stated.
Not illegal in industrial or retail refrigeration systems.

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.

I wonder which of the 3 AC guys backed it off so they could top you up every year :lol:

In all my years as a commercial A/C mechanic I never considered causing a leak for future work as I was always busy fixing stuff that needed my help.
Customers don't like it when they have too keep having the same problem raise its ugly head.

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.
