R22 compressors

[rourkeh]

Does anyone know where to find new A/C compressors for R22 systems???

You will not have a hard time finding a R22 compressor.
Start with Grangers.com
Then some simple internet searches.

Assuming you're looking for a R22 compressor for a Cruisair A/C system. I just had a brand new 16 kW unit installed by local Chesapeake marine A/C repair service.

Should not be an issue locating one.

I did internet search and not much out there. Mostly ebay retailers. Graingers is a bust.
I was hoping someone here had purchased new R22 compressor for Cruisaire unit recently and could point me directly to the source.

I’ve bought a bunch of compressors from grainiers over the years but the last time they wouldn’t sell to me because I didn’t have a refrigeration license. Even though I told them I was buying it and having a licensed contractor installing it. R22 has become like gold and hard to get.

Other than industrial and large / custom equipment, R22/R417 compressors and parts are not made any more.
What small stuff (ours), that is on the shelves is it.

Supply & demand are driving the prices to painful attitudes.

Grainger and others, are saving the compressors for their commercial buyers.

In the meantime, R410 prices are pretty low.

I put in a new compressor several years ago. It came with a 410 tag on it(I think). I hooked it all up and the A/C tech vacuumed it down and charged it from my tank of R22. It has worked great. He said it was the same compressor with just a tag on it to use the new refrigerant.

I bought it from Steve Pooler (SPCoolin on this forum) just before he died. He told me what to do. I miss that guy.

I am down in the Caribbean and I can go to the local A/C shop and buy a 10lb bottle of R22 gas for
$150 but they non longer sell the compressors. If I switch to 410a I need to buy new dryer, expansion valve or capillary, and, then clean out the whole system with nitrogen before filling.
It will cost a lot more than just replacing the compressor.
Still looking.

I believe what Cheney is saying is that you can buy the R410 compressor and purge the R410a from the compressor and recharge with R22 and the compressor will work just fine on R22. That way you DO NOT have to change out all the other components.

I do know this is a viable solution as this was one of the options on mt recent compressor change out.

There is a drastic change in compressor oils.
There is a drastic change in compressor pressure levels.

There is nothing compatible between R410 and R22/417 equipment.
Maybe a fuse and blower motor.

Maybe it was labeled 417. I'm not sure, but it wasn't R22.

I bought two new direct expansion 16000 BTU units from Aqua Air in Florida. I called the factory, they built them and shipped the to me. They swapped out well, same foot print as the Lunair. It's been a few years but at that time they offered two Freon options. I wanted R-22 because I was only replacing the condensing units. If I remember correctly, the metering device in the evaporator was different depending on which option you choose. I had to run cat cable for the digital thermostats and remove the old Honeywell's. I have been extremely happy with them. Aqua had good customer service then. They sent me good manuals and answered a couple questions by phone.

I just checked Aqua Air's web page. It looks like they only offer units that use R-407C now. If you call they might build you a R-22 unit.

I found and purchased 4 new R22 compressors.
The only other option was to switch to 410a which requires changing the capillary, or expansion valve and other components. My biggest worry was that due to the nature of the split systems, and the long runs of copper tubing there was the potential for leaks. R410a operates at much higher head pressures than R22.High side pressures for R22 are around 225LB and R410a is over 400lbs.
My boat probably has original copper tubing and it is now 40 years old. Copper gets very brittle with age and a huge increase in operating pressures offers potential for line failures or leaks at the joints.

I also found out from talking to the guys at Flagship Marine in Florida during my search for compressors that R410a is about to be fazed out and no longer available due to new EPA regulations in the U.S. The only replacement available for A/C systems is a newer gas that is FLAMMABLE. Probably not a great idea for use in marine applications due to leaks. You would think that they would come up with a suitable and safe replacement gas before outlawing the old one.

Anyway I solved my A/C problem for now and will be going out tomorrow to the local A/C supply to buy a 20lb bottle of R22 gas that should last me a long time.

Other than ammonia, Propane was a great refrigerant.
People learned the hazard after a car wreck or two.

I have not heard of this new gas but I wonder if it is based on fossil fuel.

We can thank sleepy Joe Biden for passing the new regulation. The Man is a hazard.

R-22 was safe and suitable until some politician joined the Montreal Protocol. Getting rid of R-22 in the 90's was supposed to stop global warming. I guess it did it is going to be 20 degrees in Louisiana tonight.

I have replaced 2 compressors last year or so. They are compatible with the rest of the system (think dryers were replaced) and use the R-22 drop in replacement. Tomorrow I can get info off the compressors as well as the drop in replacement number. Will also check with my AC guy (he has gray hair so trusted source) to see if availability of anything has changed.

Here are the two compressors I put in around 2 years ago.

Hey Madhatter - I'm unable to read numbers off those pics - any chance you have a close up pic or the info directly?

Thanks in advance - Rob Maher
