I've heard some window units are being sold that use R-32. I haven't dealt with any myself.  We are being told to expect R-32 and R454b split systems to be the new thing in 2025.

Hi @ChrisJ , It's my fault. I sidetracked us by responding only to Ed's comment about having a body 30 years older than he used to have. Back to R values!

Yours, Larry

Anyone seen or used any units with this refrigerant? I just bought a new through the wall AC for our condo. I would have preferred a GE which I think the wall sleeves are originally GE wall sleeves, but the GEs are "out of stock"

So, I bought a Friedrich "Uni Fit" which means it will probably not fit anything LOL. Actually, it is supposed to fit most of the common wall sleeves.

Unfortunately, I tweaked my back. I wanted to measure the depth of the wall sleeve to make sure whatever I bought would fit. The bottom of the wall sleeve sits about 6' off the floor so standing on a 4' step ladder I yanked the old unit out (75 lbs) and set it on the top of the ladder while I measured the sleeve. Then I put it back in for now as the old unit still works and I was waiting for the new one.

My back was fine at the time but the next day I could hardly get out of bed. I have pulled these units in and out myself for years without issue.

I guess at almost 70 I have to stop thinking I am 40

I'm at a complete loss..... How does refrigerant relate to 1960s cars / hot rods?

. Hey Chris, I did an edit to explain the reference to the numbers on refrigerants numbers and 1960 hot rod numbers. Both sets of numbers need to have inside information on what those numbers actually mean. My sister would be clueless on what any of the refrig. or motor head numbers mean. But they all make sense to the trade that uses them. Look above at the edit

Here is another reference to unrelated topics:
The unitary products manufacturers have found the goose that lays the golden egg.

I remember gasoline at 24 cents a gallon. Then the 1970s happened, the price of fuel skyrocketed over 80 cents a gallon. The politician's step in to save the day and the price settled around 50 cents a gallon. The American people were satisfied to pay double the previous price. A few years later another oil crisis and fuel shot up over $1.50 per gallon, the politicians stepped in again to save the day and we were satisfied to pay about a dollar a gallon. This trend has made fuel cost over $4.00 per gallon and brought it back to $3.00 per gallon just recently. And we are going to live with the new higher price.

Anytime the fuel suppliers need to raise the price, just blame some geopolitical crisis and let the cost go way over what you really want, then drop it back to where they want it to be. Then America will be satisfied that someone reels in "Big Oil". But the price ends up higher each time.

About 25+ years ago the end of R-22 was in sight. The normal practice of installing an indoor coil or air handler and having up to 4 outdoor units connected to it over the lifetime of the furnace or air handler, came to an end. Can’t mix R-410a outdoor units with a R-22 indoor coil. Must replace the complete matched system. Now that those original R-410a units are getting to be 20+ years old, Those outdoor units might be replaced with another R410a unit. You can connect them to the existing indoor coil. But we can't have that… We must develop a newer, better refrigerant, so that you can't just swap out the condenser. We need to sell matched systems. More larger ticket parts. Make sure it is not compatible with anything they already have. This is a guarantee that every new condenser must have a matching indoor unit.

That is the golden egg. Planned refrigerant obsolescence!

@EdTheHeaterMan Sorry, I know what everything in the song means, but still do not see any relation to the thread.

Perhaps it's just over my head.

Have you ever known anyone that does not know what everything in the songs mean?
Or do only associate with motor heads?

Have you ever known anybody that does not understand thermodynamics, Hydronics and Refrigeration jargon? Or do you only associate with persons in our industry?

This attempt as sarcastic comedy relief however, is not all about you. As a matter of fact the joke was for everyone else except you. But it is nice that you shared your question about associating different aspects of the world with other aspects of the world and how they can not possibly have a correlation. We like when you chime in on this forum. Sometimes your opinions and information are actually helpful.

Thanks for pointing out that motor head jargon and trade jargon has nothing to do with each other. Unless you just look at the fact that it is jargon ...and all I said was that one jargon reminds me of the other jargon

Thanks for sharing

Edit: BTW, Betty Davis has nothing to do with cars or refrigerant, but it was a little funny.
