Fixing Central Air Conditioner Unit With R290 Refrigerant

Just a Random Video , Fixing the AC unit from 1990 With R290 "refrigerant grade propane"
Thought i would give this a try before i pull her out and replace it!
IT had been 2 months now and still working GREAT!

Don't delay, Hank Hill your AC today!

[@kevinroberts781]

R290 is what every ac should be using today. Heating and cooling industry is a cheap joke.

[@w8what575]

That’s no shit! Imagine how angry I was when I found out what r22 is after we brazed the line without knowing if there was any Freon in the damned line! And then! When I found out that r290 is propane! I spent $240 on 4lbs of r22 last year….and fixed my ac myself! Because hvac guys think they’re too good to work on old machines or even sell a new one to someone who doesn’t own a brand new home! Discrimination if I’ve ever seen it!

[@MAINTMAN73]

The pressures listed on the label are system test pressures. With refrigerant flooding back to the compressor this is creating a situation where the incoming refrigerant can wash the lubrication right out of the bearings, and diffuse into the oil. It is best to charging unit by superheat or subcooling depending on what your metering devices.

[@starpuss]

System is still working Since this video so "right now" I am not worried about it. But i agree When she dies again ill look into this again.

[@Mexmade]

Im glad you didn’t follow those pressures on the label 😂 fuck that would have been interesting.

[@thedavesofourlives1]

Equivalent charge to R12/R22 OZ listed on the unit is about half. Ice on your big suction line to me is a sign of being over charged. You'll be flushing the oil out of your compressor leading to premature failure.

[@photocontrol]

Great that the AC recharge is holding up! The R290 seems like it cools pretty good. Too bad that your outdoor weather sensor got damaged, cool looking thunderstorm formation!

[@starpuss]

Seems to be working good! Still a little TLC i need to get done on the system

[@photocontrol]

This is the good stuff, EPA approved lol.

[@photocontrol]

That's good! Yeah the system evaporator and condenser coils may need some cleaning etc. Looks like your weather station is a LaCrosse, I wonder if these anemometer cups in the link would replace the broken ones on yours. www.ebay.ca/itm/WCTX144W-La-Crosse-Technology-Replacement-Wind-Cup-Assembly-Only-for-TX141W-/273095394403?_trksid=p2385738.m4383.l4275.c10

[@solexxx8588]

@@skyewrighter3493 R290 is a drop in replacement for R22. You use less R290 and the suction and discharge pressures are lower.

[@Shaker626]

R290 is a more efficient refrigerant than R22, a third of the mass flow is required.

[@christopherleubner6633]

Frosting on your compressor means either your high side is plugged or it needs more gas.

[@starpuss]

The AC Unit has been working GREAT After i did this. And Still Working GREAT this year. But... I think after this video i did toss in a little more ,seeing i had another can.

[@thedavesofourlives1]

OR you're flooding the compressor!!!! Overcharged!

[@SuperChiliwillie]

How was the electric bill after the change? I heard is uses 30% less energy because it is way lighter than R22 and the compressor does not work as hard. Very curious is it made an impact on the electric bill.

[@starpuss]

I have not noticed any difference

[@averyalexander2303]

From the studies I have seen, I doubt that R290 would be more efficient than the R22 the system was designed for. At best, it might match R22's efficiency. If the system was redesigned to use R290 it may be more efficient, but using a refrigerant the system wasn't designed for is never going to be ideal.

[@thedavesofourlives1]

and a coo-responding drop in system capacity, but slightly more efficient if not over charged.

[@gregh7457]

You're not going to see much of a difference because that old a/c runs that huge fan at one speed, full, all the time. I think where you would see more of a difference is in a split mini that has an inverter

[@inoahguy1578]

I run about 60 to 70 psi low side pressures on r290

[@10rninjariderzx]

What was your superheat?

[@whaleoilbeefhooked3892]

So many unrelated distractions couldn't get past 3 mins...sorry.

[@DriveShaftDrew]

yup lots to do before the snow flys

[@UltraHydrophobiccoat]

A leaking system with gas furnace Will be a disaster in winter time if you use R290

[@starpuss]

Why Just Extra Heat LOL!!!! System is still working Great! NO Leaks "Yet" And my Furnace is not gas.

[@sparc5]

@Steve L the refrigerant runs inside too. It's a good post-apocolyptic fix, needs a smaller piston likely, along with an automatic vent and leak sensor to be safe. But seriously, good to know this can work in an old R22 system to keep us cool when heat stroke is the alternative.

[@fazerainbow5674]

that ac is old still works good hows the old frige lol the storm is something and the other the storm the way the sky look is crazy u should try storm quading lol i bin on a atv run and got caught in storms like that look like u got lots of future projects and plans to do takeing one step at a time so much stuff and so little time i about doing the same so much stuff so little time

[@starpuss]

The Fridge is shot lol! IT is working at 50% at most , I should have used a little R290 in her lol!! Storms like that are the best time to go Quading!! (We did that night lol!!)

[@fazerainbow5674]

i done that a few times lol sometimes it hurts the eyes it feels like knifes pokeing at your eye lol depending at what speed u r at also

[@fazerainbow5674]

also my nana had a propane stove lasted her 33 yrs just recently stop working

[@fazerainbow5674]

what kind of issue do u normaly have with the ac besides filling it up just leaks

[@fazerainbow5674]

anyways great video curtis looking forward to more i cant wait for more videos on the motorhome dune buggy sportszman house proxey and alll your other projects i was talking to your dad and asked with if u guys were takeing the motor home this year he said u had to clean it up for him tune up for him get cleaning finsish your chores curtis lol wasnt trying to be rude just a freindly joke and how is prioxey with her eating she seems to be doing ok better than most days and i saw proxey trying to go out in the rain u should of had her out there for her shower one lest job to worry about lol

[@19voodoo69]

Not for use in Home air conditioning..

[@w8what575]

Why?

[@shaung638]

Do you lose any cooling capacity?

[@starpuss]

Not at all , But... At the same time... when i got the house the AC i bet was not working at 100% LOL

[@22ndmeu1]

OMG !

[@10rninjariderzx]

Checking pressures? Lmao. Ever heard of superheat and subcool?

[@onemischiefmaker7032]

wow I can say I have now seen it.. just remember folks you can learn a lot from a dummy!

[@w8what575]

What’s so dummy about it? That he knows what the scam is with hvac? 🤣 r290 is propane! And worth $5/lb compared to the methane version r22 at $130/lb scam! Scam scam! Hvac is a freaking scam

[@bskull3232]

So, mixed refrigerant, no reclaiming on old R12, and indoor AHU not fire proof? FFS you are dumping propane to your system and you didn't get a certified indoor unit for that? A few pounds of propane, if diffused throughout your house and mixed perfectly with air, can level your house to ground!

[@starpuss]

Would have to be a huge leak that leaks out completely in less then a hour to be dangerous in my setup

[@ANATURALDREWSASTER]

What about the millions of natural gas lines, and homes with 200 gallon propane tanks plumbed into them? The only hazard here in my mind would be a technician unaware of a flammable refrigerant being present.

[@bskull3232]

@@ANATURALDREWSASTER Except your R22 AC is not certified to propane level, and you don't put your 200 gallon propane tanks indoors.

[@ANATURALDREWSASTER]

@@bskull3232 my point was that it is plumbed indoors, and that's far more likely to cause a problem than the ac charge.

[@grabir01]

8-16 ozs of propane is not going to level a home.. Please!!! 160lbs maybe . A small home. Natural gas turned on for an hour or 2 full blast might level your home. But that would be way more than a few hundred pounds.

[@epluribusunum5405]

Canadian no doubt, hey. Lol. Don't try this at home.

[@solexxx8588]

It's legal and available here snowflake.

[@gregh7457]

i tried it at home and it works!

[@w8what575]

I keep seeing these comments…lol…why? Please elaborate? U work Hvac huh? 🤣 cats out of the bag dude! R290 is propane! R22 is methane with a bit of flour one and chlorine and I think butane….and is absolutely not worth $120/lb! It’s bs…what’s gonna happen when they ban the other “ozone depleting refrigerant” co2? They gonna send u to the scrap yard? Or what about ammonia which is also said to be depleting the ozone layer ? All lies!

[@w8what575]

And even in the US r290 is the recommended drop in replacement for r22! Quit reinforcing this fraud!
