Oh yeah, I completely agree. I've never really had any issues with units when I've had to use them as a "drop in".

I've never used it. Only 422B and the M099 stuff

That and Midnight Club Dub Edition 😂

@@AB_HVAC Seriously that was fire!!!

Midnight Club Capture The Flag around tha bity was lyfe! 💯💯💯

@Jikktastic out of all the "remastered" games I need a remaster of Dub Edition 🔥🔥🔥

I marked it for MO99, and if R22 is already phased out meaning it's not being manufactured mixing the refrigerant will mean they have to get rid of it all...meaning less and less R22 on the market. Everyone already tries to get rid of R22 systems. AND with that unit being 23yrs old, compressor and evap coil being replaced, there's a possibility someone didn't put R22 back in there from those jobs. I used what I had. I'm not allowed to buy R22

If you check from R to G and it's 0v G is being energized, same way G to C reading 24v means G is energized. More than one way to catch a fish my guy

​​@@AB_HVACif you measure R to G and you get 24v, fan is not calling. If you get 0v, fan COULD BE calling, or you have no power on R. There's 2 ways to get 0 and only one way to get 24. Also you want to know the ACTUAL voltage passing thru G in case the transformer is weak or there's some voltage drop in the wires before it hits the relay. So that's why C to G is better, since you're comparing against a known reference of 0.

@Mo4Honesty if you have no power on R, you won't get 24v from G to C unless you're bypassing the Stat and going straight to the transformer. All I'm saying is if you're checking to see if a blower is running and you happen to check from R to G, you should read 0v but if you check from G to C it'd read 24v. Wasn't saying dude was wrong, just that there's another way to check for it

@@AB_HVAC neither way is wrong, but G to R is inconclusive and gives you a less definitive answer. Suppose blower not running and R has no power and you check R to G and get 0v. You think G is energized but it's not. Alternatively, check C to G, get 0v also. Now you KNOW G is not energized, for whatever reason.

@Mo4Honesty I get that. I guess R to G would just let me know the thermostat is atleast working making the G call

😂

🤣 he alright, he a big boy

@@AB_HVAC imma start a channel cause of y’all I’m about to start my refrigeration tech journey next week Monday. Graduation ceremony the Tuesday after that.

Btw Jake I’m fat too my boy 😂

@drewtab18 man congrats on that. I wish I could touch more commercial equipment. First real RTU I was thrown in front of I was nervous. But when I finally figured it out I felt more accomplished than any residential service call made me feel

In all actuality it depends on the "drop in" I've had better luck with 422B (NU-22) than I have with 438A (MO99). And I'm basing this off of let's say a compressor changeout. I've found MO99 just runs colder but NU-22 is closer in temperature for my superheat. You could go back to those systems (without adjusting your gauges for those refrigerant and assuming it's R22) and find that the MO99 system is sweating and running a bit colder, but the NU22 you'd find closer in temperature

But that's just how I see it in the field. And honestly, I can't recall one system we used a drop in on, and then come back to find it messed up the same compressor. I know one system fresh in mind that to this day, it's still a 2002 Goodman Heat Pump that I have added NU-22 to it and a UV Leak Dye/Sealant and we haven't been back to it for refrigerant issues.

Thank you for the reoly

Well I just meany that in the sense of the dude at the counter telling me there's no such thing as a drop in. And as far as the price, a drum of R22 at a local distributor is near 2k, where MO99 is 25% of that. Pricing per pound, there's a DRASTIC difference in price. I know exactly why we won't get R22 lol.

@@AB_HVAC r22 is available at other distributors for much less than that, plus many contractors have a supply they bought much lower than even what they would need to pay for a new jug of mo99 with additional money out of pocket instead of already paid for.

@Mo4Honesty that must be your area, but giver or take around $100 that price of R22 is insane where I'm at. So for companies that deal with home owners and they say "R22 is 300 a Ib, your unit might need 4Ib" it's a lot easier to sell a replacement that way. We just don't use R22 if the other refrigerant can closely get the same job done but cheaper
