Converting R22 AC Unit to R422B. Plus Leak Search On 2 Units! 

SUPER discussion and execution. You are a master at this work. I wish you were my technician since you just saved me a good amount of money.

I'm just some dufus home owner guy out there. But you are BADASS with your basic technicals and also with your video processing. THANK YOU. My problem, which you are helping with, is my passed fathers home unit. It's a R22 system and at least 30 years old. Major brand, I forget which right now. Over the years I've already repaired - moving the drip conduit from the indoor blocked drain to the exterior; the circuit board (which I got for $40 after waiting awhile) which had the spark igniter failure; the condenser capacitor; the condenser exhaust fan; the handler fan (twice); and other minor maintenance. The unit has been great on heat (after the control board replacement), no CO problems, but the cooling function has gradually declined over 20 years. I recently became aware of the schrader valve thing and this is where I want to compliment you. You are not afraid to share pertinent information. THANK YOU. Your video CONFIRMS the idea of FUCK IT, REPLACE THE SCHRADERS - DO IT - DO IT NOW (The Matrix) I observed your use of valve core removal tools and end hose cutoff valves, all which should be part of any ACmaintenance regimen (THANK YOU). I now have possession of these tools. They are an integral tool for any ac mechanic. They are not "neat" or "cool". They are essential (THANK YOU). I now am "hunting for red october" for a local technician who knows what for on conversion from R22 to R422B. My father left me some R22 but I don't know where it is now. And anything that can reduce my costs to get the old unit running is valuable. Anything you could offer about oil calculations would be nice. THANK YOU Once again - BADASS.

Yehhh it is what it is and it's a temporary measure the customer dictates the way forward considering its to get them through and its good business, super video on these two jobs excellent presentation of work. 👍👍👍 always very interesting with a good sense of humour.

You're a good tech .... kick that junk off the roof !!

422b runs low suction with r22 metering device. A larger piston will work or adjust txv open more. If not your saturated suction will stay under freezing.

As always, great work Jeff 🤙.

Just out of curiosity and this is just a question and nothing more. Why use R422B over say MO99(R438B) or one of the others available? I know there are like 10-15 choices. I found R438B or 422B are the two best besides R22 itself. I still have two full R22 jugs for specific systems. But I have also been putting in new compressors and TEV's and using 410A since the coils for R22 are so stout and mostly copper, they work amazing, if you can find 5-ton condensers that are still good, the swap is quite affordable. So far I have done four and they are all pounding away just fine. The newer coils and condensers are so prone to leaking, an old timer asked me why I didn't just swap the compressor, TEV, clean-out the lines and run 410A? I didn't even think about it before that day. I am shocked how well it has worked so far. So I am always curious why some techs use different "drop-ins" It is nice not having to change oils with R422B and R438B, that is why I use those two.

Great video!

407c is the best replacement for r22

I have a question if you dont mind? My heat pump was changed out to R422B.. I was charged $150 for each pound. That seems very high. I dont mind paying a reasonable markup but that seems excessive. Question: What is considered a reasonable markup. My markup seems to be 500% or more. Is that typical or should I be talking to the company?

I would recommend use 407C better buddy, works much better than 422B for air conditioning even pressures are better

How do you like that recovery machine? Have you tried the Apion G5 twin?

Is this an air handling unit with fresh air? In my country i never seen ahu works on R410? It’s either split system or big ahu

We service close to 2 thousand systems have been topping r22 with r422d for years with no problems pressures close to r22

You must have spent your 8-hour shift on this project. Do you prefer long jobs or several short jobs per shift?

I've tried to fill my R22 unit with 422D and thought that it was difficult to get the settings dialed in. There seems to be a huge lack of info for 422D but I'm a diy guy. Does 422B run similar as D? Or are they totally different animals? Thanks so much for any advice

Jeff, great video. Can you give me an idea what your company charges per lb. for 422B freon ?

I was quoted $200 per pound for R422b. So that's why I'm looking at all these videos.

Hey ! What is temp conservation
