I liked the examples of different charge levels and their temperature splits and super heats. I think that kind of stuff helps build intuition about his things are supposed to work.

The section on mini split fault finding a low charge is most insightful. I will us this procedure next time I'm standing in front of a low charged mini split. Thank you Tad!

Recovery to liquid port on recovery tank is not bad, but is much faster and better on vapor port, because there’s no dip tube restriction. Great video Tadd

Most brands come with a pre charge amount. Btw I can see where the refrigerants probably leaking out…them quick connect/push fittings on the lineset are a call back waiting to happen

what is the proper way to do this with a 3 zone system Thx
@michaelmolter88283 ай бұрын
My multi zone minisplit has electronic expansion valves on each zone, so the computer controls the superheat sub cooling by how much it opens the valve. Because of this, to measure the charge, the only option is to pull the full charge out on a scale, and add what your missing when you put the charge back in. A correct charge is less important on a minisplit because of the large reservoirs in the outdoor units and the electronic expansion valves.

Pardon my ignorance (still a learner), but in this situation here, we have a running system with its service valves already opened, and it has had refrigerant circulating through the entire system. After recovering the existing refrigerant, you indicate a vacuum of course needs to be pulled. If using a micron gauge, is there a recommended way to minimize the oil getting on the sensor? For instance, vacuum down and nitrogen purge 2 or 3 times (without the micron gauge connected), and then do a final vacuum with the micron gauge? Or will your gauge get contaminated regardless since you're pulling a vacuum on a system that has already been in service (residual oil on all the piping)?

I love all the comments chiming in on how to do it professionally. Yet when, as a home owner, you call a so called professional to get work done, a good amount of them, won't go through all the necessary procedures. Not only in the HVAC field, but most any construction field. Trying to get the right tech to work on a job properly can be tiresome. Having experience in the field of choice needed is almost a pre-requisite. Obviously there's good and bad, but the average Joe won't know the difference. And yes, I do have pro experiences in other trades. That's why I learn as much as I can from some of the more professional YT videos who actually teach what it is needed to learn. Being retired gives me that option. And it ain't easy finding the proper techs in any field, that's for sure. I'm not going to say much about what the right videos are to watch for HVAC. Although I will mention AC Service Tech LLC is very thorough.

@TaddyDigest2 ай бұрын

@motocross030872 ай бұрын
@@TaddyDigest thank you. I’m guessing different by unit. My Fujitsu halcyon has a rotary compressor and tech told me it’s an open system so as long as I have all ports open I can recover from any service port and I can vacuum/charge from any port. Recommendation is to for example pull vacuum from two zones at once to help expedite.

Bro stop living in the past. 20 years ago nobody would vaccum or use nitro. Just purge the lineset with refrigerant and call it a day and the AC's would last for 30 years. In todays world this is not the case. For better or worse you MUST pull deep vaccum and able to hold it. Also, braze by with first purging with nitrogen and then flowing at a lower rate. That's how is done professionally. I am in the trade 6 years and I see hacks all the time. Just because you installed a system and it works right away it doesn't mean it will perform at its rated capacity or last as long.
