Hey Eugene hope all is well with you and your family. I respect you and your comments very highly.. You and John Williams Jr of the Carrier Co. are one of the very very few folks that I consider my equal n the ac industries. I might not be the best boss or businessman's in the world, but if nothing else i know air and ref flow!!!
I have noticed that many of the so called techs are so less skilled and inexperienced than that of 20 years ago. What is really scary is that are trade is dwindling very rapidly. I recently gave an exam to a group of techs just to see what they knew. How to change out a 3 ton burnt out compressor, the procedures from start to end. It was scary the results over 85 % failed or even close to pass the simple 5 minute test.The average Joe blow doesn't know basic refrigeration.
Most owners don't encourage reclaiming old ref much less own a recovery unit. Most techs out there don't carry a micron gauge, dry-nitrogen, or even a sling psychrcometor. 410a is a very very unfriendly blend and charging is so critical. I have read so many questions that have come in and just shake my head. They go buy a set of gauges and a EPA certification from a local parts house and bam their are in ac business ( lmao rotff smfp ).
Then after 2 or maybe 3 years they decide that thy are a commercial expert technician. Now Eugene I got to share this one with you. A very close friend went out to check on a job, a local contractor did the working blaming the manufacturer company. The contractor mad now at my friend because he shows the contractor that the water piping was piped backwards. A very simple 50 ton water cooled chiller with a remote water tower. Now how stupid can you get. Back to simply charging, why is it so hard. If its in the cooling mode with a cap tube or fixed orifice use super heat dummies. Now it has a tx valve use sub cooling dummies. It does not matter if its 410a or r-22 or even 421a.
Guys just wanting to help, and please take time to clean both coils and pull the blower wheel. Also if it is a furnace with a secondary heat-exchanger clean it to.
PEACE BE WITH YOU
