DuraCool at home

Not to confuse the issue, but there is an emergence of alternate, non-hydrocarbon based refrigerants.

This company approached my client with a "free" application to prove their performance...this is an organic additive that reduces overall refrigerant
percentage...

Food for thought.

Looking at the site you provided I didn’t see anything that really interested me. The boiling point is higher than the others listed. The lower the boiling point, the better the refrigerant.
It didn’t list one of the most important things — the latent heat of vaporization. I would want to know what that is before I would even consider using it. As to it being an organic additive, all of the things list are organic.
That just means that it has carbon atoms. They just don’t give enough information for a knowledgeable person to make a decision.

So in other words.

We've had persistent problems with our 16-year-old R22-based home A/C system icing up when the evening temp drops to around 55 degrees during the
spring and fall. We had an HVAC company take a look at it several years ago. The technician told me the refrigerant pressure was low, and the low
pressure was causing the icing condition. He recommended not topping it off because there may be a leak in the system, and it would be a waste of
money.

He then recommended we purchase a new $5,000 system that used the newer refrigerant.

Needless to say, we passed, and we just keep an eye on the outside temperatures to make sure we turn the A/C off before the evening temperature falls.
I don't think we have a leak in the system, but I think the problem stems from us having the compressor unit moved from the back porch (a really dumb
location) to the side of the garage, which meant running an extra 30+ feet of line set. I'm not sure the techs topped off the R22 after the move to
account for the longer line set. Now I'm concerned that it's just going to be crazy expensive to top it off.

Grab some R-22 while you can. It will not take much to top it off. If it had a persistent leak, all , or most, of it would have leaked out by now.

Basically add some R-22 and watch the evaporator temperature. Add until you get the evap temperature above 32F. I usually go for about 40 degrees.

You are done.

R22 is cheap if you only need a little. Your symptoms point that way. Also check for not enough airflow across the evaporator. With proper charge your
compressor will be happier.

Watched the video. They give the new pressures and Amp draw, but not the original data to compare it to.

Thanks, Ken, my thoughts exactly. It's had the same behavior for years.

Make sure the evaporator core is clean, not covered with an insulating layer of permanent dust that inhibits heat transfer. Easy to get to in the GMC.
Reduced conduction can make a difference.
Reduced airflow will also make a significant difference and can cause freezing. All sorts of obstructions have been found in evaporators I have had
to replace because of corrosion and subsequent leakage caused by the dirt buildup. GMCs don't get a lot of leaves in there, but Mickey really likes to
bring insulation and leave it and nutshells in so many little, protected places, like dormant air conditioning systems.
