Tech question about variable speed compressors...

[Bob Sisson]

Who ever wrote that most of this list is above the A.R.T. is right.

I consider myself am educated consumer... I ask lots of questions... and lots of people don't like that.

When the were going to install our last system, I asked that they purge the lines and then draw a hard vacuum for a long period.

Well, when they went to instal it, they had a vacuum pump, but no purge gas, and no vacuum gauge... they didn't appreciate when I asked where those were...

Yes I am a cheep ZOT, but I am willing to pay for quality, and it is %#$@! hard to find.
