As a York/Luxaire dealer I can assure that York does indeed have 12 seer VS units.
With VS blowers there is a hum terminal, that you hook a humidistat to, when the humidity is higher then this set point the CFM is reduced to remove humidity.
When the humidity is lower, the VS goes to its higher cfm, to cool like most psc motors.
It also allows many people to set their stat higher since the himidity is lower.
Nothing wrong with 45% rh in summer.
Also on the milder temp days, the normal psc blower is moving the same cfm's as if it were 95 outside, so you don't remove as much humidity due to the short cooling cycle to maintain temp.
I take it you haven't installed many.
Thanks for the information. I'm thinking that a 12 or 13 SEER with VS and TXV, and an 80% 2 stage VS furnace is the right choice for my climate (mild winters, hot, dry summers). Most of what I have read on this forum leads me to believe that the higher SEER units (16 plus) are not necessarily worth the extra money. Now that I know that York has this equipment configuration I can solicit a bid on York equipment. One last question. Do all York AC units have scroll compressor? Thanks
No, I haven't installed any. Still trying to decide if they are worth the money, right now I tend to be against for menetary reasons ( install & repair )
Plus, I'm just a K.I.S.S. man. I tend to believe that simple lasts longer with less repair costs.
But, am open for a change of mind. Thats one thing I like about this site. Gives me a chance to hear other opinions on subjects, maybe one of ya'll will make me a "believer"
Am going to be running my own test this summer - will keep tract of humidity levels. Right now I don't think that humidity is such a big problem ( as I have lived without caring about it for all my life ). Maybe, I'm wrong - will find out this summer

No, most York units have Bristol compressors.
If your putting in a VS in your house or some one elses, use a txv, and a humidistat, the results will be well worth the money.
beenthere, I know you sell York, so what is your opinion about a scroll vs. bristol compressor? Is there any real difference in performance or reliability?
I take the good with the bad.
The York Affinity uses scroll, the rest of the line uses bristol.
Already had a recall on certain 2 stage scrolls.
I've had acouple britol 50/100 2 stage fail.
The bristol is a tad louder, but with the sound blanket you don't hear it much.
Since on higher end equipment you get a ten year warranty on the compressor, I don't feel it makes any real difference.
But, somebody will disagree.
If you go with York, go with the Affinity line, seer starts at 12.
I'll specifically mention the Affinity line to the York dealer. For AC the York website only discusses a Stealth line and a Olympian/Latitude line. Just goes to show you not everything is on the website.
Thanks for the info.
Your welcome, the Affinity is replacing the Stealth line, as the top of the line.
Rumor has it, that the Stealth is being obsoleted.
Heres a link, click on the a/c brochure pdf.
And the Affinity 12 or 13 SEER is available with a VS?
The 13 can be single or 2 stage outdoor, and the indoor unit is VS.
As far as a VS versus a multiple speed fan: Does a VS fan adjust speed automatically, or are there setting options?
On a multiple speed fan (such as Trane XL80 furnace (4 speed fan)) how is the speed changed? Does the user select the desired speed, or is there an automatic function?
A VS is set by dip switches on the control board, for the cfm your house requires, with the addition of a humidistat, it will run slower if the humidity is above the set point in cooling, and when lower it will speed up to the max set cooling speed.
Not sure if the trane is set to just one of the 4 speeds, or if they have a relay to use 1 speed in cooling, and another in heat.
