The airflow through the vents is minimal, even though it's cold, and the AC is running continuously for 8-16 hours a day; my thermostat is set at 78, but the indoor temps are getting up to 85. Very inefficient and expensive!! I had the system checked out a couple years ago, and the guy said that the unit is operating correctly but the blower is just underpowered.
So, my question is: can I just replace the blower with one that produces more CFM? or will I end up with other problems as a result such as electrical or ducting? The York company said that this unit sounds like it was designed to be a furnace only (based on the blower size being 1/5 hp), and that it probably was adapted to handle the AC, which makes me wonder further about consequences of increasing the blower outpout.

Of course it will.
well, sure-- except that the whole system will surely cost many more dollars than the blower.
I'm sure the duct work is poor, too. Still, my question remains about upsizine the blower...
Don't waste your money.

I'm not saying a little more air on the evap wouldn't slightly help the matter, if the blower was undersized, but 2 tons is 2 tons. Unfortunately physics won't let us create another ton of A/C by adding more air flow.

As for sizing, as mentioned, I did talk with the York Co, and they confirmed that 2 ton is appropriate here. I also checked this website and got the same confirmation (for Zone 2):
atty, I appreciate your comments; they are appropriate. But...I'm just trying to make a bad situation a little more manageable here. If it absolutely won't work (the more powerful blower), then fine, I'll pass, but if there's a 50/50 chance it will, then I'm willing to move forward.
Any more comments will be greatly appreciated!

As for the landlord, a bigger motor is not going to cause any damage, assuming you don't exceed the current rating for the fan relay. In short, if you could snag a motor somewhere for about $50, then what the hell, but for me, $200 is a bit more than I would want to spend on that roll of the dice.

well, we can't point fingers at York on this-- the chart is from ACDirect.com...
Without casting aspersions on York's chart,
Anyway, the intake is showing 76, and the output is 66. Maybe I can find just a motor for $50, that would be great. Would a motor upgrade be ok with the same blower/vane thingy? I was thinking that the vane blades might be different on a more powerful unit.

unfortunately, these windows are the aluminum frame type; I can't see how I'd get a window unit into one of them. They also are part of the problem, because they provide little insulation.
Put the dough toward a nice, portable window unit. When it's leavin' time, unplug it and take it with you.
