Whats the diff between 1 stage and 2?
Tell us more about the tax credit

Single Stage is on/off, standard system.
Two Stage, it starts up at about 65% and then switches to Full if the temp is more than two degrees off. More advanced system can also dehumidify by running low speed for a long time.
Variable Speed is like Two stage, except 40% to 110% capacity and very small increments. Even better humidity control.
Humid areas really benefit from the Two Stage and Variable Speed systems.
Tax Credit is $300 per unit, maximum $500 if the SEER/Components are right. Meh. $500 on $12K.
