I dont deal with these issues daily as many of you do, so thanks for the advice.

Selection

Carrier PRODUCT DATA catalog is available as PDF but a little too large (1140 K) to attach to HVAC-TALK site (976 K).

With a 100k BTU, the EER drops to 11.6... and even lower with a 80k BTU.e power vent is

I wanted to match it to a 80% 70k BTU furnace and the ratings dropped into the 14 SEER range. They don't match well with narrow furnaces.

The quote I received was checked by the Carrier rep to match the HNA6 and the furnace, and it sounds like the specs are poor with the 16. Is the 19 SEER also narrow, making the heating specs fall apart, or just the 16 SEER Infinity. This would go under the house where the power vent is currently located. Do you recommend 70-80% or a more efficient 95% furnace? My contractor apparently is not bothered by this, or more likely doesnt know.

Not sure what the issue is.

The 25HNA9 qualify for te tax credit,$1500.00,in the 2,3,and4 ton sizes,likely soon in the 5 ton.

Regarding the furnace,where do you live?

Live in Virginia and the 3 ton unit quoted was dual fuel natural gas. I am concerned now about the low efficiency in the Infinity furnace mode as described by motoguy128.
