Since you live near the shore, I assume humidity control is important to you. Therefore I would suggest you stay with the 2-stage units. Your variable speed furnace should be a match to all of the condensers you have listed. Option 3 is overkill in my opinion. But it is not that much more expensive after the NJ rebate. See if you can get the Carrier 10 year labor warranty included in Option 2. The labor charges for repair can be very expensive. I don't think a heat pump makes sense. You have a 95% efficiency furnace and I suspect you electric rates are in the 18 cents per KWH range. The gas furnace is cheaper to operate at almost all temperatures.

Ok, I am sorry for bugging yall again... but I do appreciate you all helping me. I have been thinking. How does this sound, and tell me please if I need something else? I am going to ask for the Infinity Gas furnace- and matching control (thermostat?) as I said, I really don't even know what to ask for but in doing research and carrier left me a brochure I was reading through it, and see some nice reviews about it. For now I am not concerned about a heat pump, or even an air conditioner. However, is there a such thing as an air conditioner that matches the infinity gas furnace? Please, I know yall base answers on best product for least amount of $, however, I have only one shot to get the funds for this furnace. and I want the best. the best because I know it will last me a long time. I do not care about bells and whistles, No. I just want the best. and as before, tere will have to be new ducts, vents, and anything else that goes with a new system. Is one stage better than 2 stage? what is variable speed? what is a box filter? what is a condensing fan? please, please help me figure this one out, so at least I will know some of what I am asking for and not just accepting what they are telling me? and what seer? of furnace should I ask for or need? thank you in advance. I am sorry for being a bugger.

Well right now I have a temporary 25"x20"x1" pleated Merv 8 but the engineer and the contractor know that we are planning to use a 4" Lennox Healthy Climate 16 Media Air Cleaner. Is that going to raise the pressure? Regarding the condition of the furnace, are you talking about the corrosion you see? They think it's all fine, but the fan was under water as well as some of the boards. Also now the heating has been running for 2 days and the humidity didn't drop at all, 58% in the house but set to 45% Also the heating has been running for the past 2 days but the humidity level on the controller said 65% but it was set to 50%. I checked the sticker on the units to see if they installed what the engineer specified but it doesn't seem like they did.
