Need Professional Advice in A/C

[PHILIPLEUNG366]

I live in a two story Cap Cod house about 2000 sq ft total living space in Northern NJ. I have A/C with compressor outside the house and air handler in the attic. I have two heating systems both are gas. Steam radiator for the 1st floor with steam pipe giving heat to basement. Hot water baseboard heat for the 2nd floor. All the A/C and heating systems are pretty old. The A/C is not very efficent and not cold in hot summer day.
I am thinking of replace the old A/C, I have the following thinking:
1. Repace the A/C only
2. Replace with a heat pump (hoping the new unit can supply A/C and heat using existing ducts)
3. Replace with a combination of A/C and furnance (hoping getting A/C and heat using existing ducts).
What is the most practical way to change the A/C system with the planning for the phase out of the existing heating systems down the road? Could expert give some professional suggestions, Please?
I talk to most contractors and they don't suggest a heat pump. Their reason is that in NJ, the winter is cold. If the temperture is below 30degree, heat pump is not efficient.
I recently got the following proposal:
1. Lennox: Condenser 13ACX-036, 3 Ton, 13.5 SEER, 11.5 EER
Air Handler CBX32M-036, 35,400 BTUH
2. Goodman: Condenser GSX130361A, 3 Ton
Air Handler AEPF303616 3 Ton
3. Rheem:Condenser RANL-JEZ 3.5Ton,13SEER,11.75EER
Air Handler RHLL 4Ton
Any expert can comment on the equipment combination?

see the rules about pricing.

What do the contractors say about your plan, other than they are agianst a heat pump? I would consider a gas furnace with a heat pump some call it dual fuel or a hybrid. Now is a good time to invest in insulation.

Nothing wrong with using heat pumps in NJ.
