Bait and switch or not?

I received and accepted a proposal for a new hvac system from a local company that has a good reputation.
A couple of days after the instillation I got the invoice in the mail. The listed components were different than those on the proposal.
I checked the numbers directly on the equipment and they matched the invoice numbers. I called the company and spoke with the rep who
put together the original proposal. He stated that when he and the foreman were about a week before the install they decided that the system would
be better with the different components. And he totally forgot to let me know. He wanted to assure me that the "changes were made for design and the best system for your home". Plus there was a reduction of a few hundred dollars on the installed components.

My trust, in what their telling me now, has been broken.
I was happy with the first proposal after doing a bit of research. Now the new system is completely different and I'm not sure whether to accept the change or
make them install the original quoted system.

Here are the 2 systems and the house facts.

1945 square feet home. Single level ranch. No basement. Old ac was a 25 year old, 3.5 ton Single speed gas blower. Don't know what the coils were, old type freon though. Everything worked ok but the ac was very loud and waking me up night. I thought i go ahead and update the system primitively before failures.

Proposed system components:
Bryant Preferred™ 80% AFUE 110000 Btuh 4-Way Multipoise Gas Furnace
Bryant Preferred series ac 3.5 ton single stage 16 seer
Bryant indoor CAPMP coil- 3.5 ton
I found a matching system on AHRI number 203669079

System they installed;
Bryant Preferred™ 80% AFUE 90000 Btuh 4-Way Multipoise Gas Furnace
Bryant Preferred series ac 3.5 ton single stage 16 seer
Bryant indoor CNPVP4821ALA coil- 4 ton
They gave me AHRI cert number 203670698

What I can gather then is; the the installed furnace is of lower capacity. The coil is now an N coil not an A.
And the coil unit does not match the condenser tonnage. 4 ton coil to a 3.5 condenser.

Online searches show mixed information about the oversized coil being ok to use.
As well as what coil is better; A or N.

living with the system for a week now, The humidity levels in the house are higher than I've seen and felt.
The company did say they would send a tech out to tweak the system.

It may be or not, but I feel that they are taking advantage of me by installing this system without letting me know ahead of time and getting my approval for the changes.

They have all their people telling me that the one installed is the better set up. Would anyone please share your thoughts on the 2 systems? So I can make a more informed choice.

Thanks!
