need advice on choosing a new system
Lots of great info on the forum. The more I read the more questions I have.
Currently have a 14 year old York gas furnace with 3 ton ac. Located in attic and supplies our second floor. We are in Maryland. The coil is on its last legs so looking to replace the entire system.
Have had many different quotes & options for many brands and have narrowed it down to 2 different proposals from 2 different contractors.
Carrier infinity 17 2 stage ac 16.7 seer 13eer
Carrier infinity 80% efficient 2 stage variable speed fan 58CVA070-1-12
Carrier coil CNPVP3717a-a

They also suggested standing it up vertical instead of laying down like the York currently is to help improve airlflow to the opposite side of the house that is always colder due to high ceilings and being over the garage.
One of the other guys suggested using a performance ac instead of the infinity since the performance is similar, infinity compatible and costs less. Does this make sense???

I've had several guys say not to put a 95% efficient in the attic due to possible freezing temp's but this guy and several others have said it's not a concern???
He also wants to put the pvc intake and exhaust pipes up into the steel vent currently in place so as not to require any roof/flashing work. Is this okay to do?
They are two different approaches and just not sure which one makes sense...Any feedback would be greatly appreciated.
