DONT BUY CARRIER they are cheaply made trash
get a quote on another trane system or lennox followed by rheem/ruud system
carriers are barely one step above goodman and other "no name" brand cheap systems
Getting two complete new systems soon. 2800 square feet. I want quiet.

Most of the HVAC manufactures, of which I think there are about 5, producing 50+ name brands, have many different quality lines, and I believe Carrier has has lower quality lines (cheaper) made/assembled in Mexico and higher quality lines made/assembled in the USA. So you can do your homework on this.
The thing I’ve learned over the past couple years in looking into this is that the quality and experience of the installers/HVAC techs is far more important than the equipment manufacturer per se, so I’m sure a mid to high tiered Carrier/Bryant unit would be fine when installed by a top of the line HVAC firm. Since you mentioned “quite”, and I know what you mean as I have a “loud” unit (air handler component), and when I replace it I will be wanting a much quieter system as well, I’d certainly look into Carrier/Bryant models that have higher insulation noise reduction characteristics. Two-Stage and multistage units (more $) are inherently quieter than single-stage units but there are considerations that must be looked into if choosing that option.
I’ve got close friends that replaced their 2 old units with Bryant’s a couple years ago and are very happy with them, but maybe more importantly they are very happy with and trust their installer.

Seven years ago we had an installer put in a Rheem unit but he felt their coils weren’t solid so he went with ADP for that part. Solid choice so far and each Spring we have it inspected. Never had to have any refrigerant added.

Sounds like to me you have the most difficult issue resolved, a HVAC firm you've dealt with and trust. Are your air handler/evapator units in the attic?
Does your new home have a semi-conditoned attic (spray foam insulation) or is your attic vented with traditional fiberglass insulation? If the latter, ask the HVAC tech if their are any potential condensation issues they have experienced with multi-stage units in vented attics with traditional insulation.
I understand there is potential for condensation within duct work, if duct work and air handler is not properly/sufficiently insulated, which has to do with the high temps/high humidity present in vented attics in summer, combined with slower speed through which conditioned (cooler) air moves through the duct work much of the year with multi-stage systems. Not say this would be an issue, but it something you should be aware of and the HVAC Tech should be able to answer with certainity. This should not be an issue in a conditioned/spray-foamed attic because the temperatures are much cooler (as much a 20 to 30 degree) in the attic.
Also does your HVAC company conduct a Manual J load to size the units for your home? What size units are they proposing to install for your 2,800 sq ft home? I'm going to leave with this statement from which I've read numerous times on HVAC Talk forums stated by HVAC techs trying to trouble shoot problem homes, the most common problem they see is HVAC units which are over-sized for the home with undersized duct work. You can do your own rough manual J calculation using this program to size the HVAC units for your home to see if it matches what they are proposing. LINK

That seems to the case now days regarding evaporator coils, I've read where many say expect 6 to 7 years before they leak, even though they are warranted for 10 years but you still have to pay the labor to replace them. I believe, much like cars today, to gain energy efficiency and save cost, they don't build the units as robustly has they once did. And the high temperature extremes in the vented attics where many of the evaporator coils are often located are more severe than the conditions outside where the condenser coils are located.

You can choose from these top 5 AC brands Trane, Amana, Carrier, Lennox, Rheem. All the brands are high-quality and durable.

I have the Trane XV18 and can't hear it running. Great humidity control.
