This can easily be done using one furnace with one air conditioner
(and if needed, a 2 to 3 zone zoning system).

I assume you are speaking of a natural gas fired furnace,
and using an electric air conditioner.

Technology today is more advancede and because of that,
easier to manage home comfort.

This is what I wold use in your situation.
A 96% AFUE gas furnace with a variable speed fan system.
An 18 SEER 2-speed electric air conditioner,
(yes, with TXV on evaporator)
A Thermostat that not only controls desired heating and cooling
comfort levels, but controls humidity levels in the home as well.
(dehumidifies via the A/C as well as operates an add-on humidifier)

It is fairly unlikely the A/C does a very good job at dehumidifying. High
SEER units tend to be poor at latent heat removal.



Here is the equipment I would reccomend, if I were speaking to you
"person to person."

Air Conditioner:

And I would research costs associated with captive designs (proprietary
repair parts) with Carrier and a few other big names.

I am not suggesting they are not good units, just lifetime cost of
ownership (repairs and service) tend to be higher with some brand name
equipment.

Thus, add the cost of a long term service contract when getting quotes.
