It will if the system is correctly sized and properly installed.

THe *BEST* option is to have a correctly sized and properly sized comfort
system installed. A 2 stage system will dehumidify as much as 30 times
better than a standard system.

Yes you can get one that will be correctly sized for your home

Call a local, *competent*, licensed, insured, professionally trained, HVAC
technician to do a complete survey and analysis of your home to see what
it
actually needs. We can't *SEE* it through the computer screen.
Discuss all of your options with the tech and tell him about the "energy
saving" improvements you want to do.
If you need to find a competent, local, tech, then go to the manufacturers
web sites and they will have a page for locating a top contractor in your
local area.
