I am looking at two different systems for my home.
Approximately 2800 sqft 2-story home.
I current have a 2 ton and 4 ton unit that are about 20 years old.
I live in Houston with very hot and humid summers.
I am looking at the American Standard Gold Xi 15 series air conditioners for both units with a Platinum SV variable speed communicating furnace. My installer recommends upgrading to the Platinum XM allegiance 16 unuts due to the 2 stage cooling. The ugrade would cost an additional $900.
What does everyone think of the two stage cooling units, given my climate, and would the upgrade be worth it.
