Im in the process of deciding what to use to replace an ailing 12 year old builder class Rheem 4ton HP. The home is in South Florida (Vero Beach). My previous experience (in NC) was with a Carrier Infinity Dual Fuel package unit that I absolutely loved. Comfort was far superior to the builder grade Carrier gas pack it replaced. Based on that my first instinct for Vero Beach was to go with another Carrier Infinity (Infinity 19 instead of Greenspeed for cost). However, Indian River County has zero Carrier dealers.. nearest dealer is 50 miles away. IRC seems to be Trane country! This basically leaves me with two choices... XL16i and XL20i.
XL20i would seem to be very comparable to the Infinity 19... The communicating system should allow for dehumidification on demand and best comfort. XL16i isnt communicating so no DoD. I saw a thread in this forum where a comment was made that the 16i did not do a good job on dehumidification on stage 1 which gives me great concern. My number one concern is comfort. Im going to be in the house for a long time.
Is the claim that 16i doesnt dehumidify well on stage 1 true?
From a comfort perspective, what kind of difference should I see between a 16i with 803 stat and a 20i with 900 stat? Significant? (assuming matched systems)
What should I expect as a rough cost delta (in %) between a 16i and a 20i?
Im struggling a bit with understanding how each of these systems handle dehumidification. With my Infinity in NC, I didnt see any 'overcooling'... I dont think I ever saw the thermostat indicate temps below setpoint. Is this because of Dehumidification on Demand? Does DoD eliminate overcooling? If so that would seem to be a big point in favor of the 20i.
One argument I hear against the 20i is that its complexity could have it down for days for parts... That argument was made against all communicating units. (I initially thought a 16i communicating model was available but it seems that it has been discontinued).
Feedback would be greatly appreciated! Thanks.
