Hi all, thanks for reading my post. I’m currently working through the decision details of a furnace/air-conditioner install in my 21 year-old house in Omaha, NE with a very helpful company. The house is 2-story with finished basement, with a total of 4,000 sq. ft. The system will be a Trane.
The Manual J calculations are being finished. I’ve decided on a Trane XV80 VARI-2STG TUD100R9V5K(C) for the furnace. I’m also getting the HW VisionPro IAQ stat.
My problem is choosing the a/c. I’ve narrowed the choice down to either the XL16i or the XL15i. The 19i is not in the running.
My dilemma is that dehumidification is a somewhat significant issue with my wife and I. But it’s short of buying a whole-house dehumidifier (which I’m not necessarily against either). In addition to the hot, humid summer months, for a multitude of reasons we’d definitely like to run the a/c in the spring and fall when the outside temps are moderate but the humidity is still high.
I’ve read on this forum that many of the experts are less than impressed with the 16i because, if I understand correctly, the dehumidifying capability is less than expected due to the inability to do dehumidify-on-demand because Trane has implemented a funky wiring scheme for the 16i. In addition, the 1st stage/2nd stage compressor is 70/100 (according to the Trane dealer), and the split is not significant enough to see a major difference considering the cost.
Ordinarily, to my inexperienced mind, the 2-stage compressor of the 16i would seem to offer a better chance at dehumidification, EXCEPT for it’s apparent peculiar drawbacks. The 15i, according to what I’ve read on the forum, is a solid performer even with the single-stage compressor. As suggested by the experts in other threads, I could chose the 15i and let the stat and variable-speed blower do the dehumidifying job. Will that work as well in the spring/fall months?
Do any of the professionals here have an opinion on which a/c unit they’d chose under the circumstances? In your experienced opinions, is it a toss-up, or given the circumstances, is one better than the other.
Thanks in advance.
