Hi--I'm doing this on my own, since my 90 yo father (a general contractor for 40plus years) recently died--he wouldv'e known how to sort this out...
anyway, I'm in a tri-level with cathedral ceilings on the main floor so we freeze every winter, & our family room on the bottom level is too hot in the winter & too cold in the summer. I think my cubic footage is around 21,400 (I think that's what he said) & my old GE is 10SEER.
A Trane salesman just came out & quoted for the XL15i & XL16i (4ton). I've got to make decisions by Wed. @ noon, in order to be eligible for a $3to700 rebate. He also suggested a 25kw variable speed air handler.
OK, my questions: 1-is it worth the extra money to do the 16i
(getting the 2-stage); 2-is the clean effects unit decent & worth it; 3-is it a good idea to add an aprilaire humidifier?
I just want to be warmer this winter--& more balanced out! (I asked about zones but the salesman said it'd be very expensive & require tearing into walls). Thanks for any direction you can give me!
