very unlikely could have frozen. We had a very mild winter Thanks!!

that high efficiency vents be installed in lieu of those in the ceiling now. Lastly, a variable speed air handler was recommended in that it would make it much more energy efficient. So as far as putting the money where it's needed most if we cannot purchase all that was recommended:

1. 14 SEER, not 13

2. Humidifier

3. New vents

4. Variable speed air handler

As the first 2 were said to reduce energy costs by 25% and the air handler by 25-35%, gosh, are we going to be able to cut bills in half? Seems a bit unlikely...

Note that the house is 11 years old, 2340 sq. ft, and high ceilings. I thought the house was cooler in winter b/c of the heat rising. Must be a 10 degree differnce in warmth at my height and 10 ' up. Was told the humidifier and change of vents would make it much more comfortable in winter. I'm wondering if the heat still won't go toward the ceiling.

LASTLY, how do I know what size of a/c unit I currnetly have and which SEER? Also receiving conflicting answers. Thanks!!

heat goes to the ceiling. Doesn't seem to matter much if I get space heaters. Anyway, he says if I add a humidifier and do the heat pump it will be less heat bill and more comfortable. But my cost goes from $4400 to $10,000. As I will only live in the home 3-5 years I don't think I will recover the difference. Comments? Thanks!! And do I really need a Trane or can a lesser quality unit suffice since I really don't want to invest for the long term?

or good chance of system failing in next year or 2 anyway? He says units typically need replacing after 10 or 12 years so don't want to invest in new coil if system will go out soon anyway. Opinions? Thanks!
