BeGreen said:How long do you expect to live in the house before selling? If this is short term, I wouldn't bother. It's hard to speculate on what future buyers may want or what energy product will be preferred by them.
If this is for over 3 years, then I would invest in my own comfort first. Maybe go for an efficient mini-split system in the living room and family room? They are quiet, efficient and may qualify for a tax credit. (Sanyo makes a 20 SEER unit).
Well it will definitely be at least 3yrs. Probably more likely 5-7yrs.
