I've been lurkung for a couple of days & this sems to be the place to get real answers.
I have found a comparison sheet on the internet at http://energyoutlet.com/res/heatpump/worksheet.html
I will ask companies to complete it when I start calling for quotes next week. If they complete the sheet I think it will be easier to compare apples-to-apples (as much as is possible). What other items should I add to this sheet?
I am not sure whether I will replace my dinosuar forced air furnace or replace the AC with a heat pump. I may even replace everything. But I will also consider $$. So you can see that I need all the advice I can get.
