    We had a Trane dual fuel system installed last November when the heat on our 15 year old unit failed. We just noticed that there is water leaking from the ducts in a couple of places in the crawl...

    The heat load for the downstairs was calculated as 38000 btu. I don't know how "accurate" the calculation is.

    They told me that at 25% control the difference isn't very noticeable. Whether that is really true or not, who knows. I guess it is something to consider. I imagine it depends on what temp you like...

    I just found out that our electric provider has a rebate program for heat pumps (not dual fuel). It is $300. In addition, I would have to participate in a...

    I'll have to think about this a little bit.

    I was wondering about the setpoint. You mentioned 30. The two contractors who quoted me on the dual fuel mentioned that they set it at 40. Why is this?

    So the savings is a little better than what we originally thought. So it seems to me that if I knew I would be here for 20 years, the dual fuel would be the way to go. Otherwise, it really comes down...

    Are we talking about packaged system here or split system? I think one thing I didn't make clear is that we have dual zones. The downstairs is controlled by the failing package unit, and the upstairs...

    I understand. I wouldn't be here if I was in a huge rush. I just don't want to take a month. I was just wondering if you had any advice on specific systems (HP vs gas/electric vs dual fuel).

    We have a 15 year old Trane gas/electric packaged system that needs to be replaced (heat went out and it isn't worth fixing). Since I need to make a quick decision, I was looking for advice.
