Hey Go-Redskins.... I liked your analysis of propane vs. electric and I'm using it to try to decide on my particular situation and you make a good point on dual fuel system.

Thanks for the reply, I will make sure the HVAC guy knows about the windows.. Hey, if I can reduce size, great, less cost to buy, less cost to run. I will get with them perhaps this week and discuss...

In our original quote we were using a package dual fuel system (trane 1200), but now, we have decided to go to a split system, so, does that mean my dual fuel system is out? I am not sure if now the...

I found it interesting to see that Goodman has a fairly good explination on their site regarding a higher seer rate for their units, at the same time, I can see on a number of sites that the Goodman...

Well, Im not trying to be a pain, but, I just thought if the companines can say that X seer is 10, 20, 30 percent more than X seer that using a control model one could get an idea of costs. I do...

Maybe I'm to much of an engineer, but I'd think that there would be some way to estimate the usuage costs, just plug in the KW price and how many hours of opperation. I would suspect that there is a...

Well, first thing I have done is called the HVAC contractor and I am asking him for more details re energy calcs and costs, I just can't get over the difference in the upgrade units.. I am asking him...

Thanks for the info on the sizing, I am just going by what the two contractors are bidding, both have said they have done the load calcs and have come up with the same sizes. The house is a raised...

One of the considerations along with the efficency of the units I am looking for a quiet system, I like the idea of the variable speed fans in the system. The two contractors here bidding one is a...
