A contractor recommended a GCH950703BX that has 69,000 BTUs per hour. This house has double paned windows, moderate insulation, 1000 square feet, and is in zone 4. From what I've read it would only need 45,000 BTUs. What would you recommend?

The furnace needs to be replaced. Trying to figure out what to get.

The first question is what is the BTU of the current furnace and how old is it? If its less than 69k then you definitely are not getting the right size furnace because it is more than likely that your current furnace is 15 or more years old and in that time there have been numerous improvements made to furnace efficiency. Also, if the current furnace is around 69k BTU then you probably could use something smaller since newer furnaces are more efficient.

Also, if you believe the HVAC tech made a mistake doing the load calculation then you should bring in another and get another estimate for the cost to do the work as well.

Lastly, it may be that the HVAC tech actually did do a good job and incorporated variables that aren't being included in what you are reading.

Either way, you would be smart to get another estimate on the cost, which requires sizing the furnace.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
