Was calling around for a couple of quotes to upgrade to R50 and it seems people want between $1.10 and $1.25 per sq. foot to bring up to r50. Since we have about 1350 square feet that's a steep cost, much more than I anticipated. I thought it was only going to be $800 or $900.
House is heated with a 96% afue natural gas furnance and cooled with a 10 seer central air. Central air is years away from being replaced as it's a well built unit. At least with cooling we have a variable speed low energy ECM blower and A-coil is clean as brand new and the refrigerant run to the compressor is short. Nothing more can be done to improve the efficiency of the hvac.
Is there any way that upgrading to R50 in that attic can pay us back in energy savings to make it worth our while? Any way to calculate this? Windows are in decent shape (installed 1984) as are doors. Very little draft considering the age of our home.
Anyone have any expierience and numbers to share on this matter?
