From what the've told me.. big gains are available for pretty cheap.
My ducting is hung from the upper rafters... for starters, they cut it loose, lay in on the lower ones, and bury it in insulation.,
That alone is really supposed to help..
If ducting runs through conditioned space, not insulating it is a waste of energy. Running through conditioned space or not, insulating ducting will change the temp. dist. in dwelling. Areas at the end of long runs will be a bit cooler in A/C mode. That may/may not be desirable, but easier to adjust/control via flow control than not being cool enough.
Hey Bob
Let us know when you have them come back out to talk about AC info .
Im looking to get a better energy efficient AC unit.
First, get what you have checked out. Often, a tuneup helps. Then, insulate the duct work. I apologize if this does not apply, but there is always the unthinkable - turn the thermostat up.
Since this is always being preached, maybe there ought to be a section
or 3 here on what to look for, what to expect, and what to do about it.

Bruce: I'm not sure a section is needed. The net, bookstores and popular literature abound with information about home energy conservation. There for the taking.
