So, Mr. Wade Byrd, the energy auditor, returned yesterday to see what we have done, and we haven't done enough.

His instructions weren't clear (he agrees) on sealing the return chase on our HVAC system.

That means taking this panel off.

Then one enters this space which is 18" x 34" x 8' raw.

He wants that lined with duct board and sealed with non-toxic duct mastic to force the system to use only properly cooled or heated return air to reduce the load on the system and protect the evaporator coils from filth. It will be a cool 12" x 24" (give or take an inch) sealed. Now these things are usually finished with sheetrock during construction.

Lyman can get in there, but I think he'd have a fit trying to do the work. I am going to go ahead and vacuum the thing with the shop vac, and decide if I can stand it. Whoever does it needs to be pretty darn slender. And I'd have to buy and learn to operate a nail gun.

And we just might hire someone else. Someone skinny and flexible. Gumby might be able.

UPDATE: No. No nail gun. 1.5 inch roofing nails and a hammer at broad intervals.

I've vacuumed the space out, made a call to Mr. Byrd for some direction, and set on doing this myself.

Now I need some materials -- 2 4x10 sheets of duct board, a gallon of mastic, and about a pound of roofing nails. And a small ladder that I can fit into the space.
