A 20 year old house. Best way to add attic Insulation,heat and ac are located there?

Answer 1

Although blown in can be cheaper, with your heat and a/c in the attic, batt insulation might be your best bet. You will need to be careful round your furnace and be sure the ducts are well insulated, especially in regards to the a/c.

Perhaps you could get a few estimates from insulation contractors in your area, and ask their professional opinion.

Answer 2

Most important things to remember--Know where the floor joists are so you don't fall through! BLOCK OFF all access areas including vents, your AC unit, attic door, etc. if you use blow in insulation. You can use cardboard or thin plywood to block off these areas so blown insulation does not go against them. Also watch out for bathroom vents--sometimes they are not vented to the outside, just into the attic, which is improper, but you certainly don't want to cover them up.
Batts are easy to do, but the blow in is not that difficult once you get the hang of it. Certainly will need a helper or two either way. Don't want to have to keep running up and down from the attic.

Adding attic insulation is the best thing you can do to save energy---I've worked in a state energy (weatherization) program for over 20 years.
