[QUOTE="beardking, post: 2768931, member: 31421"] I'm not an hvac person, but I'll relay what I did and how effective it was. When I lived outside of Dallas a few years ago, our house was a standard '70's ranch house with basically no insulation in the attic and all electric heating and air. I was going to have insulation blown in, but when I was talking with insulation guys, their suggestion was to first have radiant barrier installed throughout the attic. We did this and can say that our electric bill in the summer dropped from around $300/mth to about $175/mth. We didn't add insulation, so the efficiency of the heating system in the winter was not improved. We never got around to adding insulation before we moved, so I can't tell you what the difference would have been if we had. I can say that I'm a firm believer in adding radiant barrier to the attic. Either that or having the entire attic insulation with spray on foam insulation which would, in essence, make your attic part of the conditioned space. [/QUOTE]
