We live in central Florida and purchased a new construction house in August 07, the electric bill are $400 - $500 a month in the warm weather, I think it's the AC running up the bill since the bills have gone down to around $200 right now.
Since the first bill I've been keeping the temperature at 78 degrees to try and control the electric costs but with summer approaching I going to to be an expensive year, or a hot one if I cannot figure this out.
The house is a ranch, block construction, blown insulation in the attic, what else? the ac unit duct work goes through the garage into the attic, the attic gets extremly hot, and so does the garage toward mid-afternoon, perhaps that's ok being Florida.
Do I need more attic insulation? I read about a radiant barrier?
Thanks for reading.
