Recently bought a house and had AVW install all the windows in our house. The old windows we got with the house were horrible and really needed replacing. We live about a block away from major road and the freeway. Got the Arizona package and was concerned that the windows would not block out the noise. The Arizona package was supposed to reduce energy bills. It's been three months since we've had our new windows. The outside noise levels has been reduced considerably but I've not noticed any reduced energy bills and we've been using the air conditioner as we had before the windows were installed, and that was only for one month, so I don't really have a comparison there. I have noticed more humidity in the house.
