In the early winter of 2011 we decided that the insulation in our attic was insufficient. This was pointed out by a contractor who said we basically had no insulation. After a bit of procrastination, we bit the bullet and had our attic blown. I compared our natural gas bills and summer electric bills from previous years and there was a dramatic difference in the amount we paid, even with variance in weather between the two years. For instance, in the summer before our attic was blown, I would notice our inside temperature would rise late into the night. Now it stays cooler throughout the day and night, the summer heat doesn’t seep into our house.
The installer we used was Carolina Home Performance (contact info below). They were knowledgeable and have been doing this for two generations in a family owned business. We looked at several others. They explained that it would take a year or so to recoup the savings. I highly recommend. Also below is an example of the estimate they gave me.
