Insulation Upgrade to R38 Using Blown In Fiberglass Insulation in Fresno, CA

The homeowner contacted us because their home was constantly hot and uncomfortable during the summer. In fact, they’d had an HVAC repair technician come out to service their air conditioner, thinking that was the issue. The HVAC technician let the homeowner know that their unit was operating normally, but their insulation was low. When we came out and took a look for ourselves, we found this was indeed the case. The attic had only about 3-4 inches of old insulation present. We determined that upgrading the insulation to an R38 level (14 inches of fiberglass insulation) was necessary to help the homeowner achieve her goals of keeping her home cool while also reducing her cooling costs.

We began by air-sealing visible leakage points with closed-cell foam. This helps to prevent air from traveling between the living spaces of the home and the attic. We then blew in premium, fiberglass insulation to a height of 14 inches.

As a result of the work we performed, the homeowner now enjoys a cool, comfortable home during the summer, a warmer home during the winter, and lower heating and cooling costs by up to 30% for as long as she lives in that house.
