Homeowners in Stafford, VA had old, contaminated insulation in their attic that was ineffective. Over time, insulation can wear down. Old age, harsh weather conditions, and critters can degrade the material, rendering it pretty much useless.
The Comfenergy crew air sealed the attic and then installed fresh new cellulose insulation. Now it takes less energy to heat and cool this home, leading to lower utility bills and even temperatures throughout the house.
