I had the attic blanket and two solar fans installed in my home on 1-10-14. I have seen my utility bill decrease and cut my cost by 30%. It has cut my heating and cooling bill substantially. I can see it has saved on the wear and tear on my (HVAC) unit because it does not have to work as hard. The attic blanket has also eliminated hot and cold spots in my home. I have spoken to Brandon Lander and showed him copies of my utility bills where my cost has gone down from year to year. When I have my A/C unit serviced, the people who come to service my unit express how cool my attic is when they enter it. I am very pleased with the work that has been done and would recommend this to everyone.
