I would highly recommend Attic Air. I found their customer service outstanding from start to finish. They installed insulation, an attic fan and routed our bathroom vents externally. I noticed a significant difference immediately as I did not need to run my A/C as often and my bedrooms upstairs were staying cooler for longer. If you have any attic or insulation needs, do not hesitate to give Attic Air a call.
