At first we were very skeptical about the whole Aeroseal process and our home is only 6 years old. After researching this product we decided to try because we have just retired and plan on staying in our home. We noticed a difference almost immediately after GreenHome finished the application. We had to lower the thermostat and our home felt much warmer. Another benefit we saw and felt was the increased air flow coming up further into the room from the registers.
Our heating and cooling gas bill has also been reduced.
