Victor did a great job of answering all our questions about the product and the process. We have recently moved into our new home and with the first drop in outside temperature we felt the house was not keeping the same temperature in all the rooms. Plus my husband has allergies, and as soon as we started using the furnace his allergies began to bother him. Our first attempt was by doing duct cleaning, but it didn't really solve the issues. That's when I found out about the Aeroseal process. Victor answered all of our questions. It has been over a week and the improvements are amazing.
