This service was part of my AC Furnace package purchased and was coordinated through the Project Manager of my HVAC installation. AEROSEAL came highly recommended and although I didn't know the company they were very professional from start to finish. The process took approx. 3 hrs though the Team worked quietly and would always be willing to stop and answer whatever questions I had during the process. They appeared very knowledgeable in their field and offered a lot of tips and advice regarding my airflow and even my humidifier. I appreciated the respect for my home and left the house with no dust or mess behind. They even set my carpets securely around the vents as well (Nice touch).
