Aeroseal Tech Inc.

We had hot rooms and could rooms, plus a big differential from the basement to the top level. We have three levels including the basement. We also had the two rooms furthest from the furnace upstairs get very little airflow. Hot in Summer; cold in Winter. Now these rooms have so much air the vents literally blow off. Rooms are better balanced. We tried many things before we sealed the ducts with aeroseal with many HVAC people looking and even had our furnace and AC changed. Nothing made a difference like sealing the ducts. High recommended .
