Our 10 year 2300sq ft old "energy star" home has had a number of cold rooms in the winter and warm in the summer. Our unfinished walk out basement with all the vent registers has been hot in the winter and cold in the summer. In order to keep my sons room somewhat warm during the winter we had to keep the majority of the registers closed on the first floor. My sons room and our master bathroom was generally 2 to 3 degrees cooler than the rest of the house. I contacted Victor after reading the reviews here and elsewhere. I must admit i was skeptical at first. Victor came in and did an assessment and found that my sons bedroom and our master bath had very little airflow coming out of the registers. He found numerous leaks in the main hvac ducts in pur basement. Keep in mind our hvac ducts had been taped when installed ten years ago. Much of the visible foil tape was coming away in numerous places throughout the basement. Victor and his team returned to begin the sealing process. Using an infrared heat gun Victor located three separate duct runs that were detached, one going to my sons bedroom, the other going to our master bedroom bathroom and a third going to our guest bedroom. Victor also located a phantom duct that was heating an insulated cavity between our garage and master bedroom floor. Victor was able to access two of the three vents from our garage, two of the ducts were missing screws to hold them together. One of the ducts was cut 3 inches to short when installed and the orignal hvac installer wrapped the ducts with foil tape that had essentially dried out and come away over the years. Victor removed the phantom floor heating/cooling cavity duct. He repaired the drywall he had to remove. Victor reattached the duct going to my sons room, again it was missing screws to hold the pipe together at an elbow in the basement. Victor began the sealing process, he ran a pressure test on our system, blocking all the registers with foam blocks. Our system had 443.7 CFM of leakage, the equivalent of an 83.8 sq inch hole. This number included the phantom duct at the time. After the sealing process Victor ran the same pressure test and the leakage was reduced to 5.5 CFM or the equivalent of a 1 inch hole. Victor then went around the house and measured the airflow coming out of each register and balanced the registers. The ducts in our problem rooms had a substantial increase in airflow. My sons bedroom is now the same temperature as my thermostat. Our master bathroom is now comfortable and the tile floor isnt freezing anymore. Victor had to partially open a number of the basement registers as the leaks in the hvac ducts were no longer heating the basement. We have not used the air conditioner as of yet but i am anticipating that we will be much more comfortable going forward. The actual sealing process took a few hours and did not make a mess. There was the slightest odour when the process was going on. Victor and his team were professional, courteous and Victor took the time to explain everything in detail. My only regret being that we didn't contact Victor years ago. I have recommend Victor's company Aeroseal Tech to a number of neighbours, family members and friends with very similar problems. Victor followed up with us to ensure there were no issues. Thank you again for making our home much more comfortable.
