View this new sensation in retrofit HVAC duct renovation, brought to us courtesy of Joe Gorman, President of JP Gorman in Rocklin, California. Two 2×4’s are skillfully screwed together with top quality brass zip screws to exert the exact amount of pressure on this flex duct run to enable it to deliver exactly zero air to the exceedingly uncomfortable room above.
We acknowledge the expertise and craftsmanship of this seasoned unknown carpenter and discourage the implementation of this new airflow management device supported by the February additions to the California Title 24 energy efficiency standards. This practice will save over 8 Gigawatts of power in California in 2009! But only if proper installation is verified by an official certified energy inspector.
Joe assures us this new damper system was removed when he renovated the duct system.
