Building Science: Duct System Sealing and Size

Most ducts are too small for the size for the HVAC equipment installed. The average California home’s ducts leak in excess of 30%! This results in inefficiency and shortens the life of your furnace because it is forced to work harder than necessary to move air to various parts of your home.

A building performance contractor can run a simple test to measure the efficiency of your duct system and help to identify leaks. From there you can work to reseal or replace the most inefficient parts of the system and increase your HVAC system’s efficiency and lower your energy bill!
