The project focuses on installing duct work and managing moisture through various systems. Bath fans are integrated with the main duct work and a whole house dehumidifier. Modifications to the ceiling include a soffit design for the fan vent. Hard pipe duct materials are chosen for durability. A garage fan is added to exhaust car fumes, controlled by a timed switch. The importance of separating bath fans from the ERV system is discussed, with future plans for installation and wiring details.
