Inverter Home Depot in Akron – What Is a Terminal Unit?
A terminal unit is an outlet in ductwork to allow air delivery to an environment like a room. The terminal unit taps into the ducts with a fan to push air out of the ductwork at varying speeds to control the environment. Terminal units may also have built in heating and cooling coils, depending on the installation.
A technician installs these components of a heating and cooling system during the initial process of setting up the system. If adjustments need to be made in the future, the technician can return to move or cut off terminal units.
In remodeling and retrofitting, it may be necessary to relocate terminal units. Unused sections of ductwork can be closed off so air does not flow through them, and a technician can create new connections and branches to accommodate the needs of the remodel. In cases where a building is substantially increased, the technician may need to retrofit the entire ducting system to address the change in size; narrow ducts designed for circulating sufficient air for a small space will not be up to the task of a radically larger one, or the airflow may not be efficient after the remodel.
A terminal unit commonly has a grating over the fan to keep material out of the ducts and reduce the risk of injuries caused by bumping up against the fan. Periodically, a technician or cleaner should remove the grating for cleaning. While it is exposed, the fan and duct can be cleaned as well. Reducing dust in the ductwork increases safety and will keep the air fresh and clean. In rare cases, bacteria can colonize ducts if they are kept warm and moist, and a deeper cleaning may be necessary.
